Boeing (BA) shares are sliding this morning after the FAA grounded dozens of 737 Max 9s after an Alaska Airlines (ALK) flight was forced to perform an emergency landing Saturday when a piece of the aircraft blew off the side of the aircraft. Boeing's decline is weighing on both the airline sector and the overall market. Yahoo Finance trending tickers include Harpoon Therapeutics (HARP), XPeng (XPEV), and Zoom Video (ZM).
