Rakuten Securities, Inc.'s disclosed holdings carry a Herfindahl concentration index of 0.080 — mathematically equivalent to about 13 equally-sized positions, well below its 914 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 8.49), 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.
