The Sensex and the Nifty saw wild swings on February 2, falling sharply from the day's high due to profit-booking by investors. Analysts expect markets to test higher levels in the days to come, as uncertainties surrounding budget and US Fed's rate meeting dissipate. The Sensex was off 900 points from the day's high of 73,089, while the Nifty lost 227 points after hitting an all-time.
