Free Cash Yield: The Best Valuation Statistic?
In fundamental stock analysis, there are a number of valuation statistics, many of which have been discussed on this blog before. The most popular, of course, is the price-to-earnings ratio, or P/E. This ratio is easily calculated and can be found almost anywhere you can find a stock price. But is it really the single best valuation statistic to use to determine quickly whether a company may be undervalued?
First, the benefits. As mentioned, P/E is easily accessible. Second, it is a good point of comparison. If a stock's P/E ratio is lower than the overall market's, lower than it's primary competitors, and lower than the specific stock's historical average, the stock is likely to be undervalued and warrants additional inspection.
But there are drawbacks to the P/E ratio as well. First, P/E can be widely skewed by one time charges or benefits. For example, if a company sells off a portion of it's business, the gain on the sale is recorded as earnings, raising the "E" portion of the ratio and bringing the overall P/E down. If we don't dig deeper to ensure that the P/E ratio we're comparing against competitors, the market, and historical average represents an accurate number for the core business, we can be fooled into thinking it's undervalued.
Second, P/E includes charges and benefits not related to the core business. Non-operating income and charges such as interest paid on cash and investments, other investment gains and losses, income taxes, and other items are included in the P/E. Since these can vary considerably between companies, but have no bearing on how good or bad the business itself is, they can skew the ratio, making comparisons with competitors less than perfect.
Joel Greenblatt provides us with a similar, but better, statistic in The Little Book that Beats the Market: Earnings Yield. In essence, earnings yield simply flips the P/E ratio upside down, making the ratio into a percentage. For example, a 15 P/E becomes a 6.7% earnings yield. Turning P/E into a yield percentage is useful, because we can then compare it against bond or treasury yields. The current yield on a 10 year treasury is about 3.5%, so the stock would appear to give us 3.2% extra return for the risk involved.
But Mr. Greenblatt goes farther with his version of the earnings yield. For "E" portion in his version refers to operating earnings. Operating earnings are also known as EBIT - earnings before interest and taxes, which strips out the non-operating costs and revenue from the result, allowing for a more meaningful comparison between companies. The "P" portion refers to Enterprise Value. Enterprise value is simply market capitalization (the price the market has put on the company, or share price times number of shares), plus debt, minus cash on hand. By making these changes, Greenblatt incorporates balance sheet risk (or lack of) into his earnings yield calculation, while making it a better comparison between companies and against treasury and bond yields. Clearly, his version of earnings yield is a better metric than straight P/E.
One problem remains... earnings as reported is not always a tangible figure. A lot of assumptions are used by accountants to come up with earnings figures. First, they must decide what is actually a sale - some customers may never pay, and contracts can always be renegotiated or canceled, even after being reported as revenue in the income statement. Also, income statements include assumptions for such things as depreciation of property and equipment, the eventual value of stock options granted, and so forth.
This is why the cash flow statement exists. A company can use accounting tricks to fake earnings, but cold hard cash is harder to fake - the company either collected it or it didn't. What's more, the true value of a business is simply the discounted sum of all future cash flows, according to accepted finance theory. So, cash earned is clearly a better measure of business performance than earnings. Free cash flow is a step better, as it subtracts out the costs the company must pay to keep the business operating (such as equipment repairs, computer replacements, etc). MagicDiligence uses the depreciation figure to approximate these costs.
Once we have the free cash flow figure, we simply plug that in as the "E" portion of Greenblatt's earnings yield equation, and we have free cash flow yield. This is a powerful figure - it measures a company's cash generation, balance sheet risk, and share price all at once, and allows a meaningful comparison against both other stocks and fixed income assets like bonds and t-bills. No other valuation statistic gives you this much relevant information.
For those who are lost, I'll run through a simple example using my favorite lab rat - Johnson & Johnson (JNJ). To calculate earnings yield, here are the values you need from the 10-K. They've been gathered for this example:
- Net Cash from Operations (Cash Flow Statement)
- Depreciation and Amortization (Cash Flow Statement)
- Cash and Short-term Investments (Balance Sheet)
- Long-term Debt (Balance Sheet)
- Diluted Shares Outstanding (usually in the Income Statement, although sometimes you need to look in the footnotes).
- Current share price (Yahoo! or wherever)
The values from the last 10-K are (in millions):
- 9,315 (7,770 cash + 1,545 short-term investments)
First, we calculate free cash flow by subtracting depreciation from net cash earned:
- Free cash flow = (15,249 - 2,777) = 12,472
Next, we calculate enterprise value. First calculate market capitalization by multiplying share price by number of shares. Then add debt and subtract cash and short-term investments to that figure:
- Market Cap = (64.88 * 2910.70) = 189,000
- Enterprise Value = (189,000 + 7,074 - 9,315) = 186,759
Free cash yield is then FCF/EV, or:
- Free cash yield = 12,472 / 186,759 = 6.68%
This seems like a fair premium to the low treasury bill rate, for such a quality company. Stocks get into real bargain territory when free cash yield approaches 10% but remember, fundamental analysis is needed before putting your hard earned money into the stock. That's what MagicDiligence is here for!
