**

Market Snapshot

The Indian stock market witnessed a choppy trading session on August 04, 2026, as the initial euphoria from Monday’s rally faded. The Nifty 50 declined by 159.40 points, or 0.64%, to settle at 24,614.90. The BSE Sensex followed suit, dropping 210.08 points, or 0.27%, to close at 78,428.95. The divergence between the two indices, which was highly pronounced on Monday, began to narrow as the market adjusted to the National Stock Exchange's (NSE) new Closing Auction Session (CAS) framework. The India VIX, a measure of market volatility, rose 2.2% to end at 12.2 points.

Institutional Flows: Cash Market

Provisional data for August 04, 2026, indicated a shift in institutional behavior as foreign investors turned cautious after the previous session's sharp spikes.

• Foreign Institutional Investors (FIIs): Net sellers of equities worth ₹1,140.50 crore.
• Domestic Institutional Investors (DIIs): Continued to provide a cushion to the market, recording a net purchase of ₹3,159.24 crore.

This follows Monday’s activity where both FIIs and DIIs were net buyers, injecting ₹922.26 crore and ₹1,571.18 crore respectively into the cash segment.

Derivatives Market Activity

Activity in the derivatives segment reflected high-stakes positioning ahead of the weekly Nifty expiry.

• FII Index Futures: Recorded a significant change with 1,784 new long contracts and a reduction of 20,513 short contracts, suggesting some short-covering at lower levels.
• Open Interest (OI): The 24,600 strike for both calls and puts held the highest open interest, indicating a "straddle" like indecision among traders regarding the immediate direction.
• FII Index Options: Witnessed substantial activity with over 101,331 put contracts being shortened, indicating that institutional players are looking for a floor near the 24,400–24,500 zone.

Key Drivers and Outlook

The primary driver for Tuesday’s decline was the "normalization" of the Nifty 50. Analysts noted that Monday’s 390-point spurt was an aberration caused by the first day of the new CAS mechanism, which uses a dedicated auction to determine closing prices rather than the traditional volume-weighted average.

• LIC Sell-off: Shares of Life Insurance Corporation (LIC) tumbled 8.68% to close at ₹391.30 following reports that the government plans to sell up to a 6.5% stake in the insurer at a floor price of ₹382 per share.
• RBI Policy: The market remained on edge as the RBI's Monetary Policy Committee (MPC) is scheduled to announce its decision on Wednesday. While a status quo on rates is expected, the commentary on inflation and liquidity will be crucial.
• Crude Oil Pressures: Brent crude prices rose to $84.91 per barrel, adding to concerns regarding imported inflation and the fiscal deficit.
• Sectoral Performance: Real Estate was the worst hit, with the Nifty Realty index sliding over 2%. IT and Financials also dragged, while the Metal sector remained the sole outlier, closing in the green led by Hindalco (+2.27%).

Going forward, the 24,400 level is expected to act as a vital support for the Nifty, while 24,750 remains a formidable resistance.
