What the price implies

A reverse DCF: instead of guessing a fair value, it asks what growth today's price already assumes. How it works.

Applied Opt's free cash flow was negative in fiscal 2025, so a cash-flow reverse DCF doesn't give a meaningful answer. The Modeling tab works from revenue and margins instead.

Fundamental grade
