MUMBAI The BSE Sensex fell on Thursday, led by ICICI Bank which was hit by profit-taking after beating earnings forecasts, while the expiry of January derivatives kept trading volatile towards the end of the session.
The BSE index added 2.4 percent in January to post its third-straight monthly gain and its longest winning streak since gaining for four consecutive months from June to September in 2010.
The gains were sparked by strong continued foreign net inflows, which reached 208.1 billion rupees as of January 30.
Analysts attribute January's gains to the government's efforts at additional fiscal reforms, but shares have fallen 1.04 percent since the central bank disappointed on Tuesday with a cautious stance on interest rates despite cutting them for the first time in nine months.
The outlook for stocks largely depends upon how the government handles its current account deficit and how the budget pans out.
"Next month will be critical from the Indian budget point of view, so that will occupy most of the mind space of traders and investors," said Jagannadham Thunuguntla, head of research, SMC Investments and Advisors Ltd.
"RBI will watch the budget data carefully and the impact it will have on inflation and rupee movement and take further decisions depending on that."
The benchmark BSE Sensex fell 0.55 percent, or 110.02 points, to end at 19,894.98, a shade below the psychologically important 20,000 mark.
The broader Nifty fell 0.35 percent, or 21 points, to end at 6034.75 on the last day of derivatives expiry.
January derivatives expired on Thursday. The last day of these contracts can typically lead to volatility in cash markets, especially towards the end of the session.
