# Does Aptech Limited’s (BOM:532475) PE Ratio Signal A Buying Opportunity?

I am writing today to help inform people who are new to the stock market and want to better understand how you can grow your money by investing in Aptech Limited (BOM:532475).

Aptech Limited (BOM:532475) trades with a trailing P/E of 32.8x, which is lower than the industry average of 36.9x. While this makes 532475 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 explain what the P/E ratio is as well as what you should look out for when using it.

### Breaking down the Price-Earnings ratio

A common ratio used for relative valuation is the P/E ratio. 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.

Formula

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

P/E Calculation for 532475

Price per share = ₹270.3

Earnings per share = ₹8.24

∴ Price-Earnings Ratio = ₹270.3 ÷ ₹8.24 = 32.8x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. Ideally, we want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as 532475, 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. 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 532475’s P/E of 32.8x is lower than its industry peers (36.9x), it means that investors are paying less than they should for each dollar of 532475’s earnings. As such, our analysis shows that 532475 represents an under-priced stock.

### Assumptions to watch out for

While our conclusion might prompt you to buy 532475 immediately, there are two important assumptions you should be aware of. The first is that our peer group actually contains companies that are similar to 532475. 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 532475, then 532475’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 532475. In this case, 532475’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 532475 to are fairly valued by the market. If this assumption does not hold true, 532475’s lower P/E ratio may be because firms in our peer group are being overvalued by the market.

### What this means for you:

Since you may have already conducted your due diligence on 532475, the undervaluation of the stock may mean it is a good time to top up on your current holdings. But at the end of the day, keep in mind that relative valuation relies heavily on critical assumptions I’ve outlined above. 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.
