Direction before market-wide shocks
Before the market's biggest moves, did the member's trades point the right way?
What would look suspicious
An informed trader's trades just before a market-moving event point in the direction of the coming move.
Statistic
Hit rate over episodes (net dollar direction in the five trading days before each shock)
Inference
Exact binomial test, Clopper-Pearson interval, sign-flip permutation of the magnitude-weighted statistic
Decision rule
Fits if the one-sided exact p-value is significant after Holm and BH adjustment. Does not fit if the hit rate is below one half and T4 does not fit. Otherwise open question.
Equivalence margin δ
10 points above a coin flip (fixed before seeing the data)
Inputs
Limitations
Few market-wide shocks fall within any one member's trading; most members have small episode counts.
