A research filter, not a predictor — not financial advice. Grades rank growth stocks on evidence-based quality signals from end-of-day data; they are not buy/sell calls or price forecasts. Always do your own research.

Butterfly Network, Inc. BFLY

Mixed (early) broader-coverage candidate · Butterfly Network, Inc.

On FrontierLab's discovery record since 2026-06-18 (15 weeks ago) — when this name first surfaced. (distinct from the snapshot date below)

Auto-graded broader coverage — sourced by an automated screen and graded on default bands, not the sector-calibrated bands the curated screener uses. A "Mixed (early)" here is NOT the same bar as a curated grade; these are auto-screened candidates for your own research, shown as of their surface date (2026-09-23), not the curated Frontier signal.

⚡ Surfaced on a price move — momentum is where to look, not a buy signal. The move that surfaced this name does not make it a good entry.

⚠ Pump risk: parabolic/spike characteristics detected in the screen flags. Treat any positive grade with extra skepticism.
