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.
A better indicator of the attractiveness of an investment which takes growth into account is the Forward Rate of Return (Yacktman) %. Corning's Forward Rate of Return (Yacktman) % for the quarter that ended in Mar. 2026 was -5.81%. The Forward Rate of Return uses the normalized Free Cash Flow of the past five years, and considers growth.
