Smart vs. Dumb Growth Stocks
To illustrate the intuition supporting the empirical evidence, we explore several examples of smart and dumb growth stocks. The stock of a company with a low return on capital and a management investing rapidly to increase its scale of operations is a dumb growth stock. In contrast, the stock of a company with a high return on capital with a management that demonstrates discipline and skill in capital allocation is a smart growth stock. Our examples look at three points in time: the height of the dot-com bubble (July 1999), the eve of the global financial crisis (July 2000), and more recently, July 2016.
Let’s begin with the dumb growth stocks.
We examine three dot-com stars—Compaq, Yahoo, and WorldCom—which, like many companies in the late 1990s, were aggressively investing for growth in the new internet-connected economy.
Compaq was the largest manufacturer of personal computers in the 1990s.5 To build scale, Compaq, despite (or because of) falling profits, invested heavily in a series of aggressive acquisitions.6 These acquisitions failed to produce the hoped-for economies of scale, while the rapid expansion caused quality control problems. We were not able, for example, to write this article on a Compaq machine, because the company was acquired at a fraction of its peak price by Hewlett-Packard in 2002.7
Yahoo, in the late 1990s, was expected by the stock market to attain a leading (if not the dominant) place in the exciting new field of web search. Despite little apparent profitability at the time, Yahoo invested aggressively to capture “eyeballs” and traffic. Although web search did become extremely valuable, Yahoo did not. Simply put, Google came along and did search much better.
WorldCom was the second-largest long-distance communication provider in 1999, a position achieved through aggressive acquisitions of technologies and networks. WorldCom financed its (loss-making) growth using rapid stock issuance, large amounts of debt, and some accounting fraud. When investors discovered that the industry had massively overinvested in fiber optic communication infrastructure, the game was up. WorldCom filed for Chapter 11 protection in 2002.
Financials, in the lead-up to the global financial crisis of 2008, are another example of dumb growth. Politicians, the media, and too many investors viewed securitization of mortgage debt as modern financial alchemy. Many of the banks that were among the most aggressive in stuffing their balance sheets with mortgage-backed securities have since failed or been acquired at fire-sale prices, leaving investors high and dry.
Now, let’s look at a few examples of smart growth stocks, in particular, Coca-Cola, Exxon, and Kellogg’s.
Over the three periods we examine, these companies have consistently ranked at the top of large companies sorted by high profitability and conservative investment. Each has cultivated its competitive advantage to dig a moat around its profitability. The managements of these companies have been careful stewards of their investors’ capital. All three slowly and steadily grew to global dominance in their industry.
Yes, of course, we cherry-picked these examples. Nonetheless, these vivid descriptions of dumb-versus-smart growth stocks illustrate empirical facts: companies with high investment, despite low profitability, fail to provide strong returns to shareholders, and in contrast, companies with high profitability, paired with low investment, deliver sustainably high returns.
More recently, Tesla, Facebook, and Netflix are examples of companies with an aggressive level of investment combined with a low return on capital. Are these companies poised to be the next Apple and Google, or will they go the way of Compaq, Lehman, and WorldCom? We have no specific information about the future prospects of these high-flying market darlings, but history teaches that, on average, companies with a low return on capital, paired with aggressive investment, have provided poor returns to investors.8
Conclusion
Growth managers strive to pick the next Google or Microsoft and to be rewarded with outsized profits as these new star companies rise to become tomorrow’s behemoths. The poor average performance of growth funds demonstrates that consistently identifying such stocks ex ante isn’t easy. Companies with rapidly expanding EPS too often trade at expensive valuations. For every Google, there are many also-rans.
We demonstrate a systematic method of growth investing that avoids the slower growth in EPS and negative excess returns of traditional growth strategies. By investing for sustainable growth, as indicated by profitable companies with disciplined investment, investors can diversify their value strategies, while achieving faster growth in EPS and positive excess returns. Our research points to a smart beta strategy that aims for sustainable growth.

3. According to Hsu, Myers, and Whitby (2016), growth managers as a group have generated an average annualized return of 8.4% over the period January 1991–June 2013, whereas the S&P 500 Index has generated a 9.0% average return over the same period.
4. Two main explanations are offered for why these new factors deliver superior performance. The first is a risk-based explanation that argues if companies continue to be highly profitable while engaging in relatively minimal investment, it must be because they face a high cost of capital; otherwise, why wouldn’t they invest? A high cost of capital implies that these companies are somewhat riskier, so investors must be compensated for the risk in the form of higher expected returns. The second explanation is behavioral, and argues that profitability is persistent, but investors do not fully realize this; therefore, the persistence of profitability is not fully reflected in current prices. The behavioral explanation for the investment factor is that investors tend to extrapolate high growth in assets into high growth in earnings and, thus, tend to overpay for the earnings growth.

6. The largest of these, Digital Equipment Corporation, was acquired at a then-record price of just over $9 billion.
7. Compaq was acquired by Hewlett-Packard (HP) in 2002. Gurrib (2015) shows that Compaq’s shareholders benefited more than HP shareholders from higher EPS from the merger. We find it unlikely, however, that this one-time increase in EPS from the merger adequately compensated Compaq shareholders who experienced negative returns in 1999 and 2000 as well as forgone earnings yield as a result of imprudent acquisitions. WorldCom filed for Chapter 11 bankruptcy in 2002; unambiguously, shareholders were worse off as a result. In either case, shareholders paid a multiple for future growth and returns that were not realized.
8. We are fans of Elon Musk and his vision for self-driving electrical cars, colonizing Mars, the Hyperloop, and so forth, but in July 2017, as we are completing this article, the capitalization of Tesla is almost 45% larger than the valuation of Ford, with much lower output and much lower profits. Are we certain that Tesla will grow to dominate the very competitive automobile market as the stock is currently priced? Or is everyone such a fan of Elon Musk that they are willing to pay top dollar for participating in his projects and underestimating the risk?

10. In the appendix, we provide results for the large-cap and small-cap portfolios, along with the details of our portfolio construction.
11. This may seem counterintuitive, however, considering the return decompositions of the large-cap and small-cap universes, which we provide in the appendix. We find that within the large-cap universe, the earnings growth contribution is as expected: positive for growth and negative (or at least negligible) for value. Within the small-cap universe these relationships are reversed, and the small-cap effect dominates the blended portfolios in the table “Decomposition of Log Real Returns of Large-Cap and Small-Cap Factor Portfolios in Excess of Benchmark.” One possible explanation for the negative contribution from earnings growth among small growth companies is that these small companies tend to have more uncertain and volatile earnings. If investors over-extrapolate future earnings growth of these small firms, their stock price will be bid up relative to their book value and realized earnings growth will subsequently create a negative drag on returns as earnings mean revert from an unsustainable level. For small-cap value companies, depressed earnings rebound from a smaller base over the holding period, so that earnings growth contributes positively to returns.
12. Using data from Hsu, Myers, and Whitby (2016), we regress the AUM-weighted average one-month mutual fund returns for growth managers in excess of the risk-free rate on a Fama–French three-factor model plus momentum. We find that the growth managers have a large negative (−0.26) and statistically significant (t-stat of −12.91) loading on the Fama–French value factor.
13. This regression is by no means meant to be conclusive; in particular, because it is based on just one cross-section of data and does not account for how these relationships may have changed over time. The regression is only meant to illustrate the incentive to grow assets that is faced by CEOs and that may create unintended consequences for investors.
