Stock Market Today, Jan. 29 -- Markets managed to end Tuesday's volatile trading session on a positive note. The benchmark Nifty 50 index ended at 22,957.25, up 0.56%, and the S&P BSE Sensex, at 75,901.41, also ended 0.71% higher. Bank Nifty rebounded 1.67% to end at 48,866.85, as Realty and Auto were also key gainers after RBI provided a liquidity boost. Energy and Pharma, however, still remained under pressure, and so did mid- and small-caps.

Support for Nifty is placed at 22786, while immediate resistance is seen at 23,137, followed by 23347, said Nandish Shah - Deputy Vice President, Prime Research at HDFC Securities
