Earnings yield
What is Earnings yield?
Earnings yield is earnings per share divided by share price, or common earnings divided by equity market value, and is the inverse of a positive P/E ratio.
Why earnings yield is used
Expressing earnings as a percentage of price makes valuation easier to compare with yields and required returns, although accounting earnings are not bond coupons or cash distributions. The measure can be trailing, forward, reported, or adjusted. It is useful for portfolio aggregation because extreme high P/E values become small yields, but negative earnings still require careful treatment.
How it is calculated
Divide earnings attributable to common shareholders by common equity market value, or diluted EPS by price. A P/E of 20 times corresponds to a 5% earnings yield. The inverse relationship holds only for a consistent, positive denominator. Do not invert a ratio marked not meaningful or average company P/E ratios to derive a portfolio yield.
Example
A stock at $50 with trailing EPS of $4 has an 8% trailing earnings yield. If forward EPS is forecast at $5, forward yield is 10%. The higher forward figure depends on forecast delivery. Neither means shareholders will receive 8% or 10% in cash because earnings may be reinvested or differ from cash flow.
How to interpret it
Compare with expected growth, return on capital, balance-sheet risk, cash conversion, and a suitable required return. A gap over government yield is sometimes called an earnings-yield spread, but it is not directly equivalent to a credit spread. Equity earnings are uncertain, subordinated, and potentially growing, while bond payments have a contractual schedule.
Limitations
Earnings reflect accounting judgments and capital structure, and can be negative or cyclically inflated. Cross-company definitions of adjusted earnings vary. Comparing earnings yield with interest rates without accounting for growth and risk can mislead. Portfolio-level aggregation should use total earnings divided by total market value rather than an unweighted average of security yields.
Practical checklist
Label trailing or forward and reported or adjusted basis, use diluted shares, normalize one-offs and cycles, and preserve negative earnings rather than truncating them. Reconcile earnings with free cash flow and returns on capital. For portfolio calculations, aggregate numerator and denominator consistently and avoid presenting earnings yield as a guaranteed cash return.
