Game Theory Scenarios
Insiders and institutions exit AMT in unison, bearish trend confirmed
Signal Basis
Institutional net value dropped $2.73 billion despite a slight buyer majority; insider selling outpaced buying by 29-to-1 in the last 30 days.
Confirmation
Continued institutional outflow or a new spike in insider selling would reinforce the downtrend.
Invalidation Risk
A cluster of insider buys or a sharp reversal in institutional inflow would invalidate this bearish call.
