Smart money is quietly loading 5 stocks
Comparing 13F-HR filings for period-of-report 2026-03-31 vs 2025-12-31 across the five-fund watchlist (Berkshire, Bridgewater, Renaissance, Citadel, Two Sigma), 1,467 manager-tickers showed Q/Q acceleration. After excluding mega-caps, sub-$1B caps, ADR-only foreign listings, single-fund-dominated block buys (>80% from one non-Berkshire filer), positions inside the 7-trading-day earnings blackout, and tickers with elevated retail attention, five US-listed names cleared all rails. The single most surprising finding: PACCAR (PCAR) is a new Bridgewater position of ~777K shares, with Bridgewater, Renaissance, Citadel and Two Sigma all adding into the same name — coincident accumulation by a macro hedge AND three quant shops in a sleepy heavy-truck OEM is unusual, and the obvious read-through is positioning for the 2027 EPA NOx pre-buy cycle that the sell-side has not yet fully reflected. Berkshire was largely a story of trims this quarter (Chevron -35%, Nucor -39%, Bank of America small, exits of Charter/Mastercard/Visa/UNH/Allegion/AON), with the only large incremental adds being Alphabet, Lennar, Delta, NYT and a small Macy's restart — none of which qualified here on the cross-fund / low-retail filters.
PCAR
PACCAR IncFour of the five watchlist managers added in Q1, two of them new — including Bridgewater opening a ~777K-share position. The macro signal lines up with a hard catalyst: model-year 2027 heavy-duty trucks must meet the EPA's 0.035 g/hp-hr NOx standard, and fleets have begun pre-buying compliant Class 8 units ahead of the cost step-up (industry estimates put the per-tractor delta at $20-30K). PACCAR's December order book already showed Class 8 bookings up 21% Y/Y, and management has guided to two new proprietary engine platforms. The pre-buy typically front-loads the cycle into the back half of the year before the regulation takes effect — a setup the sell-side has been slow to model because Q4 2025 truck demand was weak.
