Apple Inc's shares on Monday hit a record high for the first time in 17 months, as the stock got a boost ahead of its annual software developer conference where it is expected to launch a mixed-reality headset.

The world's most valuable listed company was last up 1.2% at $183.25 in early trading. The headset would be Apple's first big move into a new product category since the introduction of Apple Watch nine years ago.

Apple is among a handful of megacap tech-focused firms that have underpinned main stock indexes this year, as enthusiasm over advances in AI helps fuel a rally. Apple shares have jumped nearly 40% in 2023, compared with an 11.5% rise in the benchmark S&P 500.
