Mumbai, July 09: The benchmark BSE Sensex cracked the 28,000-mark by tumbling 292 points in early trade today on across-the-board selling by participants, tracking more heavy losses in Shanghai and on fears about Greece’s future in the Eurozone.

The 30-share index dipped below the 28,000-mark by diving 291.65 points or 1.04 per cent to 27,880.04.

The gauge lost 37.07 points in its last choppy session.

All the sectoral indices, led by metal, banking and auto were trading in the negative terrain, falling by up to 1.60 per cent.

On similar lines, the National Stock Exchange index Nifty slipped below the 8,500-mark by falling 93.30 points or 1.09 per cent to 8,417.50.

Brokers said sentiments on the domestic bourses dampened following a rout in other Asian markets with nearly 7 per cent crash in Shanghai and on fears about Greece’s future in the eurozone, triggering widespread selling.

Among other Asian markets, the Shanghai Composite Index slumped 6.72 per cent, Hong Kong’s Hang Seng index plunged 4.45 per cent, while Japan’s Nikkei index was trading 1.52 per cent down in early trade today.

The US Dow Jones Industrial Average, however, ended 0.53 per cent higher in yesterday’s trade.

The rupee weakened by 13 paise to 63.59 against the US dollar in early trade today, extending losses for the second day, due to appreciation of the American unit against other currencies overseas amid Greece’s crisis.

Besides increased demand for the dollar from importers, a lower opening in the domestic equity market also weighed on the local currency, forex dealers said.

The rupee had slipped by 6 paise at 63.46 in yesterday’s trade due to fresh demand for the American currency from banks and importers amid strong overseas sentiments.

Meanwhile, the benchmark BSE Sensex dipped below the 28,000-mark by plunging 291.65 points or 1.04 per cent to 27,880.04 in early trade.
