BlockBeats News, August 6th - As Amazon's stock price hit a record high on Monday, founder Jeff Bezos sold nearly $350 million worth of Amazon stock, marking his first stock sale of the year.

The transaction was disclosed in a Form 4 filing released after market close on Wednesday. The billionaire had indicated in another filing two days prior his plans to sell up to 15 million shares of Amazon stock, worth over $4 billion, with this sale representing only a small portion of that plan.

Even after this sale, Bezos still holds a significant lead with a 8.16% stake, remaining Amazon's largest shareholder.
