JAC Motor hits daily limit again as Hefei plant, Huawei ties draw focus

The three-session limit-up run reflects positioning ahead of a specific catalyst — the HarmonyOS Smart Mobility event — rather than any disclosed change in JAC's fundamentals.

Whether the event delivers enough substance to hold those gains, or whether the move unwinds once the catalyst passes, is the open question.
