Extending yesterday's sharp losses, the Sensex slumped about 108 points to 27,719.81 today as the October derivatives series began on a subdued note mirroring a weak trend in the global market.
The 30-share Sensex fell 107.72 points, or 0.39%, to 27,717.81. It had plunged 465 points in the previous session after India's surgical strikes on terror launch pads along the LoC on Wednesday night.
Consumer durables, FMCG, metal and capital goods stocks were trading in the negative zone, down by up to 0.37%.
The NSE Nifty offered a similar picture, which was down 36.05 points, or 0.41% at 8,555.20.
Brokers said continued selling in view of geo-political tension after India went ahead with surgical strikes on terror base across LoC on Wednesday night mainly dampened sentiment.
The selling came in the face of the beginning of October futures and options series in the derivatives segment, they said.
What unnerved the market further was muted Asian shares tracking overnight sell-off in New York after worries about the future of German banking giant Deutsche Bank lingered.
Hong Kong's Hang Seng was down 1.36% while Japan's Nikkei shed 1.55% in early session today.
The US Dow Jones Industrial Average ended 1.07% lower in yesterday's trade.
