Institutional cluster: 4 buyers, 4 sellers (mixed)
Actionable Insight ◆ Mixed

Mixed institutional signals suggest uncertainty ahead. The Citadel doubling is a bullish signal, but offset by significant trimming from other knowledgeable funds. Monitor for upcoming catalyst (earnings, product milestones) to resolve direction. The 45-day 13F lag means positions may have already changed.
