Shares in Apple (NASDAQ:AAPL) edged down slightly in after-hours trading after the stock jumped to a record-high close of $183.79 on Monday.

The surge comes after Apple unveiled its new Vision Pro mixed reality headset at its annual developers conference last week. The product was the company’s first new hardware launch since 2014.

Despite its eye-watering price tag of $3,499, the Vision Pro is widely seen as a key moment in the evolution of virtual reality headsets, with experts hoping that Apple’s reputation for design and brand loyalty will help entice consumers.

However, some analysts have flagged lingering problems for Apple. On Monday, analysts at UBS downgraded their rating of the stock, citing in part an expected slowdown in unit growth of the firm’s iPhone device.
