How the value is spread

The two largest, Reliance Industries and Bharti Airtel, are 85.4% of the combined ₹35,87,712 cr. More than half of the theme's value sits in two companies, so the theme mostly moves with them. Counting only the 23 companies whose main business this is (combined ₹17,96,003 cr), the largest two, Bharti Airtel and Vodafone Idea, are 78.5%.

Each block is one company, largest first. This list is not weighted, so nothing caps one company's share.
