P/S Ratio Historical Chart

How to Read P/S Ratio History

The price-to-sales ratio compares a company's market cap to its trailing twelve-month revenue. Unlike P/E, it works for companies with no earnings — early-stage growth companies, cyclical businesses at a trough, or any firm temporarily unprofitable — making it one of the most widely used multiples in growth investing.

A stock's current P/S tells you today's implied multiple. Its 7-year history tells you whether the market is paying a premium or a discount relative to what it has historically demanded for the same business. Trading well below the 7-year average often signals a buying opportunity; trading near the 7-year high warrants scrutiny of whether the revenue growth assumptions embedded in the price are achievable.

One key caveat: a low P/S is only attractive if the business has a path to profitability. A company with persistently thin margins trading at 1× sales may be cheaper than a high-margin SaaS business at 10× sales. Always pair P/S history with margin trends and use the P/S ratio calculator or a full DCF model for context.

The orange dashed line shows the sector ETF's current P/S as a market-context anchor. If the stock trades at a significant discount to its own history and to its sector, the asymmetry is worth investigating further.
