AI Holders Summary · Q2 2026

GCT Semiconductor Holdings shows zero institutional holders in the prior quarter's record and exactly two this quarter, both brand new. Independent Financial Group opened the substantial position — 49,250 shares worth $146,273, effectively the entirety of the stock's tracked institutional value. Kerr Financial Planning Corp opened a token stake alongside it: 10 shares, worth $30. Together they mark the stock's first appearance in this dataset's institutional ownership record.

A stock at the very start of its institutional record

With both positions dated to this quarter and no history to compare against, there's no rotation or trend to describe yet — only a first data point. Independent Financial Group's position is large enough to represent a genuine allocation decision; Kerr Financial Planning's is not.
