Price/Earnings-to-Growth (PEG) Ratio Formula

PEG Ratio = P/E Ratio / Annual EPS Growth Rate

Adjusts Price-to-Earnings valuation metrics by factoring in the company's expected annual earnings growth rate.

Worked Example: Stock with P/E ratio of 30, growing earnings at 15% p.a.

PEG Ratio: **2.00**. (A PEG ratio above 2.0 indicates premium growth valuation).

PEG Ratio: Valuation adjusted for company earnings growth

Pooja compared two stocks with a P/E ratio of 30. Stock A's earnings were growing at 15% p.a. (PEG 2.0), while Stock B's earnings were growing at 30% p.a. (PEG 1.0).

Even though both had the same P/E ratio, Stock B was a much more attractive buy because its growth adjusted PEG was 1.0 compared to Stock A's PEG of 2.0.

The PEG ratio adjusts Price-to-Earnings metrics by dividing them by the company's expected annual earnings growth rate.

A PEG ratio under 1.0 indicates a stock is undervalued relative to its growth, while a ratio above 2.0 suggests growth is premium priced.

Frequently Asked Questions

What is the PEG Ratio?

The Price/Earnings-to-Growth (PEG) ratio is a valuation metric that determines the relative trade-off between the price of a stock, the earnings generated per share, and the company's expected growth.

What does a PEG ratio below 1.0 indicate?

A PEG ratio below 1.0 generally suggests that a stock is undervalued given its expected earnings growth, making it an attractive prospect for GARP (Growth at a Reasonable Price) investors.

Why use PEG instead of just P/E?

P/E ratios can make fast-growing tech companies look extremely expensive. The PEG ratio factors in that growth rate, providing a more balanced view of valuation.
