Nifty Auto Index: Key Drivers

  • Shares of four-wheeler companies such as Maruti, Ashok Leyland, and Mahindra & Mahindra have risen by up to 50% this year on the bourses as sales improved amid easing semi-conductor shortages and increased demand. 
  • Except for two-wheelers, the rest of the auto industry is extremely sensitive to changes in the overall economic outlook and interest rates due to the size of its ticket. Consumer sentiment is important in high-priced purchases. Furthermore, the outlook for commercial vehicles is influenced by general economy. 
  • Automobiles are either a user’s discretionary purchase or used for economic purposes. The auto industry is cyclical in nature, with periodic downturns. Economic activity, interest rates, available financing options, wage/salary growth, and the regulatory environment all influence cycle sensitivity. 

Nifty Auto Index: Auto Eco-System 

  • Original Equipment Manufacturers (OEMs) are the big players in automotive ecosystems. Naturally, they have an advantage and bargaining power than the other players. Maruti Suzuki, Bajaj Auto, and other OEMs are examples.
  • The auto ancillaries are vendors of different components to OEMs and are part of the ecosystem. There are numerous auto ancillaries that produce tyres, engines, fasteners, forging components, crankshafts, batteries, and so on. Motherson Sumi, Sundram Fasteners, Gabriel India, Exide Industries, and MRF are among the listed auto ancillaries.
