The P/E ratio is one of many ratios used in relative valuation. It compares a stock’s price per share to the stock’s earnings per share. A more intuitive way of understanding the P/E ratio is to think of it as how much investors are paying for each pound of the company’s earnings.

P/E Calculation for WEIR

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

WEIR Price-Earnings Ratio = £22.81 ÷ £0.303 = 75.2x

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 WEIR, 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. Since WEIR’s P/E of 75.2x is higher than its industry peers (22.5x), it means that investors are paying more than they should for each dollar of WEIR’s earnings. As such, our analysis shows that WEIR represents an over-priced stock.

Assumptions to watch out for

Before you jump to the conclusion that WEIR should be banished from your portfolio, it is important to realise that our conclusion rests on two assertions. The first is that our “similar companies” are actually similar to WEIR, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with WEIR, 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 WEIR to are fairly valued by the market. If this does not hold, there is a possibility that WEIR’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 overvaluation could signal a potential selling opportunity to reduce your exposure to WEIR. 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 WEIR, basing your decision on the PE metric at one point in time is certainly not sufficient. I recommend you do additional analysis by looking at its intrinsic valuation and using other relative valuation ratios like PEG or EV/EBITDA.

PE is one aspect of your portfolio construction to consider when holding or entering into a stock. But it is certainly not the only factor.
