Apple shares stall as new $3,499 headset still to prove 'a must-own device'

Much will depend on the development of a “killer app” for the Vision Pro virtual reality headset, said one analyst.

Apple's new Vision Pro virtual reality headset is displayed during Apple's Worldwide Developers Conference at the Apple Park campus in Cupertino, California.

The stock market’s cool response to the launch of Apple’s mixed-reality headset left investors pondering what will provide the next push for a rally that has propelled the shares into record territory.

Having hit an all-time peak in the hours leading up to Monday’s product event, shares in the iPhone maker have slipped and eased further in the latest session, as analysts said the eye-popping price of $3,499 (€3,274) for the Vision Pro headset would limit its mass-market appeal.
