MPLT is a top-conviction position for Nan Fung Group Holdings Ltd — at 26.5% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in MPLT belongs to Novo Holdings A/S, but the position matters far more to Nan Fung Group Holdings Ltd, who has 26.5% 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.

MPLT 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 2026-09-30 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.
