The red line is the Nasdaq index overlaid on the chart with its now infamous peak in early 2000 (and before you ask, the timescale is 1:1 and has not been stretched or compressed in any way).The correlation between the two lines is 96.65%, according to the guy who sent me this last night (he sent it as an Excel file and the numbers do seem to check out correctly. FWIW I regenerated this chart to check them myself.).
