Two different things.

The parent funds of graded funds include Class A funds (agreed income share) and Class B shares (leveraged share).

If you buy and sell A and B separately, you can only open one securities account, that is, the stock account is in the secondary market.

Buy and sell like stocks,

The secondary market price is determined according to the relationship between supply and demand, and has little to do with the actual net value, which is the core of the problem.

So there will be a problem of premium discount.

Generally, the off-exchange net value of Class A shares is 1.0 yuan, and the on-exchange transactions may only be 0.9 or even 0.8 yuan, which is a discount.

Generally speaking, if you don't want big money, it's easy to hit the price (the securities account buys the parent fund, splits it into AB, and then abandons A to pursue the leverage effect of B)

The actual net value of B-level (150 153) on the Growth Enterprise Market Index of Fuguo.

The premium is close to 20%

Graded B funds have leverage effect. The previous index just rose, and everyone rushed to grab it, which naturally raised the price and even the daily limit. After a short-term sharp rise, large funds fled, and everyone began to run again, causing trampling and easily falling sharply.

To put it bluntly, B is a short-term speculative variety, which has nothing to do with the actual trend of the index, but it is easy to be amplified.
