AI Holders Summary · Q1 2026

A falling stock price runs through nearly every line of MicroStrategy's (MSTR) Q2 2026 institutional data — across $64.2 million held by 77 institutions, most top holders' position values fell even where share counts rose, the signature of a price decline outrunning real buying. Lauer Wealth is the clear exception and the quarter's standout mover: its share count jumped from 4,046 to 38,896, an 861% increase representing a genuine $3.4 million addition — so aggressive that it's the only top holder whose position value still ended up net positive despite the broader price weakness. Strong Tower Advisory Services remains the largest holder at $12.4 million (19.3% of total institutional value) after adding 5.5% more shares ($649,193 in flow), and Swedbank AB added 10.1% ($719,606). On the other side, Patriot Investment Management Group cut its stake nearly in half (-49.9%, -$629,548), the largest real sale this quarter, with Pacific Capital Wealth Advisors and Beaird Harris Wealth Management also trimming meaningfully.

A price decline hiding in plain sight

Look across the top holder list and a pattern repeats: Strong Tower Advisory Services added 5.5% more shares (a real $649,193 addition) yet its position's dollar value fell $4.5 million — the largest value decline of any holder. Swedbank AB added 10.1% in shares ($719,606 in flow) while its value dropped $2.4 million. Independent Financial Group grew its stake 5.1% ($370,237) even as its value fell $2.8 million. In each case, real buying wasn't enough to offset a falling share price — a clear signal that MSTR's stock declined meaningfully over the quarter regardless of what individual holders were doing.
