These per-flag figures are observational — a flag firing is not a randomized assignment, so any edge can reflect what kind of names trip a flag, not the flag itself. Descriptive, not causal.
Scope: these are forward returns vs the S&P among names still covered at each horizon's end, within the curated universe — not a survivorship-clean whole-market backtest. Names later dropped from coverage are counted as attrition (not hidden), and single-session moves beyond ±300% are treated as split/data artifacts and excluded.

AI take — daily, AI-generated
AI leans mixed
Strong growth and exceptional PEG ratio are offset by patent litigation, inventory headwinds, and tariff risks that threaten near-term margins; the valuation looks cheap but execution risk is real.
