What this means for GCT
GCT is not showing a cluster buy or a step-change versus its own baseline, so what the window amounts to is selling only. Unusual selling. Head of Brand Center sold 68% of their stake. None of it was executed under a pre-arranged Rule 10b5-1 plan, so the timing was the insider’s own choice — $1M–$5M of discretionary selling in total.
