What Is the P/E Ratio?
The Price to Earnings (P/E) ratio is a fundamental stock valuation metric that shows how much investors are willing to pay per dollar of a company’s earnings. It compares a company’s stock price with its earnings per share (EPS):P/ERatio=EarningsPerShare(EPS)StockPrice
- High P/E ratio: Indicates that investors expect high growth in the future; the stock may be overvalued.
- Low P/E ratio: Suggests the stock may be undervalued or that the company is facing challenges.
This ratio is crucial for comparing companies within the same industry or evaluating market expectations over time.

Example Calculation
Suppose you want to evaluate a tech company:
- Stock Price: $200
- EPS: $8
Calculation:P/ERatio=8200=25
This means investors are willing to pay $25 for every $1 of earnings. Comparing this with industry averages helps you judge if the stock is fairly valued.
