"Microsoft's Game-Changing Acquisition: Activision Blizzard Deal Sends Shockwaves Through Wall Street"

Microsoft has completed its merger with Activision Blizzard, its largest deal in history, despite opposition from the U.S. Federal Trade Commission. The company also faces a $28.9 billion back-tax claim from the IRS. Arm Holdings, the chip designer, received positive ratings from major brokerages following its IPO, with optimism around its plans to generate revenue through royalty fees and expand its presence in cloud and automotive markets. On the other hand, Netflix saw its rating downgraded by Wolfe Research due to concerns about future growth and revenue expectations.
