China Best Group Holding Limited (SEHK:370) trades with a trailing P/E of 24.3x, which is lower than the industry average of 26.4x. While this makes 370 appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. Today, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. View our latest analysis for China Best Group Holding

### Breaking down the Price-Earnings ratio

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.

Formula

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

P/E Calculation for 370

Price per share = HK\$0.08

Earnings per share = HK\$0.003

∴ Price-Earnings Ratio = HK\$0.08 ÷ HK\$0.003 = 24.3x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Ultimately, our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to 370, 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 it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different.

Since 370’s P/E of 24.3x is lower than its industry peers (26.4x), it means that investors are paying less than they should for each dollar of 370’s earnings. As such, our analysis shows that 370 represents an under-priced stock.

### Assumptions to be aware of

However, before you rush out to buy 370, it is important to note that this conclusion is based on two key assumptions. The first is that our peer group actually contains companies that are similar to 370. If this isn’t the case, the difference in P/E could be due to some other factors. For example, if you are inadvertently comparing lower risk firms with 370, then 370’s P/E would naturally be lower than its peers, since investors would value those with lower risk with a higher price. The other possibility is if you were accidentally comparing higher growth firms with 370. In this case, 370’s P/E would be lower since investors would also reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing 370 to are fairly valued by the market. If this assumption does not hold true, 370’s lower P/E ratio may be because firms in our peer group are being 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 undervaluation could signal a good buying opportunity to increase your exposure to 370. 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. Remember that basing your investment decision off one metric alone is certainly not sufficient. There are many things I have not taken into account in this article and the PE ratio is very one-dimensional.
