PEG — Price/Earnings-to-Growth Ratio

DeepScreen explains PEG as follows: PEG relates a company's earnings multiple to its growth rate. A reading near 1 is often considered balanced, but growth quality and durability matter more than a single threshold.

Formula

P/E ratio ÷ earnings growth rate

Illustrative example

A P/E of 20 and annual earnings growth of 10% give a PEG of 2. Enter growth as 10, not 0.10. This calculation assumes positive, meaningful earnings and growth.

Educational example; these are not reported company figures.

How to interpret it

  • Below 1 can mean growth is inexpensive relative to the P/E.
  • Above 2 can mean investors already price in strong growth.

Limitations

  • Forecast growth can be wrong.
  • Negative or unusually volatile growth makes PEG unreliable.
