"We believe this is part of the normal correction process and the medium-to-long term uptrend remains intact. We have always maintained that any knee-jerk short-term correction in markets as response to global events should be looked at as an opportunity to accumulate quality stocks", says Gaurav Dua, Head-Research, Sharekhan.
BSE mid and small cap indices also slipped. The mid-cap index underperformed and was down 1%.
Asian markets ended in the green. Seoul Composite added 0.7% to 1,940. Shanghai Composite advanced 1%. Jakarta was up 1% at 3,725.
