M&M 论估值 迈克尔·J·莫布森 因为真理的大敌往往不是谎言——那些蓄意、编造、不诚实的谎言——而是神话——那些持久、有说服力、却脱离现实的神话。我们常常固守前人的老生常谈。我们把所有事实都塞进一套预制好的解读框架里。我们享受意见带来的舒适,却不愿忍受思考带来的不适。

M&M on Valuation Michael J. Mauboussin For the great enemy of truth is very often not the lie—deliberate, contrived and dishonest—but the myth—persistent, persuasive, and unrealistic. Too often we hold fast to the clichés of our forebears. We subject all facts to a prefabricated set of interpretations. We enjoy the comfort of opinion without the discomfort of thought.

市盈率(P/E 倍数)是华尔街最流行的估值指标。然而,多数投资者并不真正明白市盈率倍数隐含了公司未来怎样的财务表现,也不清楚公司的市盈率倍数随时间推移可能发生怎样的变化。

• Price-earnings (P/E) multiples are by far the most popular valuation metric on Wall Street. Yet most investors don’t clearly understand what a price-earnings multiple implies about a company’s future financial performance, or how a company’s price-earnings multiple will likely change over time.

我们提供了一座分析桥梁,将估值倍数与扎实的经济推理连接起来。

• We offer an analytical bridge between valuation multiples and sound economic reasoning.

• 增长在估值中的作用,完全取决于一家公司的资本回报率。

• The role of growth in valuation is completely contingent on a firm’s return on capital.

• 投资者的关键在于预判预期的修正。

• The key for an investor is to anticipate expectation revisions.

引言

市盈率(P/E)是华尔街迄今为止最流行的估值指标。一项近期学术研究发现,99.1% 的分析师报告会提及某种盈利倍数,而只有不到 13% 会提供任何形式的现金流折现模型。2 尽管如此,大多数投资者对市盈率倍数究竟意味着公司未来怎样的财务表现,或者一家公司的市盈率倍数可能如何随时间变化,并没有清晰的认识。

Introduction Price-earnings (P/E) multiples are by far the most popular valuation metric on Wall Street. A recent academic study found that 99.1 percent of analyst reports mention some sort of earnings multiple, and less than 13 percent provide any variation of a discounted cash flow model. 2 Still, most investors don’t have a clear sense of what a price-earnings multiple implies about a company’s future financial performance, or how a company’s price-earnings multiple will likely change over time.

相对倍数法的大量使用往往加剧了这一问题。投资者常常用苹果与橘子式的比较——将经济本质截然不同的企业拿来对比——来为自己的估值结论辩护。

The widespread use of relative multiples often compounds the problem. Investors frequently justify their valuation conclusions with apples-to-oranges comparisons of businesses with very different economics.

倍数无处不在,但总体而言,人们仍对其理解不深。

Multiples are ubiquitous but remain, on balance, poorly understood.

在这篇短文中,我们搭建了一座分析桥梁,连接市盈率(以及任何类型的倍数)与严谨的经济推理。接着,我们讨论相对倍数的作用,最后简要探讨估值中价格隐含预期的重要性。

In this short piece, we offer an analytical bridge between earnings multiples (and multiples of any kind) and sound economic reasoning. We then discuss the role of relative multiples and finish with a brief discussion of the importance of price-implied expectations in valuation.

投资行业有史以来最伟大的思想家之一马蒂·莱博维茨(Marty Leibowitz),在过去 20 年间通过一系列论文和专著探讨了这些课题(其中大部分工作是与斯坦利·科格尔曼合作的)。这些文章已被汇编成莱博维茨的新书《特许权价值:现代证券分析方法》(纽约:约翰·威利父子出版社,2004 年),我们强烈推荐希望深入研究这一估值主题的读者阅读。

One of the investment industry’s all-time great thinkers, Marty Leibowitz, covered many of these topics in a series of papers and monographs over the past 20 years (much of this work was in collaboration with Stanley Kogelman). These articles have been compiled for Leibowitz’s new book, Franchise Value: A Modern Approach to Security Analysis (New York: John Wiley & Sons, 2004), which we recommend highly for readers who want to delve into this valuation topic in more detail.

M&M把它融化在你的脑海里

M&MMelt it into Your Head

理解市盈率倍数的一个合理且直观的起点,是默顿·H·米勒(Merton H. Miller)和弗兰科·莫迪利亚尼(Franco Modigliani)在 1961 年发表的经典论文《股息政策、增长与股票估值》。在该文演示各种估值方法在理论上具有等价性的章节中,他们指出,投资者可以将一家公司的价值拆分为两个部分:

One sound and intuitive place to start to understand price-earnings multiples is Merton H. Miller and Franco Modigliani’s seminal 1961 paper, “Dividend Policy, Growth, and the Valuation of Shares”. In the section that demonstrates the theoretical equivalence of various valuation approaches, they show that an investor can express the value of a company in two parts: 3

价值 = 稳态价值 + 未来价值创造

Value = steady state value + future value creation

我们可以进一步定义等式右侧的每一项:

We can further define each of the terms in the right-hand side of the equation:

稳态价值 = 税后净营业利润(标准化)+ 现金及非经营性资产 / 资本成本

Steady state value = Net operating profit after tax (normalized) + cash and non operating assets Cost of capital And:

未来价值 = 投资 ×(资本回报率 – 资本成本)× 竞争优势期 ÷ 资本成本 ×(1 + 资本成本)

Future value = Investment * (Return on capital – cost of capital) * Competitive advantage period Cost of capital * (1 + cost of capital)

根据米勒和莫迪利亚尼(M&M)的研究,这一公式“具备若干揭示性特征,理应在估值讨论中得到更广泛的应用”。这些特征是什么?又如何为我们的估值讨论提供参考?以下是若干实际应用:

According to Miller and Modigliani (M&M), this formula “has a number of revealing features and deserves to be more widely used in discussions of valuation.” What are these features, and how can they inform our valuation discussion? Here are some of the applications:

该公式允许你将市盈率倍数拆解为商品成分和经济特许权成分。

• The formula allows you to disaggregate a price-earnings multiple into a commodity component and a franchise component.

• 投入资本回报率在估值中的核心意义顿时一目了然。

• Return on invested capital’s central significance in valuation becomes immediately clear.

该公式揭示了增长的放大效应——无论好坏。

• The formula reveals the magnifying impact of growth—for better or worse.

• 这一公式说明了在使用相对估值指标时应当遵循的恰当预防措施。

• The equation illustrates the proper precautions in using relative valuation metrics.

• 这个公式为评估一只股票所包含的市场预期,提供了一条非常便捷的指南。

• The formula offers a very handy guide for assessing the expectations in a stock.

我们来更仔细地看一下这些特点。

Let’s take a look at these features in some more detail.

拆解市盈率(上篇):稳态价值

Disrobing the Price-earnings Multiple Part I: The Steady State Value

稳态价值等于一家企业在不创造额外价值、仅维持其正常化盈利情况下的企业价值。4 请注意,稳态概念不涉及企业增长,它仅假设增量投资所赚取的收益等于资本成本。企业可以——也确实能够——在不创造股东价值的情况下实现每股收益的增长。该术语让我们能够计算稳态市盈率:5

The steady state value equals a business’s worth if it doesn’t create additional value and maintains its normalized earnings. 4 Note that the steady state says nothing about corporate growth, it only assumes the incremental investments will earn the cost of capital. Companies can and do grow earnings per share without creating shareholder value. This term allows us to calculate a steady-state price-earnings multiple: 5

稳态市盈率 = 1

Steady state price-earnings multiple = 1 .

资本成本

Cost of capital

如果我们假设资本成本为 8%——其中无风险利率 4%,股权风险溢价 4%——那么稳态市盈率倍数为 12.5 倍。市场认为,任何市盈率倍数高于 12.5 的公司,都有望在未来创造价值。如果一家公司的市盈率倍数等于或低于 12.5,市场要么假定它无法创造价值,要么预期未来的价值创造不足以抵消当前基础业务的下滑。

If we assume an 8 percent cost of capital—a 4 percent risk-free rate plus a 4 percent equity risk premium—the steady state price-earnings multiple is 12.5 times. The market expects any company with a P/E multiple above 12.5 to create future value. If a company has a P/E multiple at or below 12.5, the market either assumes no value creation or anticipates that future value creation will not offset a decline in the current base business.

我们也可以将稳态市盈率视为一种大宗商品估值倍数,是所有公司在其生命周期终点达到的水平。生命周期理论表明,赚取高于资本成本的回报的公司会吸引竞争,最终迫使行业回报降至资本成本水平。随着时间的推移,经济力量会将估值倍数压低至大宗商品或稳态水平。 6

We can also think of the steady state P/E as a commodity multiple, the level all companies reach at the end of their life cycle. Life cycle theory suggests that companies earning a return above the cost of capital will attract competition, eventually driving industry returns to the cost of capital. Over time, economic forces push multiples down to a commodity, or steady state, level. 6

图 1 显示了一家公司的合理市盈率如何随时间变化。在这个理论例子中,该公司第一年的投入资本回报率为 56%,盈利增长率为 25%。我们随后让回报率(从 56% 降至假设的 8% 资本成本)和增长率(从 25% 降至 5%)在 25 年内逐步衰减。值得注意的是,对于高增长、高回报的企业,合理市盈率接近 70 倍。

Exhibit 1 shows how the warranted P/E for a company changes over time. In this theoretical example, the company’s year 1 return on invested capital is 56% and the earnings growth rate is 25%. We then fade both the returns (from 56% to an 8% assumed cost of capital) and growth (from 25% to 5%) over 25 years. Note the warranted P/E is close to 70 for high growth, high return businesses.

当然,我们不能假设所有企业都能维持其常态化盈利。例如,我们知道美国吸烟的人越来越少,消费者也将继续从传统摄影转向数字摄影。我们可以使用戈登增长模型的一个变体,针对一个衰退的业务调整稳态模型:负增长率会降低分子价值,并提高我们对该现金流进行资本化的比率:7

Of course, we can’t assume all businesses will maintain their normalized earnings. For instance, we know fewer people in the U.S. are smoking and consumers will continue to migrate from traditional to digital photography. We can adjust the steady-state model for a declining business using a variation of the Gordon growth model. A negative growth rate lowers the value of the numerator and increases the rate at which we capitalize the cash flow: 7

修正后的稳态价值 = 税后净营业利润 (1 + 增长率)

Modified steady state value = Net operating profit after tax (1 + growth)

资本成本——增长

Cost of capital - growth

最后一个明显的要点是:那些接近商品类估值的公司,拥有稳定的基础业务和合理的未来价值创造前景,是良好的买入候选对象。

The last, obvious point here is that companies trading near a commodity multiple with a stable base business and reasonable prospects for future value creation are good candidates for purchase.

解读市盈率之二:价值增长型机会

Disrobing the Price-earnings Multiple Part II: Value Growth Opportunities

撰写本文时,标普 500 指数的市盈率约为 17.0 倍(基于 2005 年的一致预期)。如果这个公式成立,那么市场价值的 25% 或更多来自未来的价值创造。思考未来价值创造时,关键问题是什么?

At the time of this writing, the S&P 500’s P/E is about 17.0 based on consensus 2005 estimates. If the formula applies, 25 percent or more of the market’s value comes from future value creation. What are the key issues in thinking about future value creation?

分析了该等式中的第二项——莱博维茨称之为“经济特许权价值”——会发现三个关键驱动因素:

An examination of the equation’s second term, which Leibowitz calls the “franchise value”, reveals three key drivers:

资本回报率与资本成本之间的利差

• The spread between the return on capital and the cost of capital

投资规模

• The magnitude of investment

• 一家公司能够以正利差配置资本的时间有多长

• How long a company can deploy capital at positive spreads

当投资者和企业管理者思考估值时,通常首先想到的是增长。但第一个驱动因素恰恰说明,这种侧重完全错误。如果一家公司在新投入资本上赚取的回报恰好等于资本成本,那么公式中的第二项就归零,合理的估值就是普通市盈率。如果一家公司赚取了超额回报,第二项就是正值,这家公司就会为股东创造价值。最后,如果一家公司的回报低于资本成本,第二项就会减损价值,这家公司的交易价格就会低于普通市盈率。

When investors and corporate managers think about valuation, they often start with growth. But the first of these drivers shows why this emphasis is totally misplaced. If a company earns exactly the cost of capital on incremental investment, the second term of the equation collapses to zero and the appropriate valuation is the commodity P/E. If a company earns excess returns, the second term is positive and the company will create shareholder value. Finally, if a company earns below the cost of capital, the second term detracts from value, and the company will trade below the commodity P/E.

增长在估值中的作用完全取决于一家企业的经济回报。关键的是,公司可以在不产生超过资本成本的回报的情况下实现每股收益增长。8 正确的估值首先考虑回报利差,其次才是投资规模,也就是增长。(关于当前趋势的讨论,请参见附录 B。)

The role of growth in valuation completely depends on a firm’s economic returns. Importantly, companies can grow earnings per share without generating returns in excess of the cost of capital. 8 Proper valuation considers the return spread first, and the magnitude of the investment, or growth, second. (See Appendix B for a discussion of current trends.)

米勒与莫迪利亚尼在他们的论文中清晰地阐明这一观点:

Miller and Modigliani make this point clearly in their paper:

简而言之,“成长”的本质不是扩张,而是存在将大量资金投入并获取高于“正常”回报率的机会。

The essence of “growth,” in short, is not expansion, but the existence of opportunities to invest significant quantities of funds at higher than “normal” rates of return.

表格 2 说明这一点。表格的每一列代表不同的投入资本回报率水平,每一行代表不同的增长率。表格主体部分显示的是,基于回报与增长率之间的关系得出的市盈率(P/E)。

Exhibit 2 illustrates this point. The columns of the table are different return on invested capital levels, and the rows are varying growth rates. The body of the table contains the P/E’s that fall out of the return and growth relationships.

这张表格展示了三项基本原则。第一,一家盈利水平等于资本成本的公司,无论其增长如何,都会以普通商品的市盈率倍数交易。第二,盈利水平超出资本成本的公司,市盈率倍数会更高,而增长会大幅放大高回报的优势。最后,盈利水平低于资本成本的公司,市盈率倍数会较低。

The table shows three fundamental principles. First, a company earning its cost of capital will trade at a commodity P/E multiple, irrespective of its growth. Second, companies earning excess returns trade at premium P/Es, and growth strongly amplifies the benefits of high returns. Finally, companies earning below the cost of capital trade at low multiples.

投入资本回报率(按我们这里的定义)也代表一家企业在排除外部融资后的最大可持续增长率。9 通常情况下,高回报的投资机会本身稀缺,而非资本稀缺。可持续增长这一概念说明了,为什么在给定增长率之下,资本效率高的企业理应比资本效率低的企业获得更高的估值倍数。

Return on invested capital (as we define it here) also represents the maximum sustainable growth rate for a business excluding external financing. 9 Typically, high-return investment opportunities are scarce, not capital. The idea of sustainable growth shows why a capital-efficient business deserves a higher valuation multiple than a lower-capital efficiency business at a given growth rate.

虽然图 2 在理论上完全成立,在实际中也得到了验证。在图 3 中,我们选取了超过 2600 家美国公司,按照投资资本回报率(CFROI®)将其分为四组(列为四分位),再按预期盈利增长率进行交叉分组(行为四分位)。交叉点对应的数字,就是落在此区间内公司的市盈率中位数。例如,投资资本回报率最高但每股收益增长率最低的一组(右上角),市盈率中位数为 18.6 倍;而同一回报率组中增长率最高的公司(右下角),市盈率中位数为 22.3 倍。正如理论所示:对于高回报企业,增长率越高,价值越大;对于低回报企业,增长率反倒会减损价值。此外,在给定增长率的情况下,回报率越高,市盈率倍数也越高——右边三列代表盈利高于资本成本的企业。

While clearly sound in theory, Exhibit 2 also applies in reality. In Exhibit 3, we took over 2,600 U.S. companies and ranked them on CFROI® by quartile (columns). We then cross-ranked the CFROI quartiles by expected earnings growth rates (rows). Each resulting multiple is the median P/E of the companies that fall into that cell. For example, the companies in the highest CFROI quartile but lowest EPS growth quartile (upper right hand corner) have a median P/E of 18.6, while the highest growth companies in the same CFROI quartile (bottom right hand corner) have a P/E of 22.3. As theory suggests, higher growth adds value for high return businesses and detracts value for low return businesses. Further, multiples rise for a given growth rate as returns rise: the three columns on the right represent businesses earnings above the cost of capital. 10

教科书定义的投资回报率,是用损益表推导出的盈利分子(通常是税后净营业利润)除以资产负债表上的分母。投资就是当下支出现金,期望未来获得财务回报。历史上,公司进行的大部分投资,比如资本设备和存货,都会体现在资产负债表上。但随着我们越来越转向服务和知识经济,公司进行的许多投资,比如研发或培训,却体现在损益表上。要准确评估未来回报,投资者必须考虑所有投资,不管它们出现在财务报表的哪个位置。

The textbook definition of return on invested capital divides an income-statement-derived earnings numerator (typically net operating profit after tax) by a balance-sheet-based denominator. An investment is a current outlay today with the expectation of a future financial return. Historically, most of the investments companies made, like capital equipment and inventory, went on the balance sheet. However, as we shift more towards a service and knowledge economy, many of the investments companies make, like R&D or training, show up on the income statement. To assess future returns accurately, investors must consider all investments, irrespective of where they show up in the financial statements.

经济特许权价值的最后一个驱动因素,是超额收益投资机会的可持续性。正如我们之前所指出的,经济力量会随着时间推移,将投入资本回报率拉低至资本成本水平。这种回报率均值回归的现象,在实证研究中已有充分记载。¹¹

The final driver of franchise value is the sustainability of excess-return investment opportunities. As we noted earlier, economic forces drive the return on invested capital down to the cost of capital over time. This return reversion is well documented empirically. 11

投资者的一个核心任务是评估一家回报率高于资本成本的公司,能在多长时期内持续找到高回报的投资机会。股票价格往往反映了未来十到二十年的价值创造现金流。竞争战略分析在这项工作中尤其有用。

A central task for an investor is to assess how long a company earning above its cost of capital can continue to find productive investment opportunities. Stock prices often reflect ten to twenty years of value-creating cash flows. Competitive strategy analysis is particularly useful in this effort.

相对与可比倍数估值

Relative and Comparable Multiple Valuation

《巴伦周刊》的一名专栏作家最近提到,一位华尔街分析师仅仅说出“我们认为亚马逊是一家零售商”,就赢得了他的“衷心钦佩”。这句看似无害的话为何如此令人愉悦?因为,“我一直耐心等待华尔街停止对包括亚马逊在内的互联网时代宠儿给予天价溢价和特殊待遇的那一天。”

A Barron’s columnist recently suggested that a Wall Street analyst had won his “devoted admiration” with the simple proclamation, “We think Amazon.com is a retailer.” Why was this seemingly innocuous statement so pleasing? Because, “I have been patiently waiting for the day when Wall Street ends this nonsense of giving blue-sky premiums and special treatment to Internet-era darlings, including, but not limited to, Amazon.” 12

这种思维的潜台词是:既然亚马逊卖东西,投资者就该像给其他卖东西的公司估值那样给它估值。这种简单化的思维虽普遍存在,却完全错误。

The implication of this thinking is that since Amazon sells stuff, investors should value it like other companies that sell stuff. This simplistic thinking, while pervasive, is flat wrong.

正如图表 2 所示,企业估值不应取决于它做什么,而应看它的经济特质如何。除非是极少数例外,同一行业内公司之间的估值差异,反映的是预期的投入资本回报率与增长上的真实差距。一个同业群体里那些便宜的公司,往往自有其便宜的道理。

As Exhibit 2 demonstrates, company valuation should not be based on what the company does, but rather what its economics look like. With rare exception, valuation disparities between companies within the same industry reflect legitimate differences in expected return on invested capital and growth. Cheap companies within an industry peer group often deserve to be cheap.

在考虑可比倍数估值时,投资者必须超越商业属性(它们卖东西),聚焦于商业境况(它们赚取什么回报,承诺什么增长)。投资者必须先仔细描述一家公司的经济轮廓,才能明智地开始估值过程。

When considering comparable-multiple valuation, investors must look beyond the business attributes (they sell stuff) and focus on the business circumstances (what returns they earn and growth they promise). Investors must carefully describe the economic profile of a company before they can intelligently start the valuation process.

同样的思路也适用于思考股票相对于其历史估值倍数的交易位置。生命周期理论告诉我们,经济死神——即大宗商品的市盈率——终将降临到所有公司头上。

The same thinking applies to considering where stocks trade relative to their historical multiples. Life cycle theory tells us that the economic grim reaper—the commodity P/E—will eventually greet all companies.

均值回归意味着,商品市盈率对上市公司施加着一种引力。话虽如此,有些公司还是找到了结构性提升资本回报率的方法——通常是通过更好的资产负债表管理。¹³ 当一家公司的基本面经济特征发生变化时,历史市盈率对投资者毫无帮助。

Reversion to the mean implies that the commodity P/E exerts a gravitational pull on companies. That said, some companies figure out ways to structurally improve their returns on capital—often through better balance sheet management.13 Historical P/Es do not help investors when a company’s underlying economics change.

市场评论人士常常拿当下的市场市盈率与历史市盈率作对比,试图判断市场是否有吸引力。但要让市场平均值在不同时期具有可比性,统计总体的特征必须保持一致,或者说必须是平稳的。如果总体的特征随时间变化,数据就出现了非平稳性,那么基于历史比较的一切判断就不成立了(或者说根本就不该这么比)。

Pundits often compare today’s market P/E to past P/Es to divine whether or not the market is attractive. But for market averages to be comparable over time, the statistical properties of the population must be the same, or stationary. If the population’s properties change over time, the data are nonstationary and all bets based on comparisons are off (or should be).

针对市场市盈率的理论与实证分析表明,其并不具备平稳性。对过去 125 年的研究显示,年初的市盈率水平与随后 12 个月和 24 个月的回报之间,不存在统计上显著的相关关系。 14 市场市盈率非平稳性的三个主要驱动因素是:税收与通胀的作用、市场成分的变化,以及股权风险溢价的变化。 15

Theoretical and empirical analysis of P/E ratios for the market suggests nonstationarity. Research of the past 125 years shows no statistically significant relationship between a P/E ratio at the beginning of the year and the subsequent 12- and 24-month returns. 14 The three main drivers of P/E nonstationarity for the market are the role of taxes and inflation; changes in the composition of the market; and shifts in the equity risk premium. 15

期望值方法

The Expectations Approach

关于这一讨论,有一点很重要:一家公司的股价反映的是对未来财务表现的一系列预期。低市盈率通常反映的是低预期(且合理的预期),高市盈率则往往意味着过高的预期。投资者必须预见到预期的修正。

One important point about this discussion: a company’s stock price reflects a set of expectations about future financial performance. Low multiples generally reflect low (and justified) expectations and high multiples often indicate lofty expectations. An investor must anticipate expectation revisions.

预期形成过程分三步。第一步,搞清当前市场预期处在什么位置。

There are three steps to an expectations process. The first is to understand where expectations are today.

用一个高跳运动员可能取得成功的比喻来说,这一步确定了横杆当前的高度。

Using a metaphor of a high jumper’s likely success, this step determines the bar’s current height.

如果一家公司的市盈率高于大宗商品级别,那么这一评估就需要理解市场对其未来投入资本回报率、增长和可持续性的预期。使用贴现现金流模型和一致预期对股价进行逆向工程,是一个不错的起点。

If a company trades at a P/E above the commodity level, this assessment requires understanding the market’s expectations for future return on invested capital, growth, and sustainability. Reverse engineering the stock price using a discounted cash flow model and consensus estimates is a good start.

第二步是判断公司能“跳多高”,或者说它是否有可能超出已内含在价格中的预期。这需要财务与战略分析。

The second step is to determine “how high” the company can jump, or whether or not it is likely to exceed embedded expectations. This requires financial and strategic analysis.

最后一步是做出买入、卖出或持有的决策。通过设定一系列可能的价值结果及其概率,投资者可以计算出预期价值。以低于预期价值的价格交易的股票具有吸引力,但价格相对于预期价值的折价幅度,以及价值与价格差距最终弥合所需的时间,才最终决定超额收益的大小。

The final step is to make a buy, sell, or hold decision. Using a range of possible value outcomes and probabilities, an investor can calculate an expected value. Stocks trading at a discount to expected value are attractive, but the amount of the price discount to expected value and how long it takes for the value-to-price disparity to close ultimately determine excess returns.

价值投资与价值创造

Value Investing and Value Creation

把价值计算公式和预期投资法放在一起看,就能清楚为什么价值投资和成长投资的区别毫无意义。孤立地看增长,结果是无法确定的;投资者首先需要理解投入资本回报率。预期投资法表明,关键不在于今天隐含业绩的绝对水平,而在于预期会往哪个方向移动。

When taken together, the value equation and the expectations approach make it clear why distinctions between value and growth investing are vacuous. Growth considered in isolation is indeterminate; an investor needs first to understand returns on invested capital. Expectations investing shows that what matters is not the absolute level of today’s implied performance but rather where expectations will move.

经典价值投资者试图在价格与价值之间套利。他们的投资组合中往往充斥着那些确实便宜、且资本回报率等于或低于资本成本的企业。我们称这类投资者为“价值交易者”。

Classic value investors seek to arbitrage the difference between price and value. Often, they find their portfolios filled with justifiably cheap business that earn returns on capital near or below the cost of capital. We call these investors value traders.

理想情况下,价值投资者能找到这样一种企业:它的价格低于价值,并且这种价值会随时间推移而增长。

Ideally, value investors can find businesses with prices below value where the value will increase over time.

这种价值增长源于管理层成功地将资本配置到具备吸引力的回报上,同时抵御了向大宗商品式市盈率(P/E multiple)迁移的趋势。在这种情况下,投资者的价值创造以两种方式复利增长——随着价格与价值之间的差距缩小,以及随着价值本身的增长。

This value increase comes as management successfully deploys capital at attractive returns and fends off the migration to the commodity P/E multiple. In this case, value creation for the investor compounds in two ways— as the price to value gap narrows and as value grows.

Summary

Summary

常常被当作估值的东西,不过是简单套用历史倍数或相对倍数,而没有充分思考倍数究竟意味着什么。像米勒和莫迪利亚尼(Miller & Modigliani)40 多年前所做的那样,把估值拆解开,就能深刻理解到底是什么在驱动企业价值,进而理解估值本身。

Often what passes as valuation is the simple application of historical or relative multiples without full consideration of what a multiple means. Breaking down a valuation, as Miller and Modigliani did over 40 years ago, provides critical insights into what drives corporate value and hence valuations.

下面是我们最常看到的三个错误:

Here are three of the errors we see most often:

• 专注于增长而非回报。无论是公司还是投资者,通常都把增长视为一种绝对的好事。事实上,相当一部分公司高管的薪酬仍然取决于盈利增长。价值等式清楚地表明,增长只是一个放大器——它既可能对你有利,也可能对你不利。

• Focus on growth instead of returns. Both companies and investors generally consider growth an absolute good. Indeed, a substantial part of corporate executive compensation still hinges on earnings growth. The value equation shows clearly that growth is only an amplifier—and can work for you or against you.

• 根据公司属性(行业)而非其境况(经济模式)进行对比。历史上充斥着被颠覆性技术击败的公司。在众多此类案例中,颠覆性企业学会了在更低价格点上盈利——这往往得益于资产负债表利用效率的提升。将公司与行业同行进行比较,通常无法适当考虑回报与增长因素。

• Comparisons of companies based on their attributes (industry) instead of their circumstances (economic model). History is filled with companies that lost out to disruptive technologies. In many of those cases, the disruptive business learned to make money at a lower price point—often as the result of more efficient balance sheet utilization. Comparing companies to industry peers frequently doesn’t properly take into consideration returns and growth.

• 历史倍数法的使用。历史倍数仅在经济环境(无论是宏观还是微观)未发生变化时才适用。当一家公司失去其经济特许权时,其估值倍数会逐渐滑向大宗商品水平。在某些情况下,公司确实能找到方法提高回报率或延长超额回报周期,这两者都会导致其估值倍数高于历史数据所显示的水平。

• Use of historical multiples. Historical multiples only apply when the economic circumstances (both macro and micro) are unchanged. As a company loses its economic franchise, its multiple will drift to the commodity level. In some instances, companies do figure out ways to improve returns or extend their period of excess returns, both leading to higher multiples than history would indicate.

附录 A 这篇简短的附录主要阐述两个要点。第一,估值不会因为利率上升而改变,除非实际(经通胀调整的)折现率和/或实际增长率发生变化。大量证据表明,从整体而言,这些比率在长期具有极强的粘性。但投资者在评估具体公司时,仍需运用判断力。

Appendix A This short appendix makes two main points. First, valuation does not change in the face of rising rates unless the real (inflation-adjusted) discount rate and/or the real growth rate change. Substantial evidence suggests that these rates are very sticky over time in the aggregate. But investors must exercise judgment for an individual company.

第二,投资者在调整盈利增长率以反映通胀影响方面往往做得非常糟糕。通常情况下,投资者会拿近期的通胀率来做简单外推。莫迪利亚尼和科恩在 25 年前就曾有力地论证过这一点,而坎贝尔和沃提纳霍在近期的一篇论文中再次强调了该观点。16

Second, investors tend to be very poor at adjusting their earnings growth rates to reflect inflation. Generally, investors take recent inflation rates and extrapolate them. Modigliani and Cohn forcefully argued this point 25 years ago, and Campbell and Vuolteenaho reiterate the point in a current paper. 16

估值与费率调整

Valuation and rate changes

一个合乎逻辑的出发点是,无论你按实际值还是名义值对金融资产建模,最终得出的价值是一样的。

A logical starting point is to show that you get the same value if you model a financial asset on a real or nominal basis.

假设一家公司满足以下条件:17

Assume a firm and the following conditions: 17

可分配收益 = 100 美元 未来 3 年增长(实际) = 5% 3 年后增长(实际) = 3% 十年期国债收益率 = 4.75% 股权风险溢价 = 4% 贝塔系数 = 1.0 预期通胀率 = 3%

Distributable earnings = $100 Growth next 3 years (real) = 5% Growth beyond 3 years (real) = 3% Ten-year note = 4.75% Equity risk premium = 4% Beta = 1.0 Expected inflation = 3%

增长率是多少?

What are the growth rates?

实际 名义 前 3 年 5% (1.05)*(1.03) – 1 = 8.2% 3 年 + 3% (1.03)*(1.03) – 1 = 6.1%

Real Nominal First 3 years 5% (1.05)*(1.03) – 1 = 8.2% 3 years + 3% (1.03)*(1.03) – 1 = 6.1%

折扣率是多少?

What are the discount rates?

Real Nominal (1.0875/1.03) – 1 = 5.58% 4.75% + 1*(4.0%) = 8.75%

Real Nominal (1.0875/1.03) – 1 = 5.58% 4.75% + 1*(4.0%) = 8.75%

现金流是多少?

What are the cash flows?

年份实际现金流名义现金流
1105.0108.2
2110.3117.0
3115.8126.5
Year   Real Cash flow   Nominal Cash flow
1   105.0   108.2
2   110.3   117.0
3   115.8   126.5

终值是多少?

What are the terminal values?

Real Nominal 115.8*(1.03)/(0.558 – 0.03) = $4,617 126.5*(1.061)/(.0875 - .0601) = $5,045

Real Nominal 115.8*(1.03)/(0.558 – 0.03) = $4,617 126.5*(1.061)/(.0875 - .0601) = $5,045

当前价值是多少?

What are the present values?

Real Nominal

Real Nominal

105/1.0558 +   108.2/1.0875 +
110.3/(1.0558)2 +   117.0/(1+1.0875) 2 +
(115.8 + 4,617)/(1.0558)3   (126.5 + 5,045)/(1+1.0875)3
= $4,219   = $4,219
105/1.0558 +   108.2/1.0875 +
110.3/(1.0558)2 +   117.0/(1+1.0875) 2 +
(115.8 + 4,617)/(1.0558)3   (126.5 + 5,045)/(1+1.0875)3
= $4,219   = $4,219

核心要点是,在做模型时,保持现金流与折现率之间的一致性至关重要。

The main message is the importance of consistency in matching cash flows with discount rates when you model.

只要你认为实际增长率没有改变(即公司能够按照通胀率对其产品或服务定价),那么因通胀导致的名义折现率变动就不会改变价值。

Provided you feel real growth rates haven’t changed (i.e., the company can price its goods or services at the rate of inflation) a change in nominal discount rates due to inflation will not change value.

总体而言,利率上升与盈利增长率上升是一致的。

Broadly speaking, rising rates are consistent with rising earnings growth rates.

通胀幻觉

The Inflation Illusion

1979 年,莫迪利亚尼和科恩声称,股市投资者会受到“通胀幻觉”的影响。具体来说,他们认为股市投资者未能理解通胀对名义增长率的影响——相反,即便在通胀率不断变化的环境下,他们仍会机械地外推历史名义增长率。

In 1979, Modigliani and Cohn claimed stock market investors are subject to “inflation illusion.” Specifically, they argued stock market investors fail to understand the effect of inflation on nominal growth rates. Rather, they extrapolate historical nominal growth rates even in times of changing inflation.

认识到这一倾向后,投资者必须非常小心,以确保现金流和折现率保持一致。

Recognizing this tendency, investors must remain very careful to make sure cash flows and discount rates are consistent.

附录 B 投资水平和投入资本回报率是未来价值的三个驱动因素中的两个。如今的情况在这两方面都颇为耐人寻味。

Appendix B Level of investment and return on invested capital form two of the three drivers of future value. What’s going on today is interesting on both counts.

首先,让我们来看投资这一面。目前企业的投资支出占现金流和折旧的比例远低于历史水平。(见图表 4。)有三个因素有助于解释为何企业领袖们当前在花钱上十分谨慎。

First, let’s look at the investment side. Corporate investment spending today is well below historical levels as a percentage of cash flow and depreciation. (See Exhibit 4.) Three factors help explain why corporate chieftains currently have tight purse strings.

首先,1990 年代末出现了一段过度投资期。其次,政府对企业施加了监管负担,促使企业转向内部。最后,由于经济、监管和政治上的不确定性,市场一直缺乏信心。

First, there was a period of overinvestment in the late 1990s. Second, the government has placed regulatory burden on companies, prompting companies to turn inward. Finally, there has been a lack of confidence due to economic, regulatory, and political uncertainty.

因此,公司资产负债表的健康状况达到了有史以来的最佳水平。不过,有迹象表明,高管们正更加积极地配置资本,包括并购活动的增加。

As a result, corporate balance sheets are the strongest they have ever been. There is evidence, though, that executives are more actively deploying capital, including an uptick in M&A activity.

接下来我们考察回报端的情况。经历了 1990 年代末的回报繁荣和 2000 年代初的衰退之后,企业回报如今再次逼近历史最高水平。(见图表 5。)这种高回报很可能反映了近年来审慎——或者说谨慎——的资本配置。美国企业界的盈利远高于其资本成本。

Next, consider the return side. Following a return boom in the late 1990s and a bust in the early 2000s, corporate returns are now approaching all-time highs again. (See Exhibit 5.) These high returns likely reflect the judicious— or perhaps timid—capital deployment in recent years. Corporate America is earning well above its cost of capital.

接下来会发生什么?企业正在将注意力转向资本配置。可能的结局包括:并购活动升温、投资支出进一步复苏,以及通过股息和回购向股东返还现金的力度加大。

What’s next? Companies are now turning their attention to capital deployment. Possible outcomes include a boost in M&A activity, a further recovery in investment spending, and a more concerted effort to return cash to shareholders via dividends and share repurchases.
