Across its top 20 institutional holders, STM's holder base skews toward low-concentration, high-turnover investors on average (avg. concentration score 14/100, avg. turnover score 58/100).
STM ranks #920 out of 37696 tracked stocks by institutional interest — one of the most closely watched names in our coverage.
STM is a disclosed holding of Ken Griffin (Citadel Advisors LLC), one of the tracked superinvestors on AlphaSMO — it makes up 0.1% of that fund's own 13F portfolio.
STM is a top-conviction position for E20 Capital Ltd — at 12.8% of their entire disclosed 13F portfolio, it's one of their largest single bets, not just a passing allocation.
The largest dollar stake in STM belongs to Van Eck Associates CORP, but the position matters far more to E20 Capital Ltd, who has 12.8% 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.
Mather Group, LLC. has added to its STM position for two straight quarters, increasing it by $16.2K to reach $18.2K today.
Miller Global Investments, LLC has trimmed its STM position for two straight quarters, cutting it by $698.8K while still holding $270.3K.
STM is down 1.8% today, but institutions show net buying of $5.2B this quarter — a divergence between today's price move and the underlying institutional flow.
STM closed its latest fiscal year with net income of $166.0M.

STM 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.
