潮水退去
The Tide Goes Out
每个时期都有一句恰如其分的引语来解释当时的情形,我常常发现自己借用这样的句子。沃伦·巴菲特贡献的此类引语远超常人;不仅他的洞察力无人能及,他表达洞察力的能力也同样出色。因此,从去年 7 月那句“一切皆好”开始,我频繁引用下面这句:
潮水退去时,我们才知道谁在裸泳。
毫无疑问,“裸泳”——或者连救生衣都没穿——完美描述了去年夏天结束前那段无忧无虑时期里投资者的行为。同样,潮水退去——以及那些行为被暴露——也概括了此后发生的种种令人不快的披露。2002 年底至 2007 年年中,金融业参与者沉溺于前所未有的杠杆、创新和冒险,其后果如今已显而易见。
杠杆与膨胀
回看过去几年,我们看到的是一个相当平常的经济增长与繁荣时期,伴随企业健康状况良好、盈利丰厚。但让这个时期与众不同的,是金融业活动的失控式繁荣。整个金融部门像气球一样膨胀,越来越多的热气被不断灌入。
推动 2002 年至 2007 年这轮繁荣的最大因素可能是杠杆;此前阶段,股权资本源源不断流入杠杆实体,同时放贷方也愿意提供前所未有的杠杆规模。如今,这一过程正在逆转,后果同样剧烈,却远没有那么令人愉快。让我们回顾一下那个常被描述并被奉为良性循环的过程:
For every period, there’s a quotation which serves perfectly to explain what’s going on, and I often find myself borrowing it. Warren Buffett provides more than his share; not only is his insight unmatched, but so is his ability to express it. Thus, starting with “It’s All Good” last July, I’ve found frequent use for this one: When the tide goes out, we find out who’s been swimming without a bathing suit. Certainly, “swimming without a bathing suit” – or perhaps a life preserver – serves beautifully to describe investor behavior during the carefree period that ended last summer. And equally, the ebbing of the tide – and the exposing of those who engaged in that behavior – sums up the unpleasant disclosures which have taken place since. Financial sector participants indulged in unprecedented amounts of leverage, innovation and risk taking between late 2002 and mid-2007, the consequences of which have become readily apparent. Leveraging and Inflating When we look at the last few years, we see a rather ordinary period of economic growth and prosperity, accompanied by good corporate health and profitability. But what distinguished this period from all others was a runaway boom in financial sector activity. The whole financial sector inflated, like a balloon into which increasingly more hot air was forced. The greatest contributor to the 2002-07 boom likely was leverage; the recent past saw a steady flow of equity capital to levered entities, accompanied by willingness on the part of lenders to provide unprecedented amounts of leverage. Now the reversal of that process is underway, with consequences that are equally dramatic but much less pleasant. Let’s review the process which was often described and embraced as a virtuous circle:
股权资本被提供给那些意在加杠杆的实体。债务唾手可得,它们借此扩充总资本,进而增强追逐利润的能力。这种资本组合被用于购置资产,推高了价格。得益于财务杠杆,价格上涨反过来又让这些实体的股权以更快的速度膨胀。
Equity capital was provided to would-be leveraged entities. Debt was readily available for them to use in expanding their total capital and thus their ability to pursue profit. This combined capital was used to purchase assets, forcing prices higher. Price appreciation caused the entities’ equity to expand at a faster rate thanks to their financial leverage.

净资产的增加伴随着借款的同步攀升。事实上,出色的业绩表现让放贷方确信,愿意为每 1 美元净资产提供更高的杠杆额度。这意味着这些实体能够以比股权投资流入和资产增值更快的速度扩张投资组合。
而且,由于这些高杠杆实体的盈利能力看似坚不可摧,风险厌恶情绪随之减弱,放贷方要求的风险溢价和回报率也逐步走低。杠杆因此变得更便宜,从而更具吸引力。
正如良性循环的典型特征,一切在某个阶段都运行顺畅:更多股权涌入,被日益放大的杠杆层层放大,买盘推动资产价格进一步上涨,上行螺旋不断延续。
The increases in equity were matched by further increases in borrowings. In fact, the good performance convinced lenders to increase the amount of leverage they would supply per dollar of equity. This meant the entities could grow their portfolios even faster than the rates at which equity capital flowed in and assets appreciated. Further, because of the seeming impregnability of the leveraged entities’ profitability, risk aversion shrank and the risk premiums and returns demanded by lenders declined. Leverage became cheaper and thus even more attractive. As is typical of virtuous circles, everything ran smoothly . . . for a while: additional equity flowed in; it was leveraged up increasingly; buying caused assets to appreciate further; and the upward spiral continued.
事情越走越顺,投资者越来越亢奋,像这样的循环似乎注定永不停歇。当然,它们不可能永续。但人们忘了这一点,而这正是通往过度循环的关键前提之一。高估上涨和下跌周期的持续时间,是投资者一再重复的错误之一。
去杠杆与通缩
多年来,我写过不少关于周期的备忘录,每次都试图提醒读者,树不会长到天上,成功之中自埋失败的种子。正如杠杆实体的气球在过去几年膨胀到失去理智,如今它已步入放气过程。而且,正如我在《那又怎样?》里提到的,空气泄出的速度总是比充入快得多。最终,过程中外生的变数会横插一脚,或者过程自身重量压垮自己。以眼下的次级抵押贷款为例——上面描述的过程原本顺风顺水,越来越大的房贷不断批出,覆盖购房成本的比例越来越高,而借款人信用资质却越来越差。到目前为止,一切安好:没有纪律或约束妨碍的进程。但必须明白,现实终将闯入。比如,借的金额最终会要求还款额超过借款人承受能力。哎呀,投资者忘了这一茬。
要理解现在发生的事,你只需把上述过程倒过来,再挤压一下——那股挤压的力量,正是通缩背后的推动力,源自过程缺陷暴露时伴随的痛苦。
With things working increasingly well and investors becoming more and more excited, processes like this one seem destined to go on forever. Of course, they cannot. But people forget that, satisfying one of the key prerequisites for a cycle that goes to excess. Overestimating the longevity of up legs and down legs is one of the mistakes that investors insist on repeating. Deleveraging and Deflating Over the years I’ve written a number of memos about cycles, and in each one I’ve tried to remind readers that trees don’t grow to the sky, and that success carries within itself the seeds of failure. Just as the balloon of levered entities expanded beyond reason in the last few years, now it’s well into the process of deflating. And, as I mentioned in “Now What?” the air always goes out a lot faster than it went in. Eventually, developments that are exogenous to the process interfere, or perhaps the process collapses of its own weight. In the current instance, consider subprime mortgages. The process described above was going along just fine, with increasing numbers of ever-larger mortgages being granted to cover a rising percentage of the cost of houses bought at rising prices by borrowers of declining creditworthiness. So far, so good: a process unhampered by discipline or restraint. But it must be seen that, eventually, reality will intrude. For example, eventually the amounts borrowed will necessitate payments that exceed what the borrowers can afford. Oops; investors forgot that part. To understand what’s going on now, all you have to do is reverse the process described above and squeeze (the squeeze – the force behind the deflating – comes from the pain that accompanies disclosure of the process’s flaws).
资产价格走弱,总有个由头。这时杠杆就反向发威,实体企业的股权缩水速度比资产价格下跌还快,借债对资产的比率一路上升。放贷方眼见资产价格滑坡,心里发慌,要么催着还贷,要么到期不续。有些情况下,这些实体的抵押品缩水后已经不够格,于是贷款被抽走。
Something causes asset prices to weaken. Now the leverage works in reverse, causing the entities’ equity to shrink faster than the rate of decline in asset prices, and their ratios of borrowings to assets to rise. Lenders, worried about declining asset prices, either call in their loans or refuse to roll over debt when it matures. In some cases, the entities’ now-shrunken collateral fails a

市值测试会触发追加保证金通知,而满足这一通知只能靠追加抵押品(通常手头没有)或出售资产(这会加剧市场疲软)。
此外,全球突然感觉风险加大,贷款方要求更高的风险溢价,推高了借款成本,进一步恶化借款方的经济状况。
股票投资者——被资产价格下跌、杠杆股权亏损和追加保证金通知的组合吓坏了——尽可能撤出股权资本。看到投资者在撤资窗口前排起长队,还常常被告知拿不回自己的钱,这种景象让负面氛围雪上加霜。
为了筹集现金满足贷款方和股权投资者的要求,资产价格承受更大下行压力,强化了这个突然形成的恶性循环。抵押品被贱卖又给这种压力添了一把火。
具体想想银行会怎样。在这种负面环境下,很难想象这些高杠杆机构还会放贷,原因有三:一是银行的股权在缩水,二是它们觉得自身可能也需要现金,三是它们担心贷款和资产进一步亏损。
market value test and triggers a margin call, which can be met only through the posting of additional collateral (which usually isn’t available) or sales of assets (which add to market weakness). Further, with the world suddenly feeling much riskier, lenders demand increased risk premiums, raising the cost of borrowed funds and further impairing borrowers’ economics. Equity investors – panicked by the combination of asset price declines, leveraged equity losses and margin calls – withdraw equity capital to the extent they can. The sight of investors lining up at the withdrawal window, and often being told they can’t have their money, adds to the negative climate. The need to raise cash with which to satisfy the demands of lenders and equity investors places further downward pressure on asset prices, reinforcing what is suddenly a vicious circle. Fire sales of collateral add to this pressure. In particular, think what happens to banks. In this negative environment, it’s hard to imagine these highly leveraged entities extending credit, given that (a) banks’ equity is shrinking, (b) they feel they may need the money themselves, and (c) they fear further losses on loans and assets.
这个恶性循环如今看起来和不久前的良性循环一样显而易见、不可避免,这并不令人意外。就在这个当口,我们可能会开始听到关于不可遏制的下行螺旋、金融体系即将崩溃的言论。不加质疑的狂热让位给了彻底的绝望。
按市值计价会计
如果你在电视上看过足够多的刑侦剧,就会知道调查可疑火灾的探员用“助燃剂”这个词,指纵火犯用来助长火势蔓延的化学物质。当前的资本市场周期被一个在 1990 年代加入资本市场方程式中的因素加速了:按市值计价会计。
在我四十年前进入的那个更简单但仍不完全稳定的金融世界里,稳定性是金融机构所追求的。举例来说,银行和保险公司可以在资产负债表上按成本持有贷款或债券,只要(a)该资产基本面没有受损,(b)打算持有至到期。即使市价暂时下跌,也假定信誉良好的债权到期时能全额偿付。因此,只要基本面稳健,价格波动就被忽略。
近年来,“透明度”“问责制”和“市场信号”变得更加受重视。这在很大程度上与安然等公司曝出的欺诈丑闻有关。结果是,会计规则日益要求资产按实际或估算的市场价格估值。我在 1990 年就预见过这一幕:当时,作为打击高收益债券行业(以及德雷克塞尔和米尔肯)的努力的一部分,储贷机构被要求按市价计算其持有的高收益债券——在价格疲软时期,这注定了其中许多机构的命运。
It shouldn’t come as a surprise that this vicious circle seems as obvious and inescapable as did the virtuous one just a short time earlier. This is the point at which we may start to hear talk about the unstoppable downward spiral and thus the pending collapse of the financial system. Unquestioning euphoria gives way to full-blown depression. Mark-to-Market Accounting If you watch enough cop shows on TV, you know that investigators of suspicious fires use the term “accelerant” for the chemical used by an arsonist to encourage the spread of a blaze. The current capital market cycle has been accelerated by an element that was added to the capital market equation in the 1990s: mark-to-market accounting. In the simpler but still not totally stable financial world I entered forty years ago, stability was desired in financial institutions. So, for example, banks and insurance companies were allowed to carry a loan or a bond at cost on their balance sheets as long as it was (a) fundamentally unimpaired and (b) intended to be held to maturity. Even if its market value fell temporarily, it was assumed that a creditworthy claim would be repaid in full at maturity. Thus, price fluctuations were ignored as long as fundamentals were sound. More recently, “transparency,” “accountability” and “market signals” became more highly prized. A lot of this had to do with skullduggery unearthed at companies like Enron. As a result, accounting increasingly came to require that assets be valued at actual or estimated market prices. I’d had a preview of this in 1990 when, as part of efforts to “get” the high yield bond industry (and Drexel and Milken), S&Ls were required to market price their holdings of high yield bonds – dooming many of them in a time of price weakness.

不存在完美的会计标准——只有不同选择,每一项在某个理想特性上更优,却在其他方面较弱。“成本”客观,但往往过时,且远非准确。“成本与市价孰低法”保守,但错误不对称。“市值”与时俱进,但并非总是可靠;它比安然公司更快地披露价值下跌,但也要求主观判断,并且会把可能只是一时的价格波动固化进账。因此,当会计监管机构强制推行按市价计价时,他们选择了当前性和透明性,却牺牲了有价证券的稳定性以及私人企业的客观性。(1988 年我们开始设立封闭式基金时,以及此后约十五年间,布鲁斯和我制定了一项政策:对私人企业按“成本计价,除非发生根本性、实质性且永久性的变化”。我们觉得这项政策对我们很管用。但自从安然事件和《萨班斯-奥克斯利法案》之后,我们就被禁止采用这种方法。如今基金被要求根据对每项资产价值的意见来定价。我们更喜欢老办法。现在谁受益更大?)
按市价计价会计如今成了当前繁荣/萧条周期的主要推手之一。在过去,银行(举个例子)会按成本持有资产。在本世纪头十年的上升年份里,由于银行被要求按市价计价,随着资产在良性循环中升值,银行得以扩张资产负债表,进而扩大经营。同样,如今资产价值收缩意味着银行的资产组合价值缩水,权益变小,能支撑的债务减少,从而放贷减少。贷款组合不得不压缩,新贷款无法发放。银行的监管资本可能变得不足;正是这一点,部分推动了银行向主权财富基金寻求再注资。
由于金融机构运作的环境同时具备刚性的监管资本要求、高杠杆、波动的资产价格,以及如今按市价计价的会计规则,它们在极端熊市中可能无法维持生存。(正如《华尔街日报》3 月 6 日所言:“对冲基金和银行有什么区别?银行杠杆更高。”)
1990 年,当高收益债券经历上述那番波折时(意味着利差扩大到 1100 个基点,且通过了一项法律,要求储蓄贷款机构在资产负债表上反映价格下跌),我被请去给 TCW 的董事会做风险简报。我讲了一个寓言,说的是一个受监管的金融机构在按市价计价会计的重压下破产。我对比尔·斯宾塞开玩笑——我在花旗银行工作时他担任行长——说在 1980 年代,如果花旗银行被要求在房地产贷款上确认按市价计价的损失,它可能也会破产。你猜怎么着:如今这正是规则。
这引出了我最喜欢的问题之一:一项资产的价格是什么?
There is no perfect accounting standard – just choices, with each alternative stronger on some desired traits but weaker on others. “Cost” is objective but often out of date and far from accurate. “Lower-of-cost-or-market” is conservative but asymmetrical in its error. “Market value” is contemporary but not always reliable; it discloses value declines faster than Enron did, but it also requires subjective judgments and bakes in price fluctuations that may prove transitory. So when accounting regulators mandated mark-to-market, they decided in favor of currentness and transparency but against stability with regard to marketable securities and objectiveness with regard to privates. (When we began to organize closed-end funds in 1988, and for about fifteen years thereafter, Bruce and I established a policy for valuing privates based on “cost unless there’s been a change which is fundamental, material and permanent.” We felt it served us well. But since Enron and Sarbanes-Oxley, we’ve been forbidden to use that approach. Now funds are required to price each asset based on opinions regarding its worth. We preferred the old way. Who’s better served now?) Mark-to-market accounting turns out to be one of the main contributors to the current boom/bust cycle. In the old days, a bank (for example) would have carried assets at cost. In this decade’s up years, since that bank was required to mark them to market, it was able to expand its balance sheet, and thus its operations, as assets appreciated in the virtuous circle. Equally, contracting asset values now mean the bank’s portfolio is worth less, and that its equity is smaller and can support less debt and thus less lending. Loan portfolios have to be reduced, and new loans can’t be made. A bank’s regulatory capital can become insufficient; it’s this, in part, that has been behind the banks’ trips to sovereign wealth funds for re-equitization. Since they operate in a world that combines rigid regulatory capital requirements, high leverage, fluctuating asset prices and, now, mark-to-market accounting, financial institutions can fail to be viable in extreme bear markets. (And as The Wall Street Journal of March 6 said, “What’s the difference between a hedge fund and a bank? Banks are more highly leveraged.”) In 1990, when high yield bonds had the brush with difficulty described above (meaning spreads widened to 1,100 basis points, and a law was passed that required S&Ls to reflect price declines on their balance sheets), I was asked to brief the board of TCW on the risks. I presented a parable about a regulated financial institution that went bankrupt under the weight of mark-to-market accounting. I joked with Bill Spencer, who was president of Citibank when I worked there, that in the 1980s, that could have been Citibank if it was required to recognize mark-to-market losses on real estate loans. Guess what: today that’s the rule. This raises one of my favorite questions: what’s an asset’s price?
你是指你想卖掉它时能拿到多少钱?
还是你想买下它时需要付多少钱?
是指买或卖 100 万美元的价钱,还是 1 亿美元的价钱?
Is it what you could get for it if you wanted to sell it? Is it what you would have to pay to buy it? Is it the price to buy or sell $1 million worth, or $100 million worth?

是指耐心地将单项资产单独出售所得到的价款,还是作为一大笔组合在一天内被迫清算所能拿到的价钱?是当今混乱市场中的价格,还是更平静时期的价位?若取后者,又由谁说了算?是高盛报的价还是摩根报的价?或者两者平均?倘若你发现雷曼的报价比它们两家都低,又该怎么办?资产并无交易时,价格又是什么?或者你全盘持有、无意出售,价格又当如何定义?
Is it the likely proceeds from the patient sale of an asset in isolation, or what you’d get for it as part of a large portfolio that has to be liquidated in one day? Is it the price in today’s chaotic market, or what the price would be in a calmer one? And if the latter, who says what that is? Is it Goldman’s price or Morgan’s? Or the average of the two? And what if you find out that Lehman’s is lower than both of them? What’s the price if the asset doesn’t trade? Or if you hold the whole thing and have no intention to sell?
我不知道答案。主要原因是根本没有答案。简而言之,一项资产没有“一个价格”。它有许多可能的价格,没有人能说清哪个才是正确的。洛杉矶一家珠宝商的广告用了这样一个醒目的标题:“保证估价更高。”换句话说,要么(a)他以低于其价值的价格出售珠宝(如果是这样,为什么?),要么(b)他以与其价值相符的价格出售,但保证估价会更高,这不禁让人对估价本身产生怀疑。在我看来,他所吹嘘的估价,与如今银行、对冲基金、CDO 和 CLO 给资产定价时使用的许多“市场价格”一样毫无意义。
有人开始表达一种观点,认为按市值计价会计准则——加上当今盛行的恶性循环——导致资产价值被低估,减记被高估,信贷危机被夸大。当然,我们有充分理由相信:
I don’t have the answer. Mainly because there is no answer. In short, an asset doesn’t have “a price.” It has many possible prices, and no one can say which is the right one. The ads for a jeweler here in Los Angeles lead with a great headline: “guaranteed to appraise for more.” In other words, either (a) he sells jewelry for less than it’s worth (and, if so, why?), or (b) he sells things for what they’re worth but guarantees they’ll appraise for more, which makes you wonder about the appraisals. The way I see it, the appraisals he touts are just as meaningless as many of the “market prices” being used today to price assets at banks, hedge funds, CDOs and CLOs. A view has begun to be expressed that mark-to-market accounting – in conjunction with the vicious circle that prevails today – is causing asset values to be understated, writeoffs to be overstated, and the credit crisis to be exaggerated. Certainly there’s every reason to believe that:
资产的价值正取决于人们愿意为它出多少钱(这本来就是定价的目标),但眼下愿意出手买入的人寥寥无几,市场价格就可能远低于其真实价值。在决定价格时,供需已经完全取代了基本面因素。由于交易寥寥,资产定价常常参照各类指数。可这些指数又因投机和对冲活动而剧烈波动,而且它们与正在定价的具体资产之间,可能根本没有多大关系。
放贷机构正将抵押品的估值基准从持续经营假设切换到清算假设。
追加保证金的通知引发抛售清算,抛售压低价格,价格下跌又触发更多追加保证金的通知。
Assets are being valued based on what people will pay for them (which is the goal), but with few people in a buying mood, market prices can far understate value. Supply and demand have completely supplanted fundamentals in determining prices. With little trading taking place, assets are often priced via reference to indices. But those indices fluctuate wildly in connection with speculation and hedging activity, and they may have little relevance to the individual asset being priced. Lenders are switching their valuations of collateral from going concern basis to liquidation basis. Margin calls are resulting in liquidations, which depress prices, leading to more margin calls.
实在难以相信,金融机构竟然会依据这些标准来评估自己万亿美元量级的资产负债表。但眼下我们还得继续接受按市值计价的会计规则。至少,你应该预料到它会持续不断地制造剧烈波动。相信我,它已经这么干了。
“应当”不等于“将会”
近来我很喜欢拿最近的事态作比:就像弗兰肯斯坦失控于自己创造的怪物,又像实验室里逃逸出来的人造变种。金融领域进行了大规模实验,把各种剧烈波动的元素以前所未有的方式组合在一起,比如杠杆、证券化、分层切割、衍生品——
It’s hard to believe these are really the bases on which financial institutions should value their trillion-dollar balance sheets. But we’re stuck for now with mark-tomarket accounting. At minimum, you should expect it to contribute extensively to continued volatility. Believe me, it already has. “Should” ≠ “Will” Lately I’ve enjoyed comparisons of recent developments to Frankenstein’s loss of control over his monster, or to a man-made mutation that has escaped from the laboratory. Extensive financial sector experimentation took place involving unprecedented combinations of volatile elements such as leverage, securitization, tranching, derivatives

以及逐市计值会计。在实验室里,实验性微生物会被隔离,直到其危害被完全了解。然而,在这个十年的金融市场上,它们却被迅速推广,并在全球兜售。
1998 年,长期资本管理公司成了复杂投资策略失灵并造成严重后果的典型代表。这家对冲基金投资于高度多元化的固定收益套利组合。这些情境中,两种相关资产的交易价格偏离了其正常价格关系:一种相对于另一种略微偏贵,超出历史数据显示的应有水平。长期资本管理公司以巨额杠杆大量买入这些微小的错误定价,期望它们会得到修正。据其创始人约翰·梅里韦瑟所言,其后来崩盘的解释很简单:“基金预期价差收敛而增加仓位,然而……交易却剧烈背离。”
多年来,这些备忘录一直引用我的好友布鲁斯·纽伯格的话:“不太可能发生的事时常发生,本该发生的事却常常落空。”当事情没发生时,过度依赖“本该发生”这一事实,可能会致命。这就是为什么我总提醒人们那个 6 英尺高的男人,他淹死在平均 5 英尺深的溪流里。你必须能够挺过低谷。你投资行动的成功不应依赖于常规结果占据上风;相反,你必须留出极端情况的余地。近期崩盘的故事中包括多起灾难,起因便是事情并未如预期那样运转:
and mark-to-market accounting. In the lab, experimental microbes would be quarantined until their dangers were fully understood. In the financial markets of this decade, on the other hand, they were rapidly popularized and peddled world-wide. In 1998, Long-Term Capital Management became the poster child for the ability of sophisticated investment strategies to malfunction with grave consequences. This hedge fund invested in a highly diverse portfolio of fixed income arbitrage positions. These were situations where two related assets were trading in violation of their normal price relationship: one was a little more expensive relative to the other than history said it should be. LTCM bought into these small mispricings in large quantities, on enormous leverage, in the expectation that they would correct. The explanation for its subsequent meltdown was simple, according to the founder, John Meriwether: “The Fund added to its positions in anticipation of convergence, yet . . . the trades diverged dramatically.” For years these memos have quoted my good friend, Bruce Newberg, as saying, “Improbable things happen all the time, and things that are supposed to happen often fail to do so.” Acting in excessive reliance on the fact that something “should happen” can kill you when it doesn’t. That’s why I always remind people about the 6foot-tall man who drowned crossing the stream that was 5 feet deep on average. You have to be able to get through the low points. And the success of your investment actions shouldn’t depend on normal outcomes prevailing; instead, you must allow for outliers. Recent tales from the bust include a number of disasters that arose because things didn’t work as they were supposed to:
按理说,违约事件应当彼此独立,但当全国各地的房贷借款人几乎同时开始违约时,与次贷相关的证券便应声崩塌。拍卖利率票据本应兼具长期融资(资金永久性)和短期融资(低利率)的双重好处,因为频繁的利率重设应当消除持有固定利率长期债务所伴随的价格风险。但当拍卖无人问津时,重设机制便失灵了。在 2007 年第二季度商业地产最火热的时候,房地产投资者愿意以 3.5% 的现金收益率买入纽约的办公楼(而借款成本是 5.5%),原因无外乎是:(a)租金应当翻倍到每年每平方英尺 150 美元,或者无论如何,(b)总会有别人愿意出更高的价钱接盘。但到目前为止……并没有。“绝对收益基金”本应提供稳定回报,不受市场波动影响。结果却发现,只有完全对冲的工具才与市场毫无关联,而眼下,一只不错的绝对收益基金可能只做到跌幅减半就算合格。伦敦一家名为 Peloton 的对冲基金在 2007 年涨了 87%,并于 1 月获评年度信贷对冲基金。它持有的 AAA 级抵押贷款多头头寸本应比次贷空头头寸表现得更抗跌。但今年 AAA 级债券也在下跌,而它借钱加杠杆买得太多,最终在 2 月让基金彻底崩盘。信用违约互换本应是转移信用风险的绝佳工具,但市场却失控了——在 6 万亿美元的债券背后,竟有 40 多万亿美元的保险覆盖。
Although defaults should be independent, subprime-related securities collapsed when mortgage borrowers all over the country began to default at the same time. Auction rate notes should have delivered the benefits of both long-term financing (permanence) and short-term financing (low rates), because frequent rate resets should have eliminated the price risk that accompanies fixed-rate long-term debt holdings. But the reset process failed to work when the auctions attracted no bidders. At the top in commercial real estate during the second quarter of 2007, real estate investors were willing to buy New York office buildings at 3½% cash yields (with money borrowed at 5½%) because (a) rents should double to $150 sq. ft./year or, anyway, (b) someone else should be willing to pay more for it. So far . . . no. “Absolute return funds” should provide steady returns without vulnerability to market fluctuations. It turned out, however, that only completely hedged vehicles are completely without market correlation, and now a good absolute return fund may be one that goes down only half as much. A London hedge fund called Peloton gained 87% in 2007 and was named Credit Hedge Fund of the Year in January. Its long positions in AAA mortgage paper should have continued to hold up better than its subprime shorts. But the AAAs declined this year, and they’d bought enough on leverage to make the fund melt down in February. Credit default swaps should serve as a great way to transfer credit risk. But the market grew out of control – to $40-odd trillion of insurance coverage on $6 trillion

债务——没有人知道最终结果会如何。当信用违约互换在市场上交易时,购买保障的人无从知晓他们的保险公司资本是否充足。因此,转移信用风险的努力可能只是用“对手方风险”替代了原有风险。
显然,投资者之所以投资,只是因为预期能够获利,他们的分析将集中于可能的情景。但他们绝不能只盯着预期发生的情况而排除其他可能性……以致承受过多的风险和杠杆,最终被不利结果击垮。
然而,与此同时,很难判断应当考虑的可能性范围有多广。没有任何投资行动能抵御所有可能的发展。除了全盘损失之外,是否真的存在所谓的“最坏情况假设”?我经常发现自己问起投资中的一个经典问题:我们该投入多少精力和资本,来为不太可能发生的灾难做准备?
近期许多问题的出现,是因为投资者预期的结果与实际发生的不符。他们是过于乐观了吗?还是环境本身就抛出了无人应当被期望应对的意外球?
杠杆与风险
关于杠杆和风险,应当秉持两条重要的投资原则:第一,杠杆放大结果,但并不增加价值。这句话我说得太多了,早该打住。但只需提醒几句:
of debt – and no one knows just how it’ll all work out. When CDS are traded around, the people who bought coverage have no way of knowing if their insurers’ capital is adequate. Thus, efforts to off-load credit risk may have replaced it with “counterparty risk.” Clearly, investors only make investments because they expect them to work out, and their analysis will center on the likely scenarios. But they mustn’t fixate on that which is supposed to happen to the exclusion of the other possibilities . . . and load up on risk and leverage to the point where negative outcomes will do them in. At the same time, however, it’s very hard to figure out how broad the range of considered possibilities should be. No investment action can withstand every possible development. Is there really such a thing as a “worst case assumption” short of a total loss? I often find myself asking one of the classic questions in investing: How much effort and capital should we devote to preparing for the improbable disaster? Many of the recent problems occurred because investors expected outcomes other than the ones that arose. Had they been too optimistic? Or did the environment simply throw curves that no one should have been expected to handle? Leverage and Risk Two important investment principles should be embraced concerning leverage and risk: First, leverage magnifies outcomes but doesn’t add value. I’ve said that so often that I ought to stop. But just a few reminders:
杠杆既放大收益,也放大亏损。在拉斯维加斯,人们常说:“下注越多,赢了就赢得越多。”但这话总忘了补上一句:“……输了也输得越多。”杠杆不过是把注下得更大的一种方式。
Leverage magnifies losses as well as gains. In Las Vegas, they say, “The more you bet, the more you win when you win.” But they always forget to add “. . . and the more you lose when you lose.” Leverage is just a way to bet more.
杠杆会放大结果,但不会增加价值。它会让高点更高、低点更低,甚至可能提高预期值……前提是结果处于正常范围。但它无法让一项投资本质上变得更好。因此,杠杆绝对无法等同于通过选股技巧或重组公司运营、财务所贡献的回报。
Leverage magnifies outcomes but doesn’t add value. It will make for higher highs and lower lows, and it might even produce an increase in the expected value . . . assuming outcomes are normal. But it can’t make something a fundamentally better investment. Thus, leverage absolutely cannot be equated to the contribution to return that comes from skill in selecting investments or in restructuring company operations or finances.
人们时不时会设计出一些结构,声称能在不相应增加下行风险的情况下增强投资的上行空间。这些结构很少奏效。或者,更准确地说,指望它们在不扩大结果范围和损失风险的前提下提高预期回报,是毫无道理的。你可能能把一项承诺回报率为 10% 的投资,变成一个有 90% 概率赚取 13%、10% 概率血本无归的工具。但你能
From time to time, people come up with structures that are purported to add to an investment’s upside without adding proportionally to its downside. They rarely work. Or, expressed properly, it makes no sense to expect them to enhance the expected return without increasing the range of outcomes and the risk of loss. You may be able to take an investment with a 10% promised return and turn it into a vehicle that has a 90% chance of earning 13% and a 10% chance of losing everything. But can

你最终得到的是预期回报更高、风险却不更大的东西?这好得不像是真的。
you end up with something that has a higher expected return but isn’t riskier? That’s too good to be true.
最后,杠杆除了放大盈亏之外,还附带一种下行中的额外风险,而这种风险并不会被随之而来的上行收益所抵消:那就是毁灭风险。杠杆叠加亏损,可能触发追缴保证金,导致崩盘。这背后没有任何相应的好处。如今,这个教训正被深刻吸取。
Finally, in addition to magnifying losses as well as gains, leverage carries an extra risk on the downside that isn’t offset by accompanying upside: the risk of ruin. Leverage, when added to losses, can lead to margin calls and meltdowns. There is no corresponding benefit. This lesson is being well learned today.
其次,每项投资或投资组合都承载着多种风险,其总体风险即为这些风险之和。
每项投资既包含与个别公司或资产相关的特定风险,也包含作为市场一员所固有的系统性风险——即其贝塔值。此外,还可能存在流动性风险、法律风险、货币风险和政治风险。最后,风险还源于资产被持有的结构方式。这里我指的是伴随杠杆而来的风险。
为简化当前讨论,风险源于你所购资产与融资方式的组合。你可以购买高风险资产,但若不加杠杆,绝不会因追加保证金通知而失去它们。或者,你可以购买基本面安全的资产,但足够的杠杆加上足够恶劣的环境,可能导致崩溃。换言之,投资“安全”资产未必安全,尤其是在借款购买的情况下。
我们近期已目睹此类现象,投资于顶级优质资产的实体陷入困境。例如,凯雷资本公司投资于两家政府支持住房机构房利美和房地美的 AAA 级债务。但它将股本杠杆放大了 31 倍,仅凭 6.7 亿美元股本购买了 217 亿美元证券。这意味着,若资产价值下跌 3%,其股本将归零。忧虑的银行收紧了贷款;凯雷资本收到无法满足的追加保证金通知;银行没收其资产;基金随之崩溃。
投资安全并非源于做安全之事,而是讲究方式地去做。换言之,任何事物都可能因使用过高的杠杆而导致波动无法承受,最终毁于一旦。这就是为什么在撰写关于长期资本管理公司的《天才不够》(1999 年 1 月)时,我说杠杆加波动等于炸药。
金融自毁
近五年来戏剧性的周期性上升阶段(我指的是 2002 年 11 月至 2007 年 6 月),以及自去年夏天开始的更短暂但同样戏剧性的下行阶段,都让我有机会反思诸多现象并汲取教训。你们已在过去三份备忘录(《这次不同》、《现在怎么办?》和《谁干的?》)中看到了结果。基于将若干独立观察联系起来,我对某些事物的运作方式有了新看法。
Second, every investment or portfolio entails a variety of risks, and its overall risk is the sum of those. Every investment embodies both the specific risk related to the individual company or asset and the systematic risk that is a function of its membership in a market – its beta. There also can be liquidity risk, legal risk, currency risk and political risk. Finally, risk is introduced by the structure in which an asset is held. Here I’m referring to the risk that comes with leverage. To simplify for my current purpose, risk comes from the combination of what you buy and how you finance it. You can buy very risky assets, but if you don’t lever up to do so, you’ll never lose them to a margin call. Or you can buy fundamentally safe assets, but the combination of enough leverage and a sufficiently hostile environment can cause a meltdown. In other words, investing in “safe” assets isn’t necessarily safe, particularly if you’ve borrowed to buy them. We’ve seen this at work in recent days, as entities that invested in top-quality assets have run into trouble. For example, Carlyle Capital Corp. (“CCC”) invested in AAA-rated debt of the two government-sponsored housing agencies, Freddie Mac and Fannie Mae. But it levered its equity 31 times to do so, buying $21.7 billion of securities on the basis of just $670 million of equity. That meant that if values declined 3%, its equity would be gone. Worried bankers pulled back their loans; CCC received margin calls it couldn’t meet; the banks seized its assets; and the fund melted down. Investment safety doesn’t come from doing safe things, but from doing things safely. Put another way, anything can be screwed up by using so much leverage that its fluctuations can’t be survived. That’s why, in writing about LTCM in “Genius Isn’t Enough” (January 1999), I said leverage + volatility = dynamite. Financial Self-Destruction The dramatic cyclical up leg of nearly five years (I’d say November 2002 through June 2007), as well as the far shorter but equally dramatic down leg that started last summer, have given me opportunity to reflect on a number of phenomena to be noted and lessons to be learned. You’ve seen the results in the last three memos (“No Different This Time,” “Now What?” and “Whodunit”). I’ve reached a new view of how some things work, based on tying together several separate observations.

我曾指出,模型之所以可能失效,原因之一在于市场是动态的,而非静态的。通过反复练习,你可以逐渐精通一座高尔夫球场,因为你会学到每个动作的后果,从而知道哪些是正确的选择:如果把球打到 A 点,它会滚向球洞;而打到 B 点,则会滚向水塘。最终掌握是可能的,因为球场不会因你的击球而改变。但指望靠某种策略去掌控市场,则是徒劳的,因为市场由参与者塑造,因此它会回应、会变化。没有任何投资行动方案——哪怕执行得完美无缺——能适用于所有市场、所有时代。事实上,当一种方法被过度接受时,普遍依赖它反而会成为危险的根源。
I’ve pointed out that one of the reasons models can fail to work is because markets are dynamic, not static. Through frequent play, you can increase your mastery over a golf course, as you learn the consequences of each action and thus which are the right ones: if you hit the ball to spot A it’ll roll toward the hole, whereas if you hit to spot B it’ll roll toward the water. Eventual mastery is possible because the golf course doesn’t change in response to your play. But fixing on tactics through which to master a market is unavailing, because the market is shaped by those who participate in it, and thus it responds and changes. No course of investment action – even if executed perfectly – can be right for all markets and all times. In fact, when an approach becomes too well accepted, the widespread reliance on it becomes a source of danger.
我在华尔街金融产品创新上着墨甚多。创新在牛市行情中成为可能,那时乐观的投资者:
I’ve devoted a lot of ink to Wall Street’s innovation of financial products. Innovation becomes possible in up markets, when optimistic investors: o o o o
他们思考什么可能行得通,而不去考虑失败的几率有多大,
愿意给新事物一个机会,暂且相信它的好处,
被早期轻而易举的成功所打动,并且
害怕因为没能模仿那些享受着这些成功的竞争对手而承受后果。
think about what might work and dismiss the likelihood of failure, are willing to give something new the benefit of the doubt, are impressed by early, easy successes, and fear the consequences of failing to emulate competitors who enjoy those successes.
过去五年间,这些因素助长了前所未有的金融创新,量化分析师们向潜在投资者保证,可能导致新产品失效的“肥尾”事件极不可能发生。
In the last five years, these factors abetted unprecedented financial innovation, as quants assured prospective investors that the “fat-tail” events that could cause the new products to fail were most unlikely to occur.
但量化专家们的预测通常围绕“事件大概率落在正常区间内”展开,而过去九个月却让所有人有机会亲眼目睹极端情况的发生。这始于去年夏天,当时“一生一遇的事件”变得司空见惯。高盛首席财务官戴维·维尼亚尔或许会因八月的一番话而被铭记:“我们接连几天目睹了 25 个标准差级别的波动。”百年一遇的洪水变成日常现象,实属罕见,但有时候确实会发生。
But while the quants’ predictions usually center on the high probability that events will fall within the normal range, the last nine months have given all of us the opportunity to witness events at the extreme. This started last summer, when “once-in-a-lifetime events” became common. David Viniar, CFO of Goldman Sachs, may be remembered for saying in August that “we were seeing things that were 25standard deviation moves, several days in a row.” It’s unusual for 100-year floods to become daily occurrences, but sometimes they do.
最后,我还想提醒读者们,过去那些牛市中的创新项目,承诺带来奇迹,却往往在熊市考验中失败。其中最为人熟知的一个就是“投资组合保险”。这是一种基于统计学的技术,宣称能在不相应增加风险的情况下扩大股票敞口。其原理是通过计算机自动生成卖出指令,在市场下跌时即刻执行,从而迅速降低投资组合的风险。投资组合保险在“黑色星期一”之前曾风靡一时。但到了 1987 年 10 月 19 日,美国股市暴跌 20%,忙碌的经纪人顾不上接电话,卖出指令无法执行,投资组合保险从此销声匿迹。
Finally, I’ve reminded readers about past bull market innovations that promised miracles but often failed when tested in bear markets. One of the most easily recognized of these is “portfolio insurance.” PI was a statistically derived technique that would enable equity exposure to be increased without a commensurate increase in risk. This was made possible by a process through which computer-generated sell orders would be implemented automatically in the event of a market decline, instantaneously scaling back portfolio risk. PI had its heyday in the period just before “Black Monday.” But then, on October 19, 1987, the U.S. stock market declined 20%; beleaguered brokers didn’t answer their phones; the sell orders weren’t implemented; and PI ceased to be heard of.

几个月前,黑色星期一二十周年纪念让我有机会反思投资组合保险的短暂生命。我开始思考——现在我已深信——投资组合保险的失败并非因为黑色星期一碰巧发生。相反,它推动了黑色星期一的发生,也因此促成了自身的覆灭。在我十二月的备忘录《这次没什么不同》中,我列出了 2007 年的十二条教训。第四条说:“对风险的普遍漠视会制造巨大风险。”就这一点而言,1987 年,人们普遍相信可以在不相应增加风险的情况下提高股票敞口,这导致股票配置出现了不合理且不可持续的扩张。这种无忧无虑的买入推高了股价,而回调的可能性也随之越来越大。当标普 500 指数在黑色星期一之前的周三至周五下跌 10%,投资组合保险的用户们利用周末仔细思量之后,似乎得出了结论:他们承担的风险太大了;不能指望投资组合保险来拯救他们;必须大规模抛售股票。因此,这一创新并非毁于偶然事件。它的覆灭是由一个它自身至少在部分程度上促成的事件带来的。
创新通常需要乐观的假设,因此在牛市时期很容易大行其道。那些乐观的假设增加了环境中的风险,当最终被证明过于美好时,就会造成损失和产品的失败。上涨的潮水所鼓励的裸泳者,在退潮时无疑会暴露无遗。但我还要进一步说:在市场这个动态环境中,裸泳最终可能引发退潮。
一种新型危机
人们问我,现在的情况是否似曾相识,这次周期与我经历过的其他周期相比如何。我告诉他们,这次无论从程度还是性质上都不同。
过去我们也经历过崩盘,但从未如此广泛而具有系统性。早先的崩盘源于特定部门或地区的问题:1990 年的杠杆收购债务、1992 至 1994 年的房地产、1997 至 1998 年的新兴市场,以及 2000 至 2002 年的科技/电信股。大多数人宁愿看到疲软集中在特定领域……这样就能被控制、被治疗、被回避。
这次崩盘并非以部门为基础,尽管它最初由次贷危机引爆。相反,它源于我一直在讨论的那些技术的广泛应用:杠杆、证券化、分层和衍生品。由于华尔街以多种方式运用这些技术,当前的问题具有普遍性和弥漫性,能够在广泛领域造成损失,而无论基本面如何。
当前这场崩盘是在基本面健康的背景下爆发的。经济在增长。商业地产并未过度建设。债券违约率处于历史低位。然而这些领域却发生了巨额减记。因此,解决方案不会来自……
A few months ago, the twentieth anniversary of Black Monday gave me the opportunity to reflect on the short life of portfolio insurance. I began to think – and now I’m convinced – that PI didn’t fail because Black Monday just happened to occur. Rather, it contributed to Black Monday’s occurrence, and thus to its own demise. In my December memo “No Different This Time” I listed twelve lessons of 2007. Number four said that “widespread disregard for risk creates great risk.” In that way, in 1987 the widespread belief that equity exposure could be increased without similarly increasing risk led to an unjustified – and unsustainable – expansion of equity allocations. And the carefree buying this generated led to elevated stock prices from which a retreat was increasingly likely. When the S&P 500 fell 10% on the Wednesday-Friday leading up to Black Monday and users of PI had the weekend to think things over, it seems they concluded that they had accepted too much risk; that they couldn’t depend on PI to save them; and that they had to dump stocks en masse. Thus, this innovation was not undone by a chance event. Its undoing was brought about by an event which it had, at least in part, caused. Innovation generally requires bullish assumptions, and thus it’s easily accomplished in bullish times. Those optimistic assumptions add to the risk in the environment, and when eventually proved to be too rosy, they contribute to losses and to the products’ failure. The naked swimming which is encouraged by the rising tide certainly is exposed when the tide goes out. But I’d go further: in the dynamic environment of the marketplace, naked swimming eventually can cause the tide to go out. A New Kind of Crisis People ask me whether things look familiar, and how this cycle compares to others I’ve experienced. I tell them this one’s different in both degree and kind. We’ve had collapses in the past, but never so broad-gauged and systemic. The earlier ones were the result of things going on in specific sectors or regions: LBO debt in 1990, real estate in 1992-94, emerging markets in 1997-98, and tech/telecom stocks in 2000-02. Most people would prefer to see the weakness centered in specific areas . . . and thus containable, treatable and avoidable. This bust isn’t sector-based, although it was ignited first in subprime mortgages. Instead, it stems from the broad application of the techniques I’ve been discussing: leverage, securitization, tranching and derivatives. Because Wall Street applied those techniques in so many ways, the current problems are generalized and pervasive and have the ability to cause losses in a wide variety of areas, irrespective of the underlying fundamentals. The current bust arose against a backdrop of healthy fundamentals. The economy was growing. Commercial real estate wasn’t overbuilt. Bond defaults were at record lows. Yet huge markdowns have taken place in these areas. Thus the solution will not come

但问题并非仅限于局部的基本面缺陷。相反,这一难题如多头蛇般蔓延,因传染效应波及广泛领域。拉里·萨默斯对此有精辟论述:
当前同时存在三个恶性循环。流动性恶性循环——资产价格下跌引发抛售,抛售又加剧价格下跌;凯恩斯式恶性循环——人们收入下降导致消费减少,进而使他人收入下降、消费进一步萎缩;以及信贷加速器效应,即经济损失引发金融问题,金融问题又反过来加剧实体经济困境。
经济与市场的运行并无现成的图解公式,并非“只要做了 A,结果必然是 B”。对当前这场危机尤其如此,因为催生危机的某些金融技术尚属新颖;另一些虽曾使用,但从未达到如此规模;而它们近年来的组合运用更是史无前例。尤为关键的是,经济与市场的运行很大程度上取决于心理因素,而心理绝非如硬件般固定不变。因此,试图化解这场溃败的人只能基于假设摸索前行。
美联储与政府决心解决问题,但要想顺利走出困局,恐怕难逃阵痛。正如我在《谁干的?》一文中所写,为使资本配置决策高效运转,一个旨在创造资本的经济体系,必须时常经历资本毁灭的过程。若一味回避痛苦,只会让未确认坏账等问题拖延不决,反而推迟解决方案。我虽非专家,但依我之见,下行过程中的痛苦程度,至少应与此前繁荣期人人感受到的愉悦相当。
除等待时间流逝外,化解信贷紧缩——若确有化解之道——或许在于打断前述去杠杆进程。为此,当局将设法促使人们:
from addressing localized fundamental problems. Instead, the problem is hydra-headed, affecting a large number of areas due to contagion. Larry Summers put it this way: You have three vicious cycles going on simultaneously. A liquidity vicious cycle -- in which asset prices fall, people sell and therefore prices fall more; a Keynesian vicious cycle -- where people's incomes go down, so they spend less, so other people's income falls and they spend less; and a credit accelerator, where economic losses cause financial problems that cause more real economy problems. There is no schematic diagram for the workings of the economy and the markets, as in “if we do A, the result will be B.” That’s particularly true for the current crisis, since some of the financial techniques that gave rise to it are new; others haven’t been used to the same extent; and they’ve never been combined as they were in the last few years. In particular, the workings of economies and markets depend heavily on psychology, which can’t be treated as if it’s hard-wired. Thus the people trying to address this bust can only work from hypotheses and try possibilities. The Fed and the administration are determined to solve the problem, but we’re unlikely to have the unwind we need without pain. As I wrote in “Whodunit,” in order for efficient capital allocation decisions to be made, an economic system that aims to create capital has to witness capital destruction from time to time. Efforts to avoid the pain would cause problems like unrecognized bad loans to linger, delaying a solution. I’m no expert, but it makes sense to me that the quantum of pain on the way down has to at least approach the pleasure everyone felt during the boom. Other than just through the passage of time, the solution to the credit crunch – to the extent there is one – might be found in short-circuiting the deleveraging process described on pages 2 and 3. Thus, the authorities will try to get people to:
正视现实,承认并核销问题资产;即便资金用途看似前景黯淡,仍要举债;尽管资本稀缺、损失风险重重,仍要放贷;即便价格似乎只会愈走愈低,仍要买入被低估的资产。
face the music by recognizing and writing down problem assets, borrow money, even though the possible uses for it may seem ill-fated, make loans, despite the scarcity of capital and the risk of loss, and buy assets that are underpriced, even though prices seem only to go lower.
降息让借贷成本更低,而且还有更多降息空间。向银行放贷能为它们提供可转手贷出的资金。政府允许房利美和房地美发放更大额贷款的决定,应能为资金匮乏的住房市场注入资本。如有必要,政府为这两家机构提供兜底将收效更大(但也会带来道德风险)。暂停资本要求,能让受监管的金融机构进行资产减记、清理资产负债表,而无需担心跌破最低资本标准。它们甚至可能尝试暂停按市值计价会计规则。
Interest rate cuts have made borrowing cheaper, and there will be more. Loans to banks will give them money they can turn around and lend. The government’s decision to let Fannie Mae and Freddie Mac make bigger loans should make capital available in the starved housing market. If necessary, a government backstop of the agencies would do even more (but it also would introduce moral hazard). A holiday from capital requirements would allow regulated financial institutions to take writeoffs and clear their balance sheets without having to worry about falling below minimums. They might even try suspending mark-to-market accounting.

美联储最近宣布,将以国债置换那些交易不畅的 AAA 级抵押贷款债务,这正是试图遏制去杠杆化进程的举措。若事态如美联储所愿,这一置换应能:
The Fed’s recent announcement that it will swap Treasury securities for AAA-rated mortgage debt that isn’t trading well is such an attempt to stem the deleveraging process. If things go as the Fed hopes, this exchange should:
将部分抵押贷款证券退出流通,改善供需平衡,缓解价格下行压力;
让持有和购买抵押贷款证券变得更具吸引力,尤其是让交易商更愿意维持库存并为其做市;
压低收益率,从而降低经济中的资金成本;
为机构提供可借款(进而放贷)的抵押品。
take some mortgage paper out of circulation, improving the supply/demand balance and relieving the downward pressure on prices, make it more palatable to hold and buy mortgage paper and, especially, for dealers to maintain inventories and make markets in it, reduce yields, and thus the cost of money in the economy, and give institutions collateral against which they can borrow (and then lend).
另一方面,贝尔斯登的崩塌揭示了一些重要的局限性。经纪商,如同其他金融机构,是高度杠杆化的实体。其资产的性质决定了它们无法按需偿还负债。因此,一旦信心丧失引发“挤兑”,没有一家能幸免于难。正如我在“奔向谷底”一文中所言,它们提供的都是同一种产品——说白了,就是钱——一旦信心下滑,没人会说:“好吧,我有 5% 的可能性失去资本,或是暂时无法动用,但因为他们产品太优越,这风险值得承担。”谁会在信心下滑时留存?没有人。那么,哪家金融机构绝对不可能成为信心危机的对象?答案留给您自己想了。
这场危机何时终结?
我小时候,有很多漫画画着人举着三明治广告牌(还有谁记得那是什么?),上面写着“世界末日就在眼前”。但迄今为止,他们都错了。同样,人们说我们在 1987 年黑色星期一和 1998 年长期资本管理公司崩溃时已接近金融体系的终结。但我们现在还在这里。尽管有各种把事情搞砸的尝试,我们似乎还是跌跌撞撞地走过来了。我猜我们会一直这样。
像我这样爱操心的人,很容易去想那些末日般的可能性。但这毫无益处,所以我已不再去想。我能构想出“中国综合征”式的理论,但(a)我无法给它们很高的发生概率,(b)我也做不了什么。如果为了防范金融体系崩溃而做的准备,结果却是别的结局,那这些准备就是巨大的错误……而别的结局可能性很大。
The collapse of Bear Stearns, on the other hand, illustrates a few important limitations. Brokers, like other financial institutions, are highly leveraged entities. The nature of their assets makes it impossible for them to repay their liabilities on demand. Thus, none can survive a “run on the bank” stemming from a loss of confidence. As I said in “The Race to the Bottom,” they all offer the same product – basically, money – and if confidence declines, nobody will say, “Okay, there’s a 5% chance I’ll lose my capital, or access to it for a while, but it’s worth it because their product is so superior.” Who’ll stay despite a decline in confidence? No one. And what financial institution absolutely can’t be the subject of a loss of confidence? I’ll let you answer that. Where Will It End? When I was a kid, there were a lot of cartoons showing men carrying sandwich boards (who remembers what they were?) that said, “The end of the world is at hand.” So far, though, they’ve been wrong. Likewise, people said we had approached the end of the financial system around Black Monday in 1987, and when LTCM melted down in 1998. But we’re still here. It seems we muddle through, despite all attempts to screw things up. It’s my guess we always will. It’s tempting for worriers like me to consider apocalyptic possibilities. But it’s not productive, so I’ve quit. I can come up with “China Syndrome” theories, but (a) I can’t give them a high probability of coming to pass, and (b) there’s little I can do. The things one would do to gird for the demise of the financial system will turn out to be huge mistakes if the outcome is anything else . . . and chances are high that it will be. *

幸运的是,我职业生涯中最宝贵的教训之一出现在 20 世纪 70 年代初,那时我了解到了牛市的三个阶段:
Fortunately, one of the most valuable lessons of my career came in the early 1970s, when I learned about the three stages of a bull market:
第一阶段,当少数有远见的人开始相信情况会好转时;
第二阶段,当大多数投资者意识到改善确实在进行中时;
第三阶段,当所有人都确信情况会永远好下去时。
the first, when a few forward-looking people begin to believe things will get better, the second, when most investors realize improvement is actually underway, and the third, when everyone’s sure things will get better forever.

第一个阶段买入能带来丰厚回报,而最后一个阶段买入则会让你和羊群一起跌下悬崖。
2002 年至 2003 年,价格低迷,愿意买入的人相对较少。但随着 2004 年到 2005 年价格上涨、便宜货变得稀缺,买入行为增多,到 2006 年和 2007 年上半年,节奏变得狂热。这一趋势在投资者投入美国收购基金的资金激增中可见一斑:
Buying during the first stage can be highly profitable, while buying during the last will carry you over the cliff with the rest of the herd. Relatively few people were eager to buy at the depressed prices of 2002-03. But buying grew in 2004-05 as prices rose and bargains became scarcer, and the pace became fevered in 2006 and the first half of 2007. This trend was captured in the soaring amounts investors committed to U.S. buyout funds: 2002-03 2004-05 2006-07
$ 52 billion
200
557
$ 52 billion 200 557
收购资本的增长受到高报告内部收益率(IRR)的推动,而后者又得益于股息再资本化和快速转手,这本身就是资本市场环境日益过热的一个症状。高 IRR 究竟是源于真正的投资技能,还是只是时机得当的风险承担?到目前为止,我们已经对谁在裸泳有所了解——也就是说,对谁属于后者而非前者有所了解。当潮水完全退去时,我们才会确切知晓。
为了帮助您考虑未来,我制定了上述观点的反面,即熊市的三个阶段:
-
-
-
This growth in buyout capital was spurred on by high reported IRRs, which in turn were facilitated by dividend recaps and quick flips, themselves a symptom of the increasingly overheated capital market environment. Had the high IRRs been the result of genuine investment skill or just well-timed risk taking? So far we’ve learned a little about who swam naked – that is, for whom it was the latter rather than the former. We’ll know for sure when the tide is fully out. To aid in your consideration of the future, I’ve formulated the converse of the above, the three stages of a bear market:
第一种情况,只有少数谨慎的投资者意识到,尽管眼下牛市当道,但形势不会一直美好;
第二种情况,大多数投资者都意识到情况在恶化;
第三种情况,所有人都坚信事情只会更糟。
the first, when just a few prudent investors recognize that, despite the prevailing bullishness, things won’t always be rosy, the second, when most investors recognize things are deteriorating, and the third, when everyone’s convinced things can only get worse.
可以肯定地说,我们已经深入这三个阶段中的第二个阶段了。坏消息和资产减记层出不穷,越来越多的人意识到了创新、杠杆、衍生品、交易对手风险以及按市价计值会计方法这些事物中固有的危险。而且,问题似乎越来越无解。
不过,总有一天我们会到达第三个阶段,人群将放弃寻找解决方案。除非金融世界真的就此终结,否则我们很可能会遇到一生难遇的投资机会。重大的底部往往出现在所有人都忘了潮水还会涨回来的时候。这正是我们为之而活的时刻。

Certainly we’re well into the second of these three stages. There’s been lots of bad news and writeoffs. More and more people recognize the dangers inherent in things like innovation, leverage, derivatives, counterparty risk and mark-to-market accounting. And increasingly the problems seem insolvable. One of these days, though, we’ll reach the third stage, and the herd will give up on there being a solution. And unless the financial world really does end, we’re likely to encounter the investment opportunities of a lifetime. Major bottoms occur when everyone forgets that the tide also comes in. Those are the times we live for. March 18, 2008
