How to read this chart

A low PEG vs the stock's own history suggests the market may not be fully pricing in the growth rate — the combination of P/E and growth looks unusually attractive.

Key caveats

  • Forward PEG is based on analyst estimates that are frequently optimistic — treat it as a sanity check, not a primary signal.
