its a great article which tell us about history of sensex but eventually dates from 3000, Feb 29, 1992 to 6000, Feb 11, 2000 are wrong which contradics the above statement that sensex crossed 3000 mark on May 6, 2003. Moreover, from 3000 to 4000 it took only one month as displayed.
This is a great article, now how about a graph including the PE's and dates , where, when u move ur mouse over it , the corresponding dates, sensex and PE values get reflected in a column below.
