Correlation

Correlation

A statistical measure of how two securities move in relation to each other. A correlation ranges from -1 to 1. A positive correlation of 1 implies that as one security moves, either up or down, the other security will move in lockstep, in the same direction. A negative correlation of -1 indicates that the securities will move in the opposite direction. If the correlation is 0, the movements of the securities are said to have no correlation; they are completely random.
