股票市场的前景

The Outlook for Equities

一段话就能让我开始写备忘录。这次,一句来自《养老金与投资》网站 2 月 4 日文章的话就够了,该文由 FierceFinance 在 2 月 28 日转载:“长期股权风险溢价通常在 4.5% 到 5% 之间。”

我几乎没比投资泛泛之论更讨厌的东西。多年来,比如,那些自称高收益债券市场权威的人常说:“债券违约通常在发行后 2 到 3 年发生。”这话总让我牙根发痒。违约时间可能平均在 2 到 3 年,但除非(1)这也是最常见的时间段(众数),并且(2)不是一个高度波动的参数(我认为它恰恰如此),否则这种泛泛之论毫无用处。

事实上,我喜欢马克·吐温 100 多年前对这类话题的总结:“所有概括都是错的,包括这一条。”我认为大多数投资泛泛之论都跟那个伟大的矛盾修辞“常识”一样无用。

回到股权风险溢价。那篇 FierceFinance 文章开头写着:“在包括美国、英国和荷兰在内的主要市场中,大多数固定收益养老金计划在 2013 年不太可能看到从债券‘大轮动’回股票。”文中包含了不少我认为颇具挑衅性的说法:

即养老金基金确实想减少债券,但通常并不想增持股票(这引出了一个问题:资金会流向哪里,具体来说,除了股票和债券之外的资产类别能合理吸收多少资金),

即据一位顾问称,“人们认识到债券代表低风险资产,因此(计划高管)很难放弃债券转向股票……”(这忽视了一个事实:不存在无论价格如何都算低风险的资产,而且很少有资产在经历多年强劲资金流入后还能真正称得上“低风险”),以及

即“投资者正利用不断上升的股权溢价获取短期战术优势,例如,允许多元资产经理将股票配置比例偏向区间上限。”

所以,我们就到了第三个要点,又回到股权风险溢价这个话题上。

It doesn‟t take much to get me started on a memo. In this case one sentence was enough, in an article from the February 4 online edition of Pensions & Investments, as described by FierceFinance on February 28: “The long-term equity risk premium is typically between 4.5% and 5%.” There‟s little I hate more than investment generalizations. For years, for example, self-styled authorities on the high yield bond market would say “bond defaults typically take place 2-3 years after issuance.” That always set my teeth on edge. The time to default might average 2-3 years, but unless (1) that‟s also the most common time period (the mode) and (2) not a highly variable parameter (which I think it is), that generalization is absolutely useless. In fact, I like the way Mark Twain summed up on the subject more than 100 years ago: “all generalizations are false, including this one.” I consider most investment generalizations as useless as that great oxymoron: “common sense.” Back to equity risk premiums. The FierceFinance article in question led with the sentence, “The „great rotation‟ back into equities from bonds is unlikely to be seen in 2013 among most defined benefit pension funds in major markets, including the U.S., U.K. and Netherlands.” It included a number of what I consider provocative statements: that pension funds do want fewer bonds but generally not more stocks (raising the question of where the money will go, and specifically how much money can responsibly be absorbed in asset classes other than stocks and bonds), that, according to one consultant “There is recognition that bonds represent minimal-risk assets, so it‟s difficult for (plan executives) to abandon bonds in favor of equities. . .” (This overlooks the fact that there‟s no such thing as a minimal-risk asset regardless of price, and few assets that have been the beneficiaries of years of strong cash inflows can really be “minimal-risk”), and “that investors are taking short-term tactical advantage of the rising equity premium by, for example, allowing multiasset managers to drift toward the higher end of the equity allocation range.” So there we are, in the third bullet point, back to the matter of the equity risk premium.

关于股权风险溢价你想知道的一切(以及更多)

股权风险溢价通常被定义为“某只个股或整个股票市场相对于无风险利率所提供的超额回报”(引自 Investopedia)。也就是说,它是股票投资者因承担相应风险而获得的、相对于无风险利率的那部分额外回报。

Everything You Ever Wanted to Know About Equity Risk Premiums (and Much More) The equity risk premium is generally defined as, “the excess return that an individual stock or the overall stock market provides over a risk-free rate.” (Investopedia) Thus it is the incremental return that investors in equities receive relative to the risk-free rate as compensation for bearing the risk involved.

这个词也用来描述股票回报超过债券回报的幅度,同样是对承担额外风险的补偿。(例如,2011 年 8 月 18 日《寻找阿尔法》网站上有一篇文章,题为“股权风险溢价在说什么”,讨论了股票与十年期美国国债的前景比较。)

我对这个词的真正不满——或者说,更准确地说,是对它被使用的方式——跟英语里一个极小的词有关。或者,套用一位美国前总统的话,“这全看‘是’字怎么定义。”

很多人谈论股权风险溢价的存在和大小——甚至他们实际想表达什么——都自以为很清楚,但我觉得没多少人在使用时逻辑一贯或前后一致。我的不满集中在他们给这个词下的定义上,尤其是所用动词的时态(我不纯粹是抠语法)。

最具体地说,我强烈反感现在时的用法,比如那位为《养老金与投资》写稿的作者所说:“长期股权风险溢价通常在 4.5% 到 5% 之间。”这种说法暗示溢价是某种确切存在、金额固定的东西,可以指望未来兑现。

设想一下,假如她说的是“长期股权风险溢价历来在 4.5% 到 5% 之间”。这一改,溢价更像是历史事实,但未来也不再那么可靠(大概本该如此)。

股权风险溢价实际上至少有四种不同定义,我认为:

  1. 股票回报超过无风险利率的历史超额部分。
  2. 过去人们为从无风险资产转向股票而要求的最低增量回报。
  3. 今天人们为从无风险资产转向股票而要求的最低增量回报。
  4. 未来股票回报超过无风险利率的幅度。

这四种用法各不相同,而且重要的是,四种都时不时被用到。我敢肯定,这四种用法常常被混为一谈。显然,选哪种定义,这个词的含义大不相同。在我看来,真正要紧的是第四种:股权投资未来能带来什么回报。也恰恰在这一点上,最不该用“是”这个词,好像风险溢价已经成了既成事实。

The term is also used to describe the extent to which the return on stocks exceeds the return on bonds, again as compensation for bearing incremental risk. (For example, an August 18, 2011 article on the Seeking Alpha website, entitled “What the Equity Risk Premium Is Saying,” discusses the prospects for stocks versus the ten-year U.S. Treasury note.) My real problem with the term – or, more correctly, the way it‟s used – has to do with one of the littlest words in the English language. Or, to paraphrase a former President of the United States, “it all depends on the meaning of the word is.” Many people know what they think they mean when they talk about the existence and magnitude of the equity risk premium – or even what they actually mean – but I don‟t think many are logical or consistent in using it. My complaints surround the definition they apply to the term, and specifically the tense of the verb they employ (I‟m not just being grammatically picky). Most specifically, I strongly dislike the use of the present tense, as exemplified by the writer for P&I: “The long-term equity risk premium is typically between 4.5% and 5%.” This suggests that the premium is something that solidly exists in a fixed amount and can be counted on to pay off in the future. Imagine instead that she had said “The long-term equity risk premium has typically been between 4.5% and 5%.” This makes the premium seem more like a historical fact but also less dependable in the future (probably as it should be). The equity risk premium can actually be defined at least four different ways, I think:

  1. The historic excess of equity returns over the risk-free rate.
  2. The minimum incremental return that people demanded in the past to make them shift from the

risk-free asset to equities. 3. The minimum incremental return that people are demanding today to make them shift away from the risk-free asset and into equities. 4. The margin by which equity returns will exceed the risk-free rate in the future. The four uses for the term are different and, importantly, all four are applied from time to time. And I‟m sure the four uses are often confused. Clearly the import of the term is very different depending on which definition is chosen. The one that really matters, in my opinion, is the fourth: what will be the payoff from equity investing. It’s also the one about which it’s least reasonable to use the word “is,” as if the risk premium is a fact.

股票能给你带来什么?

这四个含义里至少有三个存在问题。只有第一个可以被衡量。关于股票相对债券和现金的历史表现,数据非常丰富。事实上,在 1990 年代,沃顿商学院的杰里米·西格尔教授用翔实的证据证明了股票在长期内总能胜出。当然,随后的十年证明,情况未必始终如此。

现在更有意思了。虽然我们能计算出股票在过去跑赢债券或现金的幅度(前提是你观察的是 2000 年之前的时期),但我不认为这就等于说,投资者按上面第二个定义所要求的风险溢价是多少。如果股票在十年间跑赢了 5%,那并不意味着人们要求股票比债券或无风险资产高出 5% 的回报才肯买入。他们“要求”的可能是更高或更低,只不过最终拿到的是 5%。

What Will Equities Give You? There are problems with at least three of the four meanings. Only number one can be measured. There‟s a lot of data on the historic performance of stocks versus bonds and cash. In fact, in the 1990s Wharton Professor Jeremy Siegel documented to a fare-thee-well that stocks always won out over long periods of time. Of course the subsequent decade proved that didn‟t have to remain the case. Now it gets more interesting. Although we can calculate the amount by which stocks outperformed bonds or cash in the past (assuming you were looking at periods prior to 2000), I don‟t think that‟s the same as saying what risk premium was demanded by investors in the sense of definition number two above. If stocks outperformed by 5% over a ten-year period, that doesn‟t mean people demanded a 5% higher return to buy equities rather than bonds or the risk-free asset. They might have “demanded” more or less. It‟s just that they got 5%.

同理,我们也可以聊聊第三点——人们当下要求的最低回报增量。但(a)你得到的答案取决于你问谁,(b)这些人是否经过深思熟虑也未可知,(c)无论他们怎么说,对最终相对回报的影响可能微乎其微。他们的回答,更多反映的是他们认为自己能拿到什么,而非他们真正在要求什么……或是他们实际能拿到什么。

对今天的投资者而言,要紧的不是股票过去回报如何,也不是股票投资者过去要求什么或自以为现在在要求什么。要紧的是第四种定义——未来相对表现会怎样。最关键的是要认识到,这一点在任何地方都无从查阅。正如爱因斯坦说过的一句我最爱的话:“并非所有重要的东西都能被计算,也并非所有能被计算的东西都重要。”

正如第四点是股票风险溢价最重要的定义,围绕它的那些问题也同样重要。在我看来,人们倾向于把股票风险溢价(以及其他风险溢价)想成类似债券的信用利差。我跟信用利差打了 35 年交道。它是高收益债券投资的全部存在理由。可它与股票风险溢价几乎毫无共同之处。

假设我们要评估为承担某只 B 级高收益债券的信用风险所提供的补偿是否充分。我们计算该债券的到期收益率或提前赎回收益率,再减去同期限国债的到期收益率。结果就是“收益率利差”或“信用利差”。这个利差告诉我们预期的相对回报是多少——并在对照历史利差、其他债券的利差、该债券本身的风险以及同类、风险更低或更高债券的利差之后——判断这只债券是贵了还是便宜了。

现在把同样的流程套到一只股票或整个股票市场上。首先,计算股票的预期回报。哦,对;没错。这根本没法算。或者说有办法,但要求你(a)对每股收益的增长率做出一个无限期的假设,或(b)对若干年的盈利增长率做出假设,还要假设该时期末市场会给每股收益一个什么样的终期市盈率(而这又取决于从那时起直到无穷远的盈利增长率)。换句话说,一个简单的数学计算就能告诉我们债券的承诺回报是多少(尽管不是拿到这笔回报的概率),而要算出股票的未来回报,就得对遥远的未来做出一连串巨大的猜测。这个差异——一言以蔽之——概括了股票与债券投资之间的许多根本区别。

归根结底:既然不可能准确说出某只股票或整个股市会带来多少回报,那同样不可能说出预期股票风险溢价是多少。股票回报历史上超过无风险利率的部分,按第一种定义或许能告诉你答案——相关与否取决于你选哪个时期——但它对另外三种定义一概不置一词……尤其不是第四种:股票回报未来超越无风险利率的幅度。

In a similar vein, we can also talk about number three, the minimum return increment people are demanding today. But (a) the answer you come up with will depend on whom you ask, (b) they may or may not have given it rigorous thought, and (c) whatever they say is likely to have little impact on what relative returns turn out to be. Their answer is likely to tell you more about what they think they‟ll get than about what they‟re actually demanding . . . or what they will get. What matters for today‟s investor isn‟t what stocks returned in the past, or what equity investors demanded in the past or think they‟re demanding today. What matters is definition number four, what relative performance will be in the future. The most important thing of all is to realize that this can’t be read anyplace. As Einstein said, in one of my favorite quotes, “Not everything that counts can be counted, and not everything that can be counted counts.” Just as number four is the most important definition of the equity risk premium, the questions surrounding it are also significant. In my view, people tend to think of the equity risk premium (and other risk premiums) like credit spreads on bonds. I‟ve been dealing with credit spreads for 35 years. They are the entire raison d'être for high yield bond investing. And they have almost nothing in common with the equity risk premium. Let’s say we want to assess the adequacy of the reward being offered for bearing the credit risk of a given B-rated high yield bond. We compute the yield to maturity or yield to call on the bond and subtract from it the yield to maturity on a Treasury security of the same duration. The result is the “yield spread” or “credit spread.” That spread tells us what the prospective relative return is and – when assessed in the light of historic spreads, the spreads on other bonds, the riskiness of the bond in question, and the spreads on other bonds of similar, lesser or greater riskiness – whether the bond is rich or cheap. Now let’s apply the same process to a stock, or the stock market. First, compute the prospective return on the stock. Oh yeah; right. There’s no way to do that. Or rather there is, but it requires one to either (a) make an assumption about the growth rate of earnings per share to infinity or (b) make an assumption about the growth rate of earnings for a number of years and also the terminal p/e ratio that the market will apply to e.p.s. at the end of that period (which in turn will be a function of the growth of earnings from then to infinity). In other words, a simple mathematical calculation will tell us exactly what the promised return on a bond is (albeit not the probability that it will be received), while coming up with the future return for a stock requires making some massive guesses about the faroff future. That difference – in a nutshell – encapsulates a lot of the fundamental difference between investing in stocks and bonds. The bottom line: given that it‟s impossible to say with any accuracy what return a stock or the stock market will deliver, it‟s equally impossible to say what the prospective equity risk premium is. The historic excess of stock returns over the risk-free rate may tell you the answer according to definition number one, with relevance depending on which period you choose, but it doesn’t say anything about the other three . . . and especially not number four: the margin by which equity returns will exceed the risk-free rate in the future.

再次呼吁反直觉思维

投资的许多要义都反直觉。低质量资产可能比高质量资产更安全。资产越受推崇(因而价格越高),风险反而越大。自以为知道某事,比承认自己不知道,可能蕴含更多风险。这种反直觉性是我最钟爱的主题之一。

Another Call for Counter-Intuitiveness Many of the important things about investing are counterintuitive. Low-quality assets can be safer than high-quality assets. Things get riskier as they become more highly respected (and thus appreciate). There can be more risk in thinking you know something than in accepting that you don‟t. This counterintuitiveness is a favorite theme of mine.

这个主题在讨论股本风险溢价时尤其重要,特别是 P&I 对这个术语的使用。我对他们的说法“长期股本风险溢价通常在 4.5% 到 5% 之间”极为不满。那可能是它“过去是”或“一直是”的水平,但并不能告诉我们它“现在是”或“将来会是”什么。我们知道不能从过去推断债券或无风险资产的回报;过去五年的利率变化当然意味着,投资这些资产的人未来几年能获得的回报将远低于过去。那么,我们有可能知道从股票中能获得什么吗?或者股票相对于债券或无风险利率的表现?显然不能。因此,我认为说风险溢价“是”多少是危险的误导。这个话题就说到这里吧。

接着看第一页最后一条要点,它提到“不断上升的股本溢价”。文章从第一种定义——历史表现更优——的角度讨论了股本风险溢价具有吸引力的理由,因为它接着指出,在截至 2013 年 1 月 31 日的六个月里,股票跑赢债券的幅度异常之大(罗素 3000 指数上涨 11.23%,而巴克莱美国综合债券指数下跌 0.29%)。但六个月的出色表现能说明股本溢价在上升吗?它们能告诉我们关于未来的任何事情吗?

第一个问题的答案取决于你遵循的是哪种定义。当然,数据告诉我们相对表现如何(例如 2012 年是个好年头,标普 500 指数上涨约 16%,而无风险利率接近零)。按照这种定义,股本风险溢价当然处于历史分布的最好区间。但它对投资者过去或当前要求的回报几乎没有说明。它又能说明继续跑赢的前景吗?

在我看来,答案很简单:回报越好,未来表现好的可能性就越低——在其他条件相同的情况下。一般来说,我认为一项资产在其存续期内有既定的回报潜力总量。其回报的基础来自产生现金流的能力。在这个基数上,如果资产被低估,可以预期升值到公允价值,我们就应加上额外的回报潜力;如果被高估,可以预期下跌到公允价值,我们则应降低对其回报潜力的看法。

所以——再次强调,在其他条件相同的情况下——当一项资产的年度回报超过其产生现金流(或现金流增长)的比率时,升值超过现金流相关部分的部分,应被视为要么减少其低估幅度(从而减少可预期的升值),要么增加其高估程度(从而增加可能的价格下跌)。最简单的例子是一只 5% 的债券。假设一只票息 5% 的债券在低于面值的某个价格上,其剩余期限内的预期回报(或到期收益率)为 7%。如果这只债券在接下来十二个月里回报 15%,那么其剩余期限内的预期回报将低于 7%。一个高于趋势的年份从剩余的潜力中借走了一部分。数学在债券上最简单(向来如此),但如果你持有股票、公司或产生收入的房地产,原理是一样的。

换句话说,升值速度超过现金流增长速度,就是把本来可能在未来发生的升值提前兑现到了当下。或者用沃伦·巴菲特的话说:“当人们忘记公司利润不太可能每年增长超过 6% 时,他们往往会陷入麻烦。”我不认为他对 6% 有什么特别的用意,而是提醒人们:当资产升值速度快于其价值增长的速度时,这不仅是意外之财,也是警示信号。

让我们看看 1990 年代,那是个充满股票教训的十年。截至 1990 年,股票的历史回报率为 9% 或 10%,因此人们对股票的态度总体上是积极的,预期未来几十年会重复 9% 到 10% 的回报。但 90 年代在经济增长、企业表现、技术和生产率提升、利率下降、低通胀以及世界相对和平(以及关于信贷好处的天真乐观)方面是个有益的时期——

And the theme is importantly at work with regard to the equity risk premium, and especially P&I‟s use of the term. I take great issue with their statement “The long-term equity risk premium is typically between 4.5% and 5%.” That may be what it “was” or “has been,” but it doesn’t tell us anything about what it “is” or “will be.” We know we can‟t extrapolate returns on bonds or the risk-free asset from the past; certainly changes in interest rates over the last five years mean investors in these things will enjoy far lower returns in the years ahead than they used to. So then is it possible to know what we will get from equities? Or from equities relative to bonds or the risk-free rate? Clearly not. Thus I think it’s dangerously misleading to say what the risk premium “is.” That‟s probably enough on this subject. Let‟s move on to the final bullet point on page one and its reference to “the rising equity premium.” The article discusses the case for an attractive equity risk premium in terms of definition number one – historically superior performance – since it goes on to point out that stocks outperformed bonds by an unusually large margin in the six months ended January 31, 2013 (11.23% for the Russell 3000 versus -0.29% for the Barclays Capital U.S. Aggregate Bond Index). But do six months of good performance say anything about a rising equity premium? And do they tell us anything at all about the future? Well, the answer to the first question lies in which definition you‟re following. Of course the data tells us what the relative performance was (and 2012 was a great year, for example, with the S&P 500 up roughly 16% while the risk-less rate was close to zero). An equity risk premium defined this way is certainly in the best part of the historic distribution. But it tells us little about investors‟ past or present demanded returns. And what does it say about the prospects for continued outperformance? To me, the answer is simple: the better returns have been, the less likely they are – all other things being equal – to be good in the future. Generally speaking, I view an asset as having a certain quantum of return potential over its lifetime. The foundation for its return comes from its ability to produce cash flow. To that base number we should add further return potential if the asset is undervalued and thus can be expected to appreciate to fair value, and we should reduce our view of its return potential if it is overvalued and thus can be expected to decline to fair value. So – again all other things being equal – when the yearly return on an asset exceeds the rate at which it produces cash flow (or at which the cash flow grows), the excess of the appreciation over that associated with its cash flow should be viewed as either reducing the amount of its undervaluation (and thus reducing the expectable appreciation) or increasing its overvaluation (and thus increasing the price decline which is likely). The simplest example is a 5% bond. Let‟s say a 5% bond at a given price below par has a 7% expected return (or yield to maturity) over its remaining life. If the bond returns 15% in the next twelve months, the expected return over its then-remaining life will be less than 7%. An above-trend year has borrowed from the remaining potential. The math is simplest with bonds (as always), but the principle is the same if you own stocks, companies or income-producing real estate. In other words, appreciation at a rate in excess of the cash flow growth accelerates into the present some appreciation that otherwise might have happened in the future. Or to paraphrase Warren Buffett, “when people forget that corporate profits are unlikely to grow faster than 6% per year, they tend to get into trouble.” I doubt he intended anything special about 6%, but rather a reminder that when assets appreciate faster than the rate at which their value grows, it isn‟t just a windfall but also a warning sign. Let‟s take a look at the 1990s, a decade full of lessons about equities. As of 1990, the historic return on equities stood at 9% or 10%, and for that reason attitudes toward them were generally favorable, with that 9-10% return expected to repeat in future decades. But the ‟90s were a salutary period in terms of economic growth, corporate performance, technological and productivity gains, declining interest rates, low inflation and relative peace in the world (as well as naïve optimism regarding the benefits of a credit-

支撑着扩张,电子商务企业的盈利潜力,以及股票收益能够长期持续的程度。结果,这十年间股票年均回报率达到 20%。

投资者作何反应?他们调高了预期。我相信到 2000 年,业界对未来股票回报的共识已从 9%—10% 的区间升至 11%。历史上最高的十年回报让人确信,好年头还在后面。几乎没人担心 1990 年代的非凡回报可能透支了 2000 年代(事后看来确实如此)。于是,就在股价攀上此后十多年都未能再见的高位时,债券却被抛售,以便把股票配置比例推到历史峰值。

我读那篇《养老金与投资》文章时,看到的是“股权风险溢价正在上升”这样的说法,却很少看到为什么股票未来会比过去表现更好的理由(甚至没具体提是比哪个过去更好)。这是外推,还是分析?两者截然不同。

fueled expansion, the profit potential of e-commerce companies, and the extent to which equity gains could be perpetuated). As a result, equity returns averaged 20% per year over the decade. What was investors’ response? They ratcheted up their expectations. I believe by 2000 the professional consensus for future equity returns had risen from the 9-10% range to 11%. A decade of the highest returns in history had convinced people that more good years lay ahead. Few people seemed concerned that the extraordinary returns of the 1990s might have borrowed from the 2000s (as certainly seems to have been the case in retrospect). As a result, just when stock prices were reaching levels they wouldn‟t see again for more than a decade, bonds were being dumped so that equity allocations could be expanded to all-time highs. When I look at the P&I article, I see a statement that the equity risk premium is on the rise, but not a lot of reason why equities will do better in the future than they have in the past (or even specific mention of which past they‟ll do better than). Extrapolation or analysis? They’re two very different things.

当今股票估值

《FierceFinance》之所以只用寥寥数语就激起我写下这份备忘录,根本原因在于我对股票及其当前估值积压了大量想法。接下来的篇幅将专门讨论这些。

颇具讽刺意味的是,尽管我前面大加挞伐,主张不应过度看重股权风险溢价,但当前支持股票的最有力论据之一恰恰围绕其相对盈利能力。鉴于量化股票预期回报的难度,评估其相对债券或无风险资产的价值,通常最好通过比较收益率来完成。

由于多数公司仅将盈利的较小比例作为股息派发,股息率严重低估了公司为股东赚钱的能力,也就低估了股价上涨的潜力。衡量股票长期潜力更好的指标或许是“盈利收益率”。盈利收益率是市盈率的倒数,即市盈率的倒数:盈利除以价格。要判断相对价格吸引力,把股票的盈利收益率与债券收益率(或无风险利率)作比较,并非不合理。

让我们回顾几个数据点:

若二战后股票的平均市盈率约为 16 倍(对应盈利收益率约为 6.25%),且我猜测“正常”无风险利率为 3%,那么我们得到的历史收益率差——可以称之为股权风险溢价,按此定义——为 3.25%(6.25% 减 3.00%),即 325 个基点。两者收益率之比为 6.25%/3.00%,即 2.08 倍。

2000 年高点时,标普 500 指数的市盈率接近 32 倍(对应盈利收益率约 3.12%),而 30 天期国库券利率可能为 2%。彼时收益率差或股权风险溢价仅为 1.12%(3.12% 减 2.00%),即 112 个基点,两者之比仅 3.12%/2.00%,即 1.56 倍。换言之,股票相对于固定收益资产提供的回报不足,这正是此后十三年股票表现如此糟糕——无论绝对表现还是相对债券——的主要原因。

Valuing Stocks Today The underlying reason it took so little from FierceFinance to get me going on this memo is that I had a lot of pent-up thoughts about equities and their current valuation. That‟s what the following pages will be spent on. Ironically given the extent to which I railed above about limiting the importance attached to the equity risk premium, some of the strongest arguments for stocks today surround their relative earning power. In view of the difficulty in quantifying the prospective returns on stocks, appraising their value relative to bonds or the risk-free asset is often best done through comparing their yields. Since most companies pay out a modest percentage of their earnings, dividend yields greatly understate companies‟ ability to earn money for their shareholders, and thus for their stocks to appreciate. A better measure of stocks‟ long-term potential may be found in their “earnings yield.” The earnings yield is the reciprocal of the p/e ratio: the e/p ratio or ratio of earnings to price. To gauge relative priceattractiveness, it isn‟t unreasonable to compare the earnings yield on a stock against the yield on a bond (or against the risk-free rate). Let‟s review a few data points: If the post-WWII average p/e ratio on equities was something like 16 (for an e/p ratio of 1/16, or an earnings yield of about 6.25%) and if I guess at a “normal” risk-free rate of 3%, we get a historic yield differential – we might call it the equity risk premium, defined this way – of 3.25% (6.25% minus 3.00%), or 325 basis points. The ratio between the yields was 6.25%/3.00%, or 2.08x. At the high in 2000, the p/e ratio on the S&P 500 was more like 32 (for an e/p ratio of 1/32, or an earnings yield of 3.12%), and the 30-day T-bill rate was probably 2%. In that case the yield differential or equity risk premium was a skimpy 1.12% (3.12% minus 2.00%), or 112 basis points, and the ratio of the two was only 3.12%/2.00%, or 1.56x. In other words, stocks didn‟t offer enough relative to fixed income, and that‟s the main reason why they‟ve performed so poorly – both in absolute terms and relative to bonds – over the thirteen years since.

我们现在处于什么位置?标普 500 指数的市盈率回到了大约 16 倍,这意味着盈利收益率再次达到了 6.25%。我将采用 30 天期国库券的利率 1.00%(实际上它更接近于零,但一个接近无穷大的收益率比率将没有意义)。这样我们得到了收益率差为 5.25%(6.25% 减去 1.00%),即 525 个基点,以及收益率为 6.25%/1.00%,即 6.25 倍。那么,让我们来总结一下:

Where are we today? The p/e ratio on the S&P 500 is back to about 16, meaning the earnings yield is 6.25% once again. I‟ll use a 30-day T-bill rate of 1.00% (it‟s actually closer to zero, but a yield ratio approaching infinity wouldn‟t be meaningful). That gives us a yield differential of 5.25% (6.25% minus 1.00%), or 525 basis points, and a yield ratio of 6.25%/1.00%, or 6.25x. So let‟s recap:

当然,当前的收益率比较对股票极为有利。事实上,这是近百年来最有利的时机之一(可能仅逊于 1980 年代初,当时标普 500 指数的市盈率跌至个位数中段)。但这就能说明全部问题吗?绝非如此;事情哪有那么简单,尤其是在投资世界里。基于收益率比较来支持股票的观点,其问题在于,目前股票在这方面的吸引力大多源于利率的低企。几乎所有人都知道,(a)由于央行刺激经济的努力,利率人为地偏低,(b)在中期某个时点,利率会显著上升。若是如此,利率上升将使股票的吸引力下降(假设其他条件不变,但实际上并非如此——见下文)。

Certainly the yield comparison is highly favorable for stocks today. In fact it‟s one of the best in the last century (probably barring only the early 1980s, when the p/e ratio on the S&P 500 fell to mid-single digits). Is that the whole story? It never is; nothing‟s that simple, especially in the world of investing. The problem with basing a pro-equities argument on the yield comparison is that most of equities’ current attraction on that basis comes from the lowness of interest rates. Just about everyone knows (a) interest rates are artificially low because of central banks’ efforts at stimulus and (b) rates will be considerably higher at some point in the intermediate term. In that case, rising rates would render stocks less attractive (all other things being equal, but they‟re not – see below).

股票的其他利与弊

看待估值的方式有很多种,当前关于股票的辩论中也涉及诸多要素。以下列举其中几点(为求完整,我先重申上述观点):

标普 500 指数的盈利收益率与无风险利率或债券收益率之间的差距——以及两者的比率——让股票看起来极为便宜。利好

这些相对估值参数的吸引力高度依赖于利率保持在低位。利空(或利好程度减弱)

与二战后的正常市盈率相比,当前股价相对于未来一年预期盈利的倍数处于平均水平至略低水平。利好

罗伯特·席勒的周期调整市盈率正受到越来越多的关注,该指标指向估值充分而非合理。利空

可以说,未来几年的盈利增长将慢于二战后几十年间的水平。因此,在变化的环境下,战后的估值常态过高,应予以折价。利空

盈利前景受到不确定的宏观环境制约,包括重启增长的挑战以及联邦赤字的严峻预判。这些问题可能不易解决。利空

在支撑盈利高企——从而让股票显得有吸引力——的因素中,包括历史上最高的利润率水平之一。如果利润率回归正常水平,那么

The Other Pros and Cons of Equities There are many ways to view valuation, and many elements in the current debate over equities. Here are a few of them (I‟ll start by reiterating the above for the sake of completeness): The differential between the S&P earnings yield and the risk-free rate or the yields on bonds – and their ratio – makes stocks look extremely cheap. PRO The attractiveness of these relative valuation parameters is highly dependent on interest rates staying low. CON (or LESS PRO) Relative to normal post-WWII p/e ratios, stock prices are average to slightly low as a multiple of projected earnings for the year ahead. PRO Robert Schiller‟s cycle-adjusted p/e ratios are gaining increased attention, and they suggest full rather than fair valuations. CON Arguably earnings growth in the years ahead will be slower than that which prevailed in the decades following WWII. Thus the post-war valuation norms are too high under the changed circumstances and should be discounted. CON The outlook for earnings is restrained by the questionable macro environment, including the challenges in restarting growth and the dire prognosis for the federal deficit. These problems may not be easily solved. CON Among the things keeping earnings high – and thus making stocks seem attractive – are some of the highest profit margins in history. If profit margins were to move toward normal levels, this

这些因素会拉低盈利,要么拖累股价下行,要么推高市盈率,从而降低股票的吸引力。反对

企业现金储备高企,这暗示着某种组合:安全性、回购股票的潜力,以及可能的股息上调。这些对股东都是好事。支持

投资者对股票的态度依然冷淡(见下文)。支持

然而,标普 500 指数去年上涨 16%,今年迄今又涨了 10%,所以不能说股票被忽视了,或者说人们的态度还深陷低迷。反对

投资者态度的角色

我在《似曾相识》(2012 年 3 月 19 日)中对此话题已详细讨论过。我不打算再拖你过一遍,但我会把一年前那份备忘录的部分内容抄过来:

……人们一直在认输离场,抛售股票。其他东西走红,吸引了原本投在股票上的资金。共同基金投资者已把注意力转向别处……股票经历了整整十年,绝对回报微乎其微,实际回报还是负的……它们面对一连串负面因素,看不到任何真正的缓解可能……

这些负面因素对普通投资者来说一目了然。从中他得出负面结论。但那些运用逻辑和洞察力,而不是只看表面和情绪的人,看到的却截然不同。

他看到的是一个不受宠的资产类别。他看到股票已便宜了十年——一旦从回报中扣除股息,尤其当价格相对盈利来看时。他看到证券的定价低于其背后资产本身的价值。他看到资本外流,这非但不是负面——反而压低了价格,一旦资金流向逆转,就可能引发强劲反弹。最重要的是,他看到的是一个没有任何乐观情绪注入的资产类别……

关于前面几段,值得注意的一点是,我一年前写这些时,并不是为了描述当时市场状况。相反,我试图捕捉的是 1982 年的情形,当时《商业周刊》杂志封面故事高呼“股票之死”。我的意思是,1982 年,过于悲观的投资者死盯着股票持续萎靡的理由,而恰恰就在这时,史上最猛烈的股市飙升正蓄势待发。

……当某样东西朝一个方向持续一阵子,人们越来越相信它会永远如此……往往就在反转可能性增大之际。这正是“股票之死”最大的缺陷。外推者刚对股票认输离场,而恰恰是反着来的投资者转为乐观的好时机。

而且永远都会是这样。

would bring down earnings, either taking stock prices down with them or lifting p/e ratios and thus reducing stocks‟ attractiveness. CON Corporate cash hoards are high, implying some combination of safety, potential for stock buybacks, and possible dividend increases. These are all good for shareholders. PRO Investor attitudes toward stocks remain tepid (see below). PRO However, with the S&P 500 up 16% last year and 10% so far this year, it can‟t be argued that stocks have been overlooked and or that attitudes towards them are still mired in the doldrums. CON The Role of Investor Attitudes I covered this subject at length in “Déjà Vu All Over Again” (March 19, 2012). I‟m not going to drag you through it again, but I will copy over parts of that memo from a year ago: . . . 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. . . . Stocks have gone through a decade in which their absolute return was negligible and their real return was negative. . . . They face a litany of negatives, without any real possibility of relief . . . 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. . . . The thing to notice about the preceding paragraphs is that when I wrote them a year ago, I didn’t do so to describe then-current market conditions. Rather, I was trying to capture conditions as they were in 1982, when BusinessWeek magazine carried a cover story trumpeting “The Death of Equities.” My point was that in 1982, overly negative investors were fixated on the reasons for continued lethargy on the part of stocks, just when the scene was set for the greatest upsurge in stock market history. . . . 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.

我去年并不认为低估程度能与 1982 年相提并论,但我确实觉得两者在性质上颇为相似。没有什么比过度的悲观情绪——或者至少是过度的漠不关心——更能为行情反转铺平道路了。而这就是我在去年股市中感受到的氛围,紧随十二年的低迷之后。因此,我认为 2012 年全球股市迎来出色表现并非偶然。

许多条件仍然相似……同样是在性质上。股票型共同基金仅见温和的净流入,尽管资金流出已停止。即使股价已上涨,股票估值依然不算高。许多机构的股票配置比例远低于过去五十年的平均水平,而且没有人急于提高这一比例。换句话说,我可以放心地说,人们对股票的态度仍以相对冷淡和漠然为特征。

这种情况当然可能发生转变。一旦转变,影响将相当显著。而最可能推动转变的因素是什么?未必需要华盛顿达成“大妥协”来解决国家的财政问题,也未必需要全球经济增长突然复苏,或者下一代 iPhone 的问世。只需股市再有一两年的好光景,加上投资者心理从“股票除了延续‘失去的十年’之外恐怕难有作为”转向“嘿,我怕自己仓位不够,赶不上下一轮牛市了。”

上涨的动力可以来自从害怕亏钱到害怕错过机会的心理转变。当情绪温和、仓位偏低时,不需要太多推力就能启动行情。

I didn‟t think last year that the extent of the undervaluation was anywhere as great as it had been in 1982, but I did think the conditions were similar in kind. Nothing sets the stage for an upturn as well as excessive negativism – or at minimum excessive disinterest. And that‟s what I sensed in the stock market last year, following on the heels of a twelve-year malaise. Thus I don‟t consider it a freak occurrence that stocks all around the world went on to have an excellent year in 2012. Many conditions remain similar . . . again, in kind. Equity mutual funds are seeing only modest inflows, albeit the outflows have stopped. Even though they’ve appreciated, stocks still aren’t highly valued. Many institutions have allocations to equities that are well below the average of the last fifty years, and no one’s rushing to move them up. In other words, I’m comfortable saying attitudes toward equities are characterized by relative disinterest and apathy. This is certainly something that can turn. If it turns, it can have a significant impact. And what is most likely to turn it? It won‟t necessarily take a “grand bargain” in Washington to solve the nation‟s fiscal problems, or a sudden rebirth of economic growth worldwide, or the invention of the next iPhone. All that‟s required is another good year or two for stocks and a switch in investor psychology from “stocks are unlikely to do anything but extend the „lost decade‟ ” to “hey, I‟m afraid I might not be positioned adequately to participate in the next bull market.” A move upward can be powered by a switch from the fear of losing money to the fear of missing opportunity. When attitudes are moderate and allocations are low, it doesn’t take much.

1970 年代中期,我有幸撞上了早年那些启智良言中的一条,它对我的投资教育功不可没。讲的是牛市三阶段:第一阶段,少数有远见的人开始相信情况会好转;第二阶段,多数投资者意识到改善确实在发生;第三阶段,所有人都确信好日子会永远持续下去。

在 2008 年 3 月(金融危机见底前几个月)写的《潮水退去》里,我把同样的思路用到了反面——熊市三阶段:第一阶段,只有少数谨慎的投资者意识到,尽管 prevailing 看涨情绪高涨,事情不会永远顺风顺水;第二阶段,多数投资者意识到情况在恶化;第三阶段,所有人都坚信情况只会更糟。

事后看,某个时间点发生了什么总是一清二楚。现在不难说 2007 年第二季度就是牛市的第三阶段:当时没人想得出怎么亏钱。而 2008 年第四季度(信贷市场)和 2009 年第一季度(股市),我们无疑处在熊市的第三阶段:多数人以为金融体系要崩了,价格已经腰斩的证券只能再腰斩一次。

但研究市场历史,只有当我们学会用它来评估当前状况、而不是复盘过去时,才能成为更好的投资者。一年前写《似曾相识再来》时,我感觉股市处于牛市第一阶段。此前经历糟糕透顶,持续了太久……

In the mid-1970s I was fortunate to happen upon one of the first of the time-worn pearls of wisdom that contributed so much to my education as an investor. It described the three stages of a bull market: the first, when a few forward-looking people begin to believe things will get better, the second, when most investors realize improvement is actually underway, and the third, when everyone‟s sure things will get better forever. In “The Tide Goes Out,” written in March 2008, several months before the lows of the financial crisis, I applied the same thinking to the converse – the three stages of a bear market: the first, when just a few prudent investors recognize that, despite the prevailing bullishness, things won‟t always be rosy, the second, when most investors recognize things are deteriorating, and the third, when everyone‟s convinced things can only get worse. Hindsight always makes it clear what was going on at a particular point in time. It‟s a snap now to say the second quarter of 2007 marked the third stage of a bull market: no one could think of a way to lose money. And in the fourth quarter of 2008 (for credit) and the first quarter of 2009 (for equities), we were certainly in the third stage of a bear market: most people thought the financial system was about to collapse, and securities that had halved in price could do nothing but halve again. But the study of market history only makes us better investors if it teaches us how to assess conditions as they are, rather than in retrospect. When I wrote “Déjà Vu All Over Again” a year ago, it was my feeling that equities were in the first stage of a bull market. Experience had been so bad for so

当时市场长期低迷,投资者兴趣冷淡到极点,几乎没人相信股票还能再次走牛。正是这种低预期,加上基本面和心理层面出现小幅改善,推动标普 500 指数在备忘录写就后的一年里回报率约 13%。如今,基本面环境有所好转,投资者整体心态也更乐观,股价则上涨了不少。没人会再说改善的可能性尚未被充分认识——若真如此,那还停留在第一阶段。我认为,改善的存在已被广泛接受,但这种接受既未到极为普遍的程度,也没出现过度反应。因此,我会说我们正处于第二阶段的前半程。悲观者已不再主导市场价格,但漫不经心的乐观者显然也尚未接管局面。

long – and the level of disinterest was so high – that only a few investors thought equities could ever catch on again. Those low expectations, when combined with modest fundamental and psychological improvement, gave the S&P 500 a return of about 13% over the year since that memo was written. So now we have a somewhat improved fundamental environment, a generally more optimistic group of investors, and stock prices that are a fair bit higher. No one should say the likelihood of improvement is entirely unrecognized today, as would have to be the case for this to still be stage one. I think the existence of improvement is generally accepted, but that acceptance is neither extremely widespread nor terribly overdone. Thus I’d say we’re somewhere in the first half of stage two. Pessimists no longer control market prices, but certainly neither have carefree optimists taken over.

一轮大轮动?也许吧……也许未必。如今,专家和媒体动不动就爱给正在发生或“人人都知道”即将发生的事情贴上俏皮的标签——通常刚好够写个标题或上新闻头条。我不知道会不会出现大轮动。见鬼,我甚至不知道它会不会发生。但我喜欢列出正反两面,试着把它们放到正确的视角里审视,就像我喜欢戳穿那些过度概括和想当然的断言一样。

当然,光这么做还不够。我觉得自己应该表明立场。因此,我愿意想象未来几年的股市表现会带来惊喜,相对我认为目前普遍预期的每年 6% 左右的收益而言。

如果我错了——如果资金没有从固定收益转向股票——我也并不会因为没抢购收益率为零的短期国库券或保证 2.0% 收益率的 10 年期国债而懊悔不已。当投资者态度温和、配置比例偏低时——我觉得目前股市就是这种情况——投资出大错的可能性很小。而当利率处于历史最低水平时,只有出现通缩、萧条或灾难,才会让不投资国债和高等级债券成为严重的失误。

A great rotation? Maybe . . . or maybe not. Nowadays pundits and the media are quick to come up with cute labels – usually just the right size for a headline or sound bite – to describe things that are taking place or that “everyone knows” are just around the corner. I don’t know whether it’s going to be great. Heck, I don’t even know if it’ll happen. But I like to enumerate the pros and cons and try to put them in perspective, as much as I like skewering excessive generalizations and pat pronouncements. Of course, doing that isn‟t enough. I feel I should come down on one side or the other. Thus I’m quite comfortable imagining a few years of equity performance that provide a pleasant surprise relative to what I think is the prevailing expectation of 6% or so per year. And if I‟m wrong – if there is no rotation from fixed income to stocks – I‟m not that worried that I‟ll end up with great regret over having failed to pile into T-bills yielding zero or the 10-year note guaranteeing 2.0%. When attitudes are moderate and allocations are low, like I feel is currently the case with equities, there‟s little likelihood of investing being a big mistake. And when interest rates are among the lowest in history, it would take deflation, depression or calamity to make failing to invest in Treasurys and high grade bonds a serious omission.
