Though Price-to-Earnings is the first thing to cross one’s mind while using valuation metrics, Price-to-Sales has emerged as a convenient tool to determine the value of stocks that are incurring losses or are in an early cycle of development, generating meager or no profits.

While a loss-making company with a negative Price-to-Earnings ratio falls out of investor favor, its Price-to-Sales could indicate the hidden strength of its business. This underrated ratio is also used to identify a recovery situation or ensure that a company’s growth is not overvalued.

A stock’s Price-to-Sales ratio reflects how much investors are paying for each dollar of revenues generated by the company.

If the Price-to-Sales ratio is 1, it means that investors are paying $1 for every $1 of revenues generated by the company. So, it goes without saying that a stock with Price-to-Sales below 1 is a good bargain, as investors need to pay less than a dollar for a dollar’s worth.  

Thus, a stock with a lower Price-to-Sales ratio is more suitable for investment versus a stock with a high Price-to-Sales ratio.

Price-to-Sales is often preferred over Price-to-Earnings as companies can manipulate their earnings using various accounting measures. However, sales are harder to manipulate and are relatively reliable.

However, one should keep in mind that a company with high debt and low Price-to-Sales is not an ideal choice. The high debt level will have to be paid off at some point, leading to further share issuance and a rise in market cap and ultimately a higher Price-to-Sales ratio.

In any case, the Price-to-Sales ratio used in isolation can’t do the trick. One should also analyze other ratios like Price/Earnings, Price/Book and Debt/Equity before arriving at any investment decision.
