Michael Crabtree

Merck & Co Inc. (NYSE:MRK) is currently trading at a trailing P/E of 107.7x, which is higher than the industry average of 23.5x. Although some investors may jump to the conclusion that you should avoid the stock or sell if you own it, understanding the assumptions behind the P/E ratio might change your mind. In this article, I will break down what the P/E ratio is, how to interpret it and what to watch out for. Check out our latest analysis for Merck

Demystifying the P/E ratio

NYSE:MRK PE PEG Gauge Jun 15th 18

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. 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.

P/E Calculation for MRK

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

MRK Price-Earnings Ratio = $62.59 ÷ $0.581 = 107.7x

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 MRK, such as size and country of operation. A common peer group is companies that exist in the same industry, which is what I use. At 107.7x, MRK’s P/E is higher than its industry peers (23.5x). This implies that investors are overvaluing each dollar of MRK’s earnings. Therefore, according to this analysis, MRK is an over-priced stock.

Assumptions to be aware of

However, before you rush out to sell your MRK shares, it is important to note that this conclusion is based on two key assumptions. Firstly, our peer group contains companies that are similar to MRK. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you compared higher growth firms with MRK, then its P/E would naturally be lower since investors would reward its peers’ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing MRK to are fairly valued by the market. If this does not hold, there is a possibility that MRK’s P/E is lower because our peer group is overvalued by the market.

What this means for you:

Since you may have already conducted your due diligence on MRK, the overvaluation of the stock may mean it is a good time to reduce 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.
