Smart money is quietly loading 5 stocks
We compared the Q1 2026 13F-HR filings (period 2026-03-31, filed mid-May) against Q4 2025 filings (period 2025-12-31) for the five funds on our watchlist: Berkshire Hathaway, Bridgewater Associates, Renaissance Technologies, Citadel Advisors, and Two Sigma Investments. Of roughly 17,000 unique CUSIPs that appeared across the latest filings, 893 met our cross-fund acceleration definition, and five names cleared both the magnitude filter and the retail-attention rails after we excluded puts, mega-cap retail favorites, and earnings within seven trading days. The single most surprising finding: Berkshire opened an entirely new $2.6B position in Delta Air Lines while simultaneously gutting Chevron (-35%) and Constellation Brands (-95%) — Buffett/Abel are quietly reweighting from energy and consumer-staples back into a cyclical airline they exited in 2020. The other Berkshire signals (NYT +199%, Lennar +43%) reinforce a domestic-services and housing-pivot read, while PACCAR and Pan American Silver are pure cross-fund cluster trades with no Berkshire participation but four-of-four buyer agreement.
DAL
Delta Air Lines, Inc.Berkshire's first-ever Delta position is the largest single new airline-equity disclosure they've made since exiting all four legacy carriers in April 2020. The $2.6B Q1 stake — roughly 6% of DAL's float — landed alongside the simultaneous halving of Chevron, suggesting the team is rotating from a saturated energy bet into a domestic-services name where premium-cabin and loyalty revenue (now ~57% of operating profit) decouple results from fuel and macro freight. Citadel adding 14% on top is corroborating, not coincidental. The unpriced catalyst: AmEx co-brand renewal economics step up materially in 2026 and DAL's Q2 print on July 10 is the first chance to see the contribution.
