Equity markets began on a positive note on Wednesday, as the Sensex and Nifty both gained on the back of fresh foreign fund inflows and a strong rally in US markets. However, concerns surrounding trade tensions and tariff threats from US President-elect Donald Trump led to increased volatility during the morning session.

The BSE benchmark Sensex surged by 166.1 points, reaching 80,170.16 in the early trade, while the NSE Nifty rose by 74.35 points to touch 24,268.85. However, both indices experienced fluctuations later, with the Sensex trading 60.26 points higher at 80,055.58 and the Nifty advancing by 16.55 points to 24,211.10 by midday.
