Blalock Williams, LLC holds a diversified book of 154 reported positions worth $154.3M as of Q2 2026 (disclosed Aug 7, 2026, a ~38-day 13F lag). This quarter they opened Ish Intl Ctry Rot Act ETF and trimmed Ishares S&P 500 Value ETF. Their largest long position is Ishares Core S&P 500 ETF at 8% of the reported non-option book. Cloning the disclosed picks since 2025 would be +10% (+11.3%/yr). That is a simulation of the disclosed long book, not audited returns.
The reported book (valued from quarter-end) returned +22.9%, a 13.1-point gap that is the cost of the ~38-day 13F disclosure lag a real follower can't avoid.
Growth of $10,000 cloning Blalock Williams, LLC's disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~38 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.
