What you need to know about the P/E ratio

NasdaqGS:ASYS PE PEG Gauge October 4th 18

The P/E ratio is one of many ratios used in relative valuation. 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.

P/E Calculation for ASYS

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

ASYS Price-Earnings Ratio = $5.14 ÷ $1.475 = 3.5x

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 ASYS, 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 ASYS’s P/E of 3.5 is lower than its industry peers (20.4), it means that investors are paying less for each dollar of ASYS’s earnings. This multiple is a median of profitable companies of 24 Semiconductor companies in US including ARISE Technologies, Daqo New Energy and Micron Technology. One could put it like this: the market is pricing ASYS as if it is a weaker company than the average company in its industry.

Assumptions to be aware of

However, there are two important assumptions you should be aware of. Firstly, our peer group contains companies that are similar to ASYS. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with ASYS, then its P/E would naturally be lower than its peers, as investors would value those with lower risk at a higher price. The second assumption that must hold true is that the stocks we are comparing ASYS to are fairly valued by the market. If this does not hold true, ASYS’s lower P/E ratio may be because firms in our peer group are overvalued by the market.

What this means for you:

If your personal research into the stock confirms what the P/E ratio is telling you, it might be a good time to add more of ASYS to your portfolio. But keep in mind that the usefulness of relative valuation depends on whether you are comfortable with making the assumptions I mentioned 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.
