Weekly Roundup: Amazon Soars, Roblox Drops, Chipotle Slides

On this episode of Stock Movers, we look at some of the week's biggest gainers and decliners:

- Amazon (AMZN) shares surged after the company reported cloud-computing revenue accelerated for a fifth straight quarter, easing investors’ concerns that it won’t produce a return on huge expenditures to meet the booming demand for artificial intelligence. 

- 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.

- Chipotle (CMG) raised its annual guidance after bringing back its popular honey chicken and overhauling its rewards program. The chain now expects sales from locations open at least 13 months to rise in the low single-digit range this year, Chipotle said Wednesday. An earlier forecast called for the metric, known as comparable sales, to be about flat.
