牛市韵脚

Bull Market Rhymes

我在写作中引用大量格言警句,但最常参考的其实就那么寥寥数条。其中我最喜欢的一条常被归于马克·吐温名下:“历史不会重演,但总会押韵。”史料证实吐温在 1874 年说过前四个词,但没有确凿证据表明他讲过后面的部分。多年来,许多人也说过类似的话,1965 年精神分析学家西奥多·赖克在一篇题为《不可触及者》的文章中表达了基本相同的意思。他用的词比我多几个,但我觉得他的表述最为精妙:

周期循环往复,起起落落,但事态进程本质相同,只是略有出入。有人说历史会重演,这话或许不太确切,它不过是在押韵。

投资历史的事件不会重演,但熟悉的主题确实会反复出现,尤其是行为层面的主题。这些才是我研究的对象。

过去两年里,我们亲眼目睹了赖克所写的起落沉浮的戏剧性例证。而投资者行为中一些经典主题的再现,也让我深受触动。这些就是本备忘录的主题。

我想先说清楚,这份备忘录与评估市场未来的可能走向毫无关系。看涨情绪源于 2020 年 3 月疫情触底后的反弹;此后,经济内部(通胀)和外部(乌克兰)都出现了严重问题;市场也经历了大幅回调。没有人——包括我在内——知道这些因素叠加起来对未来意味着什么。

我写这篇文章,只是为了把近期事件放进历史背景中审视,并指出几条隐含的教训。这很重要,因为我们要回溯 22 年——回到 2000 年科技媒体电信泡沫破裂之前——才能看到我所谓真正的牛市以及随之而来的熊市的终结,而我猜许多读者进入投资世界的时机太晚,未能亲历那段经历。你可能会问:“那 2008-09 年全球金融危机之前和 2020 年疫情相关崩盘之前的市场上涨又怎么说?”在我看来,这两次情况中,先前的上涨都是渐进的,而非抛物线式的;并非由过热心理驱动;也没把股价推到疯狂的高度。而且,高股价并非这两场危机的成因。前者的过度在于房地产市场以及次级抵押贷款支持证券的创造,后者的崩盘则是新冠到来以及政府为限制疫情蔓延决定关闭经济的结果。

我上文提到的“真正的牛市”,指的不是 Investopedia 上诸如以下之类标准定义:

While I employ a great many adages and quotes in my writings, my main go-to list consists of a relatively small number. One of my favorites is widely attributed to Mark Twain: “History doesn’t repeat itself, but it does rhyme.” It’s well documented that Twain used the first four words in 1874, but there’s no clear evidence that he ever said the rest. Many others have said something similar over the years, and in 1965 psychoanalyst Theodor Reik said essentially the same thing in an essay titled “The Unreachables.” It took him a few more words, but I think his formulation is the best: There are recurring cycles, ups and downs, but the course of events is essentially the same, with small variations. It has been said that history repeats itself. This is perhaps not quite correct; it merely rhymes. The events of investment history don’t repeat, but familiar themes do recur, especially behavioral themes. It’s these that I study. In the last two years, we’ve seen dramatic examples of the ups and downs Reik wrote about. And I’ve been struck by the reappearance of some classic themes in investor behavior. They’ll be the topic of this memo. I want to mention up front that this memo has nothing to do with assessing the markets’ likely direction from here. Bullish behavior came out of the pandemic-related bottom of March 2020; since then, significant problems have developed inside the economy (inflation) and outside (Ukraine); and there’s been a significant correction. No one, including me, knows what the sum of those things implies for the future. I’m writing only to place recent events in the context of history and point out a few implied lessons. This is important, because we have to go back 22 years – to before the bursting of the tech-media-telecom bubble in 2000 – to see what I consider a real bull market and the ending of the resultant bear market, and I imagine many of my readers entered the investment world too late to have experienced that event. You may ask, “What about the market gains that preceded the Global Financial Crisis of 2008-09 and the pandemic-related collapse of 2020?” In my view, in both cases, the preceding appreciation was gradual, not parabolic; it wasn’t driven by overheated psychology; and it didn’t take stock prices to crazy heights. Moreover, high stock prices weren’t the cause of either crisis. The excesses in the former lay in the housing market and the creation of securities backed by sub-prime mortgages, and the latter collapse was a consequence of the arrival of Covid-19 and the government’s decision to shut down the economy to limit the spread of the disease. When I refer above to “a real bull market,” I’m not talking about standard definitions such as these from Investopedia: • •

金融市场中资产或证券价格持续上涨的一段时期。

股价下跌 20% 后通常上涨 20% 的情况。

A period of time in financial markets when the price of an asset or security rises continuously A situation in which stock prices rise by 20%, usually after a drop of 20%

第一个定义太过平淡,捕捉不到牛市的情感本质;第二个则是在追求虚假的精确。牛市不应该用百分比的价格变动来定义。对我来说,最好用它的感受、背后的心理,以及这种心理导致的行为来描述。

(我开始投资时,牛熊市的数值标准还没发展出来,我认为这类标尺毫无意义。看看最近几篇报纸文章就知道了。5 月 20 日,标普 500 指数从高点回落,跌幅突破了“神奇”的 20% 门槛;于是 5 月 21 日《金融时报》写道,“华尔街股市昨日跌入熊市……”但尾盘反弹使最终跌幅收窄至 20% 以下,同一天《纽约时报》的标题却是,“标普 500 下跌……但躲过熊市。”标普 500 跌 19.9% 还是 20.1%,真有那么重要吗?我更偏爱老派的熊市定义:让人神经紧绷。)

过度与修正

我的第二本书是《掌握市场周期:让胜算站在你这边》。众所周知,我研究周期,也相信周期。作为投资者,这些年我经历了好几次重要的周期,也从中得到了教训。我相信,了解我们在市场周期中所处的位置,能让我们对接下来会发生什么有所提示。然而,当我写到那本书大约三分之二的时候,一个我之前从没想过的问题浮现在我脑海中:为什么会有周期?

比如,标普 500 指数自 1957 年采用现形式以来,65 年间平均年回报率略高于 10%,那为什么它不每年都正好回报 10%?再更新一下我在备忘录《快乐中间点》(2004 年 7 月)里提出的问题:这期间它的年回报率只有 6 次落在 8% 到 12% 之间,为什么 90% 的时间都偏离均值那么远?

思考这个问题一段时间后,我想到了一个我认为能解释它的答案:过度与修正。如果股市是一台机器,那或许可以合理预期它会随时间稳定运转。但相反,我认为心理对投资者决策的巨大影响,在很大程度上解释了市场的剧烈波动。

当投资者变得高度看涨时,他们倾向于认为(a)一切都会永远上涨,(b)不管他们花多少钱买入一项资产,总会有别人出更高的价钱从他们手里买走(“博傻理论”)。因为乐观情绪高涨:

The first of these is too bland, failing to capture a bull market’s emotional essence, and the second attempts false precision. A bull market shouldn’t be defined as a percentage price movement. For me, it’s best described by what it feels like, the psychology behind it, and the behavior that psychology leads to. (I started investing before the development of numerical criteria for bull and bear markets, and I consider such yardsticks meaningless. Take a look, for example, at a couple of recent newspaper articles. On May 20, the S&P 500 Index’s decline from the top passed the “magic” 20% threshold; thus on May 21 the Financial Times wrote, “Wall Street stocks slumped into a bear market yesterday . . .” But because a late rally reduced the final decline to just under 20%, the headline of the same day’s New York Times read, “S&P 500 Drops . . . but Evades Bear Market.” Does it really matter whether the S&P 500 is down 19.9% or 20.1%? I prefer the old-school definition of a bear market: nerve-racking.) Excesses and Corrections My second book is Mastering the Market Cycle: Getting the Odds on Your Side. It’s well known that I’m a student of cycles and a believer in cycles. I’ve lived through (and been schooled by) several significant cycles during my years as an investor. I believe understanding where we stand in the market cycle can give us a hint regarding what’s coming next. And yet, when I was about two-thirds of the way through writing that book, a question dawned on me that I hadn’t considered before: Why do we have cycles? For example, if the S&P 500 has returned just over 10% a year on average over the 65 years since it assumed its present form in 1957, why doesn’t it just return 10% every year? And updating a question I asked in my memo The Happy Medium (July 2004), why has its annual return been between 8% and 12% just six times during this period? Why is it so far from the mean 90% of the time? After pondering this question for a while, I landed on what I consider the explanation: excesses and corrections. If the stock market was a machine, it might be reasonable to expect it to perform consistently over time. Instead, I think the substantial influence of psychology on investors’ decision-making largely explains the market’s gyrations. When investors turn highly bullish, they tend to conclude that (a) everything’s going to go up forever and (b) regardless of what they pay for an asset, someone else will come along to buy it from them for more (the “greater-fool theory”). Because of the high level of optimism: • • • •

股价的上涨速度快于公司利润的增长,飙升到远高于公允价值的水平(向上的过度偏离)。

最终,投资环境令人失望,或价格高企的荒谬变得显而易见,股价便会回落至公允价值附近(修正),继而跌破这一水平。

价格下跌引发进一步的悲观情绪,这一过程最终导致股价远低于股票的实际价值(向下的过度偏离)。

随之而来的逢低买入者进场,促使低迷的股价回升至公允价值附近(修正)。

Stock prices rise faster than company profits, soaring well above fair value (excess to the upside). Eventually, conditions in the investment environment disappoint, and/or the folly of the elevated prices becomes clear, and they fall back toward fair value (correction) and then through it. The price declines generate further pessimism, and this process eventually causes prices to far understate the value of stocks (excess to the downside). Resultant buying on the part of bargain-hunters causes the depressed prices to recover toward fair value (correction).

向上的过度会带来一段高于平均水平的回报期,而向下的过度摆动则导致低于平均水平的回报期。当然,可能还有其他许多因素在起作用,但在我看来,“过度与修正”涵盖了大部分情况。我们在 2020-21 年看到了多次向上的过度,如今正在目睹相应的修正。

The excess to the upside makes for a period of above average returns, and the swing toward excess on the downside makes for a period of below average returns. There can be many other factors at work, of course, but in my view, “excesses and corrections” covers most of the ground. We saw a number of excesses to the upside in 2020-21, and now we’re seeing corrections thereof.

牛市心理

在牛市中,利好因素推动股价上涨,进而提振投资者心理。积极的心理诱发激进的行为。激进的行为推动股价进一步上涨。不断上涨的股价又催生更乐观的心理,促使更多冒险行为。这种向上的螺旋正是牛市的本质。一旦行情启动,便让人觉得势不可挡。

我们在疫情初期见证了资产价格的典型崩盘。例如,标普 500 指数在 2020 年 2 月 19 日创下当时的历史新高 3386 点,随后短短 34 天内下跌三分之一,至 3 月 23 日跌至低点 2237 点。此后,多重力量共同作用,推动价格大幅上涨:

Bull Market Psychology In a bull market, favorable developments lead to price rises and lift investor psychology. Positive psychology induces aggressive behavior. Aggressive behavior leads to higher prices. Rising prices encourage rosier psychology and further risk-taking. This upward spiral is the essence of a bull market. When it’s underway, it feels unstoppable. We saw a classic collapse of asset prices in the early days of the pandemic. For example, the S&P 500 reached a then-all-time high of 3,386 on February 19, 2020 before falling by one-third in just 34 days to a low of 2,237 on March 23. After that, a number of forces combined to produce massive price gains: • • • • • • •

美联储将联邦基金利率降至接近零,财政部也加入其中,宣布了大规模刺激措施。这些行动让投资者确信,这些机构会不惜一切代价稳定经济。降息显著降低了投资在相对比较下看起来有吸引力所需的预期回报。这些因素叠加,迫使投资者去承担不久前还在躲避的风险。资产价格上涨:到 8 月下旬,标普 500 指数已收复失地,并超过 2 月份的高点。FAAMG(Facebook、亚马逊、苹果、微软和谷歌)、软件股及其他科技股大幅飙升,推动市场进一步走高。最终,投资者得出了结论——就像他们在形势向好时常常做的那样——认为市场还会继续这样下去。

The Federal Reserve cut the fed funds rate to roughly zero, and the Fed was joined by the Treasury in announcing massive stimulative measures. These actions convinced investors that these institutions would do whatever it took to stabilize the economy. The interest rate cut significantly reduced the prospective returns required to make investments look attractive in relative terms. The combination of these factors forced investors to bear risks they had been running from just a short time earlier. Asset prices rose: by late August, the S&P 500 had retraced its decline and surpassed its February high. The FAAMGs (Facebook, Amazon, Apple, Microsoft and Google), software stocks, and other tech stocks rose dramatically, pushing the market higher. Eventually, investors concluded – as they often do when things are going well – that they could expect more of the same.

牛市心理最重要的一点,正如上面最后一条要点所述,大多数人将股价上涨视为未来向好的积极信号。许多人因此转为乐观。很少有人怀疑,至今的涨幅可能已经过度,是从未来回报中借来的,并且预示着反转而非延续。

这让我想起了另一句我喜爱的格言——大约 50 年前我学到的首批格言之一——“牛市的三个阶段”:

The most important thing about bull market psychology is that, as cited in the final bullet point above, most people take rising stock prices as a positive sign of things to come. Many are converted to optimism. Relatively few suspect that the gains to date might have been excessive and borrowed from future returns and that they presage reversal, not continuation. That reminds me of another of my favorite adages – one of the first ones I learned, roughly 50 years ago – “the three stages of a bull market”: • • •

第一个阶段,少数有远见的人开始相信情况会好转,

第二个阶段,大多数投资者认识到改善确实正在进行,

第三个阶段,所有人都断定情况会永远好转。

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 concludes that things will get better forever.

有意思的是,尽管市场从 2020 年 3 月的绝望状态一路飙升到 5 月的沸腾行情——很大程度上要归功于美联储——那段时期我遇到最多的情绪却是怀疑。我被问得最多的问题是:“既然环境这么糟糕——疫情肆虐、经济停摆——市场上涨难道不是错的吗?”很难找到任何乐观者。许多买家正是我已故岳父常说的那种“戴手铐的志愿者”:他们买入并非出于意愿,而是迫于无奈,因为现金回报实在太低。而一旦市场开始上涨,人们又害怕掉队,于是追高买入。因此,市场涨势更像是美联储操控资本市场的产物,而非企业基本面改善或乐观情绪的自然结果。直到 2020 年底前后——当时标普 500 指数全年上涨 16.3%,自 3 月低点累计上涨 67.9%——投资者心理才总算赶上了节节攀升的股价。

It’s interesting to note that even though the market moved from despondent in March 2020 to booming in May, largely thanks to the Fed, the most frequent attitude I encountered during that period was dubiousness. And the question I was asked most frequently was “If the environment is so bad – with the pandemic raging and the economy shuttered – isn’t it wrong for the market to rise?” It was hard to find any optimists. Many of the buyers were what my late father-in-law used to call “handcuff volunteers”: they didn’t buy because they wanted to; they bought because they had to, since the return on cash was so low. And once markets started to rise, people were afraid of being left behind, so they chased prices higher. Thus, the market gains seemed to be the result of the Fed’s manipulation of the capital markets, rather than positive corporate developments or optimistic psychology. It was only around the end of 2020 – when the S&P 500 was up by 16.3% for the year and 67.9% from the March bottom – that investor psychology caught up with the booming stock prices.

2020 年的牛市在我记忆中前所未有,因为它基本上没有第一阶段,第二阶段也微乎其微。许多投资者直接从 3 月底的绝望,跳到那年年底的极度乐观。这是一个绝佳的提醒:虽然某些主题确实会重演,但指望历史分毫不差地重复,是一个巨大的错误。

乐观的理由、超级股票,以及新新事物

狂热的牛市是集体歇斯底里的典型例子。到了极端,思维乃至行为都会脱离现实。然而,要让这种情况发生,必须有某种因素激发投资者的想象、压制谨慎之心。因此,应当特别关注一个几乎总是伴随牛市出现的要素:某种新进展、新发明,或者为股价上涨提供的某种新理由。

牛市,按定义来说,其特征就是亢奋、自信、轻信,以及愿意为资产支付高价——所有这些都处于事后看来明显过头的水平。历史一再表明,让这些东西保持在适度范围内至关重要。正因如此,牛市的理智或情感依据,往往建立在某种历史无法用来打折扣的新事物之上。

最后那六个字非常重要。历史充分证明,当(a)市场表现出看涨行为,(b)估值变得过高,以及(c)最新事物被毫不犹豫地接受时,后果往往非常痛苦。每个人都知道——或者应该知道——抛物线式的股市上涨之后,通常会出现 20% 到 50% 的下跌。然而,这些上涨一再出现,反复重演,背后有我在高中英语课上学到的一个说法在推波助澜,叫“心甘情愿地搁置怀疑”。这里还有一句我非常喜欢的引语:

助长……狂热的,还有两个我们这个时代和过去时代都很少注意到的因素。第一是金融记忆的极度短暂。因此,金融灾难很快被遗忘。再因此,当相同或极为相似的情况再次出现时,往往不过几年光景,它们就会被新一代——往往年轻、而且总是极度自信——当作金融界乃至整个经济世界中一项辉煌的创新发现而欢呼。在人类努力的各个领域中,很少有哪个领域像金融世界这样,历史的作用如此微不足道。过去的经验,即便还残留在记忆里,也被斥为那些缺乏洞察力、欣赏不了当下惊人奇迹之人的原始避风港。(约翰·肯尼斯·加尔布雷思,《金融狂热简史》,1990 年——强调为笔者所加)

过去 30 年里,我多次与读者分享这段引语——因为我觉得它极其精妙地总结了若干要点——但我此前没有分享过我对它所描述行为的解释。我不认为投资者是真的健忘。更准确地说,对历史的了解和对谨慎之道的认同,放在天平的一边,而发财致富的梦想放在另一边。后者总是赢。记忆、谨慎、现实主义和对风险的厌恶,只会挡在那个梦想的路上。正因如此,当牛市启动时,合理的担忧常常被抛在一边。

取而代之的,往往是为超出历史常态的估值提供的种种理智上的辩解。1987 年 10 月 11 日,安妮丝·华莱士在《纽约时报》一篇题为《为什么这轮市场周期不一样》的文章中描述了这一现象。当时,乐观思维正被人们热情拥抱,用来为异常高的股价正名,但华莱士说这撑不住:

The bull market of 2020 was unprecedented in my experience, in that there was essentially no first stage and very little of the second. Many investors went straight from hopeless in late March to highly optimistic later in the year. This is a great reminder that, while some themes do recur, it’s a big mistake to expect history to repeat exactly. Optimistic Rationales, Super Stocks, and the New, New Thing Raging bull markets are examples of mass hysteria. At the extreme, thinking and thus behavior become unmoored from reality. In order for this to occur, however, there has to be some factor that activates investors’ imagination and discourages prudence. Thus, special attention should be paid to an element that almost always characterizes bull markets: a new development, invention or justification for the rising stock prices. Bull markets are, by definition, characterized by exuberance, confidence, credulousness, and a willingness to pay high prices for assets – all at levels that are shown in retrospect to have been excessive. History has generally shown the importance of keeping these things in moderation. For that reason, the intellectual or emotional rationale for a bull market is often based on something new that history can’t be used to discount. Those last six words are very important. History amply demonstrates that when (a) markets exhibit bullish behavior, (b) valuations become excessive, and (c) the latest thing is accepted without hesitation, the consequences are often very painful. Everyone knows – or should know – that parabolic stock market advances are generally followed by declines of 20-50%. Yet those advances occur and recur, abetted by what I learned in high school English class to call “the willing suspension of disbelief.” Here’s another of my very favorite quotes: 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, sometimes in only a few years, they are hailed by a new, often youthful, and always supremely self-confident generation as a brilliantly innovative discovery in the financial and larger economic world. 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 the insight to appreciate the incredible wonders of the present. (John Kenneth Galbraith, A Short History of Financial Euphoria, 1990 – emphasis added) I’ve shared that quote with readers many times over the last 30 years – since I think it so beautifully sums up a number of important points – but I haven’t previously shared my explanation for the behavior it describes. I don’t think investors are actually forgetful. Rather, knowledge of history and the appropriateness of prudence sit on one side of the balance, and the dream of getting rich sits on the other. The latter always wins. Memory, prudence, realism, and risk aversion would only get in the way of that dream. For this reason, reasonable concerns are regularly dismissed when bull markets get going. What appears in their place is often intellectual justifications for valuations that exceed historical norms. On October 11, 1987, Anise Wallace described this phenomenon in an article in The New York Times titled “Why This Market Cycle Isn’t Different.” Optimistic thinking was being embraced at the time to justify unusually high stock prices, but Wallace said it wouldn’t hold:

投资中最危险的四个字是“这次不一样”,这是 74 岁的基金经理约翰·坦普尔顿说的。在股市的顶部和底部,投资者总爱用这个理由为自己的情绪化决策辩护。未来一年,许多投资者很可能会重复这四个字,为更高的股价撑腰。但他们应该像对待“支票已寄出”那样,对这话多留个心眼。不管券商或基金经理怎么说,牛市不会永远持续。

用不了一年。仅仅八天后,世界就迎来了“黑色星期一”,道琼斯指数单日暴跌 22.6%。

牛市还有另一个常见借口,就是相信某些行业注定前景辉煌。这适用于 20 世纪 60 年代末的“漂亮五十”成长股、80 年代的磁盘驱动器制造商,以及 90 年代末的电信、互联网和电商公司。人们当时认为,这些发展都能改变世界,因此过去的商业现实不必束缚投资者的想象力和掏钱的意愿。它们确实改变了世界。然而,被认为合理的超高资产估值却没有撑住。

在许多牛市中,总有一类或多类股票被捧成我所说的“超级股票”。它们的快速上涨让投资者越来越乐观。在市场常见的循环过程中,这种日益高涨的乐观情绪又把股价推得更高。而一些正面情绪和升值,又会通过相对价值比较,或是因为投资者整体情绪好转,对其它类别的证券——甚至所有证券——产生积极影响。

在 2020 年至 2021 年点燃投资者热情的名单上,拔得头筹的是 FAAMG 五巨头,它们的市场支配地位和扩张能力前所未见。FAAMG 在 2020 年的惊人表现吸引了投资者的目光,推动了广泛的看涨转向。到 2020 年 9 月(也就是六个月内),这些股票已从 3 月的低点近乎翻倍,较年初上涨 61%。值得注意的是,这五只股票在标普 500 指数中权重很高,所以它们的表现带动指数整体上涨,但这却掩盖了其余 495 只股票逊色得多的表现。超级股票的涨势点燃了投资者的热情,让他们顾不上对疫情持续或其他风险的担忧。

The four most dangerous words in investing are “this time it’s different,” according to John Templeton, the 74-year-old mutual fund manager. At stock market tops and bottoms, investors invariably use this rationale to justify their emotion-driven decisions. Over the next year, many investors are likely to repeat those four words as they defend higher stock prices. But they should treat them with the same consideration they give “the check’s in the mail.” No matter what brokers or money managers say, bull markets do not last forever. It didn’t take a year. Just eight days later, the world experienced “Black Monday,” when the Dow Jones Industrial Average dropped by 22.6% in a single day. Another justification for bull markets is often found in the belief that certain businesses are guaranteed to enjoy a terrific future. This applies to the Nifty-Fifty growth companies in the late 1960s; disc drive manufacturers in the ’80s; and telecom, Internet and e-commerce companies in the late ’90s. Each of these developments was believed to be capable of changing the world, such that the past realities of business need not constrain investors’ imaginations and willingness to pay up. And they did change the world. Nevertheless, the highly elevated asset valuations they were thought to justify didn’t hold. In many bull markets, one or more groups are anointed as what I call “super stocks.” Their rapid rise makes investors increasingly optimistic. In the circular process that often characterizes the markets, this rising optimism takes the stocks to still-higher prices. And some of this positivity and appreciation reflects favorably on other groups of securities – or all securities – through relativevalue comparisons and/or because of the general improvement in investors’ mood. Topping the list of companies that fed investors’ excitement in 2020-21 were the FAAMGs, whose level of market dominance and ability to scale had never been seen before. The dramatic performance of the FAAMGs in 2020 attracted the attention of investors and supported a widespread swing toward bullishness. By September 2020 (that is, within six months), these stocks had nearly doubled from their March lows and were up 61% from the beginning of the year. Notably, these five stocks are heavily weighted in the S&P 500, so their performance resulted in a good overall gain for the index, but this distracted attention from the far-less-impressive performance of the other 495 stocks. The performance of the super stocks inflamed investors’ ardor, enabling them to disregard worries regarding the persistence of the pandemic or other risks.

FAAMG 集团的狂飙成功,为整个科技股板块镀上了一层耀眼的光环。投资者对科技股的需求飙升,而正如投资界一贯的规律,旺盛的需求既鼓励了供给,也为其创造了条件。此间一个显著的衡量指标,便是市场对尚未盈利公司首次公开募股(IPO)的态度。在 20 世纪 90 年代末的科技泡沫之前,不赚钱公司的 IPO 相对罕见。泡沫期间这类 IPO 成为常态,但此后数量又再度回落。在 2020 年至 2021 年的牛市中,不盈利公司的 IPO 迎来大规模复苏,因为投资者轻易便宽容了科技公司扩张规模的雄心,以及生物技术公司为临床试验烧钱的需求。

如果说前景光明的公司为牛市注入了燃料,那么市场上出现的新鲜事物则可能让市场的狂热火上浇油。SPAC(特殊目的收购公司)是近年来一个绝佳的例子。投资者向这些新成立的壳公司开出空白支票用于收购,前提条件有二:其一,若两年内未完成任何收购,投资者可拿回本金并附有利息;其二,若投资者不满意拟议的收购方案,同样可撤回资金。这看似是一个“稳赚不赔的买卖”(这三个字堪称世上最危险的词之一),于是 SPAC 的组建数量从 2013 年的仅 10 家、2019 年的 59 家,飙升至 2020 年的 248 家和 2021 年的 613 家。其中一些带来了丰厚利润,另一些投资者则拿回了本金和利息。然而,在牛市心理的推波助澜下,这一相对未经检验的创新缺乏质疑声,导致 SPAC 泛滥成灾——无论是能干的还是平庸的组织者,都冲着完成收购(哪怕任何收购)所带来的高额报酬蜂拥而入。

如今,自 2020 年以来通过完成收购(每笔交易均经投资者批准)而“去 SPAC 化”的 SPAC,平均股价仅为 5.25 美元,而发行价为 10.00 美元。这是一个绝妙的例子,说明新鲜事物往往比投资者想象中更不可靠——而这些投资者又一次误信了那根“稳赚不赔”的银子弹。SPAC 的辩护者辩称,这类工具只是将公司上市的另一种途径,但它们的潜在用处并非我所关心。我关注的是,投资者在热潮中多么轻易就拥抱了一项未经检验的创新。

另一个涉及新因素的市场动态也值得一提,因为它恰好印证了“新鲜事物”如何助长牛市:

The raging success of the FAAMGs created a luster that reflected positively on tech stocks in general. Demand soared for stocks in the sector and, as is usual in the investment world, strong demand encouraged and enabled supply. One notable barometer in this case is the attitude toward IPOs from unprofitable companies. Prior to the tech bubble of the late 1990s, IPOs from companies that didn’t make money were relatively rare. They became the norm during the bubble, but their number sunk again thereafter. In the 2020-21 bull market, IPOs from unprofitable companies experienced a big resurgence, as investors easily made allowance for tech companies’ desire to scale and biotech companies’ need to spend on drug trials. If companies with bright futures provide fuel for bull markets, things that are new to the markets can supercharge market excesses. SPACs are a great recent example. Investors gave these newly formed vehicles blank checks for acquisitions on the proviso that investors could get their money back with interest (a) if no acquisition was consummated within two years or (b) if investors didn’t like the acquisition that was proposed. This seemed like a “no-lose proposition” (three of the most dangerous words in the world), and the number of SPACs organized soared from just 10 in 2013 and 59 in 2019 to 248 in 2020 and 613 in 2021. Some produced big profits, and in other cases investors took back their money with interest. But the lack of skepticism surrounding this relatively untested innovation – fueled by bull market psychology – allowed too many SPACs to be created, by competent and incompetent organizers alike who would be highly paid for pulling off an acquisition . . . any acquisition. Today, the average SPAC that de-SPAC-ed since 2020 by completing an acquisition (in each case, with the approval of its investors) is selling at $5.25, versus its issue price of $10.00. This is a good example of a new thing that turned out to be less dependable than investors – who fell once again for a can’t-lose silver bullet – had thought. SPACs’ defenders argue that these vehicles are just an alternative way to take companies public, but their potential usefulness isn’t my concern. I’m focused on how readily investors embraced an untested innovation in hot times. Another dynamic involving novel factors deserves mention, since it exemplifies the way “the new thing” can contribute to bull markets: • • • • • •

Robinhood Markets 在大流行前几年就开始提供股票、ETF 和加密货币的免佣金交易。一旦新冠疫情危机来袭,这鼓励了人们“炒股”,因为赌场和体育赛事因博彩而关闭。慷慨的刺激支票被寄给了数百万未失业的人,这意味着许多人在大流行期间可支配收入增加。像 Reddit 这样的论坛将投资变成了居家隔离人群的社交活动。结果,大量新手散户投资者被在线招募,其中许多人缺乏判断投资价值所需的知识。新人被一位流行的偶像人物煽动,他说“股票只会上涨。”结果,许多科技股和“模因股票”飙升。

Robinhood Markets began offering commission-free trading in stocks, ETFs and cryptocurrencies in the years before the pandemic. Once the Covid-19 crisis hit, this encouraged people to “play the stock market,” as casinos and sports events were closed for betting. Generous stimulus checks were sent to millions who hadn’t lost their jobs, meaning many people saw their disposable income rise during the pandemic. Bulletin boards like Reddit turned investing into a social activity for people shut in at home. As a result, large numbers of novice retail investors were recruited online, many of whom lacked the experience needed to know what constitutes investment merit. Newcomers were stirred by a popular cult figure who said, “stocks only go up.” As a result, many tech and “meme stocks” soared.

最后一个值得讨论的因素是加密货币。例如,比特币的支持者会提到其用途多样,以及相对于潜在需求而言供应有限。另一方面,怀疑者则指出比特币缺乏现金流和内在价值,因此无法合理定价。不论哪一方最终正确,比特币确实具备牛市受益者的一些特征:

The final element worth discussing is cryptocurrency. Proponents of Bitcoin, for example, cite its variety of uses, as well as the limited supply relative to the potential demand. Skeptics, on the other hand, point to Bitcoin’s lack of cash flow and intrinsic value and thus the impossibility of assigning a fair price. Regardless of which side will turn out to be right, Bitcoin satisfies some characteristics of a bull market beneficiary:

它相当年轻(虽然已有 14 年历史,但进入大众视野不过五年)。

它经历了戏剧性的价格暴涨,从 2020 年的 5000 美元一路飙升至 2021 年的 68000 美元高点。

而且,正如加尔布雷思所言,它确实属于前人“没有洞察力去欣赏”的东西。

在所有这几点上,它完全符合加尔布雷思的描述,堪称“被新一代人——往往年轻、且总是极度自信——奉为金融世界中卓越创新发现的产物”。

It’s relatively new (although it has been around for 14 years, it’s been in most people’s consciousness for only five). It enjoyed a dramatic price spike, rising from $5,000 in 2020 to a high of $68,000 in 2021. And it’s certainly something that, per Galbraith, prior generations “do not have the insight to appreciate.” In all these regards, it perfectly satisfies Galbraith’s description of something “hailed by a new, often youthful, and always supremely self-confident generation as a brilliantly innovative discovery in the financial . . . world.”

比特币较 2021 年高点下跌了略超一半,但在数千种已创建的加密货币中,其他币种的跌幅要大得多。

2020 年,FAAMG 股、科技股整体、SPAC、迷因股和加密货币的惊人表现,加剧了市场对它们的狂热,也进一步助长了投资者的普遍乐观情绪。很难想象,在没有任何前所未闻的新事物出现的情况下,会催生一场声势浩大的牛市。“新新事物”以及“这次不一样”的信念,正是反复出现的牛市主题的鲜明例证。

逐底竞赛

另一个在各周期中反复出现的牛市主题,是牛市趋势对投资者决策质量的破坏性影响。简言之,当炽热的乐观情绪取代冷静理智时:

Bitcoin is off a little more than half from its 2021 high, but others among the thousands of cryptocurrencies that have been created have declined much more. The striking performance of the FAAMGs, tech stocks generally, SPACs, meme stocks and cryptocurrencies in 2020 reinforced the craze for them and added to investors’ general optimism. It’s hard to imagine a full-throated bull market arising in the absence of something that’s never been seen or heard before. The “new, new thing” and belief that “this time it’s different” are shining examples of recurring bull market themes. The Race to the Bottom Another bull market theme that rhymes from cycle to cycle is the deleterious impact of bull market trends on the quality of investors’ decision-making. In short, when burning optimism takes over from levelheadedness: • • • •

资产价格上涨,

贪婪相对于恐惧不断膨胀,

害怕错过的情绪取代了害怕亏钱的恐惧,

风险厌恶与谨慎消失殆尽。

asset prices rise, greed grows relative to fear, fear of missing out replaces fear of losing money, and risk aversion and caution evaporate.

必须牢记,正是风险厌恶和对损失的恐惧,才让市场保持安全与理性。上述种种发展往往共同推高市场,驱散了谨慎的调查与深思熟虑,使市场变成一个危险之地。

在我 2007 年的备忘录《逐底竞赛》中,我解释说,当投资者和资本提供者手中资金过多,又急于将资金投入运作时,他们就会对证券和放贷机会出价过猛。这种激烈的竞价压低了预期回报,推高了风险,削弱了安全结构,也收窄了容错空间。

It’s essential to bear in mind that it’s risk aversion and the fear of loss that keep markets safe and sane. The developments listed above typically combine to lift markets, drive out cautious investigation and deliberation, and make the markets a dangerous place. In my 2007 memo The Race to the Bottom, I explained that when there’s too much money in the hands of investors and providers of capital and they’re too eager to put it to work, they bid too aggressively for securities and the chance to lend. Their spirited bidding drives down prospective returns, drives up risk, weakens security structures, and reduces the margin for error. • • •

谨慎的投资者坚守立场,说:“我坚持要 8% 的利息和严格的契约条款。”

她的竞争对手回应:“我愿意接受 7% 的利息,要求的契约条款也少一些。”

最缺乏纪律性的投资者,不愿错失机会,说:“我接受 6% 的利息,不要任何契约条款。”

The cautious investor, sticking to her guns, says, “I insist on 8% interest and strong covenants.” Her competitor responds, “I’ll accept 7% interest and demand fewer covenants.” The least disciplined, not wanting to miss the opportunity, says, “I’ll settle for 6% interest and no covenants.”

这就是逐底竞争。人们常说“最糟糕的贷款往往是在最好的年头放出去的”,道理就在于此。当人们刚从亏损中缓过神来、生怕再受损失时,这种事绝不会发生。美联储对全球金融危机做出大规模应对之后,经济复苏和股市上涨持续了创纪录的十多年,与之相伴的,绝不是什么巧合:

This is the race to the bottom. This is why it’s often said that “the worst of loans are made in the best of times.” This is something that can’t happen when people are smarting from recent losses and afraid of experiencing more. It’s not a coincidence that the record-long 10-plus-year economic recovery and stock market rise that followed the Fed’s massive response to the Global Financial Crisis were accompanied by:

一批亏损企业掀起的上市潮;

垃圾级证券发行量创纪录,其中包括风险较高的 CCC 级债券;

技术和软件等波动性较大行业的企业发债增多,这些债券在行情谨慎时往往遭投资者回避;

并购和杠杆收购的估值倍数不断抬升;以及

风险溢价持续收窄。

a wave of IPOs from money-losing companies; record issuance of sub-investment grade securities, including risky CCC-rated debt; debt issuance from companies in volatile industries such as tech and software that lenders are likely to shun in more cautious times; rising valuation multiples on acquisitions and buyouts; and shrinking risk premiums.

有利的发展态势同样会鼓励人们加大杠杆的使用。杠杆放大收益,也放大亏损,但在牛市里,投资者笃信盈利,无视亏损的可能。在这种环境下,几乎没人觉得有理由不举债——区区利息成本——来放大成功的果实。然而,在周期尾声的高价位上给投资加杠杆,绝非成功之道。形势转差时,杠杆就变成劣势。当投行在周期末期发行债券却找不到买家时,就只能砸在自己手里。债务“压”在银行资产负债表上,往往是预示前景的“矿井金丝雀”。

既然我倚仗的是老掉牙的投资格言,此时正该搬出我心目中关于周期中投资者行为最精辟的那句:“智者开头所为,愚者结尾效仿。”在牛市第一阶段买入的人——彼时悲观情绪弥漫,价格低廉(比如 2008-09 年全球金融危机期间,以及 2020 年新冠疫情初期)——有望以极低风险赚取高额预期回报,前提只有一个:手里有钱,且有胆量花出去。但当牛市升温,丰厚回报助长投资者的乐观情绪时,受到褒奖的品性变成了急切、轻信和冒险。牛市进入第三阶段,新入场者疯狂买入,把市场再托举一阵。谨慎、挑剔、自律,这些最该派上用场的品质,偏偏在这时候被抛到九霄云外。

尤其值得注意的是,心情愉悦、因敢于承受风险而得到回报的投资者,通常会放弃对投资机会的辨别能力。他们不仅认定某些“新事物”的范例必定成功,最终还会得出结论:这个板块里什么都会涨,区分好坏纯属多此一举。

综上所述,“牛市心理”这个词并非褒义。它意味着轻率的行为和高度的风险容忍度,投资者应视其为警讯,而非鼓励。正如沃伦·巴菲特所说:“别人行事越不谨慎,我们行事越该谨慎。”投资者必须认清牛市心理何时占据上风,并施以应有的戒心。

钟摆摆动

牛市不会凭空产生。每轮牛市中的赢家之所以成为赢家,原因很简单:他们的收益背后有一丝真理作支撑。然而,我上面描述的那种乐观情绪往往夸大优点,把证券价格推到过高、因而脆弱的水平。向上的摆动不会永远持续。

在 2016 年 1 月的《沙发上的心理》(On the Couch)一文中,我写道:“现实世界里,事物通常在‘还不错’和‘不太好’之间波动。但在投资世界里,认知常常从‘完美无瑕’摆到‘彻底无望’。”市场里事物被严重做过头的方式,是投资者行为的关键特征之一。牛市期间,投资者认定那些艰难、渺茫、史无前例的事情必定成功。但在情绪不那么高涨的时期,利好的经济消息和“业绩超预期”却无法

Favorable developments also encourage the increased use of leverage. Leverage magnifies gains and losses, but in bull markets, investors feel sure of gains and disregard the possibility of loss. Under such conditions, few can see a reason not to incur debt – with its piddling interest cost – to increase the payoff from their successes. But putting more debt on investments made at high prices late in the up-cycle is no formula for success. When times turn bad, leverage turns disadvantageous. And when investment banks issue late-cycle debt that they can’t place with buyers, they’re stuck with it. Debt “hung” on banks’ balance sheets is often a “canary in the coal mine” with regard to what’s in store. Since I’m relying on time-worn investment adages, it’s appropriate at this point to invoke the one I consider the greatest regarding investor behavior over cycles: “What the wise man does in the beginning, the fool does in the end.” People who buy in stage one of a bull market, when prices are low because of prevailing pessimism (such as during the Global Financial Crisis of 2008-09 and in the early days of the Covid-19 pandemic in 2020), have the potential to earn high prospective returns with little risk: the main prerequisites are money to spend and the nerve to spend it. But when bull markets heat up and good returns encourage investors’ optimism, the traits that are rewarded are eagerness, credulousness, and risk-taking. In stage three of a bull market, new entrants buy aggressively, keeping it aloft for a while. Caution, selectivity, and discipline go out the window just when they’re needed most. Particularly noteworthy is the fact that investors who are in a good mood and being rewarded for risk tolerance typically cease to practice discernment regarding investment opportunities. Not only do investors consider it a certainty that some examples of “the new thing” will succeed, but eventually they conclude that everything in that sector will do well, so differentiating is unnecessary. Because of all the above, the term “bull market psychology” isn’t a positive. It connotes carefree behavior and a high level of risk tolerance, and investors should find it worrisome, not encouraging. As Warren Buffett puts it, “The less prudence with which others conduct their affairs, the greater the prudence with which we should conduct our own affairs.” Investors have to know when bull market psychology is in ascendance and apply the required caution. The Pendulum Swings Bull markets don’t arise out of thin air. The winners in each bull market are winners for the simple reason that a grain of truth underlies their gains. However, the bullishness I’ve described above tends to exaggerate the merits and pushes security prices to levels that are excessive and thus vulnerable. And the upward swing doesn’t last forever. In On the Couch (January 2016), I wrote, “in the real world, things generally fluctuate between ‘pretty good’ and ‘not so hot.’ But in the world of investing, perception often swings from ‘flawless’ to ‘hopeless.’” The way things are seriously overdone in the markets is one of the key characteristics of investor behavior. During bull markets, investors conclude that difficult, unlikely, and unprecedented things are sure to work. But in less ebullient times, favorable economic news and “earnings beats” fail to

刺激买盘,而上涨的价格不再让配置不足的人感到痛苦。于是,我们不再看到人们主动收起怀疑,心理状态转而陷入悲观。

关键在于,投资者几乎能把任何一条新闻解读为利好或利空,取决于新闻的报道方式和他们当时的心情。(下面这幅漫画是我多年来的最爱之一,几十年前就刊登过——看看那对兔子耳朵和电视机的厚度——但配文显然与此时此刻的情形息息相关。)

inspire buying, and rising prices no longer make life painful for people who are underinvested. Thus, we stop seeing the willing suspension of disbelief, and psychology flips to negativism. The key lies in the fact that investors are capable of interpreting virtually any piece of news either positively or negatively, depending on how it’s reported and on their mood. (The cartoon below, one of my all-time favorites, was published many decades ago – check out those rabbit ears and the depth of the TV set – but clearly the caption is relevant to this very moment.)

反映了我前面提到的“从无懈可击到一无是处”的演变过程,当前的主流叙事随时可能逆转。支持牛市的论点在顺境中或许有相当合理的成立概率,但投资者在当时却将其视为铁板钉钉。然而,当论点中的某些缺陷逐渐暴露时,它又被全盘否定为完全错误。

Reflecting the “flawless-to-hopeless” progression I mentioned earlier, prevailing narratives are subject to reversal. While the argument supporting the bull market may have been reasonably likely to hold, investors treated it as ironclad when all was going well. When some of the argument’s flaws come to light, however, it’s dismissed as all wrong. •

在去年那段欢乐时光里,科技牛市派说:“你必须买成长股,因为它们未来几十年的盈利增长潜力巨大。”可如今,经历了一轮大幅下跌后,我们反倒听到这样的声音:“基于未来潜力做投资太冒险了。你必须坚守价值股,因为它们当下价值确定、价格合理。”

同样,在狂热时期,参与亏损公司首次公开募股的人说:“那些报亏损的公司没什么问题。它们花钱扩张规模是合理的。”但在眼下的回调中,很多人又说:“谁会给不赚钱的公司投钱?它们纯粹就是烧钱机器。”

In the happy season (all of a year ago), the tech bulls said, “You have to buy growth stocks for their decades of potential earnings increases.” But now, after a significant decline, we instead hear, “Investing based on future potential is too risky. You have to stick to value stocks for their ascertainable present value and reasonable prices.” Likewise, in the heady times, participants in IPOs of money-losing companies said, “There’s nothing wrong with companies that report losses. They’re justified in spending to scale up.” But in the present correction, many say, “Who would invest in unprofitable companies? They’re just cash incinerators.”

没怎么花时间观察过市场的人可能以为,资产价格完全由基本面决定,但事实绝非如此。资产的价格取决于基本面,以及人们对基本面的看法。因此,资产价格的变化,要么源于基本面的变化,要么源于人们对基本面看法的变化,或者两者兼而有之。公司基本面在理论上受制于

People who haven’t spent much time watching markets may believe that asset prices are all about fundamentals, but that’s certainly not so. The price of an asset is based on fundamentals and how people view those fundamentals. So the change in an asset price is based on a change in fundamentals and/or a change in how people view those fundamentals. Company fundamentals are theoretically subject to

所谓“分析”甚至可能预测。另一方面,对基本面的态度属于心理/情绪层面,不受分析或预测的约束,并且变化速度更快、幅度更大。也有谚语捕捉了这一维度:

something called “analysis” and possibly even prediction. On the other hand, attitudes regarding fundamentals are psychological/emotional, not subject to analysis or prediction, and capable of changing much faster and more dramatically. There are adages that capture this dimension, too: • •

气球泄气远比充气快得多。

事情的发生过程往往比你预想的要漫长,但一旦发生,其速度之快又远超你的想象。

The air goes out of the balloon much faster than it goes in. It takes longer for things to happen than you thought it would, but then they happen much faster than you thought they could.

至于后者,就我的经验而言,我们常常看到正面或负面的基本面变化累积好一阵子,证券价格却毫无反应。但随后会到达一个临界点——无论是基本面还是心理层面的——整堆变化突然在价格上得到体现,有时甚至矫枉过正。

接下来会发生什么?

牛市不会平等对待所有板块。在牛市中,如前所述,乐观情绪最强烈地汇聚在某些特定证券群体周围,比如“新事物”或“超级股票”。这些股票涨幅最大,成为这一时期牛市的标志,并吸引更多买盘。媒体对这些板块关注最多,进一步推波助澜。2020—2021 年,FAAMG 和其他科技股就是这种现象的最佳例证。

不言而喻——但我还是要说——持有大量每轮牛市领涨股的投资者表现非常出色。而那些足够聪明或足够幸运、专门重仓这些板块的基金经理,在乐观情绪盛行期间报告了最高回报,并出现在报纸头版和有线电视节目中。过去我曾说过,我们这一行里,不少人因为连续对了一次就出了名。对那些足够聪明或幸运、超配领涨牛市板块的基金经理来说,这话更要加倍适用。

然而,上涨年份涨幅最大的股票,在下跌年份往往跌幅也最大。这里适用的谚语来自现实世界,但并不因此降低其相关性:“玩刀者死于刀下”;“涨得越高,跌得越重”;“个头越大,摔得越惨”:

As for the latter, in my experience, we often see positive or negative fundamental developments pile up for a good while, with no reaction on the part of security prices. But then a tipping point is reached – either fundamental or psychological – and the whole pile suddenly gets reflected in prices, sometimes to excess. Then What Happens? Bull markets don’t treat all sectors the same. In bull markets, as I discussed earlier, optimism coalesces most powerfully around certain groups of securities, such as “the new thing” or “super stocks.” These rise the most, become emblematic of the bull in this period, and attract further buying. The media pay these sectors the most attention, extending the process. In 2020-21, the FAAMGs and other tech stocks were the best examples of this phenomenon. It goes without saying – but I’ll say it anyway – that investors holding large amounts of the things that lead in each bull market do very well. And fund managers who are smart enough or lucky enough to be dedicated exclusively to those things report the highest returns while optimism prevails and show up on the front page of newspapers and on cable TV shows. In the past, I’ve said our business is full of people who got famous for being right once in a row. That can go double for fund managers who are smart or lucky enough to be overweight the sectors that lead a bull market. However, the stocks that rise the most in the up years often experience the greatest declines in the down years. The applicable adages here are from the real world, but that doesn’t reduce their relevance: “live by the sword, die by the sword;” “what goes up must come down;” and “the bigger they are, the harder they fall”: • • •

一家科技基金 2020 年上涨 157%,从默默无闻一举成名。但 2021 年它亏损 23%,2022 年至今又下跌 57%。2019 年底投入的 100 美元,一年后值 257 美元,但今天只剩 85 美元。

另一家科技基金,波动稍小,2020 年上涨 48%,但此后又下跌 48%。可惜的是,涨 48% 和跌 48% 并不会抵消为零,而是每投入 100 美元净亏 22 美元。

第三家科技基金第一年惊人地上涨 291%,但随后三年分别下跌 21%、60% 和 61%。这四年期初投入的 100 美元,期末仅值 43 美元,相比那不可思议的第一年年末,跌幅达 89%。但等一下:当前这轮繁荣/萧条还没满四年。没错,我引用的结果来自 1999 年至 2002 年,那是上一轮科技泡沫膨胀和破裂的时期。我提这些只是为了提醒大家,当下的表现模式是历史的重演。

One tech fund rose by 157% in 2020, moving from obscurity to fame. But it lost 23% in 2021 and is down another 57% so far in 2022. $100 invested at year-end 2019 was worth $257 a year later, but that’s down to $85 today. Another tech fund, somewhat less volatile, was up by 48% in 2020 but is down by 48% since. Unfortunately, up 48% and down 48% don’t combine to produce zero change, but rather a net decline of $22 per $100 invested. A third tech fund was up a startling 291% in year one, but it fell by 21%, 60%, and 61% in the three years that followed. $100 invested at the beginning of this four-year period was worth $43 at the end, a decline of 89% from the end of that incredible first year. But wait a minute: there haven’t been four years in the current boom/bust. No, the results I cite are from 1999-2002, when the last tech bubble inflated and collapsed. I include them only as a reminder that the current performance pattern is a recurrence.

前面我提到了罗宾汉,也就是免佣金交易的鼻祖。它是 2020 到 2021 年牛市里数字化的典型代表。罗宾汉 2021 年 7 月上市,发行价 38 美元,接下来一周内股价飙到 85 美元。如今只剩 10 美元,不到一年就从高点跌去 88%。

Earlier I mentioned Robinhood, the originator of commission-free trading. It epitomized the role of the digital in the 2020-21 bull market. Robinhood went public in July 2021 at $38, and over the next week, the stock price shot up to $85. Today it’s at $10, an 88% drop from the high in less than a year.

但股指整体表现也没那么糟,对吧?以科技股为主的纳斯达克综合指数 2022 年“仅”下跌 27.4%。这轮牛市的一个特点是,权重最大的大公司股票表现最好,托起了指数。想想这对其他股票意味着什么;纳斯达克 22% 的股票跌幅至少达到 50%。(此处及下文数据截至 5 月 20 日。)

以下是我随手挑的一些知名科技/数字/创新类股票从高点的跌幅。也许其中几只,在它们处于顶峰时,你曾懊悔自己没买:

Salesforce

Carvana

DocuSign

Moderna

Netflix

Shopify

But the equity averages aren’t doing that badly, right? The tech-heavy Nasdaq Composite is “only” down 27.4% in 2022. One of the characteristics of this bull market is that the biggest companies’ stocks – which are the most heavily weighted – have done the best, buoying the indices. Consider what that implies for the rest; 22% of Nasdaq stocks are down at least 50%. (Data here and below are as of May 20.) Here are the declines from the top of some well-known tech/digital/innovation stocks that I picked at random. Maybe there are a few here that, when they were at their peak, you kicked yourself for not having bought: PayPal Beyond Meat Coinbase Salesforce Carvana DocuSign Moderna Netflix Shopify Spotify Uber Zoom

假设你依然相信,市场价格是由一群聪明的投资者基于基本面共识决定的。如果真是这样,那为什么这些股票会跌这么多?而且,你真的相信这些生意的价值在过去几个月里平均缩水了一半以上吗?这种追问会引向我经常思考的另一个问题。在股市波动最剧烈的日子里,比特币常常跟着同向波动。这两者之间有什么基本面理由应该关联吗?国际联动也是如此:日本股市开盘大跌时,欧洲和美国常常跟着跌。有时又像是美国股市领跌,日本跟着走。这些国家的基本面联系真的紧密到足以解释这种同步波动吗?

我对所有这些问题的答案基本都是“不”。共同的线索不是基本面,而是心理。当心理发生重大变化时,所有这些都会受到类似影响。

经验教训

对投资学生来说,一如既往,最重要的不是某个时期发生了什么事件,而是我们能从这些事件中学到什么。从 2020-21 年的趋势中,有很多值得借鉴的东西,这些趋势与之前周期有着相似的韵脚。在牛市中:

Let’s say you still believe market prices are set by a consensus of intelligent investors on the basis of fundamentals. If that’s the case, then why are all these stocks down by such large percentages? And do you really believe the value of these businesses has more than halved on average in the last few months? This line of inquiry leads to something else I think about often. On days when the stock market makes its biggest moves, Bitcoin often moves in the same direction. Is there any fundamental reason why the two should be correlated? The same goes for international links: when Japan starts off the day with a big decline, Europe and the U.S. often follow suit. And sometimes it seems U.S. stocks lead and it’s Japan that falls in line. Are these countries’ fundamentals connected enough to justify co-movement? My answer to all these questions is generally “no.” The common thread isn’t fundamentals: it’s psychology, and when the latter changes significantly, all of these things are similarly affected. The Lessons As always for students of investing, what matters most isn’t what events transpired in a given period of time, but what we can learn from these events. And there’s a lot to be learned from the trends in 2020-21 that rhymed with those in previous cycles. In bull markets: • • •

乐观情绪总是围绕着那些表现极其出色的领域凝聚起来。

当涨势源于心理和价格双双极度低迷的底部时,这种影响最为强烈。牛市心理伴随着无忧无虑和高度风险容忍,因而催生极度激进的行为。承担风险受到回报,而彻底审慎的必要性却被忽视。

Optimism builds around the things that are doing spectacularly well. The impact is strongest when the upswing arises from a particularly depressed base in terms of psychology and prices. Bull market psychology is accompanied by a lack of worry and a high level of risk tolerance, and thus highly aggressive behavior. Risk-bearing is rewarded, and the need for thorough diligence is ignored.

高回报会强化人们对新奇、非常规和乐观前景的信念。当人群对这些事物的价值深信不疑时,往往会得出“价格再高也不为过”的结论。这些影响最终会在它们(连同价格)触及不可持续的水平后逐渐冷却。高企的市场容易受到外部事件的冲击,比如俄罗斯入侵乌克兰。涨幅最大的资产——以及超配这些资产的投资者——往往会遭遇痛苦的逆转。

High returns reinforce belief in the new, the unlikely, and the optimistic. When the crowd becomes convinced of those things’ merit, they tend to conclude “there’s no price too high.” These influences cool eventually, after they (and prices) have reached unsustainable levels. Elevated markets are vulnerable to exogenous events, like Russia’s invasion of Ukraine. The assets that rose the most – and the investors who over-weighted them – often experience painful reversals.

这些主题在我的职业生涯中反复出现过多次。它们无一与基本面发展直接相关,根源多半在于心理层面,而心理的运行方式不太可能改变。正因如此,我确信只要人类参与投资过程,这些现象就会一次次重演。

另外提醒一句,既然市场的大起大落主要由心理驱动,那么市场的走向只有在价格处于荒谬的高位或低位时,才谈得上预测。

These are themes I’ve seen play out numerous times during my career. None of them relates exclusively to fundamental developments. Rather, their causes are largely psychological, and the way psychology works is unlikely to change. That’s why I’m sure that as long as humans are involved in the investment process, we’ll see them recur time and time again. And, as a reminder, since the major ups and downs of the markets are primarily driven by psychology, it’s clear that market movements can only be predicted, if ever, when prices are at absurd highs or lows.
