Bezos Sells $4 Billion in Amazon Shares After Blockbuster Earnings

Amazon founder Jeff Bezos plans to sell approximately 15 million Amazon shares valued at over $4.07 billion, according to a Form 144 filing with the U.S. Securities and Exchange Commission.

The sale comes just days after Amazon reported stronger-than-expected second-quarter results, fueling a surge of more than 22% in its shares over the past week.

While insider stock sales are common among founders, the timing prompted CNBC's Jim Cramer to describe the transaction as a 'buzzkill' for investors celebrating the company's latest financial performance.
