Smart money is quietly loading 5 stocks
This scan compared the two most recent 13F windows filed by the five funds on the watchlist — reportDates 2026-03-31 (latest, filed by mid-May) versus 2025-12-31 (prior). Roughly 895 US-listed CUSIPs cleared the raw acceleration filter (more funds adding than trimming; aggregate share count up ≥25% Q/Q or ≥2 new positions; single-fund block-dominance exempted only for Berkshire). Five names survived the quality rails, the retail-attention filter, and the seven-trading-day earnings blackout. The single most surprising finding of the run is one we explicitly excluded from the stock list: Berkshire's brand-new 39.8M-share ($2.65B) Delta Air Lines position — the first airline stake since Buffett publicly repudiated the industry in 2020. It cleared the acceleration test, but retail attention on DAL exploded after the May 15 filing (DAL now +34% YTD, wall-to-wall press coverage), so it fails the "retail hasn't caught on" gate. We reference it here for context and skip it in the picks. Also worth noting: Berkshire fully exited UnitedHealth, Amazon, Visa, Mastercard, Domino's, Pool, Charter, Heico, Lamar and Aon in the same quarter, and trimmed Constellation Brands by ~95% — Greg Abel's first quarter as CEO looks like a portfolio simplification.
LEN
Lennar CorporationBerkshire added 3M shares (+43%) to a Lennar position it first opened in Q4 2024, taking the stake past $875M — the largest single-quarter addition to LEN in Berkshire's history. Two Sigma nearly doubled alongside. The setup is a rate-cut cycle trade: Lennar trades near book value, sits on record cash post-Millrose spin, and is the lowest-cost land-light builder in a market where existing-home supply is still tight. Buffett/Abel rarely chase homebuilders — the 43% top-up implies they see the current 8x forward P/E as protection against the cycle risk. Catalyst retail hasn't priced: land-light model means margin resilience if rates fall AND if rates stay high — an asymmetric setup the sell side still models as pure cyclical.
