Companies must have a minimum listing track record on the NSE, unless they are newly listed and meet fast-track eligibility norms.
Periodic review and rebalancing
The index is reviewed semi-annually. During this process, eligible companies may be added or removed based on updated market capitalisation rankings and liquidity conditions.
