Eddie Hebert 55b25bdd3f MAINT: Set dividend effective date to ex_date.
The price shock occurs on the effective_date. Had changed the effective_date to
be day before the ex_date with the belief that pipeline was applying values up
and until the effective_date, but the lookback windows apply before the
effective_date. Thus, the price shock calculation should still use the previous
days data but be dated on the ex_date to stay aligned with splits and
merger dating.
