This study then evaluates the co-movement among funds within the same risk level and among funds across different risk levels. This study concludes that within any given risk level, the performances of at least seven funds exhibit strong co-movement. This study also shows the influence of the global economy on the correlations among different funds. Finally, investment recommendations are provided based on the findings.
