Dear prawns, you are not well. I want to ask a fund question, that is, the "China Merchants CSI Liquor Index is positive". The classification of China Merchants CSI Liquor Index and China Merchants CSI Liquor Index are positive, which is the relationship between the parent fund and the sub-fund. China Merchants CSI Liquor Index Classification is the parent fund, and there are two sub-funds, a steady share and a positive share. The parent fund is an over-the-counter transaction, that is, it is purchased in fund companies, banks, Alipay and Tiantian Fund Network. Sub-funds are traded on the floor, not really going to the business hall, but buying with stock accounts, and trading in real time on the secondary market (which can be understood as the stock market). It was stipulated in the previous two years that only those with more than 3, funds can participate in the trading of sub-funds shares, so the threshold is 3,. The active share is a high-risk and high-yield share, and the ups and downs are amplified. The parent fund rises and falls by 1%, and the active share is amplified by about 1.5-2%. The parent fund and the sub-fund can be split and merged with each other, that is, the parent fund can be split into A and B through the exchange. Buying A and B in the stock market can be merged into a parent fund. It is very important to understand this point. The joys and sorrows of the so-called graded funds are all derived from the division and merger here. The specific operation and implementation need strong knowledge and professionalism.
