In the latest installment of Yahoo Finance's Good Buy or Goodbye, Jared Blikre is joined by Constellation Research Founder and Principal Analyst R "Ray" Wang to review Magnificent Seven tech stock components Amazon (AMZN) and Microsoft (MSFT). Wang explains his bullish case for Amazon is enhanced by the diversity of the online retailer's digital stream of income and its venturing into AI. "They've done $200 billion of investments and capital. that means the free cash flow has been really bad, but we're now on the other end of that," Wang says.
