Stanley Druckenmiller Sells Broadcom Stock, Buys Sandisk, a 1,000% AI Stock Up Since Early 2025

Billionaire Stanley Druckenmiller sold Broadcom stock and bought Sandisk, a flash memory maker, in the third quarter. Sandisk has added 1,050% since its spin-off from Western Digital in February 2025. Broadcom has a dominant position in semiconductor markets, including AI infrastructure, with a 75% market share in AI ASICs. The company's AI revenue rose 65% to $20 billion in 2025, and is expected to triple by 2027. Wall Street estimates Broadcom's adjusted earnings will grow at 43% annually through 2027, making the current valuation reasonable.
