P/E Ratio: Understanding Stock Valuation

What is the P/E Ratio?

The Price-to-Earnings (P/E) Ratio is a popular valuation metric used by investors to compare a company's current share price to its per-share earnings. It helps determine if a stock is overvalued, undervalued, or fairly valued.

How is it Calculated?

The P/E Ratio is calculated by dividing the current market price per share by the earnings per share (EPS) over a 12-month period (usually the last four quarters).

Formula:

P/E Ratio = Market Price Per Share / Earnings Per Share (EPS)

What Does it Mean?

• High P/E Ratio: May indicate that investors expect higher earnings growth in the future, or that the stock is overvalued.
• Low P/E Ratio: May suggest that the company is undervalued, or that investors expect slower growth.
• Comparison: The P/E ratio is most useful when comparing a company to its historical P/E, its competitors, or the industry average.

Practical Example

Imagine Company A's stock trades at $50 per share, and its earnings per share (EPS) over the last year were $5.00.

P/E Ratio = $50 / $5.00 = 10

This means investors are willing to pay $10 for every $1 of Company A's earnings.
