Sensex Surges 753 Points as US-Iran Peace Hopes Ignite Market Rally; DIIs Anchor Gains with ₹2,064 Cr Inflow

Market Snapshot

The Indian equity markets witnessed a robust broad-based rally on April 21, 2026, as benchmark indices surged nearly 1% to hit six-week highs. The BSE Sensex jumped 753.03 points, or 0.96%, to settle at 79,273.33, while the NSE Nifty 50 climbed 211.75 points, or 0.87%, to end at 24,576.60. Market volatility significantly eased, with the India VIX dropping 6.69% to 17.53, reflecting improved investor sentiment.

The day's performance was characterized by:

• A strong recovery in banking and FMCG heavyweights, with the Nifty Bank index outperforming the benchmarks to gain 1.39%.
• Nestle India emerged as the top Nifty gainer, surging over 8% following stellar Q4 results, followed by Hindustan Unilever and Trent.
• Market breadth remained firmly in favor of bulls, with over 2,000 stocks advancing on the NSE against 1,247 decliners.
• The total BSE market capitalization increased by approximately ₹3 lakh crore, reaching a near-record ₹469 lakh crore.

Institutional Flows: Cash Market

Provisional data for April 21, 2026, revealed a continued divergence between foreign and domestic institutional activity. Domestic Institutional Investors (DIIs) acted as the primary market stabilizers, offsetting persistent outflows from Foreign Institutional Investors (FIIs).

The provisional figures for the cash segment are as follows:

• Foreign Institutional Investors (FIIs): Net sellers of ₹1,770.66 crore, with gross purchases of ₹12,449.81 crore and gross sales of ₹14,220.47 crore.
• Domestic Institutional Investors (DIIs): Net buyers of ₹2,064.72 crore, with gross purchases of ₹17,252.89 crore and gross sales of ₹15,188.17 crore.

This marks a continuation of the trend seen throughout April, where DIIs have consistently absorbed FII selling pressure, providing a floor for the benchmark indices.

Derivatives Market Activity

The derivatives segment signaled a bullish bias as the Nifty Put-Call Ratio (PCR) hovered around 1.05. Institutional traders focused on heavy-duty financials and FMCG counters ahead of the monthly expiry.

Key highlights from the F&O segment include:

• Significant open interest (OI) buildup was observed in the 24,500 and 24,600 Nifty Call options, suggesting these will act as immediate resistance levels.
• Banking stocks saw a healthy mix of long buildup and short covering, particularly in ICICI Bank and Axis Bank, following positive brokerage commentary.
• The sharp decline in India VIX suggests that the "fear factor" regarding the West Asia conflict is temporarily receding, allowing traders to take larger directional bets.

Key Drivers and Outlook

The primary catalyst for Tuesday's rally was the reported progress in peace negotiations between the United States and Iran in Islamabad. With the current ceasefire deadline approaching, investors are pricing in a de-escalation of tensions, which has directly led to a retreat in Brent crude prices to the $94–$95 per barrel range.

Looking ahead, the market outlook remains cautiously optimistic:

• Earnings Momentum: Investors will closely monitor Q4 results from major firms like Trent, Tech Mahindra, and SBI Life, scheduled for release on April 22.
• Global Cues: Any further updates from the US-Iran talks will remain the most critical trigger for global and domestic sentiment.
• Technical Levels: For Nifty, the 24,500 mark has now turned from resistance to immediate support, with the next major target seen at 24,750. On the downside, 24,350 remains a crucial support zone.
