Larry Fink
World's largest asset manager. Q4 2025 13F-HR discloses $5.92T across 4,513 unique issuers - every BLK-managed product with US-equity discretion (iShares ETFs, index mutual funds, active funds, SMAs). Top holdings closely mirror S&P 500 weights because passive index AUM dominates the book; this is not a stock-pick portfolio. Top 12 named single tickers sum to 33.5%; iShares Trust cross-holdings add another 2.6% ($156B across many self-held ETF classes); the remaining ~63.9% is the long tail of 4,500+ issuers.
BlackRock, run by founder-CEO Larry Fink, is the largest asset manager in the world with approximately $10 trillion in assets under management as of 2025. The 13F-HR captures BlackRock's direct US-equity holdings, which span the iShares ETF family (BlackRock is the largest issuer of US-listed ETFs by AUM) plus institutional separate accounts and the firm's own balance-sheet positions.
The disclosed book is structurally different from a hedge fund's: BlackRock's positions are largely market-capitalization-weighted (because the underlying ETFs track major indices like S&P 500, Russell 1000, MSCI ACWI), meaning the top holdings mirror the market - Apple, Microsoft, NVIDIA, Alphabet, Amazon, Meta dominate by weight not because BlackRock is making active calls but because those names are the largest constituents of the indices BlackRock's ETFs track. The 'positions' in BlackRock's 13F are functionally proxy votes - the firm controls voting rights on billions of shares and uses that influence in corporate governance.
For retail traders, BlackRock's 13F is less useful as a stock-picking signal and more useful as a benchmark-positioning reference. The interesting signal is in the smaller positions and in the proxy-voting record: when BlackRock files specific shareholder proposals or breaks with management on ESG-related votes, the implications for portfolio companies are larger than the position size implies. The Larry Fink annual letter to CEOs (published each January) is often a more market-moving document than any 13F filing.
