Value Factors

Price-to-Sales

In the original edition of 'What works on Wall Street', O'Shaughnessy wrote that the single-best value factor was a company's price-to-sales ratio (P/S). In his latest edition the P/S continues to perform well, but it was unseated by the value composites and EBITDA/EV due to 2 reasons: (1) A broader scope of analysis by using deciles and (2) two very bad years for P/S, e.g. 2007 and 2008.

A stock's P/S is similar to its P/E ratio, but it measures the price of the company against its annual sales instead of earnings.

It's calculated as follows:

Price-to-Sales Ratio = Market Cap Net Sales or Revenues

In the scorecard, we show the P/S for the selected stock. We also calculate the median P/S for all stocks, the company's sector, industry group and industry. Finally, we include the percentile so you can easily compare a company to its peers. For more information, click here.
