Notable Holders

PRIM ranks #1322 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

PRIM is a top-conviction position for Value Holdings Management Co. LLC — at 6.6% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.

The largest dollar stake in PRIM belongs to BlackRock, Inc., but the position matters far more to Value Holdings Management Co. LLC, who has 6.6% 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.

A. D. Beadell Investment Counsel, Inc. has trimmed its PRIM position for two straight quarters, cutting it by $3.7M while still holding $3.8M.

PRIM is up 1.1% today, and institutions have been net buyers of $1.4B this quarter — today's price move and the underlying institutional flow are pointing the same direction.

Smart Money Convergence

PRIM 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.
