Weak IIP numbers, and rising crude prices, which may result in a fiscal strain on the economy, exerted pressure on the bourses, as the Sensex and Nifty, both, ended almost at the day's lows of 19,263 down 189 points and 5,786 off 56 points respectively.
Oil and gas exploration major Reliance Industries, along with HDFC, HDFC Bank and Tata Motors dragged the Sensex down on Monday.
The markets, which opened in the red on Monday, gained marginally during the initial hour of trade.
The Sensex touched its peak of 19,426, but, rampant selling in auto and realty stocks, along with slipping heavyweights, saw the bourses dip into the red. Negative movements continue ever since.
The broader markets also ended in the red, after a rally seen in the sectors last week.
The Mid-cap index was at 7,124 while the Small-cap index was at 8,710, both off 0.7% each.
Sunteck Realty was the top loser on the mid-cap index, down 10% at Rs 344. S Kumar Nation at Rs 64 and JM Financial at Rs 27, both down 6%,
