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 dollar of the company’s earnings.

P/E Calculation for 1108

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

1108 Price-Earnings Ratio = CN¥3.03 ÷ CN¥0.023 = 129.7x

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 want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as 1108, such as size and country of operation. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. 1108’s P/E of 129.7x is higher than its industry peers (15.6x), which implies that each dollar of 1108’s earnings is being overvalued by investors. As such, our analysis shows that 1108 represents an over-priced stock.

Assumptions to watch out for

While our conclusion might prompt you to sell your 1108 shares immediately, there are two important assumptions you should be aware of. The first is that our “similar companies” are actually similar to 1108, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with 1108, 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 1108 to are fairly valued by the market. If this does not hold, there is a possibility that 1108’s P/E is lower because our peer group is overvalued by the market.

What this means for you:

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 1108. 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.
