1. In graded funds, an index fund is generally divided into two parts, one is suffix A, and the other is suffix B. A is fixed income, and B is equivalent to borrowing money from A for stock trading, so A can be simply regarded as a bond and B as a leveraged index fund. In fact, the relationship between Military Industry A and Bank A is not very big, which only shows what industry index the parent fund tracks. However, Military Industry B and Bank B are not only the relationship between military industry and banks, but also have a dual relationship.

2. In general funds, according to the charging situation, there are also some suffixes with ABC, such as Tian Hong CSI 500 Index A and Tian Hong CSI 500 Index C, among which A and C are different from the above-mentioned graded funds. A charges subscription and redemption fees, but does not charge sales service fees, and C does not charge subscription and redemption fees (punitive redemption fee of 1.50% is charged within 7 days). So we will find that in the daily net worth data, C is always a little less than A. Generally, if it is held for a long time, it is recommended to buy A, and vice versa. The suffix with B is the back-end charge, which means that there is no subscription fee at the time of subscription. Only when it is redeemed, a certain fee will be charged according to the number of years you hold, even free.

3. According to the scale of your subscription, it is divided into AB. Generally, a one-time subscription of more than 5 million yuan can enjoy the discount of B. Relatively speaking, the threshold is relatively high, the cost is relatively low, and even a fixed subscription fee is charged. Here b is mainly a large number of institutional subscription funds. Individuals generally choose a.
