"...Investors should wait and watch the unfolding situation before making any major commitments. Buying should be confined to stocks/ segments which are fairly valued or have good earnings visibility," said V.K. Vijayakumar, Chief Investment Strategist at Geojit Financial Services.

"IT, though highly valued, is a sector whose prospects are steadily improving. There are instances of promoters buying stocks of IT companies. This is an indication of better-than-expected results from the sector. Investors can use sharp market corrections to slowly accumulate high quality stocks in IT."
