Mega-Cap Tech Loses Valuation Premium Amid AI Spending Pressure
Goldman Sachs Research has reported that top mega-cap stocks are losing their valuation premium over the broader market. The forward price-to-earnings multiples of the largest companies have fallen sharply and are now converging toward the valuation of the other 495 stocks in the S&P 500.
The shift is due to two major pressures: a higher cost of capital and dramatically greater capital intensity. Companies like Microsoft MSFT, Amazon AMZN, Meta Platforms META, and Alphabet GOOGL are committing enormous sums to artificial-intelligence infrastructure, including data centers, chips, and power capacity.
These investments may support substantial future growth but consume cash today. Higher borrowing costs reduce the present value investors assign to future earnings and cash flows, resulting in a significant valuation de-rating among Wall Street's largest companies.
