Not a good plan especially in a taxable account. This is referred to as buying a dividend. You will be paying for the full NAV of the fund and when the distribution is accomplished, you will be taxed on your own money (the distribution), the NAV will decrease by the same amount. If you wait until after the distribution date to purchase, you take advantage of the lower NAV and pay no tax on a distribution. The only time it wouldn't matter is if you are in a 0% cap gains bracket or a tax free or tax deferred account. Still no advantage there as the increase in NAV providing the distribution happened prior to your purchase. That's when the money was made.
