According to @StockMKTNewz, Leon Cooperman updated details of his $3.2B portfolio with positions as of September 30, 2025 (Q3) (source: @StockMKTNewz on X, Nov 14, 2025). In the U.S., institutional managers disclose quarter-end long equity holdings on SEC Form 13F within 45 days of quarter end, putting Q3 disclosures in the October to mid-November window (source: U.S. SEC, Form 13F instructions). Traders track these filings to gauge sentiment and positioning changes that inform entries and exits in affected tickers around the next trading session (source: CFA Institute, guidance on using Form 13F filings). Because equity risk appetite and crypto assets have exhibited higher correlation since 2020, updates that shift sentiment in U.S. equities can influence BTC and ETH monitoring and hedging among cross-asset traders (source: International Monetary Fund research on crypto–equity correlation). Actionable next steps include pulling the full filing from EDGAR, screening for the largest notional changes, and watching premarket volume and spreads in those names and related sector ETFs once parsed (source: U.S. SEC EDGAR).
