The transaction of OTC funds is generally called subscription and redemption, and its rates range from 1% to 2%, some of which may be lower and some may be higher. See the website of the fund company for details. The subscription and redemption of OTC funds adopt the principle of unknown price, that is, when you buy or sell, you don't know the specific transaction price of the fund. Generally speaking, if you are in the afternoon, 3. 00, the transaction price is the net value of the fund on that day, and after this time, the transaction price is the net value of the fund on the next day. There are two ways to pay dividends for OTC funds: one is cash, and the other is dividend reinvestment (if it is held for a long time, this way can make investors get more investment income, which is equivalent to compound interest).
Eligible funds between the same fund company can be converted. Different fund companies have different rules and can search online.
