iPhone launches have generally been a positive catalyst for Apple shares, which have gained nine out of 13 times in the 60 days following such an event.

“Apple stock has typically traded up into such launch events, pulled back slightly after the event, and then recovered 60 days post the event,” a team of New York-based Bank of America Merrill Lynch analysts said last week in a note to clients.

Tuesday’s event will be followed closely by Wall Street analysts, who will be tweaking their models once the details of the new products are revealed.

The Bank of America Merrill Lynch analysts noted the 2018 launch event may have been influenced by a number of factors which have the potential to strike again this year, including a higher price for new iPhones, the U.S.-China trade war and a slowing global economy. Apple shares fell 7 percent in the 60 days following last year’s event.

Many analysts expect Apple to keep its pricing the same as last year even though tariffs on products made in China are set to go into effect on Dec. 15.

“We suspect that Apple will likely maintain current iPhone prices on its 3 new models ($749/$999/$1099), and may keep memory and storage content the same as last year – despite dramatic cost declines – providing margin cushion to help offset potential tariffs or required promotional activity,” wrote Bernstein analyst Toni Sacconaghi from New York.
