Alas, Free Cash Flow I Knew You Well

The article argues that investors should balance enthusiasm for AI-driven capital spending with exposure to companies generating free cash flow and shareholder distributions today.

• Higher real interest rates, inflation and geopolitical risks may make cash-generating companies more resilient, while utilities and real estate remain sensitive to rates.
• The analysis covers the Russell 1000 from August 31, 2006 to August 31, 2026, with quarterly rebalancing, quintile portfolios, three-standard-deviation winsorization and return spreads between the highest and lowest factor quintiles.
• Free cash flow margin generally outperformed capital intensity over the testing period, although it underperformed during the last two to three years as investors favored the AI capital-spending cycle.
• Information technology capital intensity is expected to decline from 21.8% in 2024 to 11.8% in 2028, while hyperscalers' cumulative capital spending could exceed $6 trillion between 2024 and 2030.
• The main risk is that capital expenditure outpaces earnings and cash-flow growth, producing lower free cash flow, higher leverage, shareholder dilution and underused assets; Bloomberg's optimistic scenario nevertheless estimates AI spending could contribute up to 17% of cumulative U.S. GDP growth by 2030.

Takeaway: Investors may diversify future-growth exposure with core equity strategies emphasizing capital discipline, free-cash-flow generation and dividends, while recognizing that the AI investment cycle could represent a new regime in which capital intensity is rewarded.
