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.

Westlake Chemical Partners LP's Forward Rate of Return (Yacktman) % for the quarter that ended in Jun. 2026 was 41.88%.
