The first quarter of 2026 represents a sharp structural shift in institutional asset management. The definitive transition of power at Berkshire Hathaway into the "Abel Era" has brought a highly concentrated, deliberate approach to capital reallocation, signaling a broader market trend: the wholesale clearing out of mid-conviction legacy positions in favor of high-conviction structural bets.
Simultaneously, the consensus on Artificial Intelligence has fractured into a distinct multi-layer playbook. Institutional capital is aggressively separating the Hardware and Foundry Layer (which is receiving massive inflows) from the SaaS/Application Layer (which is facing systematic liquidation). Managers are no longer buying "Tech" as a single factor; they are executing highly specific pair-trades to exploit growing valuation dislocations.
