HISTORY repeated itself on The Stock Exchange, Mumbai (BSE) when the Sensex fell by over 160 points in one trading session last week. On Monday, October 7,when the index closed at 3,002.86, it had lost 251.87 points over a single week. While technical analysts are calling it the nadir of the fourth cyclical consolidation phase that began in April 1992, the last couple of months have evidently speeded up the slide. Since July the Sensex has actually fallen by over 800 points, thanks substantially to the ’97 Budget.
