The 90 % solution
As much as 90% of the performance of today’s mutual funds is explained by the concurrent performance of the overall stock market. For managers of these funds, even the so-called “5-star” funds, that 90% is a problem because they are hard-pressed to outperform the market averages. The 90% solution is about understanding the most important factors impacting today’s stock market, how they influence performance and how they can be used to produce higher returns.
