Across its top 20 institutional holders, POST's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 6/100, avg. turnover score 42/100).
POST ranks #1470 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
POST is a top-conviction position for H Squared Management LP — at 12.2% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in POST belongs to BlackRock, Inc., but the position matters far more to H Squared Management LP, who has 12.2% 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.
True Wealth Design, LLC has added to its POST position for two straight quarters, increasing it by $11.1K to reach $14.3K today.
Cohen Capital Management, Inc. has trimmed its POST position for two straight quarters, cutting it by $2.5M while still holding $5.6M.

Top 5 Institutional Movers
POST 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.
