<<Not trying to start anything with Paul, but the short term trend in DELL is down>> Coward!! <VBG> So let me start something with you. A Bollinger band is a surrogate for a confidence interval. Yet those pseudo-confidence intervals (Bollinger bands) are statistically undefined. This is in sharp contrast to a statistician's confidence intervals of +/- x-standard deviations (+/- 1 standard deviation encompasses about 67% of all observations). And no statistician I know would ever put any stock (pun intended!) in one or two observations outside a confidence interval. BTW, how do you define short-term? 1 week, 1 month, six months, or is it purely arbitrary? Secondly, how do you correct for general market conditions? Regards, Paul
