Why did the Shanghai Composite Index go up, but the fund income didn't? The rise of the Shanghai Composite Index does not necessarily mean that the fund's income will rise. The Shanghai Composite Index is a large-scale index, which represents the rise of the market. In most cases, it represents the overall market state, but the market is often divided. There are many cases in which stocks in the two cities have gone up and down. If you buy a fund with the Shanghai Composite Index, then the fund in your hand will go up, because the Shanghai Composite Index Fund tracks the Shanghai Composite Index, so when the index goes up, the fund will go up; If you buy other index funds, then its rise and fall are related to other indexes, such as Shenzhen Stock Exchange Index, Growth Enterprise Market Index and Shanghai and Shenzhen 300 Index Funds. Whether to buy a plate fund or a stock fund depends on whether the position of this plate and stock has risen. If the position of the sector or fund does not rise, the fund will naturally not rise.
