The price/sales ratio is one of the most important tools you can use to determine if the market is under or over valuing a stock’s price.
Clearly, you need to know whether a stock has any room to grow before you make an investment decision. If the stock is modestly priced relative to its industry peers and you believe it has solid growth prospects, then you have an investment candidate.
On the other hand, a wildly over-priced stock usually has only one way to go. It may still be an investment candidate, but only when the price is more attractive.
The Right Price
The price/sales ratio is one of the tools that will help you determine which category a stock is in and help you make an informed investment decision.
Stock prices tell you nothing. "X" company stock is selling for Rs. 93 and "Y" was quoted at Rs. 41. Which is the better buy considering both in the same sector? If you knew nothing about the companies, the stock prices give you no hint. Is X a better company because its stock is more expensive or is Y a good bargain?
The price/sales ratio creates a metric that allows you to compare companies in the same industries. You calculate it by dividing the market capitalization of the company by its revenue.
Market capitalization or market cap is simply the number of shares outstanding multiplied by the per share price. For example, a company with 100 million shares outstanding and a per share price of Rs 55 would have a market cap of Rs. 5.5 billion.
By dividing the market cap by revenues, you get a number that you can use to compare companies in the same industry. The lower the number, the better. It is important that you only use the price/sales ratio to compare companies in the same industry since there will be differences among industry groups.
Price/sales Ratio Reveals
Let’s take another look at "X" and "Y" stocks. Based on the quotes above, X’s price/sales ratio is 1.7, while Y's number is 2.2. For the industry group, the price/sales ratio is 2.8.
Both stocks were selling under the industry average, however looking at just the price/sales ratio stock "X" is the better value at 1.7.
One of the ways you can use price/sales ratio numbers is to check the other prime value metric, the price earnings ratio.
Continuing our example, X’s P/E is 20.1 and Y’s is 34.3. The industry group P/E is 33. According to the P/E, it appears that X's is still the better value.
If the price/sales ratio and the price/earning ratio contradict each other, that is a sign that something is up with the company’s books. Look for a one-time event that may have distorted the financials on a temporary basis.
