Sensex, Nifty Suffer Biggest Weekly Fall in Over a Year

Introduction: A Week of Sharp Declines

The Indian stock market concluded the week ending March 6, 2026, with its most significant weekly loss in over a year. Escalating geopolitical tensions in West Asia and widespread selling pressure across most sectors pushed the benchmark indices, BSE Sensex and NSE Nifty 50, down by approximately 3% each. This sharp correction snapped a two-week gaining streak and erased significant investor wealth, signaling a shift in market sentiment from cautious optimism to risk aversion.

Market Performance in Numbers

The week's trading sessions were marked by consistent downward pressure, culminating in a steep fall on Friday. The BSE Sensex closed the week at 78,919, shedding 1,097 points on the final day alone. Similarly, the NSE Nifty 50 fell 315 points on Friday to settle at 24,450, dipping below the psychologically important 24,500 level. The broad-based nature of the sell-off was evident as the market capitalisation of BSE-listed companies declined by over ₹15 lakh crore during the week, reflecting the extent of the investor wealth erosion.

Financials and Realty Lead the Fall

The financial sector was the primary driver of the market's decline. The Nifty Bank index recorded its steepest weekly fall in 14 months, dragged down by heavyweights like HDFC Bank, ICICI Bank, Axis Bank, and State Bank of India. The Nifty PSU Bank index was hit even harder, plummeting by more than 6%, its largest weekly drop in a year. This sharp correction in banking stocks reflected concerns over macroeconomic headwinds and sustained selling by foreign institutional investors.

Alongside financials, the realty sector faced intense selling pressure. The Nifty Realty index was among the worst performers, with stocks like Godrej Properties, Lodha (Macrotech Developers), and Brigade Enterprises experiencing significant declines. The weakness in this sector was attributed to concerns over rising interest rates and potential regulatory changes impacting demand.

Broad-Based Sectoral Weakness

The negative sentiment was not confined to just two sectors. Nearly all sectoral indices ended the week in the red. The Nifty Oil & Gas, Metal, and Auto indices also registered declines of over 2.5%. Out of the 50 stocks in the Nifty index, 42 delivered negative returns, with 21 of them falling between 4% and 9%. Key losers included IndiGo, Tata Motors, Jio Financial Services, and Larsen & Toubro. The broader market also suffered, with the Nifty Midcap 100 and Nifty Smallcap 100 indices falling 2.6% and 3.1%, respectively, underperforming the main benchmarks.

Defence Stocks: The Lone Bright Spot

In a market dominated by sellers, the defence sector stood out as a notable exception. The defence index gained nearly 6% during the week, driven by positive news flow and expectations of strong order pipelines. Stocks such as Hindustan Aeronautics Ltd (HAL) and Bharat Electronics Ltd were among the top gainers in the Sensex basket. DCX Systems rose 6% after securing a ₹68 crore order from HAL, while Mazagon Dock Shipbuilders extended its gains, rising over 15% in just two sessions on anticipation of major new contracts.

Market Breadth and Investor Sentiment

The overall health of the market was poor, as indicated by the negative market breadth. The advance-decline ratio on the NSE stood at 2:3, clearly favouring sellers. This indicates that the selling was not limited to large-cap stocks but was widespread across the market. The sustained sell-off, coupled with tepid earnings from some heavyweight companies, has created a cautious atmosphere among investors, who are now closely monitoring global cues and domestic economic data for future direction.

Conclusion and Outlook

The week's performance marks a significant reversal from the previous positive trend, highlighting the market's vulnerability to global shocks and sector-specific pressures. The sharp correction led by the financial and realty sectors underscores investor concerns about the near-term economic outlook. While defence stocks provided a pocket of resilience, the broader market sentiment remains weak. Moving forward, investors will likely remain cautious, focusing on upcoming corporate earnings and developments in global geopolitics to gauge the market's next move.
