In several long-term studies, however, the P/S ratio has proved a better predictor of stock returns. Perhaps that's because earnings are far more volatile than sales, and the P/E ratio can mislead when earnings are temporarily suppressed or inflated. Or, it might be related to research showing that profit margins tend to revert to industry averages over long time periods, as extraordinarily profitable companies attract new competition, and as companies with weak margins come under shareholder pressure to make improvements.
Among the large, American companies that make up the S&P 500 index, the median P/S ratio is 1.5.

For mass merchants, the median P/S ratio is 0.5. For software developers, it's 3.5. (more)
