Cathie Wood, the renowned growth investor, is known for her investments in disruptive tech stocks. While Amazon is not typically one of her top picks, her investment firm, Ark Invest, recently started buying shares of the e-commerce giant. Wood is particularly attracted to Amazon's focus on artificial intelligence (AI) and its potential for driving growth. The company's emphasis on "Day 1" and its position as the largest cloud-computing company give it a unique advantage for AI development. Furthermore, Amazon offers practical AI services through its Amazon Web Services (AWS) platform.

The recent decline in Amazon's stock price following its second-quarter report presented a buying opportunity for Wood, who purchased shares across her ETFs. Despite the rebound, the stock is still trading at a historically low valuation, making it an attractive investment. In addition to AI, Amazon has various opportunities in e-commerce, advertising, streaming, and healthcare. Overall, this presents a rare chance to buy into Amazon at a discounted price.
