Share Market Today: Sensex, Nifty Extend Losses; Rs 1.89 Lakh Crore Wiped Out

Share Market Today: Sensex Plunges 346 Points as Year-End Volatility Wipes Out ₹2 Lakh Crore

The Indian equity markets faced a wave of selling pressure on Monday, December 29, 2025, marking a somber start to the final trading week of the year. In a session characterized by thin holiday volumes and cautious sentiment, the benchmark indices extended their losing streak for the third consecutive day. Investors saw nearly ₹2 lakh crore in paper wealth evaporate as the bears tightened their grip on Dalal Street.

Market Performance: A Sea of Red

The BSE Sensex plummeted 346 points, or 0.41%, to settle at 84,695.54. Similarly, the broader NSE Nifty 50 shed 100.2 points, or 0.38%, closing at 25,942.10. The decline was not restricted to the heavyweights; the “broader market” also felt the heat, indicating a widespread lack of buying conviction. The BSE Midcap Index slipped 0.4%, while the BSE Smallcap Index underperformed further, dropping 0.5%.

The persistent weakness over the last three sessions suggests that the year-end “Santa Claus rally” many hoped for has been sidelined by macroeconomic concerns and technical profit-booking.

Why Did the Market Fall? Key Drivers

Several factors converged to dampen investor spirits on Monday. While the final week of December is typically known for low institutional activity, the following triggers played a crucial role:

1. Persistent FII Outflows: Foreign Institutional Investors (FIIs) continued their selling spree, a trend that has plagued the Indian markets throughout the final quarter. The lack of fresh capital inflows from overseas desks left the market vulnerable to domestic selling pressure.

2. Crude Oil Surge: A sudden uptick in global crude oil prices acted as a major headwind. For an oil-import-dependent economy like India, rising crude prices raise fears of imported inflation and a widening current account deficit, directly impacting sectors like paints, aviation, and logistics.

3. Thin Trading Volumes: With many global fund managers on year-end breaks, trading volumes remained significantly lower than average. In such “thin” markets, even moderate sell orders can cause disproportionately large price swings.

4. Lack of Global Cues: With major Western markets either closed or operating on reduced holiday schedules, there was no positive lead from the US or European markets to bolster local sentiment.

Sectoral Heatmap: Bearish Grip Tightens

Almost all major sectoral indices ended the day in the red, reflecting the broad-based nature of the sell-off. The Media sector was the lone warrior, managing to close with marginal gains, while other sectors suffered:

• IT & Pharma: Generally considered defensive, these sectors saw significant profit-taking as investors moved toward cash.

• Auto & Power: These sectors were hit by concerns over rising input costs (linked to energy prices) and a cautious outlook for the coming quarter.

• Realty: Higher interest rate anxieties continued to weigh on the real estate pack, leading to a decline of nearly 0.9% in the sectoral index.

Investor Wealth Erased: The ₹1.89 Lakh Crore Hit

The carnage on the trading floor translated into a significant dent in investor portfolios. The total market capitalization of all BSE-listed companies dropped from ₹473.97 lakh crore in the previous session to ₹472.09 lakh crore today.

This represents a loss of approximately ₹1.89 lakh crore in a single day. For retail investors, the three-day losing streak has been a stark reminder of market volatility, especially following the aggressive highs seen earlier in the year.

Top Gainers and Losers: Sensex Breakdown

Despite the overarching gloom, a handful of stocks managed to swim against the tide. Of the 30 stocks comprising the BSE Sensex, only 8 finished in green.

The Top 5 Gainers

1. Tata Steel: The standout performer, rising 1.83% on the back of positive demand outlooks for the next fiscal year.

2. NTPC: Gained 0.95%, benefiting from its status as a stable, dividend-yielding utility play.

3. Axis Bank: Showed resilience in the private banking space with a 0.65% rise.

4. Asian Paints: Despite oil concerns, it saw bottom-fishing, closing 0.42% higher.

5. Eternal: Managed to secure a 0.33% gain in a volatile session.

The Top 5 Losers

1. Adani Ports: Led the laggards with a sharp decline of 2.22%.

2. HCL Tech: Caught in the IT sell-off, dropping 1.86%.

3. Power Grid: Saw a reversal of recent gains, falling 1.54%.

4. Trent: The retail giant faced profit-booking, shedding 1.40%.

5. Bharat Electronics (BEL): Declined 1.26% as investors de-risked their defense holdings.

Market Breadth: Bears Outnumber Bulls

The market breadth remained heavily skewed in favor of the sellers. Out of the 4,512 shares traded on the BSE today:

• 1,568 shares advanced (Gains)

• 2,748 shares declined (Losses)

• 196 shares remained unchanged

Interestingly, the market continues to show a “K-shaped” recovery in specific pockets. While 115 shares managed to touch new 52-week highs, reflecting strength in niche segments, a significant 195 shares hit new 52-week lows, signaling deep distress in specific small-cap and penny stock categories.

Outlook for the Week

As we head into the final three trading sessions of 2025, analysts expect the market to remain range-bound with a bearish bias. The primary focus will remain on the Nifty’s crucial support level at 25,800. If the index fails to hold this mark, further selling toward 25,500 could be triggered.

Investors are advised to maintain a cautious stance, focusing on high-quality blue-chip stocks with strong earnings visibility, rather than chasing momentum in the mid and small-cap space. With the new year on the horizon, the market’s trajectory will likely be dictated by the upcoming Q3 earnings season and the initial cues for the 2026 Union Budget.
