Strategy in plain words
auto-generated from filingsWINTON GROUP Ltd is a quantitative fund whose holdings reflect models, not opinions, running a $2.85B US long book across 1080 positions.
The portfolio is broadly diversified across 1080 positions (top 10 only 15%). Turnover is high — positions rotate quickly, so individual names matter less than the process. Current anchor positions: BERKSHIRE HATHAWAY INC-CL A, INVESCO SENIOR LOAN ETF, GE VERNOVA INC, BOOKING HOLDINGS INC, NETFLIX INC.
Over the last 9 quarters its long book ran on average 1.3pp per quarter behind the S&P 500, beating the index in 4 of 9 quarters. Signal value of individual moves is limited — treat changes as weak evidence.
