The benchmark stock index slid to a two- month low, led by industrials and metal companies, as the monthly derivative contracts expired and the US Federal Reserve signaled it's prepared to raise interest rates in December.
Bharat Heavy Electricals, the largest power-equipment producer, tumbled the most in almost two months, while Coal India, the world's biggest miner of the fuel, capped its biggest four-day loss in a month. Axis Bank and State Bank of India paced losses among lenders. Dr Reddy's Lab climbed for the first time in three days before its results, while NTPC slid for a third day even as the biggest power generator posted results that beat forecasts.
The S&P BSE Sensex slid 0.8 per cent to 26,838.14 at the close in Mumbai in a fourth day of drop, the longest stretch of losses since August. The gauge has climbed 2.6 per cent in October, on course for its best month since May, as overseas funds returned to emerging markets amid signals the Fed will delay raising borrowing costs until 2016. Those gains may evaporate if the inflows reverse after the US central bank closes an unprecedented era of near-zero rates in December and Indian company earnings take longer to recover.
"Looks like a December rate hike by the US Fed is pretty much on the cards," Vaibhav Sanghavi, managing director at Ambit Investment Advisors Pvt in Mumbai, said by phone. "Earnings have been a mixed bag so far, some good, some not so good."
