Across its top 20 institutional holders, NAMS's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 22/100, avg. turnover score 46/100).
NAMS ranks #3026 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
NAMS is a top-conviction position for Medicxi Ventures Management — at 42.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in NAMS belongs to Frazier Life Sciences Management, L.P., but the position matters far more to Medicxi Ventures Management, who has 42.2% of their own portfolio riding on it — a reminder that the biggest holder by size and the holder with the biggest bet aren't always the same fund.

Wellington Management Group LLP has trimmed its NAMS position for two straight quarters, cutting it by $169.2M while still holding $7.4M.

NAMS 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.
