Indian equity markets concluded lower on Monday, January 19, 2026, with key benchmark indices BSE Sensex and NSE Nifty50 registering declines. The Sensex fell 324.17 points, or 0.39%, to settle at 83,246.18, while the Nifty50 dipped 108.85 points, or 0.42%, ending at 25,585.50. The market witnessed an intraday tumble, with the Sensex dropping as much as 672 points and the Nifty50 touching an intraday low of 25,494.35. This downturn was attributed to a combination of factors including stock-specific selling pressure, disappointing third-quarter earnings from several heavyweight companies, and a cautious global sentiment. Among individual stocks, Wipro experienced a significant plunge, sliding over 8% during the trading session and settling at Rs 245.50. This sharp decline was primarily driven by the company's weak outlook for the fourth quarter and a 7% decrease in its consolidated net profit for Q3 FY26, impacted by one-off restructuring charges and new labor code implementations. Reliance Industries (RIL) also faced considerable pressure, with its shares dropping around 3% to Rs 1,414.50, after investors reacted negatively to its mixed December quarter results that fell short of market expectations. In contrast, InterGlobe Aviation, the operator of IndiGo, emerged as a top gainer, surging by over 4% to Rs 4,941.50. This rise occurred despite the Directorate General of Civil Aviation (DGCA) imposing a substantial penalty of ₹22.20 crore on the airline for widespread flight disruptions in December and regulatory non-compliance. The broader market sentiment was further dampened by renewed global trade tensions. US President Donald Trump threatened to impose new tariffs on eight European nations over their opposition to his bid to acquire Greenland, sparking fears of an escalating US-EU trade dispute. This development led to a broad risk-off mood across international equity markets and encouraged a rotation towards safe-haven assets. Persistent outflows from Foreign Institutional Investors (FIIs) from Indian equities also contributed to investor jitters.
