In his latest notes, Ray Dalio addresses a critical question for investors amid the AI-driven stock market surge: how should one allocate assets during a transformative technological revolution? Dalio emphasizes that technological advancement does not automatically make related stocks attractive. Historical tech cycles—marked by excitement, crowding, volatility, and eventual shakeouts—show that even long-term winners like Microsoft and Apple experienced severe drawdowns. Today's AI sector faces similar uncertainties: overinvestment, intensifying competition, geopolitical tensions (e.g., Taiwan's chip supply), tax policy shifts, anti-AI sentiment, and potential disruption from future technologies like quantum computing. Dalio's core argument focuses on the highly concentrated market structure, where a few tech giants dominate major indices. He warns investors against unknowingly holding concentrated, correlated exposures. Instead of chasing a handful of AI leaders, he advocates for a robust, diversified portfolio of 15 or more high-quality, uncorrelated investments, risk-balanced to match an investor's volatility tolerance. Mathematically, such diversification significantly improves the risk-return ratio—for example, holding 15 uncorrelated assets can boost the ratio by over four times compared to a single concentrated bet. Dalio cautions that future equity returns appear low, with his bubble indicator suggesting real returns could be negative over the next 5-10 years. He stresses that knowing what you don't know is as important as knowing what you do. In an environment of high uncertainty and concentration, avoiding large, concentrated bets on AI stocks is prudent. The optimal strategy is disciplined diversification—the "holy grail" of investing—to navigate this technologically driven cycle with lower risk and comparable or better returns.
