Amazon.com Inc (NASDAQ:AMZN) shares are pulling back Tuesday. Amazon founder Jeff Bezos revealed plans to unload a substantial block of shares, casting a shadow over a stock that had been building meaningful upward momentum heading into the session.

Amazon (AMZN) stock rose over 5% as analysts highlighted a massive $496B AWS backlog and strong cloud profitability driving long-term AI infrastructure growth.

Jeff Bezos plans to sell $4.07 billion in Amazon stock, prompting Jim Cramer to call the move a “buzzkill.”
