WebMar 30, 2024 · By Victorio Stefanov. The correlation coefficient measures the correlation between two assets. It is a statistical measure between the two asset variables that ranges between -1.0 and 1.0. The lowest correlation two assets can have between each other is -1.0 meaning as one of the two correlated assets moves up, the other moves down in the … Webcorrelation and regression. Following, we present a longer review of ways to interpret the correlation coefficient. This presentation demonstrates that the correlation has developed into a broad and conceptually diverse index; at the same time, for a 100-year-old index it is remarkably unaffected by the passage of time.
