How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Share Price ÷ Earnings per Share (EPS)

Or for Qualstar:

P/E of 19.92 = $5.52 ÷ $0.28 (Based on the year to June 2019.)

Is A High P/E Ratio Good?

The higher the P/E ratio, the higher the price tag of a business, relative to its trailing earnings. That isn't a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business's prospects, relative to stocks with a lower P/E.

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

Qualstar's P/E tells us that market participants think its prospects are roughly in line with its industry. The company could surprise by performing better than average, in the future. Further research into factors such as insider buying and selling, could help you form your own view on whether that is likely.

How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. When earnings grow, the 'E' increases, over time. And in that case, the P/E ratio itself will drop rather quickly. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Qualstar shrunk earnings per share by 64% over the 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. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

Is Debt Impacting Qualstar's P/E?

With net cash of US$4.4m, Qualstar has a very strong balance sheet, which may be important for its business. Having said that, at 41% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

The Bottom Line On Qualstar's P/E Ratio

Qualstar trades on a P/E ratio of 19.9, which is above its market average of 17.6. The recent drop in earnings per share might keep value investors away, but the net cash position means the company has time to improve: and the high P/E suggests the market thinks it will.

Investors should be looking to buy stocks that the market is wrong about. As value investor Benjamin Graham famously said, 'In the short run, the market is a voting machine but in the long run, it is a weighing machine.
