Stock market news, Dec. 1 -- The benchmark stock indices, Sensex and Nifty 50, finished nearly unchanged on Friday in a session marked by high volatility as investors remained cautious ahead of important macroeconomic data releases after the market closed. After two consecutive days of gains, the 30-share Sensex dipped by 13.71 points or 0.02% to close at 85,706.67. Throughout the day, it reached a peak of 85,969.89 and a trough of 85,577.82, swinging by 392.07 points.

The Nifty 50 fell by 12.60 points or 0.05% to settle at 26,202.95. Earlier, both key indices had surged to record levels during intra-day trading on Thursday but ultimately closed nearly flat due to investors cashing in on profits during the latter part of the session.
