Investment Performance of Common Stocks in Relation to Their Price-earnings Ratios: A Test of The Efficient Market Hypothesis

Core Idea:

Basu examines the relationship between stock returns and P/E ratios based on sample from 1957 to 1971. He finds that the Low P/E ratio portfolio earned 7% higher returns than a high P/E portfolio.

  • Stocks are sorted into five equally weighted portfolios based on P/E ratios (A=highest P/E, B,C,D and E=lowest P/E). The table below shows that the highest earnings yield quintile (E) earned 16.30% on average per year compared to 9.34% by the lowest quintile (A), about 7% higher.
  • Beta could not explain these return differences; in fact, the low P/E portfolios were associated with lower levels of systematic risk than the high P/E portfolios.

Alpha Highlight:

The results are hypothetical results and are NOT an indicator of future results and do NOT represent returns that any investor actually attained. Indexes are unmanaged, do not reflect management or trading fees, and one cannot invest directly in an index. Additional information regarding the construction of these results is available upon request.
