Ark Invest bought 369,612 Rocket Lab shares through three exchange-traded funds and sold 16,422 Alphabet Class A shares on Tuesday. The Rocket Lab purchases came as Cantor Fitzgerald maintained an Overweight rating and a $122 price target, citing the pending Iridium Communications acquisition, 96 successful Electron launches and Neutron’s planned first launch later this year. Ark also reduced Alphabet exposure while analysts evaluated whether Google Search can retain its lead as artificial intelligence changes online information discovery. Evercore ISI analyst Mark Mahaney said Search remains Alphabet’s main financial engine, while Gemini, newer models and tensor processing units provide potential catalysts amid shifting AI competition.
