well, if you look at the chart, BRK.A has been climbing that whole time. someone less lazy than me could count up how many days it went up, and how many days it went down and give you a a good number. let's just say there are 100 down days, and 200 up days.
what are the chances of selecting 6 up days without replacement? 200/300 * 199/299 * 198/298 * 197/297 * 196/296 * 195/295 ~ 0.085
(i'm also not a statistician, and i'm not real sure i did that right.)
