PEG Ratio PEG
The P/E ratio divided by the earnings growth rate, to judge value against growth.
What it is
The PEG ratio adjusts the P/E ratio for how fast a company's earnings are expected to grow. It tries to answer whether a high P/E is justified by high growth. A PEG of roughly 1 is often treated as a rule-of-thumb fair value.
Why it matters
PEG helps compare fast growers against slow growers that a raw P/E would make look misleadingly cheap or expensive. Pitfalls: it is very sensitive to the growth-rate input, breaks down for companies with no growth or negative earnings, and the '1 = fair' rule is a heuristic, not a law.
How it's calculated
Divide the P/E ratio by the expected annual earnings-growth rate expressed as a whole number (for example, divide by 15 for 15% growth).
