Cathie Wood Buys AI Chip Stock Amid Surge

Cathie Wood, the head of Ark Investment Management, is actively investing in momentum-driven tech stocks, recently acquiring $6.5 million of Cerebras stock as the AI chip company's share price climbed. Wood's investment strategy centers on high-growth sectors like artificial intelligence, blockchain, and robotics, which she believes hold significant future potential.

Despite Wood's focus on innovation, the Ark Innovation ETF has exhibited considerable volatility. While the ETF delivered strong returns in 2020, it experienced substantial losses in 2022. As of September 8, 2026, its five-year annualized return was -6.45%, contrasting with the S&P 500's 11.20% over the same period. This performance has led to significant investor withdrawals, with approximately $1.74 billion in net outflows over the past 12 months.

Wood maintains a bullish stance on AI, viewing it as a critical driver of productivity, economic expansion, and enhanced corporate profits. She contrasts the current AI buildout with historical infrastructure projects, noting that AI revenues appear robust. Wood suggests that companies effectively leveraging AI will distinguish themselves, securing stronger margins and competitive advantages in the evolving market.
