Should You Buy MagnaChip Semiconductor Corporation (NYSE:MX) At This PE Ratio?

Hector Vargas

MagnaChip Semiconductor Corporation (NYSE:MX) is trading with a trailing P/E of 8.7x, which is lower than the industry average of 24.6x. While MX might seem like an attractive stock to buy, it is important to understand the assumptions behind the P/E ratio before you make any investment decisions. Today, I will explain what the P/E ratio is as well as what you should look out for when using it. See our latest analysis for MagnaChip Semiconductor

Demystifying the P/E ratio

NYSE:MX PE PEG Gauge May 31st 18

P/E is often used for relative valuation since earnings power is a chief 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 MX

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

MX Price-Earnings Ratio = $11.25 ÷ $1.29 = 8.7x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful 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 MX, such as size and country of operation. A common peer group is companies that exist in the same industry, which is what I use. MX’s P/E of 8.7x is lower than its industry peers (24.6x), which implies that each dollar of MX’s earnings is being undervalued by investors. Therefore, according to this analysis, MX is an under-priced stock.

A few caveats

However, before you rush out to buy MX, it is important to note that this conclusion is based on two key assumptions. The first is that our “similar companies” are actually similar to MX, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with MX, then investors would naturally value it at a lower price since it is a riskier investment. The second assumption that must hold true is that the stocks we are comparing MX to are fairly valued by the market. If this is violated, MX’s P/E may be lower than its peers as they are actually overvalued by investors.

What this means for you:

Since you may have already conducted your due diligence on MX, 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.
