On this episode of Stock Movers: Listen for comprehensive cross-platform coverage of the US market close as heard on Bloomberg Television, Bloomberg Radio, and YouTube with Romaine Bostick, Katie Greifeld, Carol Massar and Tim Stenovec. - Amazon (AMZN) shares surged the most since 2012 after the company reported accelerating cloud-computing revenue, easing investors’ concerns that it won’t produce a return on huge expenditures to meet the booming demand for artificial intelligence. - Apple (AAPL) tumbled by the most in 16 months after component shortages weighed on the company’s sales forecast, signaling that industrywide supply constraints are taking a bigger toll than anticipated. The disappointing forecast sent Apple shares down as much as 9.5% to $301.83 at the market open on Friday, their biggest intraday drop since April 3, 2025. - Roblox (RBLX) shares tumbled by as much as 26% as trading got underway in New York, the largest intraday decline in roughly four-and-a-half years, after the gaming company reported second-quarter daily active users that missed analysts’ expectations, reflecting the ongoing impact of new child-safety measures.See omnystudio.com/listener for privacy information.
