Frequently asked questions
What is a good P/E?
There is no universal number — P/E is only meaningful against a company's peers, its own history and its growth. A high P/E can reflect fast growth; a low one can reflect real problems.
What is PEG?
PEG divides the P/E by the expected earnings-growth percentage. A PEG near 1 is often described as fairly valued relative to growth, but growth is only an estimate.
Trailing or forward EPS?
Trailing uses the past 12 months (known facts); forward uses forecast earnings (an estimate). Use the same basis consistently when comparing.
