PEG Ratio Formula & Definition

PEG Ratio = P/E Ratio / 5-Year Diluted EPS CAGR (%)

The PEG ratio divides the price-to-earnings ratio by the company's five-year compound annual growth rate of diluted EPS, expressed in percent. A P/E of 20 and a five-year diluted EPS CAGR of 10% give a PEG of 2.0. The growth is reported, historical earnings growth from annual statements, not an analyst forecast. A PEG near 1 is often read as fairly priced for its growth; lower can mean cheaper relative to growth. The ratio is N/A when the P/E is unavailable or not positive, or when the five-year diluted EPS CAGR is unavailable or not positive. Each day of the history uses the CAGR that was known on that day.
