The negative sentiments prevailing across the globe indicate pressure at the opening as global growth concerns came to haunt markets after the European Central Bank (ECB) slashed growth forecast. At the time of writing, SGX Nifty was trading at 11,068, down by 0.18 per cent. For Nifty, the zone of 10,980-11,000 is going to act as a crucial support, while on the upside, only a move above the February 7 high of 11,118 could provide a fresh impetus.
