Amazon is set to report fourth-quarter results late Thursday, with the tech giant's stock trading slightly lower vs. 12 months ago. The results will reflect a key holiday quarter for the tech giant's e-commerce business, but Wall Street's eyes will be on AI progress and the company's Amazon Web Services cloud business. "The focus here remains almost squarely on AWS exit growth and margin, with growing buy-side expectations on segment sales growth that add risk to the print," William Blair analysts Dylan Carden and Arjun Bhatia wrote to clients Wednesday.
