回归第一性原理 [email protected] 假设你必须提出一个公平的出价来收购附近的一家干洗店,而卖家只允许你根据五个问题的答案来了解它的财务状况。你会问哪五个问题?
A Return to First Principles [email protected] Say you had to come up with a fair offer to buy your local dry cleaner and the seller limited the extent of your financial information to the answers to five questions. Which questions would you ask?
可能性在于,你不会去问这个季度的业绩进展如何,也不会问去年的盈利情况,而是会关注长期来看现金流入与流出之间的前景。
Chances are you wouldn’t ask how the quarter is progressing or about last year’s earnings, but you would focus on the prospects for cash coming in versus cash going out over time.
个体经营者深知,自家生意的价值完全取决于它所产生的现金流。没有可供支配的现金,就没有价值。现金能端上餐桌、能还清房贷,而盈利却不能。
Sole proprietors understand intimately that the value of their business hinges on the cash flow the business generates. No distributable cash, no value. Cash puts food on the table and pays the mortgage; earnings do not.
股权投资者就是企业买家。大多数股东虽然只拥有一家公司的一小部分,但他们终究是所有者。股东价值及其变化的来源,与独资经营者并无二致:一切都关乎现金。
Equity investors are business buyers. While most shareholders own only a small fraction of a company, they are owners nonetheless. The source of shareholder value, and value changes, is no different than the sole proprietor’s: it’s all about the cash.
大多数投资者并不这么思考。部分原因是,市场交易让投资者可以轻松地用今天的现金换取对未来现金流的索取权,反过来也一样,这让他们忘了自己是在评估、买入和卖出企业。然而,投资者——而非投机者——永远不应忘记自己的目标:以低于价值的价格买入一串现金流。
Most investors don’t think this way. In part, this is because market exchanges readily allow investors to trade cash today for claims on future cash flows, and vice versa, encouraging them to forget they are evaluating, buying, and selling businesses. Yet investors, as opposed to speculators, should never lose sight of their objective: buying a stream of cash flows for less than what it is worth.
既然现金流入与流出是企业价值的命脉,你可能会以为投资者会热衷于衡量和评估现金流。事实上,债券和商业地产市场的估值完全围绕现金展开。然而在实际操作中,极少有股票投资者会认真琢磨现金流。利润和倍数这类价值替代指标,主导了华尔街的估值工作。
Given that cash inflows and outflows are the lifeblood of corporate value, you might expect investors to be intent on measuring and valuing cash flows. Indeed, valuation in the bond and commercial real estate markets is all about cash. In practice, however, very few equity investors dwell on cash. Proxies for value, like earnings and multiples, dominate Wall Street valuation work.
因为市场大体上是有效的,投资者可以使用价值代理指标而不必理解这些指标实际代表什么,这样做不会出大问题。结果是自满,以及一种虚假的理解感。因此,大多数投资者不做基本面估值工作;即使做了,也常常做得不对。
Because markets are mostly efficient, investors can get away with using value proxies without awareness of what the proxies actually represent. The result is complacency and a false sense of understanding. As a consequence most investors don’t do fundamental valuation work; when they do, they often do the work incorrectly.
第一性原理告诉我们,给一家企业估值的正确方法是估算未来现金流的现值。虽然大多数华尔街专业人士在学校里都学过贴现现金流模型,但在实际工作中,他们构建并依赖的那些模型存在严重缺陷。毫不意外,这些贴现现金流模型的置信度非常低。这种微弱的信心并非对分析方法的否定,而是对分析方式的否定。
First principles tell us the right way to value a business is to estimate the present value of the future cash flows. While most Wall Street professionals learned about discounted cash flow (DCF) models in school, in practice the models they build and rely on are deeply flawed. Not surprisingly, the confidence level in these DCF models is very low. This faint confidence is not an indictment of analytical approach but rather of analytical methods.
DCF 模型应当在经济逻辑上合理且透明。经济逻辑合理,意味着公司的回报和增长模式与其市场定位一致,并且与大量支持均值回归的实证记录相符。透明,则意味着你清楚自己所选方法和假设的经济含义。大多数 DCF 模型都未能达到经济合理性和透明度的标准。
DCF models should be economically sound and transparent. Economically sound means the company’s return and growth patterns are consistent with the company’s positioning and the ample empirical record supporting reversion to the mean. Transparent means you understand the economic implications of the method and assumptions you choose. Most DCF models fail to meet the standards of economic soundness and transparency.
The List
The List
以下是我们整理的 DCF 模型中最常见的错误清单。建议你对照这份清单检查自己的模型,或者你看到的模型。如果其中有一项或多项错误出现,那么该模型对商业判断的参考价值就会非常有限。
Here’s our list of the most frequent errors we see in DCF models. We recommend you check your models, or the models you see, versus this list. If one or more of the errors appear, the model will do little to inform your business judgment.
1. 预测期限过短。对 DCF 模型最常见的批评之一是,任何超过几年的预测都不可靠。因此,据称投资者最好使用确定性更强的短期盈利预测。
1. Forecast horizon that is too short. One of the most common criticisms of DCF models is that any forecast beyond a couple of years is suspect. Investors, therefore, are alleged to be better off using more certain, near-term earnings forecasts.
这种推论毫无道理,至少有两个原因。第一,理解一家企业的吸引力,关键在于弄清楚当前价格所代表的那套财务预期是什么。从历史来看,整个市场的市盈率倍数通常在 15 到 19 倍之间。简单的数学计算就能说明,今天的股价反映的是对未来很多年里能创造价值的盈利和现金流的预期。
Such reasoning makes no sense, for at least two reasons. First, a key element in understanding a business’s attractiveness involves knowing the set of financial expectations the price represents. The market as a whole has historically traded at a price-to-earnings multiple in the mid-to-high teens. Simple math shows today’s stock prices reflect expectations for value-creating earnings and cash flows many years in the future.
为了把这一点说得更具体,假设你是一位餐饮业高管,负责寻找新的门店选址。在评估一个潜在选址的吸引力时,你会因为“两年之后的数字全是猜测”就只看它两年的盈利吗?当然不会。
To make the point more concrete, imagine you are a restaurant industry executive in charge of finding new store locations. When assessing the attractiveness of a prospective site, would you consider only two years of earnings because “any beyond that is guessing”? Of course not.
你判断的依据会是地段、类似场地的历史业绩,以及其他与价值相关的因素。明智的资本配置者会着眼长远。
You’d base your judgment on the location, past results for similar sites, and other value-relevant factors. Intelligent capital allocators take a long-term view.
短期预测周期与反映长期现金流的资产价格之间的错配,带来了第二个问题:投资者必须通过在模型的其他地方补充价值,来补偿过短的周期。最常被用来兜售价值的,就是持续性价值,也就是终极价值。结果往往是得到一个完全不符合经济逻辑的持续性价值。这种价值错配,让模型的两个部分——预测期和持续性价值估算——都近乎毫无用处。
The mismatch between a short forecast horizon and asset prices that reflect long-term cash flows leads to the second problem: investors have to compensate for the undersized horizon by adding value elsewhere in the model. The prime candidate for the value dump is the continuing, or terminal, value. The result is often a completely non-economic continuing value. This value misallocation leaves both parts of the model—the forecast period and continuing value estimate—next to useless.
有些投资者因为 DCF 模型假设太多,直接弃之不用。但他们却欣然接受另一种方法——把所有同样的假设,毫无透明度地一股脑塞进一个单一数字:市盈率。市盈率不是估值,它只是估值过程的速记符号。和大多数速记形式一样,市盈率也有盲点和偏差,但很少有投资者花时间、用心去真正理解它们。
Some investors swear off the DCF model because of its myriad assumptions. Yet they readily embrace an approach that packs all of those same assumptions, without any transparency, into a single number: the multiple. 3 Multiples are not valuation; they represent shorthand for the valuation process. Like most forms of shorthand, multiples come with blind spots and biases that few investors take the time and care to understand.
约翰·梅纳德·凯恩斯有句名言:“我宁愿模糊地正确,也不愿精确地错误。”他的这句话在这里也适用。我们建议明确预测期至少不少于五年,并指出许多公司需要超过十年的价值创造现金流才能支撑其股价。理想情况下,明确预测期应至少捕捉到公司三分之一的价值,同时对预测的财务表现有清晰的假设。
John Maynard Keynes famously said, “I’d rather be vaguely right than precisely wrong.” His message applies here. We recommend explicit forecast periods of no less than five years, and note many companies require over ten years of value-creating cash flows to justify their stock prices. Ideally, the explicit forecast period should capture at least one-third of corporate value with clear assumptions about projected financial performance.
虽然随着时间推移,可能的结果范围确实会扩大,但我们拥有更好的分析工具来处理一个模糊的未来,而不是给一个更确定的近期每股收益数字附上一个不确定的倍数。下面我们来讨论不确定性这个问题。
While the range of possible outcomes certainly widens with time, we have better analytical tools to deal with an ambiguous future than to place an uncertain multiple on a more certain near-term earnings per share figure. We address the uncertainty issue below.
2. 不经济的持续价值。DCF 模型中的持续价值部分,捕捉的是企业在明确预测期之后的价值,理论上可以延伸至永续。
2. Uneconomic continuing value. The continuing value component of a DCF model captures the firm’s value for the time beyond the explicit forecast period, which can theoretically extend into perpetuity.
在构建 DCF 模型框架时,投资者必须留意微观经济学中最有力的法则之一:竞争力量会确保长期来看,投资回报将趋近于资本成本。大量实证研究记录了这种均值回归现象,生命周期理论也阐述了这一过程。² 因此,构建 DCF 模型的一个合理方式是:用明确预测期来捕捉新投资带来的超额回报(即价值创造),而持续价值部分则反映公司耗尽其增量价值创造机会之后的价值。见图表 1。
While developing a DCF model’s structure, investors must mind one of microeconomics’s most powerful lessons: competitive forces assure that return on investment will approximate the cost of capital over time. Numerous empirical studies document this reversion to the mean, and life cycle theories express the process. 2 Accordingly, one reasonable way to structure a DCF model uses the explicit forecast period to capture the excess returns on new investment (value creation) with the continuing value component reflecting value after the company exhausts its incremental value-creation opportunities.

在实际操作中,我们很少见到这种结构。在我们收集的一组卖方模型样本里,观察到的预测期都太短,通常只有五年或更短。预测期过短的关键后果是,建模者为了让模型与市场价格保持一致,不得不把价值负担全部压在持续价值估算上。结果,模型无法清晰反映公司的价值创造模式或时间节奏。现实中,大多数分析师对自己采用的持续价值假设所隐含的意义了解甚少。
We rarely see this structure in practice. Based on a sample of sell-side models we gathered, we observed forecast periods that are too short, generally five years or less. The crucial consequence of a too-short forecast period is the modeler has to heap the value burden on the continuing value estimate in order to have any consonance with the market price. As a consequence, the model fails to reflect a clear sense of the company’s pattern or timing of value creation. In reality, most analysts understand little about the implications of their continuing value assumptions.
例如,建模者通常用期末息税折旧摊销前利润(EBITDA)乘以一个倍数来估算持续价值。这个倍数鲜有牢固的经济基础,大多数分析师也根本不清楚该倍数对财务表现意味着什么。
For instance, modelers commonly apply a multiple to ending-period earnings before interest, taxes, depreciation, and amortization (EBITDA) to estimate continuing value. The assigned multiple rarely has a solid economic foundation, and most analysts have no idea what the multiple implies about financial performance.
举个例子,在特定假设下,13.0 倍的 EBITDA 倍数意味着 6% 的利润增长率以及永续的 150% 增量资本回报率。4 郑重声明,人类历史上没有任何一家公司实现过这样的财务表现。持续价值所占的高比例几乎总意味着预测期设定不当。
As an example, given certain assumptions a 13.0 times EBITDA multiple implies 6 percent earnings growth and a 150 percent return on incremental capital in perpetuity. 4 For the record, no company in the history of mankind has achieved such financial performance. A high percentage of value accorded to the continuing value almost always reflects an improper forecast period.
相反,将模型划分为价值创造期和价值中性期,不仅在经济学上合理,还能让模型更加清晰。我们可以捕捉到
In contrast, segregating the model into a period of value creation and value neutrality not only makes sound economic sense, but allows for greater model clarity. We can capture the
继续使用永续年金假设来估算持续价值,将最后一年的税后净营业利润按资本成本进行资本化。这一价值,即使折现到现在,也通常占公司价值的 60% 到 70%。
continuing value with a perpetuity assumption, capitalizing the last year’s net operating profit after tax by the cost of capital. This value, even discounted to the present, often represents 60-70 percent of corporate value.
此外,永续假设恰好捕捉了均值回归现象。该方法假设增量投资回报等于资本成本。随着时间的推移,旧投资的折旧与新投资的增加自然确保公司替换其投入资本基础。当公司对所有旧的、创造价值的投资完成折旧后,剩余投入资本所赚取的正好是资本成本。公司的资产寿命决定了这一回归过程的时间长度。资产寿命短的公司会迅速替换其投入资本基础,并较快回归至资本成本回报率。资产寿命长的公司则恰恰相反。
Moreover, a perpetuity assumption neatly captures the reversion-to-the-mean phenomenon. The approach assumes incremental returns on investment equal the cost of capital. Over time, naturally, depreciation of old investments and addition of new investments assure a company replaces its invested capital base. After the company depreciates all its old, value-creating investments, the remaining invested capital earns exactly the cost of capital. A company’s asset life determines the length of this reversion process. A short-asset-life company will rapidly replace its invested capital base and revert to cost-of-capital returns quickly. The opposite is true for a long-asset-life company.
许多分析师错误地认为,永续经营法不反映明确预测期之后的增长。这种假设是错误的。永续假设并不排除增长。但由于增长与价值创造之间并无必然联系,企业可以在不创造任何股东价值的情况下继续增长。永续法的核心假设与增量价值创造有关,而非增量增长。附录 A 论证了这一点。
Many analysts incorrectly assume the perpetuity approach does not reflect growth beyond the explicit forecast period. This assumption is wrong. The perpetuity assumption does not rule out growth. But since growth has no necessary link to value creation, companies can continue to grow without creating any shareholder value. The essential assumption of the perpetuity approach relates to incremental value creation, not incremental growth. Appendix A demonstrates this point.
大多数 DCF 模型在经济合理性和透明度这两项测试上都不及格,原因是结构糟糕:明确的预测期太短,而终值估计承载的价值又过大。
Most DCF models fail the economically sound and transparent test because of poor structure: the explicit forecast periods are too short and the continuing value estimates carry too much value.
投资者应当清楚地理解自己所选用的任何持续价值方法背后所依据的经济假设或隐含意义。
An investor should have a clear handle on the economic assumptions or implications behind whatever continuing value approach they choose.
3\. 资本成本。你很少会看到哪个优秀的权益投资者,把“比其他人更会判断资本成本”说成是自己重要优势的来源。但你确实会看到很多 DCF 模型,因为一个荒谬的资本成本估算而丧失价值。
3. Cost of capital. You’ll rarely see a great equity investor point to an ability to judge the cost of capital better than others as the source of meaningful edge. But you do see many DCF models debilitated by a nonsensical cost of capital estimate.
资本成本,是对投资者要求持有某项资产所应获得回报率的一个估算,或者说,就是投资者的机会成本。正因如此,资本成本是用于将未来现金流折现到现值的恰当利率。
The cost of capital is an estimate of the rate of return an investor demands to hold an asset or, said differently, an investor’s opportunity cost. As such, the cost of capital is the proper rate for discounting future cash flows to a present value.
大多数公司主要通过债务和股权来为其运营融资。债务成本,尤其是对大型公司而言,通常是透明的,因为公司有合同义务按时支付票息并偿还本金。在无风险证券的基础上给予一定的收益率溢价是合理的,溢价的大小反映了公司的信用状况。规模庞大且流动性通常较强的公司债券市场,使得固定收益证券之间的比较相对直接。
Most companies finance their operations largely through debt and equity. The cost of debt, especially for large companies, is generally transparent because companies have contractual obligations to make coupon payments and return principal on a timely basis. Some yield premium over risk-free securities is appropriate, with the size of the premium reflecting the company’s creditworthiness. The large and generally liquid corporate bond market makes comparisons between fixed-income securities relatively straightforward.
估算股权成本更具挑战性。与债务的显性成本不同,股权成本是隐性的。由于股权的求偿权层级较低,其成本高于债务成本。但并没有简单的办法可以估算股权成本。
Estimating the cost of equity is more challenging. Unlike debt’s explicit cost, the cost of equity is implicit. The cost of equity is higher than the cost of debt because equity’s claim is junior. But no simple method exists to estimate the cost of equity.
到目前为止,估算权益成本最常用的方法就是资本资产定价模型(CAPM)。CAPM 认为,一家公司的权益成本等于无风险利率加上权益风险溢价与贝塔值的乘积。政府发行的债券通常能很好地作为无风险利率的替代指标。而权益风险溢价和贝塔值的估算则要棘手得多。
By far the most common approach to estimating the cost of equity is the capital asset pricing model (CAPM). The CAPM says a company’s cost of equity equals the risk-free rate plus the product of the equity risk premium and beta. Government-issued notes generally provide a good proxy for the risk-free rate. Estimates for the equity risk premium and beta prove more challenging.
先从贝塔系数说起,这个指标试图反映一只股票的价格波动相对于大盘的敏感程度。贝塔值为 1.0,意味着该股票的走势通常与市场同步。贝塔低于 1.0,表明股票波动小于市场;而贝塔高于 1.0,则意味着波动大于市场。在其他条件相同的情况下,金融理论将较高的贝塔值与较高的风险和回报挂钩。
Let’s start with beta, which attempts to reflect the sensitivity of a stock’s price movement relative to the broader market. A beta of 1.0 means the stock tends to move in line with the market. A beta below 1.0 suggests a stock moves less than the market, while a beta above 1.0 implies moves greater than the market. All things equal, finance theory associates a higher beta with higher risk and reward.
贝塔在理论上很完美,但在实践和实证中却站不住脚。实际应用的问题在于,CAPM 中究竟该选用哪个贝塔值。理想情况下,我们需要前瞻性的贝塔,但这根本无法可靠估算。贝塔的实证失败则反映在:多项研究表明,贝塔对回报的解释力很差。
Beta is wonderful theoretically but fails practically and empirically. The practical failure surrounds what beta to actually use in the CAPM. Ideally, we want forward-looking betas, which we cannot reliably estimate. Beta’s empirical failure reflects studies showing beta does a poor job explaining returns. 5
彭博终端上的数据清楚揭示了盲目使用 CAPM 的问题。2006 年 3 月中旬,通用汽车的贝塔值为 1.3,而雅虎的贝塔值超过 1.6。从事商业活动的人很难认同,在适当的预测时间跨度内,雅虎的风险会显著高于通用汽车。事实上,隐含期权波动率显示,通用汽车的风险高于雅虎。虽然评估企业的相对风险显然很有价值,但投资者必须对各种服务机构提供的数据做出自己的判断。
A visit to the Bloomberg terminal shows the problem with blithely using the CAPM. In mid-March 2006, General Motors had a beta of 1.3 while Yahoo! had a beta in excess of 1.6. It would be hard for a businessperson to argue that Yahoo is likely to be significantly more risky than General Motors over an appropriate forecast time horizon. Indeed, the implied option volatilities suggest more risk at GM than YHOO. While gauging the relative risks of businesses is clearly valuable, investors have to impose judgment on the figures the various services produce.
CAPM 的第二个重要输入变量是股权风险溢价——投资者预期在无风险利率之上获得的额外回报,作为承担更高风险的补偿。
The second important input into the CAPM is the equity risk premium, the return above and beyond the risk-free rate an investor expects to earn as compensation for assuming greater risk.
与贝塔值一样,股权风险溢价在理想情况下也应是前瞻性估计。大多数分析师依赖历史股权风险溢价数据,而这些数据——视所取的时间框架而定——未必能合理反映未来的回报前景。
Like beta, the equity risk premium is ideally a forward-looking estimate. Most analysts rely on past equity risk premiums, which, depending on the time frame, may not give a reasonable sense of the return outlook.
资本成本的大多数问题,都源于贝塔系数和股权风险溢价输入数据的陈旧。例如,使用几何平均法计算的股权风险溢价,1982 年至 2005 年为 1.9 个百分点,1962 年至 2005 年为 3.7 个百分点,1926 年至 2005 年为 6.2 个百分点。同一时间段内,算术平均法计算的股权风险溢价更高。
Most of the problems with the cost of capital come from stale inputs for beta and the equity risk premium. For example, the geometric average equity risk premium was 1.9 percentage points from 1982-2005, 3.7 percentage points from 1962-2005, and 6.2 percentage points from 1926- 2005. 6 The arithmetic average equity risk premiums during the same time frames were higher.
估值领域的一个争论点是,几何平均值与算术平均值哪个更合适。我们倾向于在长期模型中使用几何回报,在短期回报预测中使用算术平均值。7
One area of debate in valuation is whether the geometric or arithmetic average is more appropriate. We favor geometric returns for long term models and arithmetic averages for short-term return forecasts. 7
此外,研究表明股权风险溢价可能并非固定不变,这意味着使用历史平均值可能极具误导性。具体而言,影响股权风险溢价的变量——如过往股票回报、股价波动率以及商业状况——显然会发生变化,因此事前股权风险溢价也很可能随之改变。
In addition, research suggests the equity risk premium is probably nonstationary, which means using past averages may be very misleading. Specifically, variables shaping the equity risk premium—like past stock returns, stock price volatility, and business conditions—clearly change, making it likely the ex-ante equity risk premium changes as well. 8
不论你在当前无风险利率 4.7%(2006 年 3 月中旬)的基础上加上 200 个基点还是 600 个基点*,都会对模型的输出结果产生显著影响。图 2 展示了近期卖方分析师报告中采用的部分股票风险溢价样本。我们的最佳建议是,确立一个在商业和经济意义上都合理的资本成本。部分学者认为股票风险溢价在 3 到 4 个百分点之间,这在我们看来是合理的。9 这一范围的中位数意味着长期市场回报率大约在 8% 左右。
Whether you add 200 or 600 basis points* to the current risk-free rate of 4.7 percent (mid-March 2006) will make a significant difference in the model’s output. Exhibit 2 shows a sample of equity risk premiums assumed in recent sell-side analyst reports. Our best advice is to settle on a cost of capital that makes business and economic sense. Some academics suggest the equity risk premium is in the 3 to 4 percentage point range, which strikes us as reasonable. 9 The midpoint of this range implies a market return of roughly 8 percent over time.

最后,虽然围绕资本成本做一些敏感性分析有时是有用的,但我们认为,投资者把精力放在关键经营价值驱动因素(销售增长、利润率、资本密集度)的各种情景假设上,会更划算得多。资产错配有时确实会表现为高贴现率,就像我们在 2002 年底高收益债券市场上看到的那样。但即便在那时,你也可以说,优秀的投资者历来都是靠比市场更懂价值驱动因素而获得优势的。
Finally, while some sensitivity analysis around the cost of capital can be useful, we would argue investors are much better off considering alternative scenarios for the key operating value drivers (sales growth, margins, capital intensity). Sometimes asset mispricings do show up as high discount rates, as we saw in the high-yield bond market in late 2002. But even there, you could argue great investors have historically generated an edge by understanding the value drivers better than the market.
4. 假设投资与盈利增长错配。公司要想实现长期增长,不可避免地必须对业务进行投资——通过营运资本、资本支出、收购、研发等方式。投资回报率(ROI)决定了一家公司将投资转化为盈利增长的效率。由于 ROI 将投资与增长联系在一起,而且 ROI 长期内往往趋向于资本成本,投资者必须审慎对待投资与增长之间的关系。
4. Mismatch between assumed investment and earnings growth. Companies invariably must invest in the business—via working capital, capital spending, acquisitions, R&D, etc.—in order to grow over an extended period. Return on investment (ROI) determines how efficiently a company translates its investments into earnings growth. Since ROI links investment and growth, and ROIs tend toward the cost of capital over time, investors must treat the relationship between investment and growth carefully.
DCF 模型通常低估了为实现假设增长率所需的投资。这一错误往往源于两个原因。第一,分析师在考察那些过去频繁进行收购的公司时,会将收购推动的增长率外推,却只反映现有业务的资本支出和营运资金需求。你可以通过仔细考虑当前业务可能实现的增长——这会低于收购驱动的增长率——来减轻这一错误。
DCF models commonly underestimate the investment necessary to achieve an assumed growth rate. This mistake often comes from two sources. First, analysts looking at companies that have been highly acquisitive in the past extrapolate an acquisition-enhanced growth rate while only reflecting capital spending and working capital needs for the current business. You can mitigate this error by carefully considering the growth likely to come from today’s business—which will be less than an acquisition-fueled rate.
低估投资的第二个原因,在于人们往往未能通过投资回报率(ROI)将增长与投资明确联系起来。分析师们常常预测增长(销售额和利润率),
The second reason for underestimating investment stems from a simple failure to explicitly link growth and investments via ROI. Analysts frequently project growth (sales and margins)
不依赖于投资。检验这一错误的一个简单方法是在财务模型中加入一条 ROI(投资回报率)线。如果你看到 ROI 大幅上升或下降,但背后并没有深思熟虑的战略基础,那么这个模型很可能不可靠。我们见到过的绝大多数模型都没有努力去反映增长与投资之间的关联。
independent of investments. A simple way to check for this error is to add a ROI line in the model. If you see ROIs rising or dropping sharply without a thoughtful strategic underpinning, the model is likely unreliable. The vast majority of the models we see make no effort to reflect a link between growth and investment.
5. 对其他负债的错误反映。在广泛使用的企业自由现金流估值法中,分析师依据未来现金流的现值来确定企业价值。然后,分析师加上现金及其他非经营性资产,再减去债务及其他负债,从而得出股东价值。
5. Improper reflection of other liabilities. In the widely-used free cash flow to enterprise approach, an analyst determines the corporate value based on the present value of future cash flows. The analyst then adds cash and any other nonoperating assets and subtracts debt and any other liabilities to arrive at shareholder value.
大多数负债——包括债务和许多养老金计划在内——相对容易确定,也能直接反映到模型里。但另一些负债,比如员工股票期权,就难处理得多。不出意外,大多数分析师在以一种经济上合理的方式捕捉这些负债时,做得非常糟糕。
Most liabilities, including debt and many pension programs, are relatively straightforward to determine and reflect in the model. Some other liabilities, like employee stock options, are trickier to capture. Not surprisingly, most analysts do a very poor job capturing these liabilities in an economically sound way.
我们要指出的是,其他负债通常只对少数公司重要。例如,其他退休后员工福利计划主要集中在制造业(如汽车行业),而员工股票期权则最常出现在知识和服务行业(如科技和金融服务)。投资者必须在其对公司价值影响较大的行业中,恰当地识别其他负债。
We would note that other liabilities tend to be important for only a handful of companies. For example, other postretirement employee benefit plans tend to concentrate in manufacturing industries (e.g., autos) while employee stock options occur most frequently in knowledge and service industries (e.g., technology and financial services). Investors must properly recognize other liabilities in the sectors where they have a large impact on corporate value.
员工股票期权很好地说明了这一常见缺陷。大多数 DCF 模型仅通过稀释后股份来反映过去的期权授予。当然,由于稀释后股份只反映价内期权,这种方法根本无法准确捕捉负债的规模。10 尽管会计准则现在要求公司将期权确认为费用,但我们发现很少有 DCF 模型明确将未来期权授予视为费用处理。分析师模型常常显示流通股数增加(稀释),有时又会将期权行权收入纳入模型而不反映任何稀释效应。
Employee stock options are a good illustration of this common shortcoming. Most DCF models simply reflect past option grants through fully diluted shares. Of course, since fully diluted shares only reflect in-the-money options, the solution does an awful job of capturing the magnitude of the liability. 10 While accounting standards now require companies to expense options, we have found few DCF models that explicitly treat future option grants as an expense. Often, analyst models show rising shares outstanding (dilution) and models sometimes include option proceeds without reflecting any dilution.
我们可以妥善处理员工股票期权(ESOs),将已授予的期权视为一项或有负债,使用已发行的基本股份数量,并将未来授予的期权记为一项费用。这种方法能够对过去授予的期权进行动态评估,并将未来授予视为一种经济费用。
We can deal with ESOs appropriately by treating already-granted options as a contingent liability, using basic shares outstanding, and reflecting future option grants as an expense. This approach allows for a dynamic appraisal of past option grants and considers future grants as an economic expense.
6. 相较非公开市场价值的折价。我们看到,作为 80 和 90 年代投资银行家思维留下的不幸后遗症,如今仍有人先用 DCF 模型算出一个价值,然后以“公开市场折扣”的名义再砍掉 20-25%。这种做法在电信行业最为普遍。
6. Discount to private market value. In what we’d characterize as an unfortunate hangover from the 1980s and 1990s investment-banker mentality, we still see DCF models that calculate a value, only to modify the amount by a “public market discount” of 20-25 percent. This practice seems most prevalent in the telecommunications industry.
这种做法通不过透明度检验。要理解这一点,我们必须倒置折价思维,问一问:为什么一个私人(战略或财务)买家会愿意支付高于公开市场价值的溢价?
This practice fails the transparency test. To see the point, we have to invert the discount mindset and ask why a private (strategic or financial) buyer would pay a premium to public market value.
也许私人买家认为股票被低估了(这种情况下溢价会抵消掉好处)。更可能的是,买家相信自己能从收购资产中产生比目标公司自身更高的现金流。
Perhaps the private buyer believes the stock is undervalued (in which case the premium wipes out the benefit). More likely, the buyer believes it can generate a higher stream of cash flows from the acquired assets than the target company can by itself.
协同效应,即两家公司合并带来的好处,往往能解释大部分甚至全部溢价。另一种情况是,收购方可能以不同的方式配置资本,或者运用财务杠杆来提升税后现金流。
Synergies, the benefits of putting two companies together, often justify most if not all of the premium. Alternatively, a buyer may allocate capital differently or use financial leverage to enhance after-tax cash flows.
要说得通,反映公开市场折价的 DCF 模型必须已经包含协同效应或其他该公司单靠自身无法实现的提高现金流催化因素。
To be sensible, a DCF model reflecting a public market discount must already incorporate synergies or some other catalyst for higher cash flows the company cannot achieve on its own.
对可能的交易协同效应进行建模是可以的,但这项工作应与对独立业务的估值分开进行。按低于私人市场价值的折扣进行估值这一模型缺乏足够的透明度,因为它混淆了基础现金流与协同效应现金流。
Modeling possible deal synergies is fine, though the exercise should remain separate from valuing the standalone business. The discount-to-private-market-value model lacks sufficient transparency because it conflates the base and synergy cash flows.
7. 重复计算。模型不应将同一美元的价值(或负债)计算两次以上。在不知不觉中,DCF 模型常常会将同一价值来源重复计算在内。
7. Double counting. Models should not count a dollar of value (or liability) more than once. Unwittingly, DCF models often double count the same source of value.
以股票回购为例。那些产生强劲自由现金流的企业,通常有回购股票的历史,而且这一做法很可能延续下去。分析师们看到了回购倾向和强劲现金流这两点,有时会直接将回购纳入模型,假设企业用自由现金流持续减少流通股。这就造成了重复计算——模型既对现金流估值(一次),又用同一笔现金流来减少流通股(第二次)。这种重复计算错误还绕开了判断未来股价这一分析难题(要准确估算一家公司可能回购多少股票,唯一恰当的方式就是看股价)。
Take share repurchase, for instance. Companies generating strong free cash flow often have a record of buying back stock that is likely to continue. Analysts, recognizing both a proclivity toward buybacks and strong cash flow, sometimes build buybacks into their models by assuming the company uses free cash flow to shrink shares outstanding over time. This double counts because the model values the cash flow (once) and the model uses the same cash flow to reduce shares outstanding (twice). This error of double-counting leaves aside the analytical challenge of judging the future stock price (the only way to properly determine how much stock a company might buy).
另一个不那么常见的重复计算例子,是把利息收入计入现金流,同时又把现金余额加到公司价值里。另一种做法是,有些分析师从现金流中减去融资成本,再从公司价值中扣除债务,从而得出股东价值。
Another less frequent example of double counting involves the practice of including interest income in the cash flow calculation and adding the cash balance to corporate value. Alternatively, some analysts subtract financing costs from cash flow and then deduct debt from corporate value to come up with shareholder value.
8. 情景分析。对 DCF 模型最常见的批评可能是:假设条件的微小变动会导致估值结果大幅变化。在讨论前两种错误时,我们已经部分回应了这一担忧——延长预测期可以在一定程度上缓解这个问题。
8. Scenarios. Probably the most-often-cited criticism of a DCF model is that small changes in assumptions can lead to large changes in the value. We addressed part of that concern, which can be mitigated by lengthening the forecast horizon, in our discussion of the first two errors.
再进一步说,我们看到的大多数报告只提供一个 DCF 情景,分析师常常据此设定目标价。既然投资天生就是概率性的,那么单一情景——往往还建立在摇摇欲坠的假设之上——根本算不上彻底的分析。一个聪明的投资者必须考虑多种情景。
Going one step further, the large majority of reports we see offer one DCF scenario, and analysts often peg their target prices on that scenario. Given investing is inherently probabilistic, one scenario—often backed by shaky assumptions—does not constitute thorough analysis. An intelligent investor needs to consider multiple scenarios.
尽管许多 DCF 模型确实包含了敏感性分析(通常是一个由不同的资本成本、增长率或终值假设驱动的数值网格),但这些网格对任何试图理解企业前景的人来说,能提供的相关信息少得可怜。投资者应该关注的是价值驱动因素——销售额、利润率以及投资需求——这些都是产生不同预期的来源。
Though many DCF models do incorporate sensitivity analysis (typically a grid of values driven by alternative cost of capital, growth, or terminal valuation assumptions), these grids provide little relevant information for anyone trying to understand the prospects of the business. Investors should look to the value drivers—sales, margins, and investment needs—as sources of variant perception.
即使基于价值驱动因素的敏感性分析,通常也存在缺陷,因为它未能考虑价值驱动因素之间的交互作用。恰当的情景分析会考虑销售、成本和投资的变化如何导致价值驱动因素的不同结果。¹¹ 参见图表 3。
Even sensitivity analysis based on the value drivers is generally flawed because it fails to consider the interactivity between value drivers. Proper scenario analysis considers how changes in sales, costs, and investments lead to varying value driver outcomes. 11 See Exhibit 3.

情景分析同样应对了关于不确定未来的担忧。通过考虑“如果……那么……”
Scenario analysis also addresses concerns about an uncertain future. By considering “if, then”
坚持对情景进行分析,并要求预期价值有适当的折让——即安全边际——投资者就能安全而审慎地权衡各种结果。

Conclusion
Conclusion
理论与实践都告诉我们,一家公司的价值就是其未来现金流的现值。
Theory and practice tell us the value of a company is the present value of future cash flows.
投资者主要追求的是以低于其价值的价格买入一串现金流——或以高于其价值的价格卖出一串现金流。因此,投资者需要能够明智地对现金流进行建模,并识别出一种异见:即有充分理由相信市场对一家公司给出了错误的定价。
Investors primarily seek to buy a stream of cash flow for less than it’s worth—or sell a stream for more than it’s worth. Accordingly, an investor needs to be able to model cash flows intelligently and identify a variant perception: a well-founded belief the market has placed an incorrect value on a company.
商学院的学生们学透了 DCF 模型,课堂上也常演练怎么建模型。可一旦把模型往现实世界套,投资者必须确保模型在经济上站得住脚、且透明清晰。实际操作中,极少有模型能通过这两道检验。
Business school students learn all about DCF models, and they often practice building them in a classroom setting. But when applying the models to the real world, an investor must ensure the models are economically sound and transparent. In practice, very few models pass these tests.
我们已经找到导致失败的几个关键领域,并就如何弥补这些不足提出了一些想法。
We have tried to identify the key areas of failure, and offer some thoughts about how to address the shortcomings.
附录一:为什么增长不等同于价值
Appendix A: Why Growth Doesn’t Equate to Value
以下是计算持续价值(即超过明确预测期之后的价值)的标准方法:
Here’s the standard method for calculating continuing value, or value beyond the explicit forecast period:
价值 = 第 1 年税后营业净利润(NOPAT) / (资本成本 - 增长率) × (1 - 增长率 / 投入资本收益率)
Value = NOPATCAP+1 * (1- growth/ROIIC)
WACC – g
WACC – g
Where:
Where:
NOPATCAP+1 = 预测期后第一年的标准化 NOPAT;Growth = NOPAT 的增长率;ROIIC = 增量投资资本回报率;WACC = 加权平均资本成本。
NOPATCAP+1 = Normalized NOPAT in the first year after the forecast period Growth = Growth in NOPAT ROIIC = Return on incremental investment WACC = Weighted average cost of capital
NOPAT 是税后净营业利润的英文缩写。
NOPAT is an acronym for net operating profit after tax.
该方法与永续自由现金流(FCF)方法在基本假设相同的情况下完全一致。以下是永续自由现金流方法:
This method is identical to the free cash flow (FCF) in perpetuity approach when the underlying assumptions are the same. Here’s the FCF in perpetuity approach:
价值 = FCFCAP + 1 WACC – g
Value = FCFCAP + 1 WACC – g
我们用几个数字来演示一下这种等同关系。假设:
Let’s plug in some numbers to demonstrate the equivalence. Assume:
NOPATCAP+1 = 100 美元,增长 = 5%,ROIIC = 12%,WACC = 9%
NOPATCAP+1 = $100 Growth = 5% ROIIC = 12% WACC = 9%
标准公式:
The standard formula:
Value = 100 * (1- (5%/12%)) = 58.33 = 1,458.3 9% - 5% 4%
Value = 100 * (1- (5%/12%)) = 58.33 = 1,458.3 9% - 5% 4%
为了用自由现金流法计算价值,我们需要知道投资规模。注意,自由现金流等于税后净营业利润减去投资。
In order to calculate the value using the FCF method, we need to know the magnitude of investment. Note that FCF equals NOPAT – Investment.
已知起始的 NOPAT、增长率和 ROIIC,我们就能计算出投资额:
Since we know the starting NOPAT, growth, and ROIIC, we can calculate investment:
ROIIC * 1 号投资 = 'NOPAT2-1
ROIIC * investment1 = 'NOPAT2-1
5% 的 NOPAT 增长率告诉我们,NOPAT 从 100 增长到了 105。因此 NOPAT 的变化是 5。[第 2 年 NOPAT 105 减去第 1 年 NOPAT 100 = 5]。我们还知道 ROIIC 是 12%。所以:
A 5% NOPAT growth rate tells us that NOPAT is going from 100 to 105. So the change in NOPAT is 5. [Year 2 NOPAT of 105 minus Year 1 NOPAT of 100 = 5]. We also know ROIIC is 12%. So:
12% * investment = 5
12% * investment = 5
Investment = 5/12% = 41.67
Investment = 5/12% = 41.67
现在,我们知道自由现金流(FCF)= 58.33。[100 的税后营业利润减去 41.67 的投资等于 58.33]。
Now, we know that FCF = 58.33. [NOPAT of 100 minus Investment of 41.67 = 58.33].
因此,永续自由现金流模型得出:
So the FCF in perpetuity model gives:
Value = 58.33 = 58.33 = 1,458.3 9% – 5% 4%
Value = 58.33 = 58.33 = 1,458.3 9% – 5% 4%
所以,标准公式和永续自由现金流法,只要你的假设保持一致,得出的答案是完全一样的。
So the standard formula and the FCF in perpetuity approaches give the exact same answer provided your assumptions are consistent.
当增量投资回报率(ROIIC)等于加权平均资本成本(WACC)时,标准公式和永续自由现金流(FCF)都会坍缩为永续假设;也就是说,当增量回报等于资本成本,或者等价地,增量投资的净现值为零时。
Both the standard formula and the FCF in perpetuity collapse to the perpetuity assumption when ROIIC equals WACC; that is, when incremental returns equal the cost of capital or, equivalently, incremental investments have a zero net present value.
让我们保持所有假设不变,只改变投入资本回报率(ROIIC),将其设定为等于资本成本。
Let’s hold all of our assumptions constant except ROIIC, which we’ll set equal to the cost of capital:
NOPATCAP+1 = 100 美元 增长 = 5% ROIIC = 9% WACC = 9%
NOPATCAP+1 = $100 Growth = 5% ROIIC = 9% WACC = 9%
现在的标准公式是:
The standard formula now yields:
Value = 100 * (1- (5%/9%)) = 44.44 = 1,111.1 9% - 5% 4%
Value = 100 * (1- (5%/9%)) = 44.44 = 1,111.1 9% - 5% 4%
永续自由现金流模型同样如此。首先,我们需要重新计算投资额:
The same is true for the FCF in perpetuity model. First, we need to recalculate the investment:
| 项目 | 计算 |
|---|---|
| 9% × 投资额 = 5 | 投资额 = 5 / 9% = 55.56 |
| 因此, | 自由现金流 = 44.44 [100 – 55.56 = 44.44] |
| 价值 = | 44.44 / (9% – 5%) = 44.44 / 4% = 1,111.1 |
9% * investment = 5 Investment = 5/9% = 55.56 So, FCF = 44.44. [100 – 55.56 = 44.44]. and Value = 44.44 = 44.44 = 1,111.1 9% – 5% 4%
直接永续假设其实很简单:
The straight perpetuity assumption is simply:
价值 = NOPAT/CAP + 1/WACC
Value = NOPATCAP + 1 WACC
Or:
Or:
Value = 100 = 1,111.1 9%
Value = 100 = 1,111.1 9%
如果你假设 ROIIC 等于 WACC,那么所有持续价值方法都会坍缩为永续年金的价值。预测期之后的增长本身并不重要。
All continuing value methods collapse to the same value as a perpetuity if you assume ROIIC equals WACC. Growth beyond the forecast period does not matter in and of itself.

以下是一段近期卖方研究报告的引文:“折现现金流常被吹捧为首选方法,然而现值往往对终端价值假设最微小的调整都极其敏感。因此,我们总是回到那个简单却有效的办法——对未来期间收益使用倍数估值。”
3 Here’s a quotation from a recent sell-side research report, “Discounted cash flow is often touted as the preferred approach; however, present values are often terribly sensitive to the most minute tweak of one’s terminal value assumptions. So, we keep coming back to the simple but effective method of applying multiples to the earnings of future periods.”
我们假设折旧为 EBITA 的 20%,税率为 35%。然后选取 6% 的增长率,反推出投入资本回报率。
4 We assumed that depreciation equals 20 percent of EBITA and a 35 percent tax rate. We then selected the six percent growth rate and solved for the ROIC.
