Why Rocket Lab Stock Just Crashed

High-flying Rocket Lab (NASDAQ: RKLB) stock tumbled down (almost) to Earth Tuesday after Bleecker Street Research -- which publishes "public short ideas" for its parent company, stock-shorting firm Bleecker Street Capital -- warned that Rocket Lab's highly anticipated Neutron medium-lift vehicle won't launch for "a long, long time." As of 1:15 p.m. ET, Rocket Lab stock is down 9%.
