Strategy in plain words
auto-generated from filingsWind River Trust Co is a wealth-management firm allocating client money, running a $265.2M US long book across 11 positions.
The portfolio is extremely concentrated — the top 10 positions are almost the whole book. The book barely moves quarter to quarter — a patient, low-turnover holder. Current anchor positions: VANGUARD TOT WORLD STK ETF, ISHARES RUSSELL 1000 VALUE E, ISHARES RUSSELL 3000 ETF, SS SPDR S&P 500 ETF TRUST-US, ISHARES MSCI ACWI ETF.
Over the last 9 quarters its long book ran on average 0pp per quarter behind the S&P 500, beating the index in 4 of 9 quarters. Its holdings are mechanical (indexing / client flows), so position changes carry no stock-picking signal.
