# Should You Be Tempted To Buy Bank of Hawaii Corporation (BOH) Because Of Its PE Ratio?

Bank of Hawaii Corporation (NYSE:BOH) trades with a trailing P/E of 18.8x, which is lower than the industry average of 13.9x. While BOH 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. In this article, I will deconstruct the P/E ratio and highlight what you need to be careful of when using the P/E ratio. Check out our latest analysis for Bank of Hawaii

### Breaking down the P/E ratio

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. By comparing a stockâ€™s price per share to its earnings per share, we are able to see how much investors are paying for each dollar of the companyâ€™s earnings.

Formula

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

P/E Calculation for BOH

Price per share = 81.23

Earnings per share = 4.31

âˆ´ Price-Earnings Ratio = 81.23 Ã· 4.31 = 18.8x

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. Ultimately, our goal is to compare the stockâ€™s P/E ratio to the average of companies that have similar attributes to BOH, 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. Since it is expected that similar companies have similar P/E ratios, we can come to some conclusions about the stock if the ratios are different.

At 18.8x, BOHâ€™s P/E is higher than its industry peers (13.9x). This implies that investors are overvaluing each dollar of BOHâ€™s earnings. As such, our analysis shows that BOH represents an over-priced stock.

### Assumptions to watch out for

Before you jump to the conclusion that BOH represents the perfect buying opportunity, it is important to realise that our conclusion rests on two important assertions. The first is that our peer group actually contains companies that are similar to BOH. If this isnâ€™t the case, the difference in P/E could be due to some other factors. For example, if you accidentally compared higher growth firms with BOH, then BOHâ€™s P/E would naturally be lower since investors would reward its peersâ€™ higher growth with a higher price. Alternatively, if you inadvertently compared less risky firms with BOH, BOHâ€™s P/E would again be lower since investors would reward its peersâ€™ lower risk with a higher price as well. The second assumption that must hold true is that the stocks we are comparing BOH to are fairly valued by the market. If this assumption is violated, BOH's P/E may be lower than its peers because its peers are actually overvalued by investors.

### What this means for you:

Are you a shareholder? 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 BOH 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.

Are you a potential investor? If you are considering investing in BOH, looking at the PE ratio on its own is not enough to make a well-informed decision. You will benefit from looking at additional analysis and considering its intrinsic valuation along with other relative valuation metrics like PEG and EV/Sales.
