Amazon.com Inc.'s shares surged after its recent earnings report highlighted rapid growth in its cloud division, Amazon Web Services. The stock hit its best day since 2012, driven by better-than-expected revenue from the cloud business. However, the rally has since stalled, with the stock falling over 10% from its early August peak. Analysts note that the company's ability to sustain this growth will be crucial for regaining investor confidence. Concerns over AI competition, rising interest rates, and market uncertainty have weighed on the stock's performance. Despite these headwinds, Amazon's cloud division remains a key driver of its long-term growth prospects.
