# Should You Buy Billington Holdings Plc (AIM:BILN) At This PE Ratio?

Billington Holdings Plc (AIM:BILN) is currently trading at a trailing P/E of 9.5x, which is lower than the industry average of 13x. While this makes BILN 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. See our latest analysis for BILN

### Breaking down the Price-Earnings 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 pound of the companyâ€™s earnings.

P/E Calculation for BILN

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

BILN Price-Earnings Ratio = 2.72 Ã· 0.286 = 9.5x

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. We preferably want to compare the stockâ€™s P/E ratio to the average of companies that have similar features to BILN, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what Iâ€™ll do. At 9.5x, BILNâ€™s P/E is lower than its industry peers (13x). This implies that investors are undervaluing each dollar of BILNâ€™s earnings. Therefore, according to this analysis, BILN is an under-priced stock.

### Assumptions to be aware of

Before you jump to the conclusion that BILN 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 BILN. If this isnâ€™t the case, the difference in P/E could be due to other factors. For example, if you compared higher growth firms with BILN, then its P/E would naturally be lower since investors would reward its peersâ€™ higher growth with a higher price. The second assumption that must hold true is that the stocks we are comparing BILN to are fairly valued by the market. If this does not hold true, BILNâ€™s lower P/E ratio may be because firms in our peer group are overvalued by the market.

### What this means for you:

Are you a shareholder? 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 BILN. 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.

Are you a potential investor? If BILN has been on your watch list for a while, it is best you also consider its intrinsic valuation. Looking at PE on its own will not give you the full picture of the stock as an investment, so I suggest you should also look at other relative valuation metrics like EV/EBITDA or PEG.

PE is one aspect of your portfolio construction to consider when holding or entering into a stock. But it is certainly not the only factor.
