Stocks reeled under huge losses on Thursday as benchmark Sensex plunged sharply by over 465 points, the biggest single-day fall in three months, after India carried out "surgical strikes" last night on terror launchpads across LoC.
The rupee too was in the line of fire, down 49 paise (intra-day) against the US dollar, to trade at 66.95.
World markets, however, cheered the surprise deal cut by OPEC to slash oil output for the first time in eight years.
The stocks started off higher extending yesterday's recovery, but suffered a jolt after announcement that India conducted surgical strikes last night on terror pads across the Line of Control.
The Sensex hit a high of 28,475.57, in sync with a firm Asian trend after a surprise decision by OPEC to cut oil output to push up prices.
But the Army's announcement triggered all-round selling, sending the Sensex into a tizzy, which broke below the key 28,000-mark. It settled at 27,827.53, down 465.28 points, or 1.64 per cent -- its biggest single-day fall since June 24 and weakest closing since August 26 when it closed at 27,782.25.
The gauge had recovered 69.11 points in yesterday's trade.
The 50-share NSE Nifty, which cracked below 8,600-level to hit a low of 8,558.25 during the session, managed to recover part of the initial losses and settled down 153.90 points, or 1.76 per cent, at 8,591.25.
Mood turned cautious after the Army said the surgical offensive last night came on "very specific and credible information" about Pakistan-based terrorists being pushed into Indian territory for carrying out strikes in Jammu and Kashmir and various cities in India.
Expiry of September series contracts in the derivatives segment influenced trading sentiment, brokers said.
The red mark was near complete as 29 of 30 Sensex stocks slumped. Adani Ports, Sun Pharma, ICICI Bank, GAIL, Tata Steel, Lupin, Tata Motors and SBI crashed by up to 5.01 per cent. TCS manged to close in the green, up 0.46 per cent.
Among BSE sectoral indices, realty suffered the most by 6.31 per cent, followed by power (4.11 per cent), healthcare (3.26 per cent), metal (3.17 per cent), infrastructure (3.15 per cent), consumer durables (2.84 per cent), PSU (2.82 per cent) and capital goods (2.50 per cent).
Broader markets also performed weak, with the BSE small-cap index falling 4.02 per cent and mid-cap 3.60 per cent.
Foreign portfolio investors (FPIs) net bought shares worth Rs 73.83 crore yesterday, as per provisional data.
Japan's Nikkei rose 1.39 per cent and Hong Kong's Hang Seng 0.51 per cent. Shanghai Composite Index ended 0.36 per cent higher.
Europe was also in the green as London-based FTSE index rose 1.09 per cent, Paris CAC 30 1.36 per cent and Frankfurt's DAX 0.93 per cent in their early trade.
