Ashok Leyland shares jump over 10% in biggest single-day gain since April; here's what lifted the stock

Ashok Leyland reported movement of 10%. Those are the figures as filed — what moves the price is how they sit against what the market already expected, not their absolute size.

Against that, the stock is +10.5% on the day at ₹170.21, and has returned -3.8% over three months. It sits 20% below its 52-week high. The auto sector has moved -5.8% over the same period, so Ashok Leyland is running 2.0 points ahead of its peers.

This is an Input cost / crude event. India imports most of its crude, so input costs pass through to margins downstream and to the rupee. Producers and consumers of the same input move in opposite directions. On the day the stock is +10.5%, so the tape moved decisively on this.
