Joel Greenblatt's definition of earnings yield has the same problems the regular earnings yield does. It does not consider the growth of the company. It only looks at one-year's business operation. For cyclical companies, the earnings yield is usually highest at the peak of the business cycle. But these earnings are rarely sustainable.

Insteel Industries's Forward Rate of Return (Yacktman) % for the quarter that ended in Jun. 2026 was -10.67%. The Forward Rate of Return uses the normalized Free Cash Flow of the past five years, and considers growth.
