# Does QuinStreet, Inc.'s (NASDAQ:QNST) P/E Ratio Signal A Buying Opportunity?

This article is written for those who want to get better at using price to earnings ratios (P/E ratios). To keep it practical, we'll show how QuinStreet, Inc.'s (NASDAQ:QNST) P/E ratio could help you assess the value on offer. QuinStreet has a price to earnings ratio of 8.93, based on the last twelve months. That means that at current prices, buyers pay \$8.93 for every \$1 in trailing yearly profits.

### How Do You Calculate A P/E Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price Ã· Earnings per Share (EPS)

Or for QuinStreet:

P/E of 8.93 = \$11.25 Ã· \$1.26 (Based on the trailing twelve months to June 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### How Does QuinStreet's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. We can see in the image below that the average P/E (26.3) for companies in the interactive media and services industry is higher than QuinStreet's P/E.

Its relatively low P/E ratio indicates that QuinStreet shareholders think it will struggle to do as well as other companies in its industry classification. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. You should delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

QuinStreet's earnings made like a rocket, taking off 267% last year.

### Remember: P/E Ratios Don't Consider The Balance Sheet

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting QuinStreet's P/E?

With net cash of US\$63m, QuinStreet has a very strong balance sheet, which may be important for its business. Having said that, at 11% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Bottom Line On QuinStreet's P/E Ratio

QuinStreet's P/E is 8.9 which is below average (17) in the US market. Not only should the net cash position reduce risk, but the recent growth has been impressive. The below average P/E ratio suggests that market participants don't believe the strong growth will continue.
