Price-to-Earnings Ratio
The Price-to-Earnings (P/E) Ratio is one of the most widely used metrics for valuing a company. It measures a company's current share price relative to its earnings per share (EPS).
There are two main types of P/E ratios:
- Trailing P/E: Based on actual earnings from the past 12 months
- Forward P/E: Based on projected future earnings
A high P/E ratio could mean that a stock is overvalued, or that investors expect high growth rates in the future. Conversely, a low P/E might indicate an undervalued stock or that the company is facing challenges.
It's important to compare P/E ratios among companies within the same industry, as different sectors have different average P/E levels.
P/E Ratio = Market Price Per Share / Earnings Per Share (EPS)
Example
If a company's stock trades at $100 and its EPS is $5, the P/E ratio is 20 ($100 / $5). This means investors are willing to pay $20 for every $1 of earnings.
