Jim Cramer, the host of CNBC's Mad Money, has advised investors to take profits on their Big Tech investments, highlighting the importance of profit-taking even when it's difficult to let go of shares from the 'Magnificent Seven', a group of top-performing tech companies. He mentioned that despite potential regrets of selling these stocks, the current market conditions might present a lower buy-in opportunity. Cramer specifically pointed out Amazon (AMZN) for its Prime Video service's revenue potential and Tesla (TSLA) for its future growth beyond electric vehicles.
