似曾相识,往事重演。
Déjà Vu All Over Again
历史有什么用?毕竟,它已经是过去的事了。
事实是,历史可以成为我们最大的助力之一……在投资中如此,在生活中亦然。进入我投资生涯的第五个十年,我觉得自己创造附加值的能力,很大程度上来自我亲眼见证过的历史总量,以及我从中所提炼出的意义。
常读我备忘录的人都知道,我经常引用经受过时间考验的语录。为什么不呢?它们能流传下来,恰恰是因为它们切中要害、表达精妙。何必多此一举、重新发明轮子,改写这些文字,结果却远不如原文?在这个主题上,有几句话格外突出。我以前都用过,有的还不止一次:
忘记过去的人,注定要重蹈覆辙。(乔治·桑塔亚那)
你能回望得越远,就越有可能看得更远。(温斯顿·丘吉尔)
历史不会重演,但总会惊人地相似。(马克·吐温)
助长……狂热的还有两个因素,在我们这个时代或过去时代都很少被注意到。第一个是金融记忆的极度短暂。结果是,金融灾难很快被遗忘。再一个结果是,当相同或高度相似的情形再次出现时……它们被新一代——往往是年轻的、且总是极度自信的一代——欢呼为光辉的创新发现……在人类努力的领域中,很少有哪个领域像金融界这样,历史几乎无足轻重。过去的经验,即便还残留在记忆里,也被斥为原始的避难所,是那些缺乏洞察力、欣赏不了当下令人惊叹之奇迹的人才会依赖的东西。(约翰·肯尼斯·加尔布雷思)
人类与动物之间最大的区别之一,据说在于我们能够不通过直接经验而学习。我们不必坐在热炉子上才知道不能这么做。我们可以从历史和前人传递下来的教训中学习——这些教训是他们亲身经历或从别人那里学来的——这样我们就不必自己去体验。但要享受这种益处,我们必须关注那些走在我们前面的人和事。
正如马克·吐温所说,历史事件不会精确地重演。很少是同样的事情一遍遍地重复。以投资为例,波动的持续时间和幅度很少在每个周期之间完全相同。(当有人说“高收益债券往往在发行两周年左右违约”时,我简直要疯了。那只是某一特定时期的平均值,但没有理由非得如此,因此也没有理由让它成为一条对未来有用的规则。)
What good is history? After all, it‟s in the past. The truth is, history can be one of our greatest aids . . . in investing as in life. Here in the fifth decade of my investment career, I feel a lot of my ability to add value comes from the amount of history I‟ve witnessed and the significance I‟ve extracted from it. Regular readers know I often include time-tested quotations in my memos. Why wouldn‟t I? They‟ve endured precisely because they‟re so relevant and so well put. Why try to reinvent the wheel, rewriting them, only to come up short? On this subject, several stand out. I‟ve used them all before, some more than once: Those who cannot remember the past are condemned to repeat it. (George Santayana) The farther back you can look, the farther forward you are likely to see. (Winston Churchill) History doesn‟t repeat itself, but it does rhyme. (Mark Twain) Contributing to . . . euphoria are two further factors little noted in our time or in past times. The first is the extreme brevity of the financial memory. In consequence, financial disaster is quickly forgotten. In further consequence, when the same or closely similar circumstances occur again . . . they are hailed by a new, often youthful, and always supremely self-confident generation as a brilliantly innovative discovery . . . . There can be few fields of human endeavor in which history counts for so little as in the world of finance. Past experience, to the extent that it is part of memory at all, is dismissed as the primitive refuge of those who do not have insight to appreciate the incredible wonders of the present. (John Kenneth Galbraith) One of the greatest differences between humans and animals is supposed to lie in the fact that we can learn other than through direct experience. We don‟t have to sit on a hot stove to learn not to do it. We can learn from history and from lessons passed on by our predecessors – things they experienced or learned from others in turn – so that we needn‟t experience them ourselves. But to enjoy this benefit, we must pay heed to the people and events that preceded us. As Twain said, the events of history don‟t repeat exactly. It‟s rarely the very same thing over and over. In investing, for example, the duration and amplitude of fluctuations are rarely the same from cycle to cycle. (It drives me crazy when people say, “high yield bonds tend to default around the second anniversary of their issuance.” That happened to be the average for one particular period, but there‟s no reason for it to be true, and thus no reason it should be a useful rule going forward.)

但正如马克·吐温所说,有些主题会押韵。我称之为“倾向”或“行为模式”的,正是那些蕴含重要教训的东西。投资者忽视或遗忘过去的倾向值得注意,他们屈从于情绪、轻信夸大其词(但可能有利可图)的故事的习惯也是如此。尤其是,人们倾向于忘记事物的周期性,将过去趋势过度外推,并忽视均值回归的可能性。
科技泡沫可能不会很快重演。可能再也不会有线上杂货商以 200 倍营收的估值出售。可能再也不会有 CDO 平方或 SIV。这些都不是要紧的事。但肯定会有另一个周期、另一个泡沫和另一场危机。会有另一个时刻,人们因为某个激动人心的投资理念未来看似无限而过度支付,然后迎来幻灭和价格崩盘。会有另一个阶段,杠杆被过度追捧,随后,相应地,杠杆让人损失惨重的阶段。而且肯定会有另一个时刻,人们只想象收益的可能性,然后,在巨额亏损之后,他们只想到进一步的下跌。
这类事情就是押韵的。如果我们保持警惕,就能预见并识别它们,从而避免它们如此可靠地带来的损失和机会成本。
But as Twain also said, there are themes that rhyme. It‟s what I would call “tendencies” or “behavioral patterns” that present the important lessons. The tendency of investors to overlook or forget the past is noteworthy. So is their habit of succumbing to emotion and swallowing tall (but potentially lucrative) tales. In particular, people tend to forget the cyclical nature of things, extrapolate past trends to excess, and ignore the likelihood of regression to the mean. The tech bubble may not recur anytime soon. No online grocer may ever again sell at 200 times revenues. There may never be another CDO-squared or SIV. Those aren‟t the things that matter. But there’s sure to be another cycle, another bubble and another crisis. There’ll be another time when people overpay for exciting investment ideas because their future appears limitless, and then a time of disillusionment and price collapse. There’ll be another period when leverage is embraced to excess, and then, consequently, a period when it gets people killed. And there’ll certainly be another time when people can only imagine the possibility of gain, and then one when – after huge sums have been lost – they can think only of further declines. These are the kinds of things that rhyme. If we stay alert, we can anticipate and recognize them and thus avoid the losses and opportunity costs they bring so reliably.
股权的消亡
我撰写备忘录的灵感,有时来自长期观察的日积月累,有时则源于单次灵光一闪。这次属于后者。11 号那个周日,我在南美出差,躺在床上辗转难眠,便从奥克特里克的包里翻出点东西来读。我找到一份 1979 年 8 月 13 日《商业周刊》上“股权的消亡”一文的翻印件。我之前与里弗莱特资本的乔什·昆茨共进午餐时提到过这篇文章,他好意应我请求寄了过来。时隔 33 年我首次通读全文,妻子南希的战斗口号响在耳边:“这值得写一篇备忘录。”
这是一篇开创性的文章,预示着投资领域的巨变。其主旨如下:
自 1970 年以来,已有 700 万股民撤离股市。
劳工部对 ERISA 的解释是,允许机构投资者将养老金资金投向超越上市股票和高等级债券的领域,进入“小公司股票、房地产、商品期货,以及黄金和钻石”。于是,他们“大举涌入……抵押贷款支持证券、外国证券、风险投资、租赁、担保保险合同、指数化债券、股票期权和期货。”
“股票曾占共同基金资产的 80%,如今这一数字已跌至不足 50%。”
“几乎找不到公司愿意为自己的股票寻找买家。”
所有这一切,都是十三年高速通胀和十年平均年回报率不足 3% 的股市所带来的结果。
“劳工部的裁决,不过是过去十年股市遭遇的无穷无尽的不利事件中又添一桩。”
“这种‘股权的消亡’,不能再被视为一场股市反弹——无论多么强劲——所能遏制的。”
“因此,无论好坏,美国经济恐怕不得不将股权的消亡视为一种近乎永久的状态——有朝一日可能逆转,但绝非近期。”
The Death of Equities Sometimes the ideas for my memos come from the gradual accretion of insights over a long period of time, and sometimes they come from a single inspiration. This time it‟s the latter. Lying in bed sleepless on Sunday the 11th, while on a business trip to South America, I dug into my Oaktree bag for something to read. I came across a reprint of “The Death of Equities” from BusinessWeek magazine of August 13, 1979. I‟d spoken about it over lunch with Josh Kuntz of Rivulet Capital, and he was good enough to send it to me at my request. As I read it thoroughly for the first time in 33 years, my wife Nancy‟s battle cry rang out: “This calls for a memo.” This was a seminal article, signaling a tectonic shift in investing. Here was its thrust: Seven million shareholders have defected from the stock market since 1970. The Labor Department has interpreted ERISA as giving institutions that invest pension money the ability to go beyond listed stocks and high grade bonds and into “shares of small companies, real estate, commodity futures and into gold and diamonds.” Thus they were “pouring money into . . . mortgage-backed paper, foreign securities, venture capital, leases, guaranteed insurance contracts, indexed bonds, stock options, and futures.” “Whereas stocks once made up 80% of mutual fund assets, today that figure has slumped to less than 50%.” “Few corporations can find buyers for their stocks.” All of these things were the result of thirteen years of rapid inflation and ten years of returns on equities averaging less than 3% per year. “The Labor Department ruling is just one more in a nearly endless string of unhealthy things that have happened to the stock market over the past decade.” “This „death of equity‟ can no longer be seen as something a stock market rally – however strong – will check.” “For better or for worse, then, the U.S. economy probably has to regard the death of equities as [a] near-permanent condition – reversible some day, but not soon.”

据《商业周刊》当时所言,股票市场已大势已去,再不会有人愿意买进。
无论根源何在,通胀的制度化——加之通信与心理层面的结构性变迁——已使美国股市对数百万投资者失去了吸引力。
多么消极的一篇文章,俨然是整个市场的丧钟。它所标志的转折是什么?就是这一点:股票市场迷失的十年宣告终结,历史上最壮观的牛市由此启幕。
那篇杂志文章里蕴含的备忘录,足以写上一辈子,但我花的时间会少一些,用来剖析它。希望这些评论对你有用。
According to BusinessWeek, then, it was all over for equities. No one would ever buy them again. Whatever caused it, the institutionalization of inflation – along with structural changes in communications and psychology – have killed the U.S. equity market for millions of investors. What a negative article, ostensibly the death knell for an entire market. What was the shift that it marked? Simply this: the end of a lost decade for equities and the beginning of the greatest bull market in history. There‟s literally a lifetime of memos in that one magazine article, but I‟ll spend a little less than that dissecting it. I hope you‟ll find these comments useful.
瑜伽士的生平
劳伦斯“瑜伽士”贝拉是位棒球捕手,也是二十世纪中叶纽约扬基队成功王朝的中流砥柱。他球技出众,但同时也是措辞扭曲或误用词语的无可争议之王。举几个例子:
“不到结束,就不算结束。”
“比赛九成靠的是半吊子的心理。”
“走到岔路口时,就走过去。”
“常去别人的葬礼,否则他们不会来你的。”
事实上,瑜伽士为这份备忘录提供了标题,他说“这又是一次昨日重现。”然而,他为自己辩护时,否认了他闻名遐迩的这种倾向,说道:“我确实没说过我说的那些话。”
人们真会说这样的话吗?还是只有瑜伽士会?嗯,《股票之死》的作者可是给他添了不少竞争:
…随着房价不断攀升 …土地是对冲亏损的法宝。
少数我能确定的事情之一就是,没有价格会“不断攀升”。
个人 …正涌入货币市场基金,以求锁定高利率。
在货币市场基金里,你锁定利率的期限只以天计算。事实上,持有短期票据的最大缺点就是无法锁定收益率。我见过的最大错误之一,发生在 1981 年人们以 16% 的利率投资一年期存单,而非选择利率略低的多年期存单。
对投资者来说 …股价低迷依然是买入的阻碍。
作者的意思是,低价格反映出股票在此之前表现多糟,从而让投资者不愿入市。这完全不合逻辑,但在投资界,我们每天都能听到类似的话:
Yogi Lives Lawrence “Yogi” Berra was a baseball catcher and an integral part of the New York Yankees‟ successful dynasty in the middle of the twentieth century. While a great player, he was also the undisputed king of the tortured phrase or malapropism. Here are a few: “It ain‟t over ‟til it‟s over.” “Ninety percent of the game is half mental.” “When you come to a fork in the road, take it.” “Always go to other people‟s funerals, otherwise they won‟t go to yours.” In fact, Yogi supplied the title for this memo, saying “It‟s déjà vu all over again.” Rising to his own defense, however, he denied the tendency for which he is so well known, saying, “I really didn‟t say everything I said.” Do people really say things like these? Or was it just Yogi? Well, the writer of “The Death of Equities” gave him stiff competition: . . . with ever-escalating real estate prices . . . land is a hedge against loss. One of the few things I‟m sure of is that no price will be “ever-escalating.” Individuals . . . are flocking into money market funds to nail down high rates. In a money-market fund, the period for which you nail down a rate of interest is measured in just days. In fact, the prime drawback of holding short-term paper is its failure to lock in a yield. One of the biggest mistakes I‟ve witnessed took place when people invested in one-year certificates of deposit in 1981 at 16%, rather than multi-year CDs at rates a little lower. For investors . . . low stock prices remain a disincentive to buy. What the writer is saying is that low prices point up how badly stocks have done over the preceding period and thus discourage investors from participating in the market. This is totally illogical, but in the investment world we hear things like it every day:

“谁都知道 XYZ 股价偏低。”要是人人都知道它偏低,怎么没人买入把它推上去呢?
“ABC 没人敢碰,风险太大。”要是他们知道风险大——多半是因为价格太高——于是避之不及或抛售,那价格怎么还没跌到安全的水平呢?
作者接着写道:
事实上,现在平均股价大约是重置成本的 60%……
……公司趁股价低迷,掀起了史上最大的并购狂潮……
……按这个价格买入,比新建还便宜。
这位作者要是当年能看出其中的门道——股价低于资产价值,公司正因此互相收购——今天看起来就聪明多了。可他没看出来。他也没问一句:公司收购别的公司股票是精明之举,投资者买同样的股票怎么就不合理了?(顺带一提,正是能在股市上以比新建更便宜的价格买到公司,才让 KKR、安佰深和华平投资这些杠杆收购先驱在 1970 年代赚得盆满钵满。)
还得再牛个几年,才能引来大批投资者入场,重新点燃信心。
这句让我想起我最爱的一句约吉语录:“那家馆子没人去了,人太多。”等等,没人去,怎么还会人多?
同样,按这位作者的说法,得靠牛市才能吸引投资者的兴趣和信心。听起来有道理。可投资者的兴趣和信心,不正是牛市的前提吗?没这个,牛市怎么起步?
答案是:价格低到一定程度,股票不用等什么正式牛市自己就能涨起来。反过来,价格高到一定程度,股票也会自己把自己压垮。
结论很简单,我深信不疑:常识这东西并不常见。大众在极端时刻总是错的。投资的世界里,凡是直觉上显而易见的都值得怀疑,凡是真正要紧的都反直觉。而投资者一次又一次证明,他们比约基还不讲逻辑。
“Everyone knows XYZ is underpriced.” If everyone knows it‟s underpriced, why haven‟t they bought it and forced up its price? “Nobody will touch ABC; it‟s too risky.” If they know it‟s risky – presumably because its price is too high – and are shunning it or selling, why hasn‟t its price settled down to a level where it‟s safe? The writer continued: Indeed, the average stock price is now about 60% of the replacement value of the underlying assets . . . . . . companies have jumped on low stock prices to set off the biggest takeover binge in history . . . . . . buying at these prices is cheaper than building. The writer would look smarter today if he had recognized the implications of the fact that stocks were selling for less than their underlying asset value, and that companies were buying up other companies for that reason. But he didn‟t. He also didn‟t ask why, if it was smart for companies to buy other companies‟ shares, it didn‟t make sense for investors to buy those same shares. (Note: it was largely the ability to buy companies cheaper in the stock market than you could build them that gave pioneers of leveraged buyouts such as KKR, Apax and Warburg Pincus the great returns on their purchases in the 1970s.) It would take a sustained bull market for a couple of years to attract broad-based investor interest and restore confidence. This one reminds me of my absolute favorite Yogi-ism: “Nobody goes [to that restaurant] anymore. It‟s too crowded.” Wait a minute: how can a restaurant be crowded if nobody goes there? Likewise, in this case, according to the writer, it will take a bull market to attract investor interest and confidence. That sounds reasonable. But isn‟t investor interest and confidence a prerequisite for a bull market? Without it, how can a bull market get started? The answer is that when prices are low enough, stocks can begin to rise without help from a fullfledged bull market, just as when they‟re high enough, stock prices can collapse under their own weight. The bottom line here is simple, and I‟m thoroughly convinced of it: Common sense isn’t common. The crowd is invariably wrong at the extremes. In the investing world, everything that’s intuitively obvious is questionable and everything that’s important is counter-intuitive. And investors prove repeatedly that they can be less logical than Yogi.
年轻的代价
让我们回想一下加尔布雷思的那句话:“过往的经验……被摒弃了,成了那些缺乏洞察力、欣赏不了当下奇迹之人的原始避难所。”换句话说,当一股火热的新投资潮流兴起,某个理念被推高到泡沫级别时,
The Penalty of Youth Let‟s think back to Galbraith‟s statement that “Past experience . . . is dismissed as the primitive refuge of those who do not have insight to appreciate the incredible wonders of the present.” In other words, when a hot new investment fad gets rolling and an idea is elevated to bubble status,

那些记得过去的人——或许会指出优点被夸大、价格太高——却被斥为“太老了,跟不上时代。”
1968 年,乔治·古德曼以笔名亚当·史密斯写下的《金钱游戏》中,有个角色叫温菲尔德大帝。尽管他是经纪公司的元老级人物,却能靠当天的热门股赚到钱。有人问他怎么做到的,他说:“我对当前市场的解决办法:孩子们。这是孩子的市场……我家孩子的优势在于,他们太年轻,不记得任何坏事,而且他们赚得太多,觉得自己不可战胜。”这与加尔布雷思的观察如出一辙。
换句话说,老手往往被经验和历史常态束缚,于是错过了“新事物”。只有那些不受这些条条框框约束的人,才能充分参与最新的奇迹……只要它还在持续。
《股市之死》大量倚重这条推理思路,但方向正好相反。它说,你得年轻,不是去理解新奇迹,而是去注意到旧有支柱的过时:
只有老年人,那些没弄懂国家金融市场变化、或无力适应变化的人,还在守着股票。
如今,那种把买入优质股票当作一生积蓄和退休基石的旧态度早已消失。一位年轻的美国高管说:“你最近去参加过美国股东大会吗?全是老古董。股市根本不是热闹所在。”
而支撑这种“游戏已永久改变”的坚持,其根基始终是什么?投资界最危险的四个字:这次不一样。
当投资者选择相信历史估值标准已无关紧要;相信某个行业或产品能永远保持卓越增长和盈利能力;或相信某类资产或某个市场能永远跑赢其他一切,不管过程中价格涨到多高——也就是说,大树能长到天上去——泡沫几乎总是被一种坚定信念托底:这次不一样。《商业周刊》当年搬出了这样的支持论据:
南卫理公会大学商学院院长艾伦·科尔曼说:“我们进入了一个新的金融时代。旧规则不再适用。”
当你看到或听到这类话时,应该高度警惕。有时世界确实会变,过去变得无关紧要,但大多数时候,我会站在赌注的另一边。
those with memory of the past – who might point out that the merits are overstated and the price is too high – are dismissed as “too old to get it.” The Money Game, written in 1968 by George Goodman under the pseudonym Adam Smith, included among its characters the Great Winfield. Even though he was the dean of the brokerage office, he was able to make money in the hot stocks of the day. When asked how, he said, “My solution to the current market: kids. This is a kids‟ market. . . . The strength of my kids is that they are too young to remember anything bad, and they are making so much money they feel invincible.” This exactly parallels Galbraith‟s observation. In other words, veterans are often held back by experience and historic norms, and thus they miss out on the “new thing.” Only those who are free of those strictures can participate fully in the latest miracle . . . as long as it lasts. “The Death of Equities” leaned heavily on this line of reasoning, but in the opposite direction. You have to be young, it said, not to comprehend the new miracle, but to note the obsolescence of the old standby: Only the elderly, who have not understood the changes in the nation‟s financial markets, or are unable to adjust to them, are sticking with stocks. Today, the old attitude of buying solid stocks as a cornerstone for one‟s life savings and retirement has simply disappeared. Says a young U.S. executive: “Have you been to an American stockholders‟ meeting lately? They‟re all old fogeys. The stock market is just not where the action‟s at.” And what consistently provides the foundation for this insistence that the game has permanently changed? Four of the most dangerous words in the investment world: it’s different this time. When investors choose to believe that historic valuation standards have become irrelevant; that one industry or product can maintain superior growth and profitability in perpetuity; or that one asset or market can outperform all the others forever regardless of how high its price goes in the process – that is, that trees can grow to the sky – the bubble is invariably undergirded by a steadfast belief that it‟s different this time. Here‟s the support BusinessWeek advanced: Says Alan Coleman, dean of Southern Methodist University‟s business school, “We have entered a new financial age. The old rules no longer apply.” When you see or hear words like these, you should go on high alert. Sometimes the world changes and the past becomes irrelevant, but most of the time I‟ll take the other side of that bet.
探寻真相
从某种意义上说,理解市场就像学数学。你不必对底层主题的细节了如指掌,也能判断一个结论是否讲得通。你只需要能够运用原则,分清逻辑与谬误,并排除情绪和心理带来的有害影响。
Getting to the Truth In some ways, understanding the market is like mathematics. You don‟t have to be knowledgeable regarding the specifics of the underlying subject matter to know whether a conclusion makes sense. You just have to be able to apply principles, tell logic from illogic, and exclude the deleterious effects of emotion and psychology.

我们来按照这个思路剖析《股票之死》。文中观点是,通胀已经侵蚀了经济和企业的前景,而且毫无改善的希望,所以人们纷纷认输离场、抛售股票。其他东西成了新宠,吸引了原本投向股票的资金。共同基金投资者把注意力转到了别处。大多数公司发行新股没人买,因为买家寥寥。过去十年,股票的绝对回报微乎其微,实际回报为负。它们的售价跌破重置价值,可见市场心态有多悲观。负面因素一长串,却看不到任何实质缓解的可能——这就是作者笔下“过去十年股市遭遇的、几乎无穷无尽的坏事”。
这些负面因素,普通投资者看得一清二楚,也由此得出了悲观的结论。但一个讲逻辑、有洞察力的人,而不是只看表象、凭情绪行事的人,看到的景象截然不同。
他看到的是一个不受宠的资产类别。他看到股票已经便宜了十年——尤其把股息从回报里剔除、再看价格与盈利之比时,更是如此。他看到这些证券的定价低于其背后资产的价值。他看到资本外流——这非但不是坏事,反而压低了价格,一旦资金流逆转,就可能引发强劲的价格反弹。最重要的是,他看到的是一种没有被注入任何乐观情绪的资产类别。
如果让我只说一条判断某样东西是否便宜的标准,那就是看它的价格里蕴含了多少乐观情绪。
不管一项资产的基本面前景有多好,只要投资者在定价时注入了过多的乐观情绪,它就不会便宜。互联网泡沫就是这样:互联网被寄望改变世界,它确实做到了,但当围绕它的乐观情绪被证明过度时,股价便遭到重创。
反过来,不管一项资产的前景有多差,只要价格里几乎没有或完全没有注入乐观情绪,它就很容易成为便宜货,能以有限的风险提供超额的回报。
即便“故事”很糟糕,资产的价格也不太可能下跌(除非是在极短的时间内),除非故事进一步恶化,或者乐观情绪消退。而如果价格里压根没有乐观情绪,后者自然不可能发生。
正是这套逻辑,让我在 2008 年底金融危机最凶险的时刻仍能保持乐观。当时的前景糟得不能再糟——全面崩溃——而价格显然没有包含任何乐观成分。既然如此,买入怎么会是错误呢(只要世界没有末日)?
在《潮水退去》(2008 年 3 月 18 日)一文中,我描述了熊市的三个阶段。第三个阶段是所有人都确信事情只会变得更糟。这几乎总是代表着一个巨大的买入机会。而《股票之死》记录的,恰恰就是这种程度的悲观情绪。
Let‟s dissect “The Death of Equities” in that vein. What it says is that inflation has eaten into the outlook for the economy and companies, and there‟s no hope for improvement. Thus people have been throwing in the towel and selling stocks. Other things have come into vogue, attracting the capital that used to be invested in stocks. Mutual fund investors have turned their attention elsewhere. Most corporations can‟t issue new equity because of the dearth of buyers. Stocks have gone through a decade in which their absolute return was negligible and their real return was negative. They‟re selling below replacement value, showing how poor psychology is. They face a litany of negatives, without any real possibility of relief; that‟s the writer‟s “nearly endless string of unhealthy things that have happened to the stock market over the past decade.” The negative factors are clear to the average investor. And from them he draws negative conclusions. But the person who applies logic and insight, rather than superficial views and emotion, sees something very different. He sees an asset class that is unloved. He sees stocks that have cheapened for a decade – once dividends have been subtracted from the returns, and especially when prices are viewed relative to earnings. He sees securities that are priced below the value of the underlying assets on which they have a claim. He sees outflows of capital that, rather than being a negative, have lowered prices and can give rise to a strong price rebound when and if they reverse. Most of all, he sees an asset class to which no optimism is being applied. If I were asked to name just one way to figure out whether something’s a bargain or not, it would be through assessing how much optimism is incorporated in its price. No matter how good the fundamental outlook is for something, when investors apply too much optimism in pricing it, it won‟t be a bargain. That was the story of the Internet bubble; the Internet was expected to change the world, and it did, but when the optimism surrounding it proved to have been excessive, stock prices were decimated. Conversely, no matter how bad the outlook is for an asset, when little or no optimism is incorporated in its price, it can easily be a bargain capable of providing outsized returns with limited risk. Even with a bad “story,” the price of an asset is unlikely to decline (other than perhaps in the very short term) unless the story deteriorates further or the optimism abates. And if there‟s no optimism built into its price, certainly the latter can‟t happen. It was primarily this line of reasoning that allowed me to feel positive in the teeth of the financial crisis in late 2008. The outlook was as bad as it could get – total meltdown – and prices clearly incorporated zero optimism. How, then, could buying be a mistake (providing the world didn‟t end)? In “The Tide Goes Out” (March 18, 2008), I described the three stages of a bear market. The third stage occurs when everyone becomes convinced that things can only get worse. Invariably this represents a great buying opportunity. And certainly it was such a level of negativity that “The Death of Equities” documented.

所以,一位有洞察力、不动声色、敢于逆向思考的投资者,读到《股市之死》这样的文章时,会得出一个结论:情况已经坏到不能再坏了。而如果事情坏不到哪儿去,那最终很可能会转好。道理就这么简单,谈不上什么科学性。如果 1979 年年中人们觉得事情只会更糟,那也就没有什么乐观情绪可以消散了。这意味着,那串负面清单其实预示了完全不同的结局:股市的复兴。事实也正是如此。
标普 500 指数在 1979 年,也就是《股市之死》发表的那一年,上涨了 18.4%,随后 20 年年均涨幅达到 18.9%。这期间只有两个下跌年份:1982 年微跌 4.9%,1990 年下跌 3.1%。这肯定是现代史上最好的 21 年。重要的是,1979 年积累起来的负面因素被过度悲观地贴现,为这轮上涨搭好了舞台。
早在 1993 年 2 月——这份备忘录要是纸质版,恐怕早就泛黄了,好在电子版不会变色——我写过一篇文章,题为《预测的价值,或者说这雨到底是从哪儿来的?》。文中讨论了一个现象:预测者总是倾向于做外推,尤其是当某个趋势沿着一个方向持续很久时。他们往往断言它会永远走下去……而恰恰就在它越来越可能回归均值的时候,他们越发坚信这一点。
在那篇文章里,我提到加州经历过一场五年大旱。科学家通过研究古树得出结论,五十年一遇的大旱也无法排除。结果,仅仅几个月后,暴雨就倾盆而至。
事情往往就是这样。当一个东西朝着一个方向走了一段时间,人们就越来越相信它会永远如此……而偏偏就在反转的可能性越来越大的时候,他们这么想。这正是《股市之死》最大的毛病。外推者刚对股市认了输,逆向投资者却正好该转为乐观。
而且,这一幕永远会重演。
So the insightful, unemotional, contrarian investor will read an article like “The Death of Equities” and conclude that things are about as bad as they can get. And if things can‟t get worse, they‟ll probably get better eventually. It‟s no more scientific than that. If in mid-1979 people thought things could only get worse, there was no optimism to evaporate. That meant the litany of negatives actually foreshadowed something very different: The Rebirth of Equities. And that’s exactly what happened. The S&P 500 gained 18.4% in 1979, the year “The Death of Equities” was written, and went on to average 18.9% a year for the next 20 years. There were only two down years during that span: a measly 4.9% in 1982 and 3.1% in 1990. This has to have been the best 21-year period in the modern era. Importantly, the stage had been set for this rise in 1979 by the accumulation and excessively pessimistic discounting of negatives. Way back in February 1993 – it would be yellowed by now, except that electronic copies don‟t turn yellow – I wrote a memo entitled “The Value of Predictions, or Where‟d All This Rain Come From?” One of the things it discussed was the tendency of forecasters to extrapolate, especially when a trend has gone in one direction for a long time. They tend to conclude it will go that way forever . . . and increasingly so just as it becomes more likely to revert to the mean. In the memo, I mentioned that California had undergone a five-year drought. And that scientists had concluded from looking at ancient trees that a fifty-year drought couldn‟t be ruled out. And that torrential rainstorms had begun just a few months later. That‟s the way it goes. As something goes in one direction for a while, people conclude increasingly that it always will . . . often just when the likelihood grows that it will reverse instead. And that was the greatest shortcoming of “The Death of Equities.” The extrapolator threw in the towel on stocks, just as the time was right for the contrarian to turn optimistic. And it will always be so.
人算不如天算
事后看,写《股票已死》的人,在底部确实过于悲观了。但过于悲观并非唯一的陷阱。大多数人在顶部,同样容易过于乐观。
与《股票已死》形成另一极的,是 1990 年代沃顿商学院备受尊敬的金融学教授、著有《股票长线法宝》的杰里米·西格尔的研究。西格尔的研究显示,在近两个世纪里,从未有过一个 30 年期里股票跑输现金、债券和通胀,而这样的 10 年期也极为罕见。基于这一历史记录的一致性,西格尔将股票标定为非常安全的资产(只要你长期持有)。事实上,我听他对听众说过,风险规避型投资者的净资产应有 80% 以上配置在股票上,而风险承受型投资者则应该超过 100%。
西格尔的研究助长了 1990 年代弥漫的股票狂热。而且随着股票表现越好,人们的胃口就越大。1995-1999 年期间,标普 500 指数的年复合回报率高达 28.6%,是历史上最强劲的五年。这种狂热所反映的热情极具爆炸性。当时流行的观点是:股票——尤其是科技股——只会上涨,而且必须比其他任何资产涨得更快。
Go Around, Come Around It’s easy with the benefit of hindsight to see that the writer of “The Death of Equities” was too negative at the bottom. But being too negative isn’t the only pitfall. Most people also tend to be too positive at the top. The bookend to “The Death of Equities” is the work published in the 1990s by Jeremy Siegel, a highly respected professor of finance at the Wharton School and the author of Stocks for the Long Run. Through his work, Siegel showed that in almost two centuries, there had never been a 30year period in which stocks didn‟t outperform cash, bonds and inflation, and very few such tenyear periods. Based on the consistency of this record, Siegel labeled stocks very safe (as long as you hold them for the long run). In fact, I heard him tell an audience that risk-averse investors should have 80-odd percent of their net worth in stocks, and risk-tolerant investors should have well over 100%. Siegel‟s research contributed to the fervor for equities that characterized the 1990s. And as stocks did better, the appetite for them rose. The period 1995-99 saw a compound average return of 28.6% on the S&P 500, the greatest five years in history. The ardor this reflected was explosive. Arguments were advanced to the effect that stocks – and tech stocks in particular – could only rise, and that they had to rise faster than anything else.

这次的敌人依旧是外推法。平均年回报率从 1929 年至 1980 年的约 10%,上升到 1980 年至 1989 年的 20.4%,再到 1995 年至 1999 年的 28.6%。但投资者得出了错误的结论,恰好与“股票之死”的观点相反:他们认为好日子只会一直持续下去。然而:
他们忘了,长期来看,股票的收益主要源于企业利润的增长,而利润不可能以每年 20% 到 30% 的速度增长。
他们忽视了这样一种可能:1990 年代的超高回报是向未来借来的。
他们不曾想过,对股票的狂热追捧是否已把价格推到了危险的高度。
他们问“股票的历史回报率是多少?”然后根据这个令人满意的答案买入。但他们没有问“在股票连续 21 年每年上涨近 19% 之后,历史回报率是多少?”或者“以 30 多倍的市盈率买入股票,历史回报率又是多少?”后两个问题的答案会截然不同。
外推法是这些疏漏的根源,它忽视了这样一种可能性:事件已经改变了环境,从而也改变了前景。
关于旱灾和雨水,我说了什么?当然,在 1990 年代股票表现足够好、足以激发最大程度的看多情绪和最大规模的配置之后,它们的回报就注定要回归均值。于是,截至去年年底的三十年里,股票表现首次落后于债券。
这里的教训是什么?不是历史总会重演,也不是历史从不重演。不是股票只会涨或只会跌。而是,通向某个时间点的趋势,会对人们的思维和环境产生深远影响,从而也影响此后将出现的趋势。价格上涨增加风险,价格下跌增加机会。大多数投资者和观察者往往在顶部过于乐观,在底部过于悲观。
这些教训弥足珍贵。研究历史能让人看清它们,而无视历史则可能让它们变得致命。
Again the enemy was extrapolation. The average annual return had risen from about 10% for 1929 to 1980, to 20.4% for 1980 to 1989, and to 28.6% for 1995 to 1999. But investors drew the wrong conclusions, the inverse of those of “The Death of Equities”: they thought the good times could only roll on. However: They forgot that in the long run the gains of stocks stem primarily from growth in corporate profits, and that profits don‟t grow anywhere near 20-30% a year. They ignored the possibility that the ultra-high returns of the 1990s had borrowed from future returns. They failed to wonder whether the adoration of stocks had lifted their prices to dangerous heights. They asked “What has been the historic return on stocks?” and bought based on the favorable answer. But they didn‟t ask “What has been the historic return on stocks after they‟re risen almost 19% a year for 21 years?” or “What has been the historic return on stocks if bought at price/earnings ratios in the 30s?” The answer to these latter questions would have been very different. Extrapolation was at the root of these omissions, disregarding the possibility that events had changed the environment and thus the outlook. What did I say about the drought and rain? Of course, after stocks had done well enough in the 1990s to encourage maximum bullishness and maximum allocations, their returns were primed for regression to the mean. And so stocks lagged bonds for the first time in the thirty years ending late last year. What’s the lesson here? Not that history always repeats, or that it never repeats. And not that stocks can only do well or only do poorly. But rather that the trends that lead up to a point in time have a profound effect on people’s thinking and on the environment, and thus on the trends that will occur thereafter. That price gains increase danger and price declines increase opportunity. And that most investors and observers tend to be too positive at the top and too negative at the bottom. These lessons are invaluable. The study of history makes them clear, just as ignorance of history makes them potentially lethal.
再来一轮
让我吃惊的是,每每快要写完一份备忘录时,我总能碰上恰到好处的收尾材料。这次也不例外,我是在 3 月 12 日的《华尔街日报》上找到的,而那天正是我开始动笔的第二天。
那篇文章题为《为什么股票比你想象的更危险》,作者兹维·博迪和蕾切尔·塔克在文中——依我看——又来了一通“股票之死”式的老生常谈。我不打算深谈这篇文章,但想指出其中几处不合逻辑的地方:
文章说,“尽管金融行业一再保证,股票始终是危险的投资。”这话说了等于没说。股票的前景向来不确定,甚至可以说风险不小,但必须指出的是,股票的风险并不是一成不变的。它们在某些时候风险更高,
One More Round I‟m amazed at how often, just as I‟m about to complete a memo, I come across the right coda with which to bring it to an end. This time I found it in The Wall Street Journal of March 12, just a day after I‟d started writing. In an article entitled “Why Stocks Are Riskier than You Think,” Zvi Bodie and Rachelle Taqqu go through – in my opinion – another Death of Equities-like recitation. I won‟t discuss the article in depth, but I will point out some of its illogicalities: It says “despite the assurances of the financial industry, stocks are always a risky investment.” This isn‟t very helpful. The outlook for stocks is always uncertain, perhaps even risky, but it‟s essential to note that they aren‟t always equally risky. They‟re riskier

当估值处于高位、价格蕴含强烈乐观情绪时,持有股票风险反而更大;而当情况相反时,风险则小得多(参见 1979 年)。
文章称“持有(股票)的时间越长,遭遇低迷期突袭的概率就越大。”我认为这种说法极具误导性。做任何事时间越长,坏事发生的概率自然越大。但这并不意味着你不该去做,或者短期操作就更安全。也许短期参与者会恰好踩错时机,一头撞上糟糕的阶段。又或许仅仅短期持有股票,他会错失长期收益。问题不在于长期股票投资者是否会遭遇坏事,而在于综合考虑好时期与坏时期后,整体上更可能发生什么。以及,鉴于自身具体情况,投资者能否在等待好时光来临之际熬过坏时光。
在决定准退休人员能承受多大风险时,作者们提到不希望再次看到 2008 年那种 30% 至 40% 的损失。但用几十年一遇的最坏时期来反对投资股票,与用最好时期来鼓吹投资股票同样不可取。关键并非最好或最坏的可能结果(甚至也不是最可能发生的单一结果)。关键在于结果的范围及其各自的概率与后果。任何单一观察都无法提供很有价值的视角。
作者们花最多篇幅推荐的是所谓的“零成本领口”策略,例如,以 136 美元买入标普 500 ETF,以 116 美元买入看跌期权(确保该价位以上的损失得到保障),再以卖出 143 美元看涨期权(放弃该价位以上的收益)所得资金来支付看跌期权费用。好消息是,一个期权的收益恰好支付另一个期权的费用,领口策略本身零成本,下行风险限制在 15%。但坏消息是,与你 15% 的最大损失对应,你的最大收益也只有 6%。我对这种取舍并不热衷。该策略的好处大体上是虚幻的,姿态则过于保守。
这篇文章并非毫无价值。我的抱怨在于它过于简单化——而关于投资,最不该做的就是让它看起来简单。此外,在股票估值看似合理之际,文章还偏向负面立场。
过去十二年间,股票几乎没带来任何回报。
三十年期股票回报率首次低于债券回报率。
标普 500 指数价格仍比 2000 年高点低 8%,而同期其成分公司每股收益却几乎翻了一番。
因此,标普 500 指数的市盈率落至十几倍的低位,相比二战后常态水平有大幅折价,也远低于峰值时期的 30 多倍。
与 1979 年一样,机构投资者对股票失去兴趣,日益转向另类资产。1979 年至 1999 年间那种对股票的热恋似乎已告终结。
股票配置大幅削减,转而投向债券和另类资产。例如,根据 3 月 15 日《本周所学》(What I Learned This Week)报道,“ICI 数据显示,2007 年至 2011 年间,美国股票型共同基金净赎回 4080 亿美元;同期,美国债券基金净流入 7920 亿美元。”
when valuations are high and prices embody great optimism, and they‟re much less risky when the reverse is true (see 1979). It says “the longer you hold [stocks], the better your chances of getting blindsided by a downturn.” I find this highly misleading. The longer you do anything, the better the chance that something bad will happen. But that doesn‟t mean you shouldn‟t do it, or that it‟s safer to do it for just a short time. Maybe the participant for a short period will time it just wrong and run straight into a bad patch. And maybe by holding stocks for just a short time he‟ll miss out on the long-term benefits. The question isn‟t whether something bad can happen to the long-term investor in equities, but what‟s likely to happen overall, considering good times as well as bad. And whether, given his particular circumstances, an investor can survive the bad while waiting for the good to arrive. In deciding how much risk a prospective retiree can bear, the authors make reference to not wanting to see 2008-style losses of 30% to 40% ever again. But using the worst time in generations to argue against investing in stocks is no better than using the best time to argue for it. What matters isn‟t the best or worst possible outcome (or even the single most likely outcome). What matters is the range of outcomes and their respective probabilities and consequences. No one observation provides a very useful perspective. The strategy the authors spend the most time recommending is what‟s called a “zero-cost collar” where, for example, you buy an S&P 500 ETF at $136, buy a put at $116 (ensuring against losses beyond that) and get the money with which to buy the put by selling a call at $143 (giving up any gains above that). The good news is that one option pays for the other so the collaring is free, and that your downside is limited to 15%. But the bad news is that to go with your maximum loss of 15%, you have a maximum gain of 6%. I‟m not crazy about that tradeoff. The benefits of the strategy seem largely illusory and the posture excessively defensive. This article isn‟t without merit. My complaint is that it‟s simplistic – and the last thing that should be done regarding investing is to make it appear simple. It‟s also biased to the negative side at a time when stocks appear reasonably situated. Stocks have returned almost nothing over the last twelve years. For the first time, the 30-year return on stocks has been below the return on bonds. The price of the S&P 500 index is still 8% below its 2000 high, while its companies‟ earnings per share have nearly doubled over the intervening period. Thus the p/e ratio on the S&P 500 is in the low double digits, a substantial discount from the post-World War II norm and down from the low 30s at the peak. Just as in 1979, institutional investors have lost interest in equities and are looking increasingly to alternatives. The love affair with equities that ran from 1979 to 1999 seems to be over. Allocations to equities have been cut substantially in favor of bonds and alternatives. For example, according to What I Learned This Week of March 15, “The ICI reports that $408 billion was redeemed from U.S. equity mutual funds between 2007 and 2011 and $792 billion was invested in U.S. bond funds in the same period.”

故事不像 1979 年那时那么无望,但整体仍是消极的。因此,虽然我不指望股市会出现像“股票之死”之后那样的反弹,但要构想出积极的情景并不难。
The story isn‟t as hopeless as it was in 1979, but it is uniformly negative. Thus, while I don‟t expect an equity rally anything like what followed on the heels of “The Death of Equities,” I don‟t find it hard to conjure up positive scenarios.

媒体通常会把事情搞错,而最受关注的那些报道往往极度耸人听闻,错得也最离谱。这正是普通投资者处于劣势的众多原因之一。1979 年,《股市之死》一文会在极具吸引力的低位让你逃离或远离股市;20 世纪 90 年代,西格尔教授的研究会在高位促使你增持股票;而现在这篇新文章,在估值低于平均水平、投资者转向悲观、企业表现良好的时候,却主张远离股票。
这里最大的讽刺在于,那些做线性外推的人其实自认为尊重历史:他假设的是正在进行的趋势会延续。但真正值得他关注的历史,并非资产价格近期的涨跌,而是大多数事物最终都证明具有周期性,倾向于从极端摆回均值这一事实。历史充分表明,投资者和评论员都有这样的倾向:负面因素积聚、价格低迷时悲观,形势向好、价格飞涨时乐观。历史的教训极具启发性。应用它们并不容易,但绝不能忽视。
The media usually gets it wrong, and the pieces that get the most attention tend to be highly sensational and to get it the most wrong. This is one of the many reasons why the deck is stacked against the average investor. “The Death of Equities” would have gotten you out or kept you out of the stock market at very attractive levels in 1979. Professor Siegel‟s work would have gotten you to increase your holdings at high prices in the 1990s. And this new article argues against stocks at a time when valuations are below average, investors have turned against them, and companies are doing well. The great irony here is that the extrapolator actually thinks he‟s being respectful of history: he‟s assuming continuation of a trend that has been underway. But the history that deserves his attention isn‟t the recent rise or fall of an asset‟s price, but rather the fact that most things eventually prove to be cyclical and tend to swing back from the extreme toward the mean. History amply demonstrates the tendency of investors and commentators alike to be pessimistic when the negatives collect, depressing prices, and optimistic when things are going well and prices are soaring. The lessons of history are highly instructive. Applying them isn’t easy, but they mustn’t be overlooked.
