Below 1x - low
Normal for low-margin businesses (retail, distribution) or a sign of distress. Margin context decides which.
Definition
What is the price-to-sales (P/S) ratio?
The price-to-sales (P/S) ratio is a company's market capitalization divided by its annual revenue (equivalently, share price divided by sales per share). Because it uses revenue rather than profit, it can value companies that aren't yet profitable - early-stage growth, turnarounds, or cyclicals at a trough - where the P/E ratio is negative or meaningless.

Short answer
P/S is most useful where earnings are temporarily absent or distorted. But revenue says nothing about whether it's profitable - a low P/S on a money-losing business isn't cheap. Always read it next to the net margin.
How to read the P/S ratio
1-3x - moderate
A typical range for profitable companies with average margins.
3-10x - high
Usually high-margin software or strong brands. Only justified by fat margins plus durable growth.
Above 10x - very rich
Prices years of high-margin growth. The bar for disappointment is low - any growth stumble hurts.
P/S is meaningless without margins
A software firm with a $5B market cap on $500M of revenue trades at a P/S of 10. That looks expensive - but if it earns 30 percent net margins and grows 25 percent a year, it's defensible. A grocery chain at the same P/S of 10 would be absurd: at roughly 2 percent margins it would imply a P/E in the hundreds.
The fix is simple: pair P/S with net margin. A high P/S on a high-margin business can be reasonable; the same multiple on a thin-margin one is a red flag. As margins expand or contract, the 'fair' P/S moves with them.
