The P/E ratio is one of many ratios used in relative valuation. 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 GPRE

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

GPRE Price-Earnings Ratio = $16.8 ÷ $0.836 = 20.1x

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 GPRE, 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 20.1x, GPRE’s P/E is higher than its industry peers (14.5x). This implies that investors are overvaluing each dollar of GPRE’s earnings. As such, our analysis shows that GPRE represents an over-priced stock.

Assumptions to watch out for

However, before you rush out to sell your GPRE shares, it is important to note that this conclusion is based on two key assumptions. Firstly, our peer group contains companies that are similar to GPRE. If this isn’t the case, the difference in P/E could be due to other factors. For example, if you are comparing lower risk firms with GPRE, 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 GPRE to are fairly valued by the market. If this does not hold true, GPRE’s lower P/E ratio may be because firms in our peer group are overvalued by the market.
