Equity benchmark indices Sensex and Nifty buckled under heavy selling pressure to sink below record high levels on Wednesday, tracking deep losses in metal, auto and IT stocks amid widespread profit booking after recent gains.
Rising uncertainty over interest rate cut by the US Federal Reserve also added to the weak trend in domestic equities, traders said.
The 30-share BSE Sensex opened 129.72 points higher to hit a fresh all-time high of 80,481.36.
However, the index soon tumbled 915.88 points or 1.13 per cent to trade at 79,435.76.
It finally closed lower by 426.87 points or 0.53 per cent at 79,924.77.
The NSE Nifty also hit its record 24,461.05 in opening deals but pared all gains to decline 291.4 points or 1.19 per cent to 24,141.80 intra-day.
It dropped 108.75 points or 0.45 per cent to settle at 24,324.45.
In the Sensex pack, Mahindra & Mahindra tanked over 6 per cent after the company cut the prices of its SUV models to boost demand.
Mahindra & Mahindra said its XUV700's fully-loaded AX7 range now starts at Rs 19.49 lakh, a price cut of over Rs 2 lakh.
Tata Steel, Tata Consultancy Services, HCL Technologies, State Bank of India, JSW Steel, Tata Motors and Kotak Mahindra Bank were other losers.
