Game Theory Scenarios
Neutral— Wait & Watch
Institutional and insider signals mixed, neutral
Signal Basis
Institutions net added $9.07B in value, with 178 new buys vs 127 exits, but buyer and seller counts both stood at 1,387. Insiders recorded 3 sells worth $21.1M and no buys over 90 days.
Confirmation
Sustained insider selling combined with steady institutional inflows would confirm the neutral outlook.
Invalidation Risk
A decisive shift by either side—institutional net selling or a cluster of insider buys—could break the stalemate.
This game-theory analysis is AI-assisted and derived from institutional holders' SEC EDGAR filings, covering historical data only. For informational purposes, not investment advice — source filings linked below.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.
