市场知道些什么?

What Does the Market Know?

老友桑迪是名民航飞行员。有人问他怎么形容自己的工作,他的回答永远是那句:“漫长的无聊,间或夹杂着惊恐的时刻。”投资经理的日子有时也是这样,过去几周就属于后者。我们看到了坏消息,也看到价格一路狂泻。那些在股价跌 20% 前、油价还在 70 美元时认为价格合理而买入的投资者,如今在更低的价位上,反倒开始怀疑这些资产是不是风险太高了。

在周四那份题为“躺上沙发”的备忘录里,我提到最近被问得最多的两个问题:“中国经济的疲软对美国以及世界其他地区意味着什么?我们是否正走向一场堪比 2008 年规模的新危机?”周五早上,彭博社邀我上节目聊这份备忘录,主持人翻来覆去问的其实是第三个问题:“市场下跌让你担心吗?”于是就有了这份回应。

答案藏在一个问题里:“市场知道什么?”市场是聪明的吗——聪明到你应该唯它马首是瞻?还是愚蠢的——愚蠢到你应该对它置之不理?以下是我在 9 月那份“这并不容易”中写过、后来又收进“躺上沙发”里的话:

尤其是在下跌行情中,许多投资者给市场安上了智慧,指望它告诉自己正在发生什么、以及该怎么应对。这是你能犯的最大错误之一。正如本·格雷厄姆指出的,日复一日的市场并不是基本面分析师,它是投资者情绪的晴雨表。你不能太把它当回事。市场参与者对基本面真实状况的洞察相当有限,而他们买卖背后可能存在的任何理性,都被情绪的起伏搅得模糊不清。把最近全球市场的下跌解读为市场“知道”前方艰难岁月将至,这是错的。

这份备忘录剩下的部分都将围绕这个主题展开(如果你已经看够了,或者时间紧,看到这里就可以打住了)。

My buddy Sandy was an airline pilot. When asked to describe his job, he always answers, “hours of boredom punctuated by moments of terror.” The same can be true for investment managers, for whom the last few weeks have been an example of the latter. We’ve seen bad news and prices cascading downward. Investors who thought stocks were priced right 20% ago and oil $70 ago now wonder if they aren’t risky at their new reduced prices. In Thursday’s memo, “On the Couch,” I mentioned the two questions I’d been getting most often: “What are the implications for the U.S. and the rest of the world of China’s weakness, and are we moving toward a new crisis of the magnitude of what we saw in 2008?” Bloomberg invited me on the air Friday morning to discuss the memo, and the anchors mostly asked one version or another of a third question: “does the market’s decline worry you?” That prompted this memo in response. The answer lies in a question: “what does the market know?” Is the market smart, meaning you should take your lead from it? Or is it dumb, meaning you should ignore it? Here’s what I wrote in “It’s Not Easy” in September and included in “On the Couch”: Especially during downdrafts, many investors impute intelligence to the market and look to it to tell them what’s going on and what to do about it. This is one of the biggest mistakes you can make. As Ben Graham pointed out, the day-to-day market isn’t a fundamental analyst; it’s a barometer of investor sentiment. You just can’t take it too seriously. Market participants have limited insight into what’s really happening in terms of fundamentals, and any intelligence that could be behind their buys and sells is obscured by their emotional swings. It would be wrong to interpret the recent worldwide drop as meaning the market “knows” tough times lay ahead. The rest of this memo will be about fleshing out this theme (meaning you can stop reading here if you’ve had enough or are short on time).

共识意见的本质

我之所以提到本·格雷厄姆,是基于他那句名言:从长远看,市场是一台称重机,但从短期看,它是一台投票机。换句话说,长期而言,投资者的共识会搞清事物的真实价值,并把价格推向那里。但短期内,市场不过是在反映人们对某项资产未来受欢迎程度的共识意见,而这种意见极易受心理起落的影响。

那么,市场知道什么?首先必须明白,就这个目的而言,“市场”其实并不存在。市场里只有一群参与者。市场不过就是参与者的总和,它所“知道”的,也不会超出这些人的集体认知。

The Nature of Consensus Opinion I based the above reference to Ben Graham on his famous observation that in the long run the market’s a weighing machine, but in the short run it’s a voting machine. In other words, in the long term the consensus of investors figures out what things are really worth and moves the price there. But in the short term, the market merely reflects consensus opinion regarding an asset’s future popularity, something that’s highly susceptible to the ups and downs of psychology. So, what does the market know? First it’s important to understand for this purpose that there really isn’t such a thing as “the market.” There’s just a bunch of people who participate in a market. The market isn’t more than the sum of the participants, and it doesn’t “know” any more than their collective knowledge.

这一点非常重要。如果你相信市场拥有超越其参与者集体智慧的某种特殊洞察力,那你我和根本分歧就在所难免。群体的思考并不具备协同效应。在我看来,市场的投资智商并不高于参与者的平均智商。而且,在某一特定时点,每一位参与交易的人都在资产定价中投下了按成交量加权的一票。

能力水平参差不齐的人共同决定了价格。他们在知识、经验、洞察力和情绪化程度上千差万别。市场并不会因为某些人在这几方面更胜一筹就赋予他们更大的影响力,尤其是在短期内。我对这个问题的底线看法是:市场价格仅仅反映了市场参与者的平均洞察力。

这是第一点。

如果说有什么东西确实具有协同效应,我认为那是情绪。它会积聚成羊群行为或集体狂热。当一万人陷入恐慌时,情绪似乎会像滚雪球一样越滚越大。人们相互影响,情绪相互叠加,以至于市场整体的恐慌程度可能高于任何单个参与者在孤立状态下的恐慌。这一点我稍后再谈。

现在我们想想投资的第一目标:低买。我们要买的是那些价格低估了底层资产或盈利价值(价值投资),或低估了未来潜力(成长投资)的东西。无论哪种情况,我们都是在寻找市场犯错的机会。如果我们认为市场永远正确——即有效市场假说——我们就不会一辈子做主动投资者。既然我们选择了这条路,最好相信自己比共识懂得更多。所以,按定义来说,我们绝不能认为市场——也就是所有其他投资者的总和——无所不知,或者比我们懂得更多,或者永远正确。这是第二点。

这就顺理成章地引出第三点:为什么要听从一群比你懂得少的人指挥?在《沙发上的思考》一文中,我写道,这一切看起来显而易见:投资者很少能保持客观、理性、中立和稳定的立场。你同意还是不同意?市场是一位临床般理性的基本面分析师,还是投资者情绪的晴雨表?市场如今的行为,看起来像是成熟成年人该效仿的样子吗?

在我看来,这很清楚:市场并没有超乎寻常的洞察力,但它的情绪化程度往往超乎寻常。因此,我们不该听从它的指令。事实上,逆向投资正是建立在一个前提之上:我们通常应该反着人群来,尤其是在极端时刻。我更喜欢这种做法。

一个例证——2008 年崩盘

2008 年以我平生所见最大的恐慌告终。累积成这一结果的事件包括:

This is a very important point. If you believe the market has some special insight that exceeds the collective insight of its participants, then you and I have a fundamental disagreement. The thinking of the crowd isn’t synergistic. In my view, the investment IQ of the market isn’t any higher than the average IQ of the participants. And everyone who transacts gets a volume-weighted vote in setting an asset’s price at a given point in time. People of all different levels of ability act together to set the price. They vary all over the lot in terms of knowledge, experience, insight and emotionalism. The market doesn’t give the ones who are superior in these regards any more influence than the others, especially in the short run. My bottom line on this subject is that the market price merely reflects the average insight of the market participants. That’s point number one. If anything, I think it’s emotion that’s synergistic. It builds into herd behavior or mass hysteria. When 10,000 people panic, the emotion seems to snowball. People influence each other, and their emotions compound, so that the overall level of panic in the market can be higher than the panic of any participant in isolation. That’s something I’ll return to later. Now let’s think about the first goal of investing: to buy low. We want to buy things whose price underestimates the value of the underlying assets or earnings (value investing) or the future potential (growth investing). In either case, we’re looking for instances when the market is wrong. If we thought the market was always right – the efficient market hypothesis – we wouldn’t spend our lives as active investors. Since we do, we’d better believe we know more than the consensus. So by definition we must not think the market – that is, the sum of all other investors – knows everything, or knows more than we do, or is always right. That’s point number two. And that leads logically to point number three: why take instruction from a group of people who know less than you do? In “On the Couch,” I wrote that it all seems obvious: investors rarely maintain objective, rational, neutral and stable positions. Do you agree with that or not? Is the market a clinical and rational fundamental analyst, or a barometer of investor sentiment? Does the market’s behavior these days look like something a mature adult should emulate? It seems clear to me: the market does not have above average insight, but it often is above average in emotionality. Thus we shouldn’t follow its dictates. In fact, contrarianism is built on the premise that we generally should do the opposite of what the crowd is doing, especially at the extremes, and I prefer it. A Case in Point – The Crash of 2008 The year 2008 culminated in the greatest panic I’ve ever seen. The events that built up to it included:       

次贷危机中,大规模次级抵押贷款违约及抵押贷款支持工具的崩盘,导致投资于这些工具的基金遭受重创,尤其是贝尔斯登旗下两只基金的破产,进而引发贝尔斯登本身的崩溃,不得不由摩根大通几乎分文不取地收购。美国银行出手拯救美林,富国银行接管美联银行,摩根大通则收购了华盛顿互惠银行(此前该行已被储蓄机构监管局查封)。美国银行和巴克莱决定不收购雷曼兄弟,美国财政部也拒绝出手相救,最终雷曼兄弟申请破产。市场普遍担忧,摩根士丹利若无法筹集到额外资本,将成为下一个倒下的机构,同时,其他公司可能步其后尘的猜测也甚嚣尘上。

massive subprime mortgage defaults and the failure of mortgage backed vehicles, meltdowns at funds that had invested in those vehicles, notably two Bear Stearns funds, the collapse of Bear Stearns, necessitating its purchase by JPMorgan for almost no consideration, rescues of Merrill Lynch by Bank of America; Wachovia by Wells Fargo; and Washington Mutual by JPMorgan (after it was first seized by the Office of Thrift Supervision), decisions on the part of BofA and Barclays not to acquire Lehman Brothers, and on the part of the U.S. Treasury not to bail it out, leading to Lehman’s bankruptcy filing, the appearance that Morgan Stanley would be next if it couldn’t secure additional capital, and widespread speculation regarding other firms that might follow.

接下来便是一场大规模的螺旋式下坠。促成这一局面的因素包括:

A massive downward spiral ensued. Among the contributing factors were:  

银行股价格的断崖式下跌,

大规模做空银行股(早前的“提价规则”曾规定,股票只能以高于上一笔成交价的价格卖空,这意味着做空行为无法直接打压股价。但该规则于 2007 年被废止,自此股票做空不再受时间限制。于是,做空者可以肆意压低股价——无论是有意为之,就像 1920 年代所谓的“熊市突袭”,还是仅仅因为他们认为这些股票理应被卖出),

通过信用违约互换为银行债务投保的成本急剧上升。

precipitous declines in the prices of bank stocks, large-scale short selling of the stocks (the “uptick rule” previously mandated that a stock could only be sold short at a price above the last trade, meaning short selling couldn’t force the price down. But the rule was repealed in 2007, so there ceased to be limits on when stocks could be shorted. Thus short sellers could force stock prices down – whether intentionally, in what in the 1920s were called “bear raids,” or just because they thought the stocks were right to sell), dramatic increases in the cost to insure the debt of banks through credit default swaps.

在上述环境中,银行股的螺旋式下跌因以下因素而加剧(这些因素是否被蓄意操纵,我不敢断言):

In the environment described above, the downward spiral in bank stocks was intensified by the following factors (whether they were intentionally manipulated, I can’t say for sure):    

做空银行股很容易,只需卖空它们的股票就能压低股价。股价下跌被视为银行疲软的迹象,导致购买信用违约互换(CDS)保护的成本上升。而 CDS 保护成本的上升又被视为另一个负面信号,进一步压低股价。

It was easy to bet against the banks by buying credit default swaps (CDS) on their debt. It was easy to depress bank stocks by selling them short. The declining stock prices were taken as a sign that the banks were weakening, causing the cost of buying CDS protection to rise. The rising cost of CDS protection was taken as an additional negative sign, causing the stocks to fall further.

我可以告诉你,当时那种局面就像个停不下来的恶性循环,挡都挡不住。有人拿它跟《中国综合症》那部电影比:1979 年简·方达和迈克尔·道格拉斯主演的片子,讲核反应失控,眼看要把反应堆的部件从美国一路穿透地心,捅到中国去。恐慌之下,摩根士丹利的股价跌了 82%,只剩不到 10 美元。

不过有一点值得注意:上面说的这个负反馈循环,能一直转下去,靠的并不是银行实际经营出了什么状况,也未必跟它们内在价值的变化有多大关系。后来财政部出手,对 19 家被视为“系统重要性”金融机构的股票实施卖空限制。摩根士丹利从三菱日联金融集团拿到了 90 亿美元的可转换股权注资。恐慌这才平息。经济和资本市场也跟着恢复。一年后,摩根士丹利的股价又回到了 33 美元。

你是希望自己当年听了市场的话,2008 年把银行股给卖了?还是希望自己压根没理它,反而大买特买?说到底,市场到底懂不懂行?

答案有三种可能:

I can tell you, it had the feel of an unstoppable vicious circle. Some compared it to the “China Syndrome”: a 1979 movie with Jane Fonda and Michael Douglas in which an out-of-control nuclear reaction threatens to propel reactor components through the earth’s core, from the U.S. to China. Thus the stock of panic-ridden Morgan Stanley (for example) fell 82%, to less than $10. But it’s important to note that the negative feedback loop described above was able to continue without reference to – and not necessarily in reasonable relationship to – actual developments at the banks or changes in their intrinsic value. Eventually, however, the Treasury restricted short selling in the stocks of 19 financial institutions deemed “systemically important.” Morgan Stanley secured a $9 billion injection of convertible equity from Mitsubishi UFJ Financial Group. The panic subsided. The economy and capital markets recovered. And Morgan Stanley’s stock traded at $33 a year later. Do you wish you had taken the market’s instruction in 2008 and sold bank stocks? Or do you wish you had rejected its advice and bought instead? In short, did the market know anything? There are three possible answers:   

2008 年市场把摩根士丹利的股价压得那么低,是大错特错。

市场是对的;它恰当反映了可能发生却未发生的灾难性崩溃的可能性。

摩根士丹利在 2008 年的情况是市场判断错了,但大多数时候市场并没有错。

The market was flat wrong in 2008 when it took Morgan Stanley’s stock so low. The market was right; it properly reflected the possibility of a meltdown that could have happened but didn’t. The market was wrong in the case of Morgan Stanley in 2008, but most of the time it isn’t.

第一种说法我喜欢,第二种也有吸引力。但虽然崩溃确实有可能,低于 10 美元的定价或许赋予了这一可能性过高的权重。当然,第三种说法我并不信服。

I like the first, and the second is appealing as well. But while a meltdown certainly was possible, the below-$10 price probably assigned it too high a likelihood. And, of course, I’m not persuaded by the third.

一个典型案例——金融危机中的优先级贷款

说到 2008 年,我想回顾一下优先级贷款的表现。过去,银行发放公司贷款,有时会与几家关系好的银行组成银团分担一部分,但其余部分自己留着。后来惯例变了,银行把贷款广泛银团化,卖给各类买家,自己留得很少。这个过程与投资银行承销证券更相似,而不是商业银行过去的放贷流程。

优先级贷款成了像我们这样的信用投资者的重要活动领域。它们通常是发行人最优先级的债务,所以被认为信用风险很小。而且由于按浮动利率付息,也没有利率风险。(当然,风险这么小,收益率也低。)这是我这辈子经手过的最高质量的工具。

因为被认为非常安全,贷款被普遍视为适合杠杆投资,金融危机之前,大量高杠杆的贷款抵押债券(CLO)被设立来持有这些贷款。以低浮动利率借入资金、买入支付高浮动利率的优先级债务,极具吸引力,CLO 业务迅速膨胀。

优先级贷款受到 2008 年事件的剧烈冲击。由于优先级贷款被用来为收购融资,而收购价格是现金流的高倍数,投资者开始担心发行人的偿债能力,尤其是到期时再融资的能力(因为资本市场已经关闭)。贷款价格跌到了没有违约情况下从未见过的水平;过去非困境优先级贷款很少跌破 95,现在跌到 80 多,然后跌到 60 多。由于价格崩塌,“按市值计价”的 CLO 收到无法满足的追加保证金通知,银行没收投资组合,通过隔夜竞价(BWIC)交易清算。不分青红皂白的抛售进一步压低价格,引发更多追加保证金和更多 BWIC:又一个典型的负反馈循环。

优先级贷款指数 2008 年下跌 29%,超过高收益债券指数 25% 的跌幅。为什么优先级债务在危机中比次级债务跌得还多?答案是优先级贷款是杠杆买入的重灾区(因此也是追加保证金和强制抛售的重灾区),而高收益债券不是。

市场崩盘时,关键问题很少有人问:这些贷款值多少,会不会偿付?这取决于违约前景,但 2008 年底很少有人觉得自己能评估,或者有时间去评估。他们也没有追问价格崩塌在多大程度上是追加保证金和强制抛售造成的,而不是投资基本面造成的。他们只是屈服于悲观情绪,卖出离场。

2008 年结束,卖出、跌价、追加保证金、更多卖出、更多跌价的循环也随之结束,贷款价格不再下跌。然后它们开始上涨。优先级贷款指数 2009 年上涨 45%,意味着在 2007 年 12 月 31 日买入且没卖的人,到 2009 年 12 月 31 日总体上涨 3%。如果你听从市场的建议,在雷曼倒塌后的崩盘中跟着负面信号卖出呢?你确实可以抱怨,但怪谁呢?市场……还是你自己?

A Case in Point – Senior Loans in the Financial Crisis While on the subject of 2008, I want to review the performance of senior loans. In the old days, banks made corporate loans, sometimes sharing part with a syndicate of a few friendly banks but retaining the rest. More recently the custom changed, with banks syndicating their loans widely to buyers of all types and retaining rather little. This process has more in common with investment banks’ underwriting of securities than with the commercial banks’ prior lending process. Senior loans became a significant area of activity for credit investors like us. They’re typically their issuers’ senior-most debt, so they’re perceived to carry little credit risk. And since they pay interest at floating rates, there is no interest rate risk. (Of course, with so little risk, they offer low yields.) They’re the highest-quality instruments I’ve ever dealt in. Because they were considered so safe, loans were widely deemed appropriate for levered investment, and prior to the financial crisis large numbers of highly levered Collateralized Loan Obligations, or CLOs, were formed to hold them. Borrowing at low floating rates to buy senior debt paying high floating rates was very enticing, and the CLO business mushroomed. Senior loans were affected dramatically by the events of 2008. Since senior loans had been used to fund buyouts with purchase prices at high multiples of cash flow, investors became concerned about the issuers’ ability to service them, and especially to refinance them when they came due (since the capital markets had slammed shut). Loan prices fell to levels never seen before in the absence of a default; whereas non-distressed senior loans had rarely sold below 95 in the past, now they fell to the 80s, and then to the 60s. Because of the collapsing prices, “market-value” CLOs received margin calls they couldn’t meet, and banks seized portfolios and liquidated them in overnight BWIC (bid-wanted-incompetition) transactions. The indiscriminate selling put further pressure on prices, leading to more margin calls and more BWICs: another prototypical negative feedback loop. The senior loan index was down 29% in 2008. That exceeded the 25% decline of the high yield bond index. Why would senior debt fall more during a crisis than junior debt? The answer is that senior loans had been ground zero for buying with leverage (and thus for margin calls and forced selling) whereas high yield bonds had not. The key questions were rarely asked while things melted down: what were the loans worth, and would they pay? That depended on the outlook for defaults, but in late 2008 few people felt they could assess it or could take the time required to do so. And neither did they question the extent to which the price collapses had been caused by margin calls and forced selling, rather than investment fundamentals. They just succumbed to negativity and sold. When 2008 ended, and with it the cycle of selling, price declines, margin calls, more selling and more price declines, the prices of loans stopped going down. And then they went up. The senior loan index rose 45% in 2009, meaning someone who invested on December 31, 2007 and didn’t sell was up 3% overall by December 31, 2009. What if you had taken the market’s advice in the post-Lehman meltdown and sold in response to the negative signal? You’d have a valid complaint, but whom would you blame? The market . . . or yourself?

市场下跌说明了什么价值问题?

大幅度的价格下跌意味着什么?它们意味着市场参与者察觉到了基本面恶化。但价格下跌所传递的信息是反映性的,而非预测性的。它们告诉你已经发生的事件,以及投资者对这些事件的反应。关于未来事件,它们并不比普通投资者所知的更多。而且,我再次坚信:(一)普通投资者所知甚少;(二)追随普通观点无助于你取得超越平均的表现。

我的大多数读者希望表现得比普通投资者更好。正如我在《敢于伟大 II》(2014 年 4 月)以及我的著作《最重要的事》中关于“第二层思维”的讨论中所阐述的,要做到这一点,你必须以不同于普通投资者的方式投资。要做到这一点,你必须以不同于普通投资者的方式思考。而要做到这一点,你必须考虑不同于普通投资者所考虑的投入,或以不同的方式考虑这些投入。你根本无法追随他们行为所发出的信号。

这是一个逻辑问题:如果价格变动反映的是普通观点,那么追随它们所谓的建议,就无法帮助你获得超越平均的表现。

现在让我们思考是否应该卖出这个问题。以下是一些可能卖出的理由:

What Does a Falling Market Say About Value? What do big price declines mean? They mean market participants sense fundamental deterioration. But what price declines say is reflective, not predictive. They tell you about the events that have occurred, and how investors have reacted to them. They don’t tell you anything that the average investor doesn’t know about future events. And, again, I’m firmly convinced (a) the average investor doesn’t know much, and (b) following average opinion won’t help you attain above average results. Most of my readers want to perform better than the average investor. As I’ve set out in “Dare to Be Great II” (April 2014) and in the discussion of “second level thinking” in my book The Most Important Thing, to accomplish that, you have to invest differently than the average investor. To do that, you have to think differently than the average investor. And to do that, you have to consider different inputs than the average investor, or consider inputs differently. You simply can’t follow the signals their behavior provides. It’s a matter of logic: if price movements reflect average opinion, following their supposed advice can’t help you perform above average. Now let’s think about the question of whether to sell. Here are some possible reasons to do so:   

认为价格相对于基本面偏高。

认为当前价格与当前基本面相比或许并不高,但基本面将以价格未预见的方式恶化。(换言之,价格相对于基本面未来将被如何看待而言偏高。)

认为无论基本面如何,价格都会下跌,也就是说今天卖出可以避免损失,或为自己将来低价买入获利创造条件。

Belief that the price is high relative to the fundamentals. Belief that while the current price may not be high relative to the current fundamentals, the fundamentals will deteriorate in ways that aren’t anticipated by the price. (In other words, the price is high relative to how the fundamentals will come to be viewed.) Belief that the price will fall regardless of the fundamentals, meaning that by selling today you can avert a loss and/or position yourself to profit by buying lower later.

您是否认同以上是卖出的主要原因?还有没有其他原因?这些理由是否都站得住脚?

在我看来,前两条最有说服力。这正是娴熟投资者思考的内容。这两项决定都围绕一个叫作“内在价值”的概念展开。投资只有一种明智的形态:弄清楚某样东西值多少钱,再看能否以等于或低于这个价格买入。一切皆关乎价值。

但请注意,上面列出的第三个卖出理由与价值毫无关系。无论是相对于当前基本面,还是相对于市场对未来基本面的预期,价格都可能偏高、偏低或合理。您卖出仅仅是因为认为价格会下跌。

首先,如果价格相对于基本面偏低,仅仅因为担心短期可能下跌就卖出,这合理吗?长期价值投资者在价格相对价值偏低时会持有或买入。价格低于价值正是他的梦想。为什么仅仅因为认为某资产会跌一阵子就卖出低价资产?多数人都理解“两重决策股票”的难处:您因为认为价格可能下跌而卖出(尽管这可能是您想长期持有的标的),然后还得琢磨何时买回来。去年查理·芒格向我抱怨,这其实是“三重决策股票”:您因为认为价格已到位而卖出,得琢磨何时买回来,在此期间还得为手里的钱找别的去处。以我的经验,大多数人有幸在下跌前卖出后,忙着拍手自夸,就忘了买回来。

Do you agree that these are the main reasons to sell? Are there others? Are these all legitimate? For me the first two are compelling. This is what the skilled investor thinks about. Both of these decisions are made relative to something called “intrinsic value.” There’s only one intelligent form of investing: figure out what something's worth and see if you can buy it at or below that price. It’s all about value. But note that the third reason to sell shown above has nothing to do with value. The price may be high, low or fair relative to the fundamentals today or what they’re expected to be tomorrow. You just sell because you think the price will fall. First, does it make sense to sell something if the price is low relative to the fundamentals, just because you fear it may fall in the short run? A long-term value investor holds or buys when price is low relative to value. Low price relative to value is his dream. Why sell a low-priced asset just because you think it’s going to fall for a while? Most people understand the challenge in dealing with “twodecision stocks”: you sell because you think the price may fall (even though it may be something you’d like to hold for the long term), and then you have to figure out when to buy it back. Last year Charlie Munger complained to me that they’re really “three-decision stocks”: you sell it because you think the price is full, you have to figure out when to buy it back, and in the meantime you have to come up with something else to do with your money. In my experience, most people who are lucky enough to sell something before it goes down get so busy patting themselves on the back that they forget to buy it back.

假设其他条件不变,当某样东西降价时,你应该更想拥有它,而不是更不想。买入并持有的价值投资者立场坚定,无视价格波动。更进一步的是逆向投资者,他们与市场背道而驰,在价格下跌时买入,在价格上涨时卖出。

其次,如果并非基于基本面,那么对于上面列出的第三个卖出理由,人们该如何做出决定呢?本质上,资产价格变动源于两点:前景的变化(宏观层面或针对特定资产)以及对资产态度的变化。换言之,就是基本面和估值。基本面已在上面讨论过。如果你想从与基本面变化无关的价格变动中获利,那你就得预测投资者心理。如果《沙发上的心理医生》没能说服你认为这不可能,这份备忘录大概也做不到。我的底线是,市场并非每天都在评估内在价值,而且危机时期它们肯定也做不好这件事。因此,市场价格波动并不能说明多少基本面问题。即便在最好的时期,当投资者由基本面而非心理驱动时,市场所显示的也只是参与者认为的价值,而非真实的价值。价值这东西,市场并不比普通投资者知道得更多。而普通投资者的建议显然无法帮你成为高于平均水平的投资者。

All other things being equal, as something falls in price, you should want to own it more, not less. The buy-and-hold value investor is stalwart, ignoring price fluctuations. Even better, the contrarian moves opposite to the market, buying when the price falls and selling when it rises. Second, if not on the basis of fundamentals, how does one make the decision to sell for the third reason listed above? Essentially, two things give rise to changes in asset prices: changes in the outlook (macro or asset-specific) and changes in attitudes toward the asset. In other words, fundamentals and valuation. Fundamentals are dealt with above. If you’re going to try to benefit from changes in price that are unrelated to changes in fundamentals, you’re left having to predict investor psychology. If “On the Couch” wasn’t successful in convincing you this isn’t possible, this memo probably won’t be, either. My bottom line is that markets don’t assess intrinsic value from day to day, and certainly they don’t do a good job during crises. Thus market price movements don’t say much about fundamentals. Even in the best of times, when investors are driven by fundamentals rather than psychology, markets show what the participants think value is, rather than what value really is. Value is something the market doesn’t know any more about than the average investor. And advice from the average investor obviously can’t help you be an above average investor.

市场下跌说明了怎样的心理?基本面——对经济、公司或资产的前景——并不会日复一日地发生多大变化。因此,日常的价格变动主要反映的是(a)市场心理的变化,从而(b)谁想持有某物或谁想抛售某物的变化。日价格波动越剧烈,这两点就越成立。大幅波动说明心理正在发生根本性转变。

而且,正如我在第二页所说,情绪波动——市场情绪或心理的摇摆——确实具有协同效应。也就是说,在群体心理中,2 + 2 = 5。虽然我不认为资产价格体现的智慧会超过其市场参与者平均所拥有的智慧,但我确实相信,群体心理会使整体摆动到比个体单独时更极端的情感水平。简而言之,人们会互相“传染”疯狂。而当形势不佳时——比如现在——他们又会互相拖累。这也是我们不良债务团队在 2008 年占据优势的一个因素:他们能在市场低谷时买入,因为他们不在纽约,那里每个人都在传播恐怖故事、互相打击士气。

我们再次可以通过逻辑获得洞见。我们都知道,我们希望在低点买入(而不是卖出),在高点卖出(而不是买入)。那么,因为下跌而卖出,或因为上涨而买入,又怎么可能正确呢?主张后一种做法的人必然认为(a)下跌和上涨的趋势往往会延续而非反转,并且/或者(b)他们能分辨出哪些下跌意味着“买入时机”、哪些意味着“卖出时机”。也许有些智者具备后一种能力,但这样的人不多。总的来说,我认为因为某物下跌就卖掉它(就像因为某物上涨就买入它一样)是荒谬的。

随着价格下跌,确实存在一些真实的卖出理由:

What Does a Falling Market Say About Psychology? Fundamentals – the outlook for an economy, company or asset – don’t change much from day to day. As a result, daily price changes are mostly about (a) changes in market psychology and thus (b) changes in who wants to own something or un-own something. These two statements become increasingly valid the more daily prices fluctuate. Big fluctuations show that psychology is changing radically. And, I said on page two, emotional fluctuations – swings in market sentiment or psychology – do seem to be synergistic. That is, in crowd psychology, 2 + 2 = 5. While I don’t think the price of an asset reflects more wisdom than is possessed by the average of its market’s members, I do believe mass psychology will make a group swing to reach greater emotional extremes than its members would separately. In short, people make each other crazy. And when times are bad – like now – they depress each other. That was a factor in the edge enjoyed by our distressed debt team in 2008: they were able to buy at the market’s lows because they weren’t in New York, where everyone was trading scary stories and getting each other down. Again, we can gain insight through logic. We all know we want to buy (not sell) at the lows, and sell (not buy) at the highs. So then how can it be right to sell because of a decline or buy because of a rise? Advocates of this latter approach must think (a) declines and rises tend to continue more than they reverse and/or (b) they can tell which declines mean “buy” and which mean “sell.” Some savants may have that latter ability, but not many. In general, I think it’s ridiculous to sell something because it’s down (just as it is to buy because it’s up). As prices fall, there are some very genuine reasons to sell:   

有些人因恐惧加剧而不得不减仓,以求心安。

有些人损失惨重,卖出是为了确保不会遭遇无法承受的亏损。

还有些人必须卖出,以偿还苛刻的债权人或满足投资者的赎回要求。

Some people feel rising fear and have to lighten their positions in order to retain their composure. Some, having lost a lot of money, sell to be sure they won’t experience losses they can’t survive. Some have to sell to repay demanding creditors or satisfy investor withdrawals.

这些理由并非“站不住脚”。只不过,其中没有一条与赚钱有关。

These reasons are not “invalid.” It’s just that none of them has anything to do with making money.

大多数成熟的投资者在理智上都清楚,短期价格波动在基本面意义上无足轻重,最佳的回报来自长期持有、安然度过波动。但有时人们还是会卖掉,或许就是出于上述那些原因。这么做有可能把一次短期波动变成永久性的损失,因为会错失随后的复苏。我认为这是投资中的大忌。

Most mature investors know intellectually that short-term price fluctuations are low in fundamental significance, and that the best results will be achieved if they hold on to their positions and ride out the volatility. But sometimes people sell anyway, perhaps for the above reasons. Doing so has the potential to convert a short-term fluctuation into a permanent loss by causing any subsequent recovery to be missed. I consider this the cardinal sin in investing.

媒体知道什么?

我通常能从报刊或广播电视媒体里找到能佐证我观点的内容。以下是《纽约时报》周六商业版的头条:

市场抛售或预示美国经济放缓,担忧情绪升温

或许是时候让大家重新认真对待市场了。

随着新年头几个交易日股价开始下跌,许多华尔街专业人士倾向于将跌幅形容为市场近年来在走高之前经历过的那种调整。

但本周抛售加剧,这种观点烟消云散。人们越来越担心,市场正在发出信号:美国经济尽管近期不乏亮点,却已处于放缓的边缘。

令人忧虑的是,中国的经济问题已在全球引发负面连锁反应,最终可能拖累美国家庭和企业。

所以,根本问题很简单:市场反映的是人们已知的信息,还是人们应该依据市场所知来行事?如果是后者,那么“市场”的信息又从何而来,难道不是来自人吗?对我来说答案很简单:如果人们听从市场的指令,他们其实是在听从……他们自己!

我在本备忘录开头设了个陷阱,现在就来揭晓。第一段我写道:“我们看到了坏消息和价格一路下跌。”你大概一扫而过。但这话当真成立吗?撇开中国和市场波动不谈,我们真的在总体上一直看到负面消息吗?会不会只是人们盯着坏消息不放,无视好消息,并且倾向于往坏处解读一切?

心理在一定方式上可以变得“真实”,反过来影响基本面。其中一种是资产价格下跌产生负面的“财富效应”,让人觉得自己变穷了,从而减少消费和投资。还有其他途径。但尽管市场下跌存在这种反馈影响,我仍然要说,美国和欧洲的经济基本面总体上并不消极。

周五,在下跌行情中,我参加了一场小型午餐会,在座的有投资专业人士,以及现任和前任政府经济与金融领域的高级官员。细节我就不赘述了:会上充斥着“一方面”和“另一方面”的权衡之词,但没有人认为今年会出现衰退。既然如此,那些制造价格信号、让别人觉得值得重视的又是些什么人?

What Do the Media Know? I’m usually able to find something in the print or broadcast media that helps me make my point. Here’s how The New York Times led the business section on Saturday: Concern Grows That Market Sell-off is an Early Warning of a U.S. Slowdown It may be time for everyone to take the markets seriously again. As stock prices started tumbling in the first trading days of the year, many Wall Street professionals were tempted to describe the declines as the sort of adjustment that the market has gone through in recent years before moving higher. But that opinion evaporated this week as the selling intensified. Concerns are now growing that the markets are signaling that the United States economy, despite its recent bright spots, is on the verge of a slowdown. The fear is that economic problems in China have set off negative reactions around the world that could ultimately weigh on American households and corporations. So the bottom-line question is simple: does the market reflect what people know, or should people base their actions on what the market knows? And if the latter, where does “the market” get its information, other than from people? For me it’s simple: if people follow the market’s dictates, they’re taking advice from . . . themselves! I set a trap at the beginning of this memo, and I want to spring it now. In the first paragraph, I wrote, “We’ve seen bad news and prices cascading downward.” You probably glossed over it. But is it true? Leaving aside China and the markets’ gyrations, have we really been seeing negative news on balance? Isn’t it just that people are fixating on bad news, ignoring good news, and tending to interpret things negatively? There are ways in which psychology can become “real,” feeding back to influence fundamentals. One is that declining asset prices produce a negative “wealth effect,” making people feel poorer and causing them to spend and invest less. And there are others. But despite the feedback influences of the market declines, I still would say U.S. and European economic fundamentals aren’t negative on balance. On Friday, in the midst of the declines, I participated in a small lunch attended by investment professionals and current and former senior government economic and financial leaders. I’ll spare you the details: there was a lot of “on one hand” and “on the other hand,” but no one thought there would be a recession this year. So then who are the people creating price signals to which others should accord significance?

我想在最后把一件事说得明明白白。我并不是说市场在价格下跌(或上涨)时从不正确。我只是说市场没有独特的洞察力,也不会传递任何始终有用的信息。它不是永远犯错,而是没有理由假定它是对的。

有些投资者的目标是,在后续走势向下时逢高卖出,而在后续走势向上时“逢低买入”。如果你认为光看市场本身的走势就能分辨出哪种情况是哪一种,那我们——再次——存在根本分歧。未来的价格走势只能根据价格与基本面之间的关系来预测。而鉴于市场的短期波动性和非理性,这种预测只能从长期角度来做。市场在这个问题上提供不了任何有用的东西。

I want to end by making one thing completely clear. I’m not saying the market is never right when prices go down (or up). I’m merely saying the market has no special insight and conveys no consistently helpful message. It’s not that it’s always wrong; it’s that there’s no reason to presume it’s right. It is the goal of some investors to sell on declines when the subsequent movements will be down, but “buy the dips” when the subsequent movements will be up. If you think you can tell which is which from watching the market movements themselves, then we – again – have a fundamental disagreement. Future price movements can only be predicted on the basis of the relationship between price and fundamentals. And, given the market’s short-term volatility and irrationality, this can only be done in the long-term sense. The market has nothing useful to contribute on this subject.
