Ashok Leyland is trading 6.76% up at INR 164.45, with no reported company announcement on November 5 clearly explaining the sharp move. - October vehicle sales rose 23% year over year to 21,888 units; the company announced the figures on November 2. - The Nifty Auto index rose 1.16% on November 4 alongside a broader Indian-market rally. This may have supported sentiment, but available reporting does not directly attribute Ashok Leyland’s November 5 gain to it.
