BSE replaces Wipro in Nifty 50: What drove the index reshuffle?
NSE said BSE will replace Wipro in the Nifty 50 effective after Sept. 30, following NSE’s semi-annual index review. NSE cited BSE’s six-month average free-float market cap meeting the 1.5x threshold versus Wipro. BSE shares are up about 37% YTD in 2026, while Wipro is down about 29.5%.
How this was made
The 30-second read
Why it matters
BSE’s inclusion and Wipro’s removal are driven by index methodology (BSE’s free-float market cap reaching at least 1.5x Wipro’s), which should trigger passive portfolio rebalancing around Sept. 30.
Market read
This is a benchmark composition change with likely mechanical effects on passive funds tracking Nifty 50, plus a sentiment signal about relative strength between capital markets and IT services.
What to watch
Actual flow size depends on each fund’s tracking methodology, cash management, and whether the change is implemented via futures, swaps, or cash rebalancing.
Background
Nifty 50 constituents are selected using free-float market capitalization averaged over six months, with liquidity and eligibility rules; NSE runs routine semi-annual index reviews.
Ticker impact
NSE confirmed Wipro will be removed from the Nifty 50 from Sept. 30 as BSE’s free-float market cap rises above the inclusion threshold.
Downward pressure or relative underperformance around Sept. 30 rebalancing, especially if passive selling is concentrated.
The text links the change to index methodology and highlights that index-tracking funds must rebalance, which typically translates into mechanical selling for the removed constituent.
Market effects

Supports India domestic equity inflows narrative via exchange beneficiaries.
Affects global passive and systematic investors tracking Nifty 50, potentially shifting cross-border flows between constituents.
