      For example, DELL and CPQ are two stocks that often have a positivecorrelation. If they were 100-percent positively correlated (+1), then aone-point move in DELL would be followed by a one-point move in CPQ, orvice versa. If these two stocks were 50-percent positively correlated(+.5), then a one-point move in DELL would be followed by a 1/2-point movein CPQ, or vice versa. If these two stocks had no correlation whatsoever(0), then a one-point move in DELL would not cause CPQ to move at all.
