Demystifying the P/E ratio

P/E is often used for relative valuation since earnings power is a chief driver of investment value. 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 STT

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

STT Price-Earnings Ratio = $99.65 ÷ $5.857 = 17x

On its own, the P/E ratio doesn’t tell you much; however, it becomes extremely useful when you compare it with other similar companies. We preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to STT, such as capital structure and profitability. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. At 17x, STT’s P/E is higher than its industry peers (16.5x). This implies that investors are overvaluing each dollar of STT’s earnings. As such, our analysis shows that STT represents an over-priced stock.

A few caveats

Before you jump to the conclusion that STT 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 STT. 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 STT, 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 STT to are fairly valued by the market. If this does not hold, there is a possibility that STT’s P/E is lower because our peer group is overvalued by the market.

What this means for you:

Are you a shareholder? If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to rebalance your portfolio and reduce your holdings in STT. But keep in mind that the usefulness of relative valuation depends on whether you are comfortable with making the assumptions I mentioned above.

Are you a potential investor? If you are considering investing in STT, 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.
