Slower growth in industrial output brought the fear element back for investors on Monday as both stock benchmarks lost nerve and ended with sizeable losses. The decline - close to 1 per cent for the Sensex and the Nifty-was all but pervasive across sectors. Caution ruled ahead of CPI inflation data slated for later in the day. The positive start soon gave way to nervousness as the BSE index cracked below 33,000, but finally ended at 33,033.56 - a three week low - down 281 points, or 0.84 per cent. The barometer rose a cumulative 95.75 points in the past two sessions. The NSE Nifty settled the day lower 96.80 points, or 0.94 per cent, at 10,224.95 after shuttling between 10,334.15 and 10,216.25 during the day.
