Mumbai, Sept. 24 -- Domestic equities extended their losing streak for the fourth straight session on Wednesday, with the Nifty slipping below the 25,100 mark as weakness in private banks, auto and IT stocks dragged the benchmarks lower. Investor sentiment remained fragile amid worries over changes in U.S. H-1B visa rules and persistent foreign fund outflows, which overshadowed hopes of a festive-season boost to consumption. Profit booking has also set in post-GST reforms as traders recalibrate valuations ahead of Q2 earnings.

The S&P BSE Sensex declined 386.47 points or 0.47% to 81,715.63. The Nifty 50 index lost 112.60 points or 0.45% to 25,056.90. In four sessions, the Sensex has slumped 1.56% and the Nifty has declined 1.44%.
