AI Holders Summary · Q1 2026

PartnerRe left its 1,397,745 HYG shares untouched, yet the two holders above it moved violently in opposite directions. Grimes & Co. Wealth Management bought an estimated $166.9 million, expanding to $175.1 million and 21.7% of tracked institutional value, while Ocean Park Asset Management sold roughly $56.1 million and finished at $159.0 million, or 19.7%.

That split is the ownership story for HYG in the quarter ended June 30, 2026. Grimes, Ocean Park and PartnerRe together control about 55.3% of the $806.5 million tracked across 147 institutions, so the fund's apparent breadth hides a concentrated top tier. Smaller additions from Acasta Partners and Worth Asset Management support the buying side, but they are secondary to a direct transfer of influence from Ocean Park toward Grimes.

That concentration changes how the holder count should be read. HYG appears broadly distributed across 147 institutions, but more than half of the reported value sits with three firms. The quarter did not produce a uniform institutional view; it produced a reshuffling at the top, with Grimes taking the leading position as Ocean Park reduced exposure and PartnerRe held steady.

The next group leans modestly toward accumulation. Acasta Partners bought an estimated $7.8 million, nearly doubling its shares to 198,841. Worth Asset Management added roughly $3.4 million, Stairway Partners $2.3 million and Redhawk Wealth Advisors $1.2 million. KWMG also purchased about $1.1 million and now holds $25.2 million. These additions show that Grimes was not the only buyer, but their combined scale remains a fraction of its move.
