Strategy in plain words

auto-generated from filings

FLOW TRADERS U.S. LLC is a market maker — positions are inventory, not bets, running a $3.16B US long book across 985 positions.

The portfolio is moderately concentrated (top 10 ≈ 33% of the book). Turnover is high — positions rotate quickly, so individual names matter less than the process. Current anchor positions: STATE STREET SPDR EURO STOXX, VANGUARD FTSE EUROPE ETF, STE STR SPDR PT DW EU ETF, VANGUARD FTSE PACIFIC ETF, ISHARES CORE MSCI EUROPE ETF.

Over the last 9 quarters its long book ran on average 0.2pp per quarter ahead of 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.
