India’s benchmark Nifty 50 increased 3.45% in the past week, closing the day at 25693.7 points on Friday (February 6, 2026), as markets calmed down from sudden surprises like the STT hike, the U.S.-India trade deal and the Anthropic-led AI scare.

The index opened at 25333.75 points on February 1, 2026 and dropped to 24571.75 points, the week’s low, on the very day before closing slightly up at 24825.45 points. Following this, the index moved to the week’s high of 26341.2 points on February 3, as clarity regarding the U.S. tariffs emerged.

The optimism, however, slowed as more details regarding the terms are awaited. The very next day, Anthropics’ new legal tool feature on the Claude AI chatbot spooked U.S. IT stocks like Alphabet Inc. and Microsoft Corporation, among others, spurring a sell-off in Indian IT stocks, with the Nifty IT index dipping more than 5% in a single session. The tech index continued its losses on the last day of the week, falling about 1%.

While a variety of news kept the markets volatile on a daily basis, the India VIX index, which measures the markets’ volatility, experienced the calmest session in three weeks. The India VIX index for the week was down 20% to 12.0125 points on Friday, marking the second consecutive week of reducing volatility.

“In the last week, the benchmark indices witnessed a sharp bounce back. The Nifty ended 3.40% higher, while the Sensex was up over 2,850 points. Among sectors, the Capital Market and Reality indices outperformed. The Capital Market index was up by 7.45%, and the Reality index rallied by 7.70%, whereas the IT index lost the most, shedding over 7%,” said Amol Athawale, Vice President of Technical Research at Kotak Securities.
