PEG Ratio Analysis

PEG ratio = P/E ÷ Growth Rate. A PEG below 1.0 is often considered undervalued relative to growth. Above 2.0 may indicate overvaluation.

What is the P/E Ratio?

The price-to-earnings (P/E) ratio is the most widely used stock valuation metric. It tells you how much investors are paying for each dollar of earnings.

P/E = Stock Price ÷ Earnings Per Share (EPS)
A P/E of 20 means investors are paying $20 for every $1 of annual earnings.

High P/E: Investors expect strong future growth (or the stock is expensive).
Low P/E: The market has low growth expectations (or the stock is a bargain).

The P/E ratio should never be used in isolation. Compare it to the sector average, historical average, and factor in growth rates (PEG ratio) for a complete picture.
