Smart-money-signal read: LRCX Q1 2026 holder flows are strongly net-bullish among semiconductor-conviction active managers. Fidelity +$2.6B (+97.1%), JPMorgan +$2.5B (+69.8%), Invesco +$1.3B, Franklin +$789M, Geode +$1.7B, UBS AM +$689M, Amundi +$764M, Legal & General +$502M, Nuveen +$573M are all meaningful increases in semiconductor exposure. Sellers: BlackRock -$5.4B, State Street -$2.4B, Capital World -$3.1B, Morgan Stanley -$649M, Goldman Sachs -$376M, Northern Trust -$560M, Bank of America -$351M, Ameriprise -$461M. The split between Fidelity/JPMorgan/Invesco adding and BlackRock/State Street reducing suggests a rotation within active management rather than a uniform view. The net read: bullish on semiconductor equipment (LRCX specifically) -- the buyer cohort is larger and more aggressive in absolute terms than the seller cohort.
