There is no escape from taxes other than being foolish enough to avoid ALL profits in order to avoid losing PART of those profits to taxes. I have had no excessive trading problems so far. At Invesco I have never traded any fund more than four times in a year. The very short-term trades in the contest are mostly psychologically driven all your eggs in one basket moves. To get the returns it must be with your whole portfolio.
Any distribution is held in cash until the next exchange to make the paperwork simple.
The date of purchase of one fund is the date of sale of the previous fund. Money market pays no interest and should not be expected to ever be used by the pony express. There is a limit to the amount of money one can manage effectively. If I were managing all the investment capital in the world the best I could manage to gain would be market return. My return would be market return.
