Here are some numbers from 1990 onward: Total of 75 days of over 4% gains on the NDX. The following day breaks down like this: 1990-2000 13 up days, average gain 1.56% 12 down days, average loss -1.674% 2000 to present 23 up days, average gain 2.54% 27 down days, average loss -2.38% The last 5 days following a 4% up day have been up days. Funny enough, last July 5th we were up 4.14% and on July 8th, we were down 3.51%. I hope history repeats itself.
