The fund scandals shined the spotlight on the fact that mutual fund managers were putting their interests ahead of the fund shareholders who trusted them, which had much more substantial consequences in the form of excessive fees and the promotion - as the market moved into the stratosphere - of technology funds and new economy funds which were soon to collapse.

The mistakes we make as investors is when the market's going up, we think it's going to go up forever. When the market goes down, we think it's going to go down forever. Neither of those things actually happen. Doesn't do anything forever. It's by the moment.
