BSE joins the Nifty 50, and Wipro exits at Tuesday’s close. IIFL Alt Desk estimates nearly $1.47 billion of combined gross flows across 12 stocks, with the rebalance coinciding with monthly expiry.
The Nifty rebalancing today puts BSE Ltd., Wipro Ltd. and 10 other stocks in focus as NSE Indices implements its September review at the close of trading.
The headline change is clear: BSE replaces Wipro in the Nifty 50, with the new composition effective September 30, 2026, after the September 29 close. NSE Indices said BSE’s six-month average free-float market capitalisation was ₹1,40,879 crore, compared with ₹55,930 crore for Wipro. BSE therefore met the stated 1.5-times requirement for replacing the smallest eligible constituent.
But the market event is broader than the BSE-Wipro swap. CNBC TV18, citing NSE and IIFL Alt Desk, lists six stocks with estimated inflows and six with estimated outflows. The six inflow estimates add up to $989 million, while the six outflow estimates total $479 million. Combined, that implies roughly $1.47 billion in gross estimated flows.
That $1.47 billion is a calculation from the reported stock-level estimates, not an NSE figure or a confirmed amount of institutional orders.

Why today’s Nifty rebalancing matters
Index changes can prompt passive and benchmark-sensitive portfolios to adjust positions around the implementation date. Tuesday’s event also coincides with the Nifty 50 monthly expiry, according to CNBC TV18’s September 29 market update.
The broader market backdrop is weak. The Nifty 50 fell 1.56% to 22,780.25 on Monday, while the Sensex declined 1.52%. Reuters reported that both benchmarks were near six-month lows after seven consecutive weekly declines, with losses of nearly 6% over that period.
That means index-related demand will be meeting a market already dealing with broader selling pressure.
Six stocks facing estimated inflows
CNBC TV18’s September 29 report, citing IIFL Alt Desk, gives the following estimates:
| Stock | Estimated inflow | Rebalancing change |
|---|---|---|
| BSE | $595 million | Nifty 50 inclusion |
| Vedanta Aluminium Metal | $146 million | Nifty index inclusion |
| Adani Enterprises | $69 million | Nifty 50 weight increase |
| Polycab India | $65 million | Nifty index inclusion |
| Hitachi Energy India | $57 million | Nifty index inclusion |
| Vodafone Idea | $57 million | Nifty index inclusion |
Combined IIFL Alt Desk inflow estimate: $989 million.
BSE: The largest estimated inflow
BSE has the biggest reported inflow estimate at $595 million.
Its Nifty 50 inclusion is confirmed by NSE Indices. The index provider said BSE’s six-month average free-float market capitalisation was about 2.5 times Wipro’s, comfortably above the relevant replacement threshold.
The $595 million figure, however, is an IIFL Alt Desk estimate, not a guaranteed amount of buying at the closing auction.
Vedanta Aluminium, Polycab, Hitachi Energy and Vodafone Idea
The broader reshuffle also brings Vedanta Aluminium Metal, Polycab India, Hitachi Energy India and Vodafone Idea into the Nifty 100 and Nifty Next 50 structure. NSE’s September review confirms those index changes.
IIFL Alt Desk estimates inflows of $146 million for Vedanta Aluminium Metal, $65 million for Polycab India, and $57 million each for Hitachi Energy India and Vodafone Idea.
Adani Enterprises has a separate catalyst
Adani Enterprises is estimated to see about $69 million of inflows as its Nifty 50 weight increases.
The stock also has a separate regulatory development. SEBI’s settlement order dated September 28 disposed of proceedings involving Adani Enterprises, Adani Power, Adani Ports and Adani Energy Solutions and their directors over alleged minimum public-shareholding violations. Business Standard reported a cumulative settlement payment of ₹1.48 crore, with the settlement made without admitting or denying the facts and conclusions of law.
That gives the stock a second potential source of trading interest beyond the index change.
Six stocks facing estimated outflows
The IIFL Alt Desk estimates cited by CNBC TV18 also identify six stocks facing outflows:
| Stock | Estimated outflow | Rebalancing change |
|---|---|---|
| Wipro | $152 million | Nifty 50 exit |
| Indian Hotels Company | $96 million | Nifty 100 exit |
| United Spirits | $63 million | Nifty 100 exit |
| Shree Cement | $62 million | Nifty 100 exit |
| REC | $59 million | Nifty 100 exit |
| Lodha Developers | $47 million | Nifty 100 exit |
Combined IIFL Alt Desk outflow estimate: $479 million.
Wipro: Largest estimated outflow
Wipro has the largest reported outflow estimate at $152 million following its Nifty 50 exit.
But Wipro is not leaving the wider Nifty structure. NSE Indices is adding it to the Nifty Next 50 from September 30.
This distinction matters because a stock can lose exposure from one benchmark while gaining exposure through another.
Indian Hotels, United Spirits, Shree Cement, REC and Lodha
Indian Hotels has the second-largest reported outflow estimate at $96 million, followed by United Spirits, Shree Cement, REC and Lodha Developers.
NSE’s September review removes these five from the Nifty 100. The broader reshuffle also changes the composition of the Nifty Next 50.
The changes therefore represent index repositioning across the broader Nifty structure rather than a universal removal from major benchmarks.
Why the $1.47 billion estimate needs context
The six IIFL inflow estimates total $989 million and the six outflow estimates total $479 million. Together, they equal $1.468 billion, rounded to $1.47 billion.
The figure is therefore best read as combined gross estimated flows, rather than a precise amount of money that will necessarily be traded.
Nuvama’s estimates also differ from the IIFL figures. For BSE, published reports put Nuvama’s estimate at more than $600 million, while Nuvama’s Wipro estimate is more than $200 million. That difference highlights how assumptions around passive assets, index weights and portfolio implementation can change the final number.
Why the Closing Auction matters
The implementation takes place at Tuesday’s close, putting the Closing Auction Session (CAS) at the centre of the event.
On August 31, the NSE recorded ₹39,718 crore of CAS turnover during the MSCI rebalancing, or nearly 22% of total cash-market turnover. Turnover during the session was also about 42 times the previous trading day’s level.
The September FTSE reshuffle later generated ₹16,613 crore of CAS turnover, the second-highest level since the mechanism was introduced. Business Standard also noted that CAS currently applies only to stocks in the futures and options segment.
Those earlier volumes do not predict Tuesday’s turnover. They show why the final trading window can become particularly important during a major index adjustment.
Institutional flows add another layer
Foreign selling is another variable for traders to watch.
Foreign portfolio investors sold a net ₹5,353.22 crore on Monday, while domestic institutional investors bought ₹5,189.02 crore, according to NSE data reported by Moneycontrol. The FII selling was the largest single-day outflow in September.
That means index-related buying and selling will be interacting with broader institutional positioning rather than occurring in isolation.

What traders should watch
Closing volume: A sharp rise in turnover near the close could signal heavier rebalancing activity, although volume alone cannot identify the buyers or sellers.
Price versus estimated flow: A stock receiving an estimated inflow does not automatically have to rise. Broader market selling, pre-positioning or company-specific news can dominate the effect.
September 30 follow-through: The next session will show whether any flow-related price moves persist after the new index composition takes effect.
📊 Nifty Rebalancing Alert
BSE enters Nifty 50 as Wipro exits.
IIFL Alt Desk estimates nearly $1.47 billion in combined gross flows across 12 stocks, based on six inflow and six outflow estimates.
The wider reshuffle affects the Nifty 100 and Nifty Next 50, putting Vedanta Aluminium Metal, Polycab, Hitachi Energy India, Vodafone Idea and other stocks in focus.
The actual market impact may differ as index positioning, expiry activity, FII/DII flows and stock-specific catalysts interact at the close.
Bottom Line
Today’s Nifty rebalancing combines a confirmed index reshuffle with a less certain set of estimated portfolio flows.
BSE replaces Wipro in the Nifty 50, while Vedanta Aluminium Metal, Polycab India, Hitachi Energy India and Vodafone Idea enter the broader Nifty 100 and Nifty Next 50 structure. IIFL Alt Desk estimates cited by CNBC TV18 point to $989 million of inflows and $479 million of outflows across 12 stocks, or about $1.47 billion in combined gross estimated flows.
The numbers should not be treated as confirmed orders. With monthly expiry, the Closing Auction Session and heavy FII selling all overlapping with the rebalance, the closing activity on September 29 and the September 30 follow-through will provide the clearer picture of how much of the expected repositioning the market actually absorbed.
