21 September, 2026 Stock Market Updates: Sensex adds 240 points, Nifty holds 23,300, UltraTech top gainer

The Indian stock market ended the day with a modest upward trend on 21 September 2026. The benchmark indices, Sensex and Nifty, both posted gains, with the Sensex climbing by 240 points. The Nifty 50 index held steady above the 23,300 mark, indicating a stable market sentiment. Among individual stocks, UltraTech Cement emerged as the top gainer, leading the rally in the broader market.
For investors, this session highlights a market in consolidation. The Sensex's gain of 240 points suggests that buying interest is present, but the Nifty's ability to hold above 23,300 is a key technical level to watch. A strong hold here could signal continued stability, while a break below might indicate a pause in the rally. Investors should monitor the breadth of the market to gauge if the gains are broad-based or driven by a few large stocks like UltraTech.
