Nifty 50 to see BSE replace Wipro in September index reshuffle
NSE Indices said BSE will replace Wipro in the Nifty 50 after its semi-annual review. The change takes effect after the close on 29 Sept 2026, for 30 Sept 2026. BSE’s six-month average free-float market cap was Rs 1,40,879 crore versus Wipro’s Rs 55,930 crore. Other Nifty indices will also be reconstituted.
How this was made
The 30-second read
Why it matters
Wipro’s removal from Nifty 50 and BSE’s addition are likely to trigger passive rebalancing flows, with timing anchored to the 29 Sep 2026 close and 30 Sep 2026 effective date. The reshuffle also cascades into multiple other Nifty indices and sectoral indices, broadening potential flow effects beyond the two headline names.
Market read
Traders in India index-tracking products should monitor reconstitution-window positioning in the affected constituents, especially Wipro (deletion) and BSE (addition).
What to watch
Actual trading impact depends on how quickly index funds implement changes (some trade ahead of effective dates), derivative hedging activity, and whether the affected names have high benchmark-tracking ownership.
Background
The article describes NSE Indices’ semi-annual index maintenance, where Nifty constituents are reselected based on six-month average free-float market capitalization and eligibility rules (including NSE F&O availability).
Ticker impact
NSE Indices will replace Wipro in the Nifty 50 effective 30 Sep 2026 after its free-float market cap falls below the 1.5x threshold.
Likely short-term downward pressure into the reconstitution window, followed by normalization after index funds rebalance.
The article specifies Wipro’s exclusion from Nifty 50 and Nifty 50 Equal Weight, plus the effective close date, which typically triggers predictable passive rebalancing flows.
Market effects
Broader index reshuffle changes constituents across Nifty 100, Next 50, Midcap 150, 200, Smallcap 250, and several sectoral indices, which can shift relative flows among large-cap and sector ETFs.
Primarily India-listed passive flow effects; may influence liquidity and spreads in affected names during the reconstitution window.
Limited direct global impact, but can affect India equity index-tracking strategies and cross-asset risk models that include Indian benchmarks.
Counterpoint
If liquidity is high and passive flows are well-hedged, the net price impact may be smaller than expected, with most of the effect already priced by index-tracking desks.
