In this article, we will discuss the importance of using the price-to-earnings ratio in stock valuation. We will explain how to calculate the price-to-earnings ratio and how to use it to compare companies and measure stock performance across different sectors. We will also discuss the limitations of the price-to-earnings ratio and how it can be used correctly to evaluate investments.
About the Price-to-Earnings Ratio
The price-to-earnings ratio is a measure of a company’s share price compared to its earnings. The price-to-earnings ratio is used to make a decision about investing in a particular stock and can help explore future trends for the stock. The price-to-earnings ratio can also indicate whether a price is high or low compared to other companies in the same sector.
How Does the Price-to-Earnings Ratio Work?
Before you can use the price-to-earnings ratio, you need to understand what it is. It is easy to calculate as long as you know the company’s share price and its earnings per share. The formula looks like this: Price-to-Earnings Ratio = Share Price ÷ Earnings per Share.
Price-to-Earnings Ratio by Sector
Each sector has a certain range of price-to-earnings ratios that is considered normal for that sector. For example, at the beginning of 2021, Fidelity research indicated that the average price-to-earnings ratio in the healthcare sector is around 70. In contrast, in the banking sector, companies have a price-to-earnings ratio of about 11.5.
How to Compare Companies Using the Price-to-Earnings Ratio
Using the price-to-earnings ratio, you can not only identify which sectors are overpriced and which are underpriced, but you can also compare companies’ prices within the same sector. For example, if two companies have a share price of $50, one may be much more expensive than the other, depending on the earnings and growth rate per share.
Limitations of the Price-to-Earnings Ratio
Remember that there is no single ratio or rule that you can apply to achieve investment success. You should consider what is happening in the world, the markets, and the economy. For example, if economies are in trouble or if there is a global health crisis, company earnings may be worse than expected, and stock prices can often change. It is possible for investment to start declining and appear to be valued at 14, but if you jump into the situation quickly without considering the overall market, the price-to-earnings ratio may decrease even more.
Conclusion
If you are fond of buying a stock because it has a good price-to-earnings ratio, make sure you research and find out if it is truly as good as it seems. Ask yourself these questions: Is the company’s management honest? Is the company losing its key customers? Is the share price or performance a result of forces in the entire sector, industry, or economy? Or is it due to bad news related to the company itself? Is the company heading toward a downturn? The basic price-to-earnings ratio is a great indicator when used in the right context, but it is not useful on its own at least until you become well acquainted with your investments and opportunities.
