Smart money is quietly loading 5 stocks

Compared the June 30 2026 13F-HR filings (filed mid-August) against March 31 2026 filings (filed mid-May) across the five configured funds: Berkshire Hathaway, Bridgewater Associates, Renaissance Technologies, Citadel Advisors, and Two Sigma Investments. 787 stocks met the raw acceleration filter (net buyers > sellers AND either ≥25% Q/Q aggregate share increase or ≥2 new positions, puts excluded). After stripping mega-cap retail favorites, sector ETFs, meme-tracked names, imminent-earnings reporters, and single-fund block buys from non-Berkshire filers, five names surfaced cleanly. Notable concentration in defensives (two regulated utilities) and in Gartner — a mid-cap research advisory that was crushed in 2025 on AI-disruption fears. The most surprising finding: Bridgewater newly initiated positions in three of the five picks (ATO, NI, IT). Dalio's team deliberately runs low turnover, so new initiations are a thesis-level signal and not a tactical trade. Four of the five picks are currently trading at or below the funds' Q2 average cost basis, meaning retail has not yet followed the accumulation.
