8 institutional buyers accumulated $6.6M in new SMCI positions during Q3 2026, while 1 seller trimmed $37.3M. The cluster is overwhelmingly bullish in count but the single large seller (Assenagon) dominates the dollar flow. This buying likely reflects anticipation of the massive Q1 FY2027 revenue pre-announcement ($18.5B-$19.5B vs prior guidance of $14.5B-$15.5B) filed one day after quarter-end, but the 45-day reporting lag means positions may have already been adjusted.
