# Is It Time To Buy Morgan Stanley (NYSE:MS) Based Off Its PE Ratio?

Morgan Stanley (NYSE:MS) is currently trading at a trailing P/E of 14.3x, which is lower than the industry average of 16.2x. While this makes MS 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 explain what the P/E ratio is as well as what you should look out for when using it. Check out our latest analysis for Morgan Stanley

### Demystifying the P/E ratio

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

Price per share = \$51.4

Earnings per share = \$3.582

∴ Price-Earnings Ratio = \$51.4 ÷ \$3.582 = 14.3x

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. Ideally, we want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as MS, 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 MS’s P/E of 14.3x is lower than its industry peers (16.2x), it means that investors are paying less than they should for each dollar of MS’s earnings. As such, our analysis shows that MS represents an under-priced stock.

### A few caveats

Before you jump to the conclusion that MS represents the perfect buying opportunity, it is important to realise that our conclusion rests on two important assertions. The first is that our peer group actually contains companies that are similar to MS. 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 MS, then MS’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 MS. In this case, MS’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 MS to are fairly valued by the market. If this does not hold, there is a possibility that MS’s P/E is lower 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 MS. 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.
