Buy Grade A, and then select the option that the transaction client has fund merger and split. Go in and merge and convert it into a parent fund, and then sell it when the parent fund rises. Theoretically, the loss can be reduced by about 3- 10%.

Do T in intraday trading, buy and increase positions to 50% when it falls on the same day, and then sell the original shares when it rises on the same day. Theoretically, doing T can reduce the cost by about 20% (I often do it, but only when it goes up).

Lower your position to a position where you can sleep and recognize some of it.

Stick to it, it's ok to go up, but it may be risky to go down and lose everything.

To sum up, if you are a novice, it is recommended to choose 1, if you are an old hand, it is recommended to choose 2, and if you have strong risk tolerance, it is recommended to choose 3. 4 is not recommended.

Stock trading is risky, and graded funds are more risky, so we should pay attention to it in the future.

Further reading: Structured Fund, also known as "structured fund", refers to a fund variety with two levels (or multiple levels) of risk-return performance with certain differentiated fund shares by decomposing the fund income or net assets under a portfolio. Its main feature is to divide the fund products into two or more types of shares and give different income distribution respectively. The sum of the products of the net value of each sub-fund of the graded fund and the share ratio is equal to the net value of the parent fund. For example, the net value of the parent fund split into two types of shares = the net value of class A sub-base X A share%+the net value of class B sub-base X B share%. If the parent fund is not split, it is a general fund.
