What is PEG ratio?

The PEG ratio adjusts the P/E for growth. Peter Lynch popularised the idea that a fairly priced company's P/E roughly equals its growth rate, so a PEG of 1. A stock on 30× earnings growing at 40% a year (PEG 0.75) can be cheaper than one on 15× growing at 5% (PEG 3). Investors who buy low-PEG stocks are said to follow a GARP (growth at a reasonable price) style.

Formula

PEG = P/E ÷ annual EPS growth rate (%) Flash Finance uses the 3-year compounded profit growth as the growth rate

How to read it

  • PEG below 1 suggests growth is not fully priced in, if the growth continues.
  • The whole ratio rests on the growth estimate. Past growth is only a proxy for future growth.

Common mistakes

  • Using PEG with growth that came from a depressed base year, which makes the growth rate (and the PEG) misleading.
