How Will Sensex and FTSE Rebalancing Impact Stocks and Market Flows Today
About the Index Rebalancing Event
Indian markets are set to witness heightened stock-specific activity as Sensex and FTSE indices undergo their scheduled rebalancing on December 19. Such rebalancing exercises typically trigger large passive fund flows, leading to sharp volume spikes and short-term price movements in the affected stocks.
According to available data, the Sensex will see the addition of InterGlobe Aviation, while Tata Motors Passenger Vehicles will be removed. Simultaneously, FTSE All World and FTSE All Cap indices will include select Indian stocks, driving incremental foreign inflows.
Key Changes in Sensex and FTSE Indices
🔹 Sensex addition: InterGlobe Aviation.
🔹 Sensex deletion: Tata Motors Passenger Vehicles.
🔹 FTSE All World and All Cap additions: Siemens Energy and HDB Financial.
🔹 FTSE All Cap additions: AB Lifestyle and Ather Energy.
Index inclusions generally result in buying by passive funds tracking these benchmarks, while deletions face selling pressure. As a result, price action on the rebalancing day often reflects flow-driven moves rather than fundamental shifts.
For traders navigating such event-driven volatility, aligning trades with broader index momentum using structured insights from Nifty Tip can help manage risk during sharp intraday swings.
Expected Passive Flow Impact
| Stock | Index Action | Estimated Flow |
|---|---|---|
| InterGlobe Aviation | Sensex Addition | Inflow of $314 million |
| Tata Motors PV | Sensex Deletion | Outflow of $190 million |
| Siemens Energy | FTSE Inclusion | Inflow of $147 million |
| HDB Financial | FTSE Inclusion | Inflow of $61 million |
| AB Lifestyle | FTSE All Cap Inclusion | Inflow of $13 million |
| Ather Energy | FTSE All Cap Inclusion | Inflow of $9 million |
The most significant impact is expected in InterGlobe Aviation, where sizeable inflows could support volumes and near-term price strength. Conversely, Tata Motors PV may remain under pressure due to passive selling linked to its removal.

Strengths
🔹 Large passive inflows into select stocks. 🔹 Improved liquidity and visibility post inclusion. |
Weaknesses
🔹 Flow-driven volatility unrelated to fundamentals. 🔹 Short-term pressure on deleted stocks. |
Index rebalancing days often see exaggerated intraday moves, followed by stabilisation once flows are absorbed. Traders should therefore differentiate between temporary flow impact and long-term investment merit.
|
Opportunities
🔹 Short-term momentum trades in index additions. 🔹 Post-event mean reversion setups. |
Threats
🔹 Sharp reversals once rebalancing flows end. 🔹 Liquidity-driven whipsaws. |
For broader indices, the impact of rebalancing is usually neutral, but individual stocks may experience significant temporary dislocations that active traders look to exploit.
Market View and Trading Approach
Investors should view index rebalancing as a technical event rather than a fundamental trigger. While additions may see short-term support, sustainable trends depend on earnings visibility and business outlook. Traders managing index exposure during such sessions may complement stock-specific strategies using insights from BankNifty Tip to maintain broader market alignment.
Investor Takeaway: Derivative Pro & Nifty Expert Gulshan Khera, CFP® notes that index rebalancing creates predictable but temporary price distortions. Investors should avoid chasing moves driven purely by flows and instead focus on post-rebalancing stability.
