Apple's stock is typically under pressure the day of its closely watched media events, and Monday was no exception.

Shares of the tech giant fell 1.2 percent as CEO Tim Cook announced a new strategy based around services. But key details such as pricing and content were lacking, and Wall Street analysts thought it was a dud.

Despite the underwhelming event, Apple's stock performance Monday falls largely in line with how shares perform on average during the day of its event, according to data from Kensho, a hedge fund analytics tool.
