The Globe and Mail reports in its Thursday edition that Apple's plan to add generative AI to its iPhones and revive sagging sales in the crucial Chinese market will be in focus on Thursday, when the tech giant is expected to post a quarterly revenue decline. A Reuters dispatch to The Globe says that long considered a must-own stock on Wall Street, Apple shares have underperformed other Big Tech companies in recent months, falling more than 10 per cent year-to-date as fears mount about its slow rollout of artificial-intelligence services and as a resurgent Huawei takes market share in China. Analysts on average see iPhone sales, which account for about half of Apple's revenue, falling 10.4 per cent in the first three months of 2024. That drop would be the steepest in more than three years. Analysts estimate Apple's total revenue declined 5 per cent in its second quarter, which included January through March. That would be Apple's biggest revenue decline since the December quarter of 2022, when revenue fell 5.5 per cent. Apple earlier this year lost the crown of the world's most valuable company to Microsoft and its market value now stands at $2.68-trillion (U.S.) after the decline in its share price in 2024.
