Should You Be Tempted To Sell Innospec Inc (NASDAQ:IOSP) At Its Current PE Ratio?

Micheal Lombardo

Innospec Inc (NASDAQ:IOSP) is currently trading at a trailing P/E of 27.3x, which is higher than the industry average of 17.7x. 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. In this article, 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 Innospec

Breaking down the P/E ratio

NasdaqGS:IOSP PE PEG Gauge May 14th 18

The P/E ratio is one of many ratios used in 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 IOSP

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

IOSP Price-Earnings Ratio = $75.25 ÷ $2.758 = 27.3x

The P/E ratio itself doesn’t tell you a lot; however, it becomes very insightful when you compare it with other similar companies. Our goal is to compare the stock’s P/E ratio to the average of companies that have similar attributes to IOSP, such as company lifetime and products sold. A common peer group is companies that exist in the same industry, which is what I use. At 27.3x, IOSP’s P/E is higher than its industry peers (17.7x). This implies that investors are overvaluing each dollar of IOSP’s earnings. Therefore, according to this analysis, IOSP is an over-priced stock.

Assumptions to watch out for

Before you jump to the conclusion that IOSP should be banished from your portfolio, it is important to realise that our conclusion rests on two assertions. The first is that our “similar companies” are actually similar to IOSP, or else the difference in P/E might be a result of other factors. For example, if you compared lower risk firms with IOSP, 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 IOSP to are fairly valued by the market. If this does not hold true, IOSP’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 IOSP. 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.
