Notable Holders

BFLY ranks #2497 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

BFLY is a top-conviction position for Fosun International Ltd — at 19.3% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

Smart Money Convergence

BFLY does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
