Across its top 20 institutional holders, MRVI's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 16/100, avg. turnover score 42/100).
MRVI ranks #3255 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
MRVI is a disclosed holding of Israel Englander (Millennium Management), one of the tracked superinvestors on AlphaSMO — it makes up 0.0% of that fund's own 13F portfolio.
MRVI is a top-conviction position for 12 West Capital Management LP — at 8.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in MRVI belongs to Gtcr LLC, but the position matters far more to 12 West Capital Management LP, who has 8.2% 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.
Braidwell LP has added to its MRVI position for two straight quarters, increasing it by $27.2M to reach $54.3M today.
Alliancebernstein L.p. has trimmed its MRVI position for two straight quarters, cutting it by $157.1K while still holding $397.3K.
MRVI is down 1.1% today, but institutions show net buying of $181.9M this quarter — a divergence between today's price move and the underlying institutional flow.
MRVI reported a net loss of $77.4M over the trailing twelve months.

MRVI 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.
