The cluster reveals deep institutional disagreement: large passive/sovereign exits (Norges, Capital World) suggest valuation or sector concerns, while active managers like Capital Group and RenTech are adding aggressively. Monitor upcoming earnings for catalyst that could resolve this divergence — a beat may validate buyers, while a miss could accelerate selling. The 45-day 13F lag means some positions may already be adjusted.
