BlackRock has trimmed its most direct AI stock exposure as part of a strategic rebalancing approach, according to Chief Investment Officer of Global Fixed Income Rick Rieder. Speaking on CNBC, Rieder described the sales as rebalancing rather than a reversal of the firm's AI investment theme. The $13.9 trillion asset manager reported record assets under management as of March 31, making its positioning particularly significant for market observers.
Rieder explained that his team specifically trimmed positions in companies whose earnings depend most heavily on the AI buildout. As reported by CNBC, he framed the shift as trimming winners rather than exiting the theme entirely. The firm also cut a notable slice of its overall equity exposure as part of this strategic rebalancing process. This approach reflects BlackRock's selective stance on AI investments throughout the year.
The move extends Rieder's cautious stance on AI valuations, which he has maintained throughout the year. At a CNBC event in June, he rejected dot-com comparisons, noting that the Magnificent 7 traded near 26 times earnings with forward earnings growth above 20%. His January outlook similarly argued that 2026 would reward income and selectivity as AI gains separate winners from laggards. Wall Street remains divided on AI investments, with JPMorgan urging clients to buy chip dips while Morgan Stanley prefers hyperscalers.
Rieder indicated that BlackRock may redeploy into cheaper beneficiaries of AI adoption, potentially targeting power producers, industrials, and infrastructure builders that could capture the next wave of data center spending. Signs of profit-taking are spreading across the AI supply chain, with AI memory stocks leading 2026 trading despite cautious money flows. The firm now recommends a 1% to 2% Bitcoin allocation as another route to returns beyond dominant AI names.
The concentration remains a deeper worry for market observers, as the S&P 500 has repeatedly set records on weak market breadth with a small group of mega caps carrying the index. BlackRock's wider portfolio guidance this year points to the same trend, with the firm recommending diversification beyond dominant AI names. The coming earnings season may reveal whether the market's biggest AI names can still defend their premiums amid growing investor caution.
