IBKR Return Day-1 residual (stock − beta × S&P 500) -2.0% MEDIUM
IBKR Return 5-day cumulative residual -3.0% (FOLLOW-THROUGH) Q2 operating strength is already public via monthly metrics and was largely priced in the July 1 jump and the run to all-time highs (~$97 before easing to ~$91.70), so a well-telegraphed double-beat is a classic sell-the-news setup. The bigger swing factor — NII — faces out-period headwinds: NIM compression (1.88%→~1.82%) plus management's own sensitivity (~-$80M annualized NII per 25bp USD cut) means a dovish Fed path pulls 2H26/FY27 NII and EPS estimates down even after a Q2 beat, while softening commission-per-order and a marketing-spend margin drag reduce beat quality. Against a rich near-highs valuation, that biases the initial dip to follow through lower rather than recover. LOW
