The benchmark indices NSE Nifty 50 and BSE Sensex 30 closed on a flat note but what grabbed attention are the Midcap and Smallcap stocks which saw strong buying sentiment prevailing throughout the day.

The broader indices remained under pressure throughout the day as investors chose to book profit ahead of the monthly expiry and uncertain global cues. NSE Nifty 50 index plunged 0.82 per cent to close below 18,200 level while Sensex tanked over 500 points.
