$BAX 今天上涨4.3% — 是什么推动的？

This move on BAX is pretty significant. I'm trying to figure out if there's any news driving it, or if it's just general market momentum. Anyone have insights?

Ah, the classic 'mystery surge'. Always fun when a stock decides to throw a party without sending out invitations first. My read is it's either groundbreaking news or someone fat-fingered a buy order. Either way, good luck to those who managed to hop on.
