Stock markets had opened on a strong note with the 30-scrip Sensex touching a high of 25,548.33 points in early trade on better-than-expected results from IT major Infosys.
However, lingering concerns over Eurozone debt resurfaced as reports said Portugal's biggest listed bank missed debt payments, triggering a sell-off, brokers said.
As a result, the BSE Sensex dipped below the 25,000 mark to touch day's low of 24,978.33 on across-the-board profit booking by participants. The barometer closed with a hefty fall of 348.40 points, or 1.37 per cent, at 25,024.35. The gauge has now shed 1,075.73 points in four straight sessions.
Strong selling pressure was seen in sectors like realty, oil & gas, power, capital goods and PSU stocks that had outperformed in the run up to the Union Budget, brokers said.
