I've been investing for 35 years, AI has changed everything.

The rapid rise of artificial intelligence necessitates a strategic shift in investment portfolios, particularly regarding the heavy concentration of the S&P 500. Currently, 40% of the index is comprised of just ten companies, all betting heavily on AI and financing growth through significant debt. To mitigate the risks of a potential AI bubble, investors should diversify into global markets, small and mid-cap stocks, and alternative assets like gold. Gold’s recent reclassification as a Basel III Tier 1 asset makes it an increasingly vital hedge against economic instability. Furthermore, maintaining substantial cash reserves—a strategy currently employed by Warren Buffett—provides the liquidity needed to navigate market downturns and capitalize on future opportunities. Relying solely on the US market ignores the historical reality that economic dominance is cyclical and shifts over time.
