Good point on the std. dev. I had to pull out the book to recall how to figure them, <g> but here they are: Since sample size, n < 20 , a range estimate calculation is used. Calculations of the daily std. dev's produce the following: MON avg. = -2.1, s.d. = 9.3 TUE avg. = -9.1, s.d. = 24.6 WED avg. = +7.5, s.d. = 13.0 THR avg. = +11.0, s.d. = 15.0 FRI avg. = +12.0, s.d. = 26.1 The high std. dev. values show how volatile the market has been over the last 13 weeks, particularly on tuesdays and fridays.
