Price-to-Earnings Ratio

The Price-to-Earnings Ratio (P/E Ratio) is a financial metric used to determine the valuation of a company. It’s calculated by dividing the market value per share (price of the stock) by the earnings per share (EPS).

The formula for P/E Ratio is:

P/E Ratio = Market Value per Share / Earnings per Share

This ratio tells you how much investors are willing to pay per dollar of earnings. A high P/E ratio could mean that a stock’s price is high relative to earnings and possibly overvalued. Conversely, a low P/E might indicate that the current stock price is low relative to earnings and possibly undervalued.

For example, if a company’s stock is trading at $20 per share and the earnings per share over the last 12 months were $1, then the P/E ratio would be 20.

P/E Ratio = $20 / $1 = 20

The P/E ratio is commonly used by investors and analysts to determine the relative value of a company’s shares in an apples-to-apples comparison. It can also compare a company against its own historical record or to compare aggregate markets against one another or over time. However, the P/E ratio isn’t a measure of the inherent value of an asset and it doesn’t consider factors like growth rates or dividends, so it’s important to use it alongside other metrics.
