"Big Short" Investor Steve Eisman Just Issued a 4-Word Warning to Investors. You Might Not Be as Diversified as You Think.

Steve Eisman warns that investors may be overexposed to AI through a single concentrated trade, even those believing they are diversified. He sold his Alphabet stake to reduce AI exposure and notes that both stock and bond markets are heavily tied to AI infrastructure spending. The S&P 500 has 38% in tech stocks, with megacap AI companies dominating index funds. Eisman suggests diversifying through equal-weight index funds, small-cap stocks, and government bonds rather than corporate bonds.
