Nio is trading 4.05% lower at $3.44 as slower delivery growth raises future revenue concerns. - September deliveries rose 7.7% year over year, versus 14% growth in August; an October 12 report linked the ongoing sell-off to slowing business momentum. - U.S.-listed ADRs were also caught in the sell-off, while the broader market was nearly flat. - No specific October 12 company announcement or analyst action was identified; Goldman’s October 9 upgrade was positive, not a clear catalyst.
