BSE 500

The BSE 500 (S&P BSE 500) is the broadest equity index maintained by Asia Index Private Limited on the Bombay Stock Exchange — comprising the top 500 companies by free-float market capitalisation listed on BSE, covering large-cap, mid-cap, and small-cap segments and representing approximately 92% to 95% of BSE's total listed market capitalisation. The BSE 500 is the BSE equivalent of the Nifty 500 — providing comprehensive coverage of the Indian equity market across all capitalisation segments in a single benchmark. The index is calculated using free-float market capitalisation weighting with semi-annual reviews, covering companies from the most liquid, largest blue chips down to the most investable small-cap companies within India's regulatory definition. The BSE 500 serves as the broadest available passive benchmark for assessing total Indian equity market performance — useful for portfolio managers wanting to evaluate whether their active selections have generated alpha relative to the entire investable market rather than just the large-cap segment. BSE 500-linked index funds and ETFs provide investors with the broadest possible exposure to India's listed corporate universe through a single, low-cost passive instrument — capturing the full spectrum of the Indian growth story from established large-cap leaders to high-potential small-cap emerging companies in a single diversified index structure.
