The portfolio is moderately concentrated (top 10 ≈ 43% of the book). Turnover is high — positions rotate quickly, so individual names matter less than the process.

Over the last 6 quarters its long book ran on average 0.2pp per quarter behind the S&P 500, beating the index in 3 of 6 quarters. Signal value of individual moves is limited — treat changes as weak evidence.
