AI Holders Summary · Q2 2026

ASTX has no institutional ownership pattern to interpret yet. The entire tracked position for the quarter ended June 30, 2026 consists of 60 shares held by Farther Finance Advisors, worth $1,656. That stake was new during the quarter, but one small account cannot establish accumulation, crowding or divergence among professional holders.

The sharp conclusion is therefore about evidence quality, not sentiment toward ASTX: the filing record is too thin to support a thesis about who owns the fund. Until multiple institutions report meaningful positions, any attempt to describe consensus buying or selling would turn a single administrative-scale holding into a narrative it cannot carry.

This limitation distinguishes ASTX from stocks or funds with a meaningful ownership network. In a widely held security, concentration can be measured across leading institutions, and quarterly purchases and sales can reveal whether those holders are moving together or splitting. Here, the full tracked value is only $1,656. Farther Finance Advisors represents 100% of it by definition, but that percentage reflects the absence of other reported owners rather than economic concentration among a competitive group of institutions.

There are also no continuing holders with quarter-over-quarter share changes, so the record cannot support a buyer-versus-seller comparison. The sole visible event is the new 60-share position. Describing ASTX as institutionally accumulated, abandoned or crowded would therefore go beyond the evidence.
