Global Markets Decline Amid Tech Selloff and Rising AI Investment Costs

Global markets experienced a tech-led selloff amid concerns over high valuations and rising AI-related capital expenditures. US indices showed mixed performance, with the Dow gaining modestly while the Nasdaq and S&P 500 declined. Asian stocks, led by South Korea's Kospi, fell sharply. Investors rotated from growth and tech stocks into value, defensive sectors, and precious metals, as gold and silver prices surged to record highs. Alphabet's increased AI spending and disappointing forecasts from chipmakers like Advanced Micro Devices intensified market caution, while cryptocurrencies also declined.
