What Is Price-To-Sales (P/S) Ratio And How Do I Use It?

Описание: If you've ever felt overwhelmed by the "alphabet soup" of financial ratios, this episode is your secret decoder ring for one of the most powerful, yet deceptively simple, valuation tools available. Unlike the classic P/E ratio, the P/S ratio works even for fast-growing startups and biotech firms that aren't profitable yet.


In this deep dive, we break down the fundamental formula—Market Cap divided by Annual Revenue—and explain why context is everything when comparing a retail chain to a high-growth software giant. You’ll learn how to spot "financial engineering" red flags, how growth investors use "P/S contraction" to find entry points, and why the ratio is a vital "lie detector" for cyclical industries like semiconductors.


The P/S ratio is a compass, not a full map; it tells you where to look, but you still have to do the homework. What other seemingly simple pieces of information have you been overlooking that could give you a significant edge in your trading?

Key Takeaways

• The "Unprofitable" Workhorse: The P/S ratio is uniquely valuable for companies with zero or negative earnings (where P/E ratios fail), such as early-stage tech, biotech, or companies reinvesting every penny into growth.
• Industry Context is Mandatory: There is no "magic number." A healthy P/S for a grocery chain might be under 2, while a disruptive software firm could justify a P/S of 15. Always compare a company against its direct industry peers.
• Spotting Value Traps: A low P/S ratio isn't always a bargain; it could be a "value trap" if the market expects sales to fall or margins to be crushed. You must pair P/S with Net Profit Margins to see the quality of the sales.
• Financial Engineering Warning: A rising P/S ratio without sales growth can signal trouble. It can be artificially inflated by stock dilution (increasing Market Cap) or by a stock price that remains high while revenue "falls off a cliff".
• The P/S Contraction Strategy: Growth investors look for "P/S contraction"—when a company’s sales grow faster than its stock price. This suggests the company is "growing into its valuation," often creating an attractive entry point.

"The P/E ratio is useless if there's no 'E.' But every company has sales. The P/S ratio is the precision tool for spotting overvalued hype and quiet, undervalued sleepers before the crowd piles in."
