Is Neogen Corporation’s (NEOG) PE Ratio A Signal To Sell For Investors?

Jenifer Prater

Neogen Corporation (NASDAQ:NEOG) is trading with a trailing P/E of 65.4x, which is higher than the industry average of 43.2x. While this makes NEOG appear like a stock to avoid or sell if you own it, you might change your mind after I explain the assumptions behind the P/E ratio. 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. View our latest analysis for Neogen

Breaking down the Price-Earnings ratio

NasdaqGS:NEOG PE PEG Gauge Oct 7th 17

The P/E ratio is a popular ratio used in relative valuation since earnings power is a key driver of investment value. It compares a stock’s price per share to the stock’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 dollar of the company’s earnings.

P/E Calculation for NEOG

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

NEOG Price-Earnings Ratio = 78.74 ÷ 1.204 = 65.4x

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 preferably want to compare the stock’s P/E ratio to the average of companies that have similar features to NEOG, such as capital structure and profitability. One way of gathering a peer group is to use firms in the same industry, which is what I’ll do. At 65.4x, NEOG’s P/E is higher than its industry peers (43.2x). This implies that investors are overvaluing each dollar of NEOG’s earnings. Therefore, according to this analysis, NEOG is an over-priced stock.

Assumptions to watch out for

Before you jump to the conclusion that NEOG should be banished from your portfolio, it is important to realise that our conclusion rests on two assertions. Firstly, our peer group contains companies that are similar to NEOG. 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 NEOG, 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 NEOG to are fairly valued by the market. If this does not hold, there is a possibility that NEOG’s P/E is lower because our peer group is 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 overvaluation could signal a potential selling opportunity to reduce your exposure to NEOG. 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 you are considering investing in NEOG, 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.

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.
