Sorting and tie-breaks
Companies are sorted by the unrounded period average, descending. A true tie at available precision is broken by the higher 31 December full market capitalisation, then by a documented deterministic tie-break. A tie that appears only after rounding is not a real tie. No tie arose in this edition.
The validation band
Market capitalisation is calculated for every eligible main-board company, not only the 1,000 shortlisted names. An internal top-1,500 watch universe is maintained, at least the top 1,200 are validated, and ranks 950–1,050 receive heightened human review — because that is where a small data error would change membership of the list.
What the ranking is not
- It is not a measure of quality, governance, performance or prospects.
- It is not a valuation opinion. Market capitalisation is what the market paid, not what a company is worth.
- It is not a measure of India's total enterprise wealth: cross-holdings mean the sum double-counts.
- It is not current. The window closed on 31 December 2025.
- It is not the official exchange or SEBI list, and it determines no company's regulatory obligations.
