Nil assets t Consistency of Performance Assume that fund XYZ has reported spectacular results for the last three-years. Not if those results were a fluke. If a fund company has one or two great funds, it could simply mean that it has one or two good fund managers. If a family has half a dozen or so of funds that consistently out-perform their peers, it means much more. Strong, consistent performance by various funds within the family could mean a lot of good things.
Family is less prone to fund managers' defection.
Objectives and results will be less affected. For you as an investor, the long-term implications of those features are enormous. In the least, you will increase your chances of maximizing long-term returns. Also, the larger the number of consistent above average performing funds within the family, the more choice you have to build a diversified portfolio within the family. Therefore, it is important for you to ensure that your mutual fund company provides you with an adequate choice of funds that address all your investment needs, by covering the largest number possible of mutual fund categories.
