The P/E ratio can help us determine, from a valuation perspective, which of the two is cheaper. The most commonly used P/E ratios are the forward P/E and the trailing P/E. A third and less typical variation uses the sum of the last two actual quarters and the estimates of the following two quarters.

P/E ratios rely on accurately presenting the market value of shares and earnings per share estimates. Thus, it’s possible it could be manipulated, so analysts and investors have to trust the company’s officers to provide genuine information. The stock will be considered riskier and less valuable if that trust is broken.

Additionally, the Price Earnings Ratio can produce wonky results, as demonstrated below. Negative EPS resulting from a loss in earnings will produce a negative P/E. An exceedingly high P/E can be generated by a company with close to zero net income, resulting in a very low EPS in the decimals.

To reduce these risks, the P/E ratio is only one measurement analyst’s review. If a company were to manipulate its results intentionally, it would be challenging to ensure all the metrics were aligned in how they were changed. That’s why the P/E ratio continues to be a central data point when analyzing public companies, though by no means is it the only one. However, the P/E of 31 isn’t helpful unless you have something to compare it with, like the stock’s industry group, a benchmark index, or HES’s historical P/E range. Next, we can divide the latest closing share price by the diluted EPS we just calculated in the prior step.

It’s not easy to conclude whether a stock with a P/E of 10x is a bargain or a P/E of 50x is expensive without performing any comparisons. To give you some sense of what the average for the market is, though, many value investors would refer to 20 to 25 as the average P/E ratio range. And again, like golf, the lower the P/E ratio a company has, the better an investment the metric is saying it is.

One shortcoming of the P/E ratio is the neglect of the company’s growth potential. Therefore, the price/earnings to growth (PEG) ratio is a modified version of the price-to-earnings (P/E) ratio, where the earnings growth projections is considered. When combined with EPS, the P/E ratio helps gauge if the market price accurately reflects the company’s earnings (or earnings potential).

If the P/E is lower than the justified P/E ratio, the company is undervalued, and purchasing the stock will result in profits if the alpha is closed. The P/E ratio is just one of the many valuation measures and financial analysis tools that we use to guide us in our investment decision, and it shouldn’t be the only one. Looking at the P/E of a stock tells you very little about it if it’s not compared to the company’s historical P/E or the competitor’s P/E from the same industry.

Since it’s based on both trailing earnings and future earnings growth, PEG is often viewed as more informative than the P/E ratio. For example, a low P/E ratio could suggest a stock is undervalued and worth buying. However, including the company’s growth rate to get its PEG ratio might tell a different story. PEG ratios can be termed “trailing” if using historical growth rates or “forward” if using projected growth rates. The price-to-earnings (P/E) ratio measures a company’s share price relative to its earnings per share (EPS).

The market price of the shares issued by a company tells you how much investors are currently willing to pay for ownership of the shares. The price-to-earnings ratio (P/E) of a company is compared to its peer group, comprised of comparable companies, to arrive at the implied equity value. The relative valuation method (“comps”) estimates the fair value of a company by comparing a standardized ratio to its peer group, or competitors operating in the same industry or sector. Simply put, the P/E ratio of a company measures the amount that investors in the open markets are willing to pay for a dollar of the company’s net income as of the present date.

If Stock A is trading at $30 and Stock B at $20, Stock A is not necessarily more expensive.

The P/E ratio reflects what the market is willing to pay today for a stock based on its past or future earnings. However, the P/E ratio can mislead investors, because past earnings do not guarantee future earnings will be the same. This can be useful given that a company’s stock price, in and of itself, tells you nothing about the company’s overall valuation. Further, comparing one company’s stock price with another company’s stock price tells an investor nothing about their relative value as an investment. In addition to indicating whether a company’s stock price is overvalued or undervalued, the P/E ratio can reveal how a stock’s value compares with its industry or a benchmark like the S&P 500. Investors often base their purchases on potential earnings, not historical performance.
