Maintain the current EMR position with disciplined tiered execution rather than chasing at $158, where the unresolved $0.68 Street-vs-guidance EPS gap and failed $164.85 Bollinger rejection present insufficient risk-reward. Add 25% of position on pullback to $144-150 (50 SMA zone) with flexibility to increase to 30-35% if support holds with expanding volume on the bounce, and stop at $140.50.
