The BSE Sensex today dived almost 510 points -- its biggest single-day fall since February 6 -- to close at 33,176 due to a major sell-off amid global trade worries and political concerns after the TDP quit the NDA and moved a no-confidence notice against the government. Other Asian markets were also in the negative zone as investors fret over the prospect of a global trade war, accelerating selling pressure on the domestic bourses, brokers said.


For the third straight week stocks ended in the red with the flagship Sensex recording a weekly fall of 131.14 points, or 0.39 per cent, and the NSE Nifty losing 31.70 points, or 0.30 per cent.


Sentiment suffered a setback following fresh development on the political front after a key NDA ally, TDP, decided to quit the alliance and moved a no-confidence motion notice against the government, accelerating the selling pace by participants, brokers said. -- PTI
