The 30-share BSE index, which had rebounded 178.30 points in the previous session on Friday after the Economic Survey projected 7-7.75 per cent growth for 2016-17, tripped 58.60 points, or 0.25 per cent, to 23,095.70.
Similarly, the 50-share NSE Nifty was trading lower by 23.60 points, or 0.33 per cent, to 7,006.15.
Brokers said off-loading of bets by retail investors, continued foreign outflows ahead of the Budget and a mixed trend at other Asian bourses dampened sentiment here.
Japan's Nikkei was up 0.41 per cent while Hong Kong's Hang Seng shed 0.91 per cent in early trade today. The Shanghai Composite index fell 2.98 per cent.
