The earning yield can be used to compare the earnings of a specific company or group of companies across different sectors and industries against bond yields. Generally, the earnings yields of equities are higher than the yield of risk-free
treasury bonds. Some of this may result in dividends, while some may be kept as retained earnings. The market price of stocks may increase or decrease, reflecting the additional risk involved in equity investments. The average
P/E ratio for U.S. stocks from 1900 to 2005 is 14, which equates to an earnings yield of over 7%. The
Fed model is an example of a system that uses the earnings yield as a method to assess aggregate stock market valuation levels, although it is disputed. ==Adjusted versions==
