Disinvesting is the most important part of your investment. That sounds illogical but isn't, even if you are not the government. Think about it. The goal of investing is to grow your money. However, this goal is accomplished only when you have taken the money out of your investments and taken it back to your bank account. Therefore, it should be self-evident that the manner and timing of redeeming your investments is an important - in a way, the most important - part of your investments.
