How is free cash flow yield calculated and why is it preferred over earnings yield for screening?

Free cash flow yield measures the free cash flow generated per dollar of market value (or enterprise value), and many analysts consider it a superior metric to earnings yield.

Calculation:

FCF Yield (Equity) = Free Cash Flow to Equity / Market Capitalization

FCF Yield (Firm) = Free Cash Flow to Firm / Enterprise Value

Example — Pemberton Manufacturing:

For comparison, Pemberton's P/E is 18x (earnings yield = 5.6%). The FCF yield of 12.6% is more than double the earnings yield — signaling the stock may be cheaper than P/E suggests.

Why FCF Yield Beats Earnings Yield:

1. Harder to manipulate: Earnings are accrual-based and subject to accounting choices (depreciation methods, revenue recognition, one-time items). Cash flow is more objective.

1. Captures capex intensity: A company with high earnings but massive reinvestment needs generates little free cash. Earnings yield overstates the actual cash available to shareholders.

1. Cross-sector comparability: Capital-intensive sectors (telecom, utilities, manufacturing) often show misleading P/E ratios due to high depreciation. FCF yield normalizes for this.

1. Better predictor of returns: Academic research shows FCF yield is a stronger predictor of future stock returns than earnings yield, particularly for value strategies.

When Earnings Yield is Better:

• Companies with lumpy capex (FCF can be negative in heavy investment years)
• High-growth companies where capex drives future value creation
• Financial companies where FCF is not meaningfully defined

Screening Application:

Stocks with FCF yield above 8% and simultaneously P/E above 15x often indicate that the market is penalizing the stock for reported earnings issues that don't reflect cash generation — a potential opportunity.
