Mizuho Securities USA LLC's disclosed holdings carry a Herfindahl concentration index of 0.019 — mathematically equivalent to about 51 equally-sized positions, well below its 690 actual disclosed holdings. That gap points to a strategy built around a small core of high-conviction bets rather than broad diversification.
Position sizes vary widely across the portfolio (a coefficient of variation of 3.53), with a handful of outsized bets alongside many smaller positions.
No strong tilt toward either adding to existing winners or initiating outsized new positions was observed in the latest reported quarter.
