The P/E (price-to-earnings) ratio is one of finance's essential valuation metrics. This blog post will explain what the P/E ratio is, how it's calculated, and why it's important. We will also give you a few rules on using the P/E ratio to make better investment decisions. Let's get started.
How does the P/E ratio work?
The price-to-earnings ratio is the ratio of a company's share (stock) price to the company's earnings per share. Usually is used to find out whether companies are overvalued or undervalued.
The P/E ratio is determined by dividing the stock price of a company by its earnings per share (EPS). For example, if a company has a stock price of $100 and its EPS is $10, then its P/E ratio would be 10 ($100/$10). In a simplified way, you can say that: "P/E is the amount of years it will take to pay back the cost of buying the company based on the current profit." In the example above, this will be ten years.
The P/E ratio gives you a better understanding of how much investors are willing to pay for each dollar of earnings. A higher P/E ratio means that investors are paying more for each dollar of earnings.
For example, let's say two companies have the same EPS. Company A has a P/E ratio of 10, while Company B has a P/E ratio of 20. This means that investors are willing to pay twice as much for each dollar of earnings for Company B. The reason why similar companies may have different P/E is usually found in the expectation of future growth and your willingness to pay a higher premium now to be a part of the future income. An example of a company that has had a high P/E for a long time is Tesla Inc. which has grown rapidly, and future income is expected to be strong due to the growth.
Why is the P/E ratio important?
The P/E ratio is vital because it can give you an idea of whether a stock is undervalued or overvalued.
A low P/E ratio (below 10) may mean an undervalued stock. A high P/E ratio (above 20) may mean overvalued stock. But keep in mind that P/E ratios vary from industry to industry. That's why it's important to compare companies within the same industry when using the P/E ratio as a valuation metric.
It's also important to remember that the P/E ratio is just one metric and should not be used in isolation. Because sometimes, there is another reason behind the general rule. For example, a low P/E ratio could be because the company's business model itself is weak and does not have a promising future. It would be best to always look at a complete company analysis before making an investment decision.

How can you use the P/E ratio to make better investment decisions?
Here are a few tips on how you can use the P/E ratio to make better investment decisions:
- Compare P/E ratios within the same industry: as we mentioned earlier, it's vital to analyze P/E ratios within the same industry because P/E ratios vary from industry to industry;
- Look at other valuation metrics: the P/E ratio is just one metric, and you shouldn't rely on it exclusively. Make sure to look at other valuation metrics such as price-to-book value, price-to-sales ratio, and enterprise value-to-EBITDA ratio;
- Consider the company's growth prospects: a company with high P/E ratios may be justified if it has strong growth prospects. Conversely, a company with low P/E ratios may not be as attractive if its growth prospects are weak;
- Be aware that companies can manipulate P/E ratios through accounting techniques such as share buybacks. That's why make sure to do your own research before making any investment decisions.
That's it for this introduction to the P/E ratio. In future articles, we will explore other aspects of this valuable metric and look at how you can use it to make better investment decisions.
But for now, remember these key points: The P/E ratio is a measure of how much investors are willing to pay for each dollar of earnings a company generates. It can be used to compare different companies or industries. And finally, it's essential to watch the trend in the P/E ratio over time – especially when making long-term investments.
