Mumbai, Nov 30 (IANS): Key Indian equity indices closed on a subdued note on Thursday, with the BSE sensex falling over 400 points and the NSE Nifty dropping almost 130 points.

According to market observers, investors traded with caution on futures and options (F&O) expiry day, as well as ahead of the second quarter GDP data announcement later in the day.

Heavy selling pressure in banking, auto and metal stocks coupled with negative Asian markets added to the downward slide.

The Sensex touched a high of 33,576.20 points and a low of 33,108.72 during intra-day trade.
