# Why the P/S Ratio is My Favorite Valuation Metric

This week, I'm going to focus on the Price to Sales ratio for finding great stocks at great values.

The Price to Sales ratio is a great valuation metric. And given the recent run-up in stocks, value, to me, is becoming more and more important.

In fact, aside from the Zacks Rank, if I could only use one item to screen and pick stocks with, this item would be the one.

Definition

The Price to Sales ratio is simply: Price divided by Sales

If the Price to Sales ratio is 1, that means you're paying \$1 for every \$1 of sales the company makes.

A price to sales ratio of 2 means you're paying \$2 for every \$1 of sales the company makes.

As you might have guessed, the lower the Price the Sales ratio, the better.

A price to Sales ratio of .5 means you're paying 50 cents for every \$1 of sales the company makes.

And paying less than a dollar for a dollar's worth of something is a good bargain.

One of the reasons I like the Price to Sales ratio is because it looks at sales rather than earnings, like the P/E ratio does.

And sales are harder to manipulate on an income statement than earnings.

Secondly, I'd be hard pressed to find a screen where adding the Price to Sales ratio didn't improve it.

Price to Sales Study

For me, I prefer to look for stocks with a Price to Sales ratio under 1. Although, I'm willing to go up to 4, depending on the industry.

But in my testing, as the illustration below shows, those with a Price to Sales ratio of 1 or less produced the best returns. Between 1 and 2 also outperformed pretty significantly. But once you got over 4, the odds were against you.

• P/S range greater than or equal to 0 and less than or equal to 1:
Average Annual Return: 17.8%

• P/S range greater than 1 and less than or equal to 2: Average Annual Return: 11.1%
• P/S range greater than 2 and less than or equal to 3: Average Annual Return: 7.3%
• P/S range greater than 3 and less than or equal to 4: Average Annual Return: 3.8%
• P/S range greater than 4: Average Annual Return: -7.9%

But the best way to use it, I've found, is to find stocks with a Price to Sales ratio below the median for its Industry.

And that's what we'll be focusing on in this week's screen.
