The P/E ratio is one of many ratios used in relative valuation. 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 981

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

981 Price-Earnings Ratio = $1.2 ÷ $0.052 = 22.9x

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 981, 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. 981’s P/E of 22.9x is higher than its industry peers (16.1x), which implies that each dollar of 981’s earnings is being expensive by investors. Therefore, according to this analysis, 981 is an over-priced stock.

Assumptions to be aware of

Before you jump to the conclusion that 981 should be banished from your portfolio, it is important to realise that our conclusion rests on two assertions. Firstly, our peer group contains companies that are similar to 981. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you compared lower risk firms with 981, then investors would naturally value it at a lower price since it is a riskier investment. The second assumption that must hold true is that the stocks we are comparing 981 to are fairly valued by the market. If this does not hold true, 981’s lower P/E ratio may be because firms in our peer group are overpriced by the market.
