If one takes June - July 2020 as the base from where this bull run started. Amongst the first to gain were stocks like Ashok leyland, Tata motors, Eicher motors. There was good enough reason for it, all these companies get a significant part of their sales from either heavy commercial vehicles or light commercial vehicles. Sales of LCV and certain other auto segments is an indication of the economic situation on the ground. Demand for large commercial vehicles would only increase when there is higher economic growth as more goods get moved from one place to another when the economy is doing well. So it is LCV and HCV which are the lead indicators of what is in store for the economy. But behind the finished automobile product there is a huge supply chain, right from an auto ancillary unit making forgings, to a tyre maker. Rather than look at one segment it would be worthwhile to look at select stocks which form the part of the chain. The reason, when LCV will indicate good numbers, then means subsequently there would be better car and two wheeler numbers.
