§ 03 · THE TWO SIGNAL

AC read

Two Sigma's latest 13F filing reveals a fund operating at peak tactical velocity, with an extraordinary 88% quarterly turnover rate that underscores its algorithmic, high-frequency approach to portfolio management. Despite managing a massive $38.5 trillion in assets across 78 positions, the fund maintained remarkable trading discipline by exiting zero positions while simultaneously establishing 21 new stakes. This behavior suggests Two Sigma's quantitative models identified compelling entry points across multiple sectors, with the fund's diversified Herfindahl-Hirschman Index of 0.021 indicating risk is spread broadly rather than concentrated in a handful of bets.
