Mirroring mixed cues from the Asian markets, the Sensex today opened flat at 13,930. The index moved sideways for the first hour but failed to retain its firmness and slipped to a low of 13,519, down 685 points.
Selling was witnessed in the Sensex after the European markets opened on a lower note. Heavy profit booking took place in the market before the expiry of the F&O dragged the index into the negative terrain.
The Sensex ended (provisonal) 321 points down at 13,591.
