Strategy in plain words

auto-generated from filings

GTS SECURITIES LLC is a market maker — positions are inventory, not bets, running a $2.83B US long book across 1482 positions.

The portfolio is moderately concentrated (top 10 ≈ 26% of the book). Turnover is high — positions rotate quickly, so individual names matter less than the process. Current anchor positions: INVESCO QQQ TRUST SERIES 1, ISHARES CORE S&P 500 ETF, SS SPDR S&P 500 ETF TRUST-US, NVIDIA CORP, MICROSOFT CORP.

Over the last 9 quarters its long book ran on average 0pp per quarter ahead of the S&P 500, beating the index in 5 of 9 quarters. Its holdings are mechanical (indexing / client flows), so position changes carry no stock-picking signal.
