Amazon.com has reported disappointing third-quarter earnings, with revenue growth falling below expectations and expenses outpacing sales. This financial turmoil has resulted in a staggering $170 billion drop in market value and a 39% loss for shareholders over the past year. The company has revised its fourth-quarter growth forecast to just 2-4%, further unsettling investors already concerned about rising costs and the end of relationships with key sellers like Appario and Cloudtail, who contributed significantly to its sales revenue.
