Strategy in plain words

auto-generated from filings

Rainwater Charitable Foundation is a wealth-management firm allocating client money, running a $193.7M US long book across 4 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 TOTAL STOCK MKT ETF, VANGUARD LONG-TERM TREASURY, FRANKLIN FTSE JAPAN ETF, VANGUARD REAL ESTATE ETF.

Over the last 9 quarters its long book ran on average 1.2pp per quarter behind the S&P 500, beating the index in 3 of 9 quarters. Its holdings are mechanical (indexing / client flows), so position changes carry no stock-picking signal.
