The short answer is yes. In a mutual fund with a front-end load, there will be a separate sales charge for every new investment beyond the initial investment. There are two exceptions. The first is if an investor is making a contribution of over $1 million. At this level, investors reach a breakpoint where the load percentage goes to zero. The second way is to reinvest dividends and capital gains distributions. The additional shares that are acquired in this transaction are purchased at the net asset value (NAV) price without a sales charge.
The front-end load is charged on the initial investment and any shares that are purchased with new money that enters the fund. If an investor wants to exchange their shares in one fund and move it to another fund within the same fund family. They will not pay a separate sales charge on this transaction.
