P/E is a popular ratio used for relative valuation. 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 PACW

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

PACW Price-Earnings Ratio = 49.28 ÷ 2.896 = 17x

The P/E ratio isn’t a metric you view in isolation and only becomes useful when you compare it against other similar companies. We want to compare the stock’s P/E ratio to the average of companies that have similar characteristics as PACW, such as size and country of operation. A quick method of creating a peer group is to use companies in the same industry, which is what I will do. At 17x, PACW’s P/E is lower than its industry peers (18.5x). This implies that investors are undervaluing each dollar of PACW’s earnings. As such, our analysis shows that PACW represents an under-priced stock.

Assumptions to watch out for

However, before you rush out to buy PACW, it is important to note that this conclusion is based on two key assumptions. Firstly, our peer group contains companies that are similar to PACW. 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 PACW, 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 PACW to are fairly valued by the market. If this is violated, PACW's P/E may be lower than its peers as they are actually overvalued by investors.

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 PACW. 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 PACW 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.
