Resona Asset Management Co.,Ltd.'s disclosed holdings carry a Herfindahl concentration index of 0.016 — mathematically equivalent to about 62 equally-sized positions, well below its 786 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 3.42), 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.

The data shows Resona Asset Management actively reduced share counts across the semiconductor complex this quarter — Micron, AMD, Intel, Applied Materials and Lam Research were all trimmed, along with Nvidia and Alphabet — yet the sharp price appreciation in those names pushed their portfolio weights higher regardless (Micron from 0.57% to 1.72%, AMD from 0.52% to 1.29%), while the top position, Nvidia, ended roughly flat at 6.93%. At a turnover ratio of just 17.8%, these read as measured skims rather than exits, a pattern consistent with trimming into strength; Broadcom was the lone add, moving from 2.14% to 2.52%.
These flows line up with what appears to be an AI-infrastructure-led market phase, in which memory and compute names re-rated sharply enough that passive weight drift overwhelmed active selling — an inference drawn from limited holdings data, not a confirmed causal claim about underlying macro drivers.
The structural tension here sits between statistical breadth and effective concentration: 786 positions and an HHI of roughly 0.016 signal deep diversification, yet Information Technology absorbs 36.96% of the book and Nvidia alone holds near 7%. Should the crowded AI trade unwind, more than a third of the portfolio is exposed — and this quarter's trims appear far too small to materially deflate that positioning.
