Price–earnings ratio

The price-earnings ratio, or P/E ratio for short, is a fancy way of comparing how much a company is worth (its value) to how well it is doing financially (its earnings).

Think of it like buying a toy at the store. You want to make sure the toy is worth the money you are paying for it. The P/E ratio helps investors figure out if a stock is worth the price they are paying for it.

To calculate the P/E ratio, you take the price of one share of the company's stock (how much people are willing to pay for it) and divide it by the company's earnings per share (how much money the company is making per share).

For example, if a company's stock price is $50 and its earnings per share are $2, the P/E ratio is 25. This means investors are willing to pay $25 for each $1 of the company's earnings.

A high P/E ratio can mean investors have high expectations for a company's future earnings, while a low P/E ratio can mean investors think the company isn't doing well financially.

But like with all things in investing, the P/E ratio isn't the only thing to consider when making a decision about a stock. You also need to look at other factors, like the company's overall financial health, its industry and competition, and any potential risks.
