The iPhone X will be available on Nov. 3 at a base model price of $999.
Ives initiated a price target range of $190 to $200 for Apple shares, representing 24 percent upside at the midpoint to Friday's close.
"In addition to a more robust upgrade in terms of form/function on iPhone X, we believe iPhone units will benefit from a massive iPhone installed base that is ~2 years old (or older)," he wrote.
He estimates there are more than 350 million users with an iPhone that is at least 2 years old, which is a big upgrade opportunity for Apple. He cited the firm's October survey, which revealed 93 percent of iPhone owners who plan to upgrade their phone during the next year will buy another iPhone.
"The last time we saw pent up installed base demand and consumer feedback mirroring (or close to) this was around the iPhone 6, which ultimately became a critical and unprecedented successful launch period for Apple," he wrote. "Our model assumes Apple sells more iPhones in the 12 months following the iPhone X and iPhone 8/8+ launch than the peak iPhone 6 upgrade cycle."
Ives predicts Apple will sell 265 million iPhones in fiscal 2018 versus the record 231 million iPhones in fiscal 2015.
