# Should You Be Tempted To Buy SAP SE (FRA:SAP) Because Of Its PE Ratio?

SAP SE (DB:SAP) is currently trading at a trailing P/E of 27.9x, which is lower than the industry average of 36.9x. While SAP 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 SAP

### Breaking down the P/E ratio

The P/E ratio is one of many ratios used in relative valuation. It compares a stockâ€™s price per share to the stockâ€™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 companyâ€™s earnings.

P/E Calculation for SAP

Price-Earnings Ratio = Price per share Ã· Earnings per share

SAP Price-Earnings Ratio = â‚¬98.12 Ã· â‚¬3.517 = 27.9x

On its own, the P/E ratio doesnâ€™t tell you much; however, it becomes extremely useful when you compare it with other similar companies. Our goal is to compare the stockâ€™s P/E ratio to the average of companies that have similar attributes to SAP, such as company lifetime and products sold. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. SAPâ€™s P/E of 27.9x is lower than its industry peers (36.9x), which implies that each dollar of SAPâ€™s earnings is being undervalued by investors. Therefore, according to this analysis, SAP is an under-priced stock.

### A few caveats

Before you jump to the conclusion that SAP is the perfect buying opportunity, it is important to realise that our conclusion rests on two assertions. Firstly, our peer group contains companies that are similar to SAP. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you compared lower risk firms with SAP, 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 SAP to are fairly valued by the market. If this is violated, SAPâ€™s P/E may be lower than its peers as they are actually overvalued by investors.

### 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 SAP. 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.
