Indian benchmark equity indices ended on a mixed, range-bound note on Thursday, August 6, 2026. On a day marked by weekly derivatives contract expiry, markets traded in a narrow corridor before institutional un-crossing during the Closing Auction Session (CAS) finalized the closing bell numbers.
The Nifty 50 settled virtually flat to slightly positive at 24,636.00 (+11.35 pts / +0.05%), after oscillating between an intraday high of 24,677.05 and a low of 24,604.15. Meanwhile, the BSE Sensex posted significantly stronger gains, surging +373.76 pts (+0.48%) to close at 78,954.76, propelled by heavy weight buying in Reliance Industries and ICICI Bank. The Bank Nifty rebounded sharply from the previous session’s pauses, rising +323.70 pts (+0.56%) to settle at 58,063.65.

⚡ Four Days of CAS: Why Nifty and Sensex Are Diverging
Four trading sessions into the implementation of the NSE and BSE’s new Closing Auction Session (CAS) mechanism (operating daily between 15:15 PM and 15:30 PM), the structural divergence between the Sensex and Nifty performance has become a major talking point among Dalal Street institutional desks.
The Liquidity Disparity in the 3:15 PM Window
While both benchmark indices trade almost in lockstep during regular continuous trading hours (09:15 AM to 15:15 PM), the 15-minute un-crossing window reveals key differences:
- Institutional Concentration: Index arbitrageurs, foreign portfolio investors (FPIs), and domestic mutual funds route the vast majority of their Market-on-Close (MOC) basket orders through Nifty 50 constituents. This dense liquidity absorbs large block volumes smoothly, resulting in an exact, volume-weighted closing average (settling Nifty at 24,636.00).
- BSE Liquidity Thresholds: The BSE CAS window experiences relatively lower depth in certain overlapping constituents. On weekly derivatives expiry days (such as today), concentrated buying in heavyweights like Reliance (+3.43%) and State Bank of India (+3.02%) creates a disproportionate upward push on the Sensex, causing a +0.48% leap compared to Nifty’s steady +0.05% finish.
- VWAP Normalization: For traders, understanding that the final 15-minute CAS window calculates the Volume-Weighted Average Price (VWAP) is vital to preventing slippage when executing algorithmic or end-of-day portfolio rebalancing strategies.
🌎 Global Cues Today: Crude Moderation & Diplomatic Talks
External macros provided a constructive backdrop for Indian equities today:
- Easing Crude Oil Prices: Brent crude futures stabilized under the $80 per barrel mark ($79.50/bbl). Markets reacted positively to diplomatic negotiations aimed at defusing Middle East shipping bottlenecks, providing relief to India’s import bill and inflation trajectory.
- Asian & US Markets: Asian equities traded with a mixed bias as Japan’s Nikkei consolidated, while US equity futures held flat ahead of upcoming non-farm payroll and labor metrics.
- Currency Dynamics: The Indian Rupee saw modest weakness, closing near 95.24 against the US Dollar, largely due to routine corporate dollar demand.
🇮🇳 Domestic Triggers & Sectoral Performance
Sectoral trends showed a clear split between heavy engineering/energy names and utility laggards:
- Energy & Banking Lead Gains: Reliance Industries emerged as the single largest index contributor, rising +3.43%, followed by strong buying in State Bank of India (+3.02%), Bharat Electronics (+2.56%), and ICICI Bank (+2.28%).
- Q1 Earnings Realities: Earnings reports dictated sharp stock-specific moves. Defence major Hindustan Aeronautics (HAL) surged over +5.9% on strong order intake visibility, whereas Power Grid Corporation fell -3.99% following a modest year-on-year drop in consolidated quarterly net profit.
- July Auto Sales Strength: Industry data released today showed total Indian auto retail sales for July 2026 jumped +26% YoY to 25.91 lakh units, pointing to steady rural and urban consumption recovery.

Support 2: 24,450 (Crucial Support Zone)
Strategic Trading Plan:
- Bullish Trigger: A decisive breakout above 24,720 on an hourly closing basis will trigger short covering toward 24,800 and 25,000.
- Support Base: The 24,550 – 24,500 band continues to act as a resilient demand zone. As long as Nifty holds above 24,450, the primary broader structure remains buy-on-dips.
