Robot maker Unitree's stock jumps sixfold in first day of trading

Unitree Robotics opened at 1,100 yuan per share on Shanghai's STAR Market — 629% above its 150.80 yuan launch price. The humanoid-robot maker's first trade valued it above 366 billion yuan, roughly six times what investors paid in the IPO. Unitree raised 6.1 billion yuan selling 10% of itself. Whether that price holds — shares can only move 20% a day — is the question.
