Earnings from four Magnificent Seven members — Amazon $AMZN, Apple $AAPL, Meta $META Platforms, and Microsoft $MSFT — will command investor attention this week, as Wall Street looks for clues about whether the pace of AI investment is moderating or holding firm. The results come after Alphabet $GOOGL's earnings last week disappointed investors. Ken Mahoney, CEO of Mahoney Asset Management, said the central tension is a difficult one for markets. "The biggest risk is the continuation of the spend," Mahoney told CNBC. "And then the problem is, if they do listen to shareholders and wind down a little bit of that spend, or reduce the growth of that spend, then the rest of the market is not going to like it."
