Bears roared back into action on Dalal Street after a long time. The much-needed correction materialised on Monday with investors unloading stocks across the board, sending the benchmark Sensex crashing by 148 points. The market is poised for further fall as more investors are getting ready to exit. Fears of a slowdown in inflows from US hedge funds triggered profit-taking. A fall in Indian ADRs on Friday, weakness in other world markets and a fresh upward spike in global crude oil prices too dampened the sentiment. The Sensex plunged 147.83 points or 1.9 per cent to settle at 7,606.17 in the selling avalanche. The S&P CNX Nifty lost 36.80 points or 1.5 per cent to settle at 2,324.40. Monday’s correction followed a steep rise in the market in the last few weeks. In what was one of the steepest rallies, Sensex jumped nearly 500 points in mere nine trading sessions between July 22 and August 4. Heavy inflows from FIIs were instrumental in sending the stocks to dizzy heights. ‘‘The magnitude of the fall indicates huge selling by hedge funds. The market was overheated in the last few days. There was no reason for the sustained rally in the last one month. I have been cautioning investors about the unreasonable price levels in the last few days,’’ said NSE dealer Pratip Bhavnani. Correction was overdue
