Composite Equity Issuance (Cei) Can be a Proxy for Intangible Returns Anomalies

Even though factor investing is widely supported in academia and investment practice, forecasting and harvesting factor returns remains challenging for various reasons. One signal that has received more than a little attention of late is share buybacks.

In this paper, we discuss some of the flaws with using buybacks on their own as a forecasting metric and highlight that a more holistic view of shareholder activity both addresses these flaws and potentially helps explain the portion of stock returns not due to changes in fundamentals. In doing so, we take a novel approach to decompose this more holistic metric, known as Composite Equity Issuance (CEI), to isolate the elements of equity capital structure decisions.

A recent research was done by Northern Trust Asset Management to study efficacy of CEI as factor.  The research used equity return and equity fundamental data from 1969 to 2018 for the U.S. and 1998 to 2018 for World ex U.S. and Emerging Market.  The research shows this CEI metric has historically generated higher returns and Sharpe Ratios than buybacks around the globe. Indeed, we see this is empirically the case with CEI outperforming a net share issuance measure (includes both buybacks and share issuances) in the U.S., World ex U.S. and Emerging Markets*[1] annually by 1.4%, 2.2%, and 0.3%, respectively, with meaningful improvements in risk-adjusted measures as well.

The CEI anomaly was first documented by Kent Daniel and Sheridan Titman in their 2006 paper, Market Reaction to Tangible and Intangible Information [1]. In their paper, the authors break down stock returns into intangible and tangible components and conclude that the return associated to changes in accounting metrics – the tangible return – has no predictive power on future stock returns. In other words, everything that is known from an accounting perspective at a given time appears to be priced in. However, the intangible return, which reflects expectations of firms’ future earnings and growth potential, does account for pricing anomalies.

The difficulty, of course, is identifying metrics that can forecast intangible returns, which is where CEI comes into play. As a proxy for intangible information, the authors find that, when adding CEI to a multivariate regression that includes tangible and intangible return proxies, “the composite share issuance variable [that is, CEI] is significantly negatively related to future returns, providing further evidence that stock prices perform well (poorly) subsequent to the realization of unfavorable (favorable) intangible information”. Note that a high CEI implies a growth in the shareholder base and can be viewed as ‘unfavorable’. In other words, a change in composite share issuance has information about future stock returns. The implicit assumption behind using CEI to proxy intangible returns is that a firm’s management has better information than what is reflected in financial statements, thus their reaction to share price in the form of issuance or buybacks contains relevant information. Through an understanding of CEI and its underlying components, we can attain a greater understanding of the relationship between CEI and intangible returns.

Composite Equity Issuance Decomposition

At a high level, CEI “measures the amount of equity the firm issues (or retires) in exchange for cash or services. Thus, seasoned issues, employee stock option plans, and share-based acquisitions increase the issuance measure, while repurchases, dividends, and other actions that take cash out of the firm reduce the issuance measure.” To help simplify this description, we take the original CEI formula and decompose it into two elements: change in shares outstanding and dividend yield.

The original mathematical form for composite equity issuance can be found in Daniel and Titman 2006 paper and shown below:

From equation [2], it is obvious that composite equity issuance is comprised of two basic factors:

  1. Share Changes (including issuances and buybacks) and
  2. Dividend yield

In the next section, we focus on the individual components of Equation 2.

Share Changes and Dividend Yield: The Whole is Greater Than the Sum of The Parts

Share changes – including buybacks and issuances – and dividend yield are well-known measures that help understand management’s views on valuations and potential business opportunities:

  • Share changes are mostly due to share buyback programs and, to a lesser extent, secondary share issuances. Share buybacks can take several forms including open market, private transactions, and Dutch auctions but the most well-known and used ones are open market share buybacks. A traditional view for stock buybacks is that they are a positive signaling from management that their stock is undervalued and thus makes a good “investment”. Conversely, when companies issue stock, this can create an impression of the firm taking advantage of high stock valuations. Buybacks and issuances can also be used to change the capital structure of the firm.  Within the low-interest rate environment since the financial crisis, relatively cheap debt has made debt financing more attractive than equity financing.  As a result, buybacks have become a more dominant form of earnings distributions in the U.S [4] generating an intense debate over their merits.[2]
  • The dividend yield has been a hallmark for value investors for at least since Ben Graham wrote The Intelligent Investor and Security Analysis books over 70 years ago. A company that pays a consistent and stable dividend that is well covered by its internally generated cash flows can be considered healthy and profitable. Raising dividend payouts is widely seen as a signal that a company’s management is confident in the company’s ability to generate future cash flows while cutting dividends can be seen as a negative sign of the company’s future earning power as well as a potential signal to the marketplace that the company needs to reserve liquidity for other purposes, often-times related to solvency.

Though share changes and dividend yield have been useful forecasting variables independently, we find that combining them into a single metric provides a more potent effect because it considers the interaction of the variables. For example, a company may issue shares (viewed negatively) to maintain or increase its dividend (viewed positively). Taking these together allows the investor to view changes to the entire equity capital base.  Of course, companies buy back their stock for several reasons, some wholesome, others more ambiguous. These include tax related, corporate actions, signaling, pressure from activist hedge funds [6], and employee stock options. Although outside the scope of this paper, an investor’s best defense to these issues with buybacks is to take a more holistic view of a company’s fundamentals that includes profitability and cash flow measures – collectively what we refer to as Quality.[3]In the next section we look at the empirical analysis surrounding the efficacy of share changes, dividend yield, and the combined CEI metric.

In Exhibits 1 – 3, we show the returns of share changes, dividend yields, and the combined CEI measures across Russell 1000, MSCI World ex U.S., and MSCI Emerging Markets indexes.

In our research, for each region, we create equally weighted portfolios split across five quintiles where Quintile 1 – Q1 represents the lowest CEI and Share changes and the highest dividend yield while Quintile 5 – Q5 represents the opposite.

Exhibits 1 to 3 show annualised returns and information ratios for these portfolios.

Exhibit 1: Russell 1000

 In the U.S. market, the Q1 portfolio for CEI outperformed Share Change by 77 bps and Dividend Yield by 131 bps on an annualised basis, respectively, over the last 50 years.  The top two quintiles for CEI are visibly better performing than those for Share Change and Dividend Yield. In addition, the dispersion of returns and risk adjusted returns between the top and bottom quintiles is higher for CEI than for the other two measures, which further supports the CEI’s efficiency.

Exhibit 2: MSCI World ex U.S.

In the World ex U.S. market, the Q1 portfolio for CEI outperformed Share Change and Dividend Yield by 192 bps and 27 bps on an annual basis, respectively, over last 20 years.  Although the return dispersion between the top and bottom quintiles is somewhat smaller than in the U.S., we still see the same general pattern, supportive of CEI in developed international markets.

Exhibit 3: MSCI Emerging Market

Lastly, in the Emerging Markets, the Q1 portfolio for CEI outperformed Share Change and Dividend Yield by 368 bps and 58 bps on an annual basis, respectively over the last 20 years. While the return dispersion across the quintiles is somewhat more varied than in the Developed markets there is still a significant differential between the top and bottom quintiles especially on a risk adjusted basis.

Across the globe, we see the positive effects of using CEI to capture changes in equity capital structure rather than looking at Share Change and Dividend Yield individually. In this case, the whole signal is indeed greater than the sum of the parts.

CEI is a Useful Proxy to Intangible Returns

Understanding stock pricing anomalies is a critical step to being able to harvest them in one’s equity portfolio.

In the case of the stock market, it can be helpful to decompose a stock’s total return into a tangible piece related to changes in fundamentals, and an intangible piece that incorporates all other information. Although there are no direct metrics for the intangible return, one proposal would be to look at the Composite Equity Issuance (CEI) as a useful proxy to help forecast intangible returns. In this paper, we discussed and decomposed CEI into its component parts and demonstrated how it is an improved measure to its individual components, including Share Buybacks. Using metrics that take a holistic view of the interaction between firm’s management actions and shareholder activity like CEI may improve investors’ ability to understand and forecast stock return anomalies.
