Investors generally rely on various ratios while hand-picking value stocks, as a single ratio can’t conclusively indicate the likely future performance of a stock. However, each ratio helps an investor to know a particular aspect of the company’s business. One such ratio, Price-to-Sales, can do wonders if used properly in picking stocks. 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 you're 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 you need to pay less than a dollar for a dollar’s worth. In terms of comparison, a stock with a lower Price-to-Sales ratio is more suitable for investment versus a stock with a high Price-to-Sales ratio. While Price-to-Earnings ratio is the most commonly used valuation metric, the use of Price-to-Sales ratio becomes more relevant when valuing companies that are suffering losses or are in the early cycle of development, generating little or no profits. Further, a loss making company may lose investors’ attention with a negative Price-to-Earnings ratio, but its Price-to-Sales could indicate the hidden strength in the business. Though an underrated ratio, Price-to-Sales is used to identify recovery situations or to ensure that a company's growth has not become overvalued. Apart from this, Price-to-Sales is often preferred over Price-to-Earnings, as a company’s earnings are subject to accounting estimates and management manipulation but its sales figures are assumed to be reliable. However, one should keep in mind that a company with high debt and low P/S metric is not an ideal investment. 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 the P/S ratio. Therefore, the Price-to-Sales ratio used in isolation can’t do the trick. One should also analyze other ratios like Price/Earnings, Price/Book, Debt/Equity before arriving at any investment decision.
