# Is It Time To Sell ACNB Corporation (NASDAQ:ACNB) Based Off Its PE Ratio?

ACNB Corporation (NASDAQ:ACNB) trades with a trailing P/E of 17.8x, which is higher than the industry average of 16.9x. Although some investors may jump to the conclusion that you should avoid the stock or sell if you own it, understanding the assumptions behind the P/E ratio might change your mind. Today, I will break down what the P/E ratio is, how to interpret it and what to watch out for. See our latest analysis for ACNB

### Demystifying the P/E ratio

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

P/E Calculation for ACNB

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

ACNB Price-Earnings Ratio = \$31.6 Ă· \$1.778 = 17.8x

The P/E ratio itself doesnâ€™t tell you a lot; however, it becomes very insightful 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 ACNB, 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 ACNBâ€™s P/E of 17.8x is higher than its industry peers (16.9x), it means that investors are paying more than they should for each dollar of ACNBâ€™s earnings. As such, our analysis shows that ACNB represents an over-priced stock.

### Assumptions to watch out for

Before you jump to the conclusion that ACNB should be banished from your portfolio, it is important to realise that our conclusion rests on two assertions. The first is that our â€śsimilar companiesâ€ť are actually similar to ACNB, or else the difference in P/E might be a result of other factors. For example, if you are comparing lower risk firms with ACNB, 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 ACNB to are fairly valued by the market. If this does not hold true, ACNBâ€™s lower P/E ratio may be because firms in our peer group are overvalued by the market.

### What this means for you:

You may have already conducted fundamental analysis on the stock as a shareholder, so its current overvaluation could signal a potential selling opportunity to reduce your exposure to ACNB. 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.
