Our maximum likelihood estimation reveals that high announcement returns are not a manifestation of a large announcement premium. Rather, they originate from positive return innovations that are not averaged out in-sample. We show that models with an announcement premium cannot explain the joint patterns of return and volatility over announcement days. We find that traditional models, which do not feature such a premium, can.
