Screening for Value Using the Fundamental Rule of Thumb
by John Bajkowski
Investors deal with a number of trade-offs in their security selection and analysis. Seeking out stocks that offer high levels of current income entails giving up some growth potential. This basic trade-off is illustrated clearly by the Fundamental Rule of Thumb screen, which combines earnings yield, dividend yield, and the ratio of earnings retained to book value. All of these elements are well known and frequently used by value investors. When combined, a score is computed that can help indicate if a stock merits further analysis.
The rationale for a screen that combines earnings yield, earnings retention, and dividend yield is simple: Every value investor should seek growth and dividends at a bargain price. Of course, growth and dividends in one company are often contradictory, and therefore trade-offs are necessary. Exceptional growth can offset a low or non-existent dividend yield and can be worthy of further analysis if the stock price is relatively low. On the other hand, a high dividend yield and a low price relative to earnings can compensate for lower growth.
A screen that follows the Fundamental Rule of Thumb approach is built into Stock Investor Pro, AAIIs fundamental stock screening program and research database. The screening criteria used in the program are detailed at the end of the article.
The companies passing the screen, along with a simple hypothetical portfolio, have been reported and tracked on AAII.com for the last six and a half years (see Figure 1). The screen lagged the market in 1998 and 1999, a period in which the market favored growth strategies over value approaches. Its subsequent performance has been very strong on both an absolute and relative basis. The screen even managed to show a positive gain during 2002, a year in which most market segments experienced strong declines. Overall, the cumulative gain for the screen is 265.8% compared to a 14.9% gain for the S&P 500.
The primary components of the screen are earnings yield, earnings retained to book value, and dividend yield. Earnings yield is simply earnings per share divided by share price:
|Earnings Yield = EPS ÷ Price|
|EPS||=||Earnings per share for the most recent 12 months|
|Price||=||Market price per share of the common stock|
The earnings yield relates the generation of earnings to the stock price. A high earnings yield is desirable. Earnings per share and price are also the components of the price-earnings ratio (price per share divided by earnings per share); it is the reciprocal of the earnings yield.
|P/E Ratio||=||Price ÷ EPS|
|=||1 ÷ (EPS ÷ Price)|
In this form, it is apparent that a relatively high earnings yield is equivalent to a relatively low price-earnings ratio. Numerically, for example, if the earnings yield for a stock is 5%, its price-earnings ratio would be 20 (1 ÷ 0.05)in other words, the price is 20 times earnings per share. The lower the earnings yield, the higher the equivalent price-earnings ratio.
The market is forward-looking in its analysis. If it expects high future growth in earnings for a given stock with great certainty, it may be willing to accept a lower earnings yield (higher price-earnings ratio) today for that stock.
The characteristics of the stocks passing the Fundamental Rule of Thumb screen are presented in Table 1, while Table 2 lists the top 25 companies currently passing the criteria, as ranked by their rule of thumb score.
NRG Energy leads the pack with the highest earnings yield figure of 127.4%. This translates to a price-earnings ratio of 0.78 (1 ÷ 1.274)an unusually low number that probably points to a data anomaly. As it turns out, NRG emerged from bankruptcy late last year and adjusted its books to reflect the fair market value of its assets and liabilities. This fresh start accounting adjustment boosted net income for the period prior to reorganization to $2.8 billion, resulting in trailing-12 month figures that are not representative of current or future operations. Conseco and Bay View Capital have also had recent financial statement adjustments from reorganizations. NAVTEQ Corporation and Cohen & Steers are examples of freshly listed stocks that underwent reorganizations and financial statement adjustments prior to their initial public offerings.
Overall, the median price-earnings ratio of the Rule of Thumb stocks is over a quarter of the market level5.3 vs. 19.5.
Earnings and Value
The second component of the Fundamental Rule of Thumb is the ratio of earnings retained to book value. Earnings retained are simply annual earnings after the annual dividends have been paid to preferred and common shareholders. Earnings retained are reinvested by the firm and determine the growth in book value.
Book value consists of all of the assets of the firm, less all debt and other obligations. When divided by the number of outstanding common shares, the figure becomes book value per share. The book in book value is an accounting determination rather than a market valuation. Book value is often termed equity, shareholders equity or net worth.
|Ratio of Earn. Ret. to Book Val. =|
|(EPS DPS) ÷ BVPS|
|EPS||=||Earnings per share|
|DPS||=||Dividends per share|
|BVPS||=||Book value per share|
The ratio of earnings retained to book value measures change or growth in book value, but it is better thought of as an adjusted return on equity, or sustainable growth rate. The more commonly used return on equity figure is the ratio of earnings per share to book value. If no dividend is paid, return on equity equals earnings retained to book value. Carmike Cinemas passed the screen with a 50.1% ratio of earnings retained to book value. Carmike Cinemas earned $10.29 per share over the last four quarters, has an indicated annual dividend payout of $0.70 per share and a book value per share of $19.13. These figures lead to an extremely high 50.1% ratio [($10.29 $0.70) ÷ $19.13], but a number of one-time actions led to these values. Carmike Cinemas emerged from Chapter 11 reorganization in 2003 with a low book value from many years of significant losses. In late 2003, it recorded a deferred tax asset valuation credit of $75.3 million resulting in a one-time earnings gain over the last four quarters and an inflated ratio of earnings retained to book value as well as an inflated earnings yield.
The ratio of earnings less dividends to book value is the most intricate and difficult to interpret, primarily because of the book value figure and the many factors that can impact earnings.
The third fundamental value ratio is the dividend yield, which relates the annual cash dividend on the common stock to the current market price of the common stock.
|Dividend Yield = DPS ÷ Price|
|DPS||=||Indicated dividend per share|
|Price||=||Market price per share of the common stock|
While this screen seeks high dividend yields, it is important to remember the trade-off between the dividend yield and future growth rate. The more dividends that are paid, the higher the dividend yield but the less the company has in cash to build for future growth.
Carmike Cinemas has a dividend yield of 2.0% based upon an indicated dividend of $0.70 per share ($0.70 ÷ $35.20). Carmike has just paid its second quarterly dividend after a long period of reorganization and a recent secondary stock offering. While most companies do not start paying a cash dividend unless they are confident of their ability to continue to do so in the future, a longer track record is a desirable feature.
The rule of thumb screen totals the three ratios and looks for companies with a high value. The three ratios are highly interrelated. A firm with an earnings yield of 5% that pays no dividend would need a ratio of earnings retained to book value of at least 20% to qualify with the desired score of 25%.
The 50 companies with the highest Fundamental Rule of Thumb score are tracked and presented on AAII.com, however, only the top 25 are displayed in Table 2 due to space restrictions.
As indicated in Table 2, Carmike passed the screen with an 81.4% Fundamental Rule of Thumb score. However, a one-time tax credit boosted Carmikes score. Substituting the historical earnings per share figure with the I/B/E/S consensus expected earnings figure of $2.73 would result in a lower earnings yield (7.8% versus 29.2%), a lower ratio of earnings retained to book value (10.6% versus 50.1%), and an overall score of 20.4% versus 81.4%. A score of 20.4% is good, but below the desired 25% benchmark for the screen.
The Fundamental Rule of Thumb screen has performed well, but it tends to turn up troubled and neglected small to mid-sized companies that require careful, in-depth analysis. All screens represent starting points in the stock selection process, but screens that highlight deep-discount stocks require extra diligence to build profitable portfolios. Many investors would be wise to steer clear of these stocks unless they are able to fully understand the accounting, legal and industry factors impacting these companies. Of course, it is this type of neglect that can lead to mispriced stocks and buying opportunities.
