Demystifying the P/E ratio

NasdaqCM:OPNT PE PEG Gauge Oct 14th 17

A common ratio used for relative valuation is the P/E ratio. By comparing a stock’s price per share to its earnings per share, we are able to see how much investors are paying for each dollar of the company’s earnings.

P/E Calculation for OPNT

Price-Earnings Ratio = Price per share ÷ Earnings per share

OPNT Price-Earnings Ratio = 36.11 ÷ 2.912 = 12.4x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to OPNT, such as company lifetime and products sold. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. OPNT’s P/E of 12.4x is lower than its industry peers (23.5x), which implies that each dollar of OPNT’s earnings is being undervalued by investors. Therefore, according to this analysis, OPNT is an under-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to buy OPNT immediately, there are two important assumptions you should be aware of. Firstly, our peer group contains companies that are similar to OPNT. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with OPNT, then its P/E would naturally be lower than its peers, as investors would value those with lower risk at a higher price. The second assumption that must hold true is that the stocks we are comparing OPNT to are fairly valued by the market. If this does not hold, there is a possibility that OPNT’s P/E is lower because our peer group is overvalued by the market.

What this means for you:

Are you a shareholder? You may have already conducted fundamental analysis on the stock as a shareholder, so its current undervaluation could signal a good buying opportunity to increase your exposure to OPNT. Now that you understand the ins and outs of the PE metric, you should know to bear in mind its limitations before you make an investment decision.

Are you a potential investor? If you are considering investing in OPNT, looking at the PE ratio on its own is not enough to make a well-informed decision. You will benefit from looking at additional analysis and considering its intrinsic valuation along with other relative valuation metrics like PEG and EV/Sales.
