Equity benchmark indices Sensex and Nifty buckled under heavy selling pressure on Thursday as investors pared exposure to bellwether stocks HDFC Bank, M&M, Nestle and Reliance Industries amid a mixed trend in global markets. Besides, the interest rate hike by the US Fed failed to boost sentiments in the domestic market, which saw a steep decline led by banking and auto stocks, traders said. After opening with gains of over 125 points, BSE Sensex plunged 440.38 points or 0.66 per cent to settle at 66,266.82, while Nifty declined 118.40 points or 0.60 per cent to close at 19,659.90.
