The price-to-sales ratio compares market value to trailing revenue — useful precisely where P/E fails, because every company has sales even when it has no profit. This heatmap colors US stocks by P/S, sized by market cap and grouped by sector, revealing which parts of the market pay most for each revenue dollar.
Greener tiles trade at lower price-to-sales multiples, redder tiles at higher ones. Software routinely shows double-digit P/S while retailers sit below 1.
For unprofitable companies — early-stage tech, biotech, turnaround stories — where P/E is undefined. P/S also resists accounting manipulation better than earnings-based ratios because revenue is harder to massage than profit.
Below ~1 is traditionally cheap for mature businesses; software companies commonly trade at 5–15× sales. Always compare within a sector — the heatmap groups tiles by sector precisely for that.
Yes — low P/S with negative margins means the company sells a lot but keeps nothing. Pair P/S with the net-margin or FCF-margin heatmap to check whether revenue actually converts to profit.
