Although the market close was positive, brokers expect a correction just round the corner, which may come anytime.

``Wednesday's marginally higher close against a 65-point drop in the tech-heavy Nasdaq on Tuesday night indicates that the market is just taking time to go into a correction,'' said a dealer with a domestic broking house. ``And Wednesday's positive close was mainly on the back of a massive rally in Satyam,'' he added.

Other than Infosys, the other index-heavyweight Hindustan Lever also closed lower at Rs 2579, down Rs 15.50 over its previous close. According to market players, it was mainly selling by two leading FIIs along with a leading domestic mutual fund which contributed to the fall in Infosys.

Wednesday's trading was marked by extreme volatility in a number of technlogy stocks, led by the operators' favourite - Himachal Futuristic. Other stocks which also witnessed substantial volatility during the day were SSI, Silverline and Zee.
