What Is Free Cash Flow Yield?

Price-to-earnings is the ratio everyone quotes, and it answers a narrow question: how many dollars of recent accounting profit you are paying for. Profit is not cash. Depreciation, working capital, and capital spending sit between the income statement and the cash that is actually left. Free cash flow yield asks about that remainder.

The formula

Free cash flow, in the definition StockWatch uses, is cash from operations minus capital expenditures. Free cash flow yield is that figure divided by market cap.

Yield = free cash flow / market cap

A company with $200 million of free cash flow and a $4 billion market cap has a 5 percent free cash flow yield. You can think of it as the cash return the whole business produced over the period you measured, compared with the price of buying the entire equity. It is not the dividend. The company may have reinvested the cash, paid down debt, or bought back stock.

Market cap is equity value. It ignores net debt. A company with a lot of debt can show a handsome equity yield while the enterprise is less cheap than it looks. When that matters, look at enterprise value beside market cap. Both are in the metrics reference.

Why it disagrees with the P/E ratio

Earnings and cash diverge for ordinary reasons:

• A business spends heavily on equipment or stores. Earnings deduct that spending slowly, through depreciation. Free cash flow deducts it when the cash leaves.
• Receivables or inventory build. Revenue is booked. Cash has not arrived.
• A one-time gain lifts net income and does nothing durable for cash from operations.

A low P/E with a weak or negative free cash flow yield is a prompt to read the cash flow statement, not a prompt to call the stock cheap. A high free cash flow yield with a high P/E can mean the opposite: accounting profit is depressed, and cash is not. Either pattern is a research lead. Neither is a conclusion.

A worked example

Suppose two companies each have a $10 billion market cap and $500 million of net income. Both have a P/E of 20.

Company A produced $700 million of cash from operations and spent $200 million on capital expenditures. Free cash flow is $500 million. Yield is 5 percent.

Company B produced $400 million of cash from operations and spent $300 million on capital expenditures. Free cash flow is $100 million. Yield is 1 percent.

Same earnings. Same price. Very different cash left after keeping the business running. A screen that only sorts on P/E will treat them as twins.

The percentages above use one period. Trailing twelve months is usually the fairer input, because a single quarter of capital spending can swing the yield. In the screener, prefer a trailing measure of free cash flow when you set a yield cutoff, and use the quarterly series when you want to see whether the yield is a streak or a spike.

How to screen with it

A yield screen needs a floor and a sanity check.

• Free cash flow yield above a number you would accept for a business of that quality. Four or five percent is a common place to start looking, not a rule of nature. The right floor depends on rates, the industry, and how stable the cash is.
• Free cash flow itself above zero, so the yield is not a quirk of a negative market cap comparison you will never actually see.
• Revenue that is not falling off a cliff. A high yield on a shrinking business is often the market saying the cash will not last. Pair the yield rule with year-over-year revenue growth above zero, or with the consistency filter described in how to screen for consistent growth.

Sort by free cash flow yield descending if the question is “what throws off the most cash relative to its price.” Sort by revenue growth if the question is “what is still growing among companies that already clear a cash hurdle.”

Build it in the screener. The field is Free Cash Flow Yield, defined as free cash flow divided by market cap. How to screen stocks is the surrounding process: one question, a few rules, then save the screen.

Read the high yields before you trust them

The top of a yield sort is where odd accounting collects. Look for:

• A year when capital spending was unusually low and is likely to rebound
• Cash from operations boosted by a working-capital release that will reverse
• A market cap that just fell because the business got worse, which mechanically raises the yield

Open the cash flow statement in the filing and compare two or three years, not the single number the screen used. How to read a 10-K after a screen is a reading order for that check. If the yield survives that read, you have a candidate. If it does not, the screen still did its job: it showed you where to look.
