Ark Invest

ARK Invest purchased $81 million in Nvidia shares while selling $110 million of AMD stock. Cathie Wood's firm locks in profits after AMD's massive surge.

The well-known investment manager, who built her name on bets on Tesla and futuristic technologies, is increasing her holdings in Nvidia at the expense of its major competitor. The purchase came immediately after impressive reports and a 70% growth forecast — and at a surprising price.
