Is JBM Auto Limited's (NSE:JBMA) PE Ratio A Signal To Buy For Investors?

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 JBM Auto Limited (NSE:JBMA).

JBM Auto Limited (NSE:JBMA) trades with a trailing P/E of 21.7x, which is lower than the industry average of 24.7x. While this makes JBMA appear like a great stock to buy, you might change your mind after I explain the assumptions behind the P/E ratio. In this article, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. See our latest analysis for JBM Auto

Breaking down the P/E ratio

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

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 JBMA, 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 similar companies should technically have similar P/E ratios, we can very quickly come to some conclusions about the stock if the ratios differ.

JBMA’s P/E of 21.7x is lower than its industry peers (24.7x), which implies that each dollar of JBMA’s earnings is being undervalued by investors. As such, our analysis shows that JBMA represents an under-priced stock.

Assumptions to watch out for

Before you jump to the conclusion that JBMA represents the perfect buying opportunity, it is important to realise that our conclusion rests on two important assertions. The first is that our “similar companies” are actually similar to JBMA. If the companies aren’t similar, the difference in P/E might be a result of other factors. For example, if you accidentally compared higher growth firms with JBMA, then JBMA’s P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. Alternatively, if you inadvertently compared less risky firms with JBMA, JBMA’s P/E would again be lower since investors would reward its peers’ lower risk with a higher price as well. The second assumption that must hold true is that the stocks we are comparing JBMA to are fairly valued by the market. If this assumption does not hold true, JBMA’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 JBMA, 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.
