The estimated increase of the fund is the net increase calculated by some fund websites according to the proportion of fund positions and the ups and downs of Shanghai and Shenzhen stock markets on that day. As the fund's shareholding may change dynamically, the expected increase of the fund is not the final increase, and the actual increase is subject to the official announcement of the fund company.

1. First of all, all positions of the fund will only be announced in the semi-annual report and the annual report. The quarterly report only publishes the top ten awkward stocks of the fund. Some funds may hold hundreds of stocks. Therefore, the estimation of the top ten heavyweights is inaccurate, which will be quite different from the actual net value. 2. Secondly, the annual report and quarterly report of the fund disclose the data at the end of each quarter, and there is no news of the latest position changes of the fund. If the market fluctuates greatly, the fund manager may make large-scale position adjustment and stock exchange after the release of the periodic report, but the platform still estimates the net value according to the previous position data, which will naturally lead to a big difference between the valuation and the net value.

(1) The rise and fall of the net value is affected by the trend of the actual target. For example, if the average value of the top ten heavyweights rises, the net value of the fund will rise that day. The average income of the top ten heavyweights will decrease, so the net value of the fund will decrease. Therefore, the difference between the two references will inevitably lead to the difference between the valuation and the actual increase. Investors should buy funds according to the actual net value, not according to the valuation. Valuation is for investors' reference only, not as a basis for buying.

(2) Some investors often say that the problem of fund managers stealing the column is caused by new investors' ignorance of the operating mechanism of fund products. In fact, the foundation you buy forms special fund assets and sets up an independent fund account, which is managed by the custodian. Take the Great Wall Environmental Protection Advantage Stock Fund managed by Alipay Gold Medal Manager Yang as an example. The fund is managed by China Construction Bank. Fund managers are only entitled to invest in fund assets. The custody mechanism of fund assets determines that there are two institutions that can help you invest and save money. The fund net value of the fund accounting of the fund company and the fund accounting of the custodian bank on the liquidation day of each trading day plays a role in mutual supervision of the fund assets; In addition, the annual report of the fund also needs to be audited by an accounting firm. Under these strict monitoring systems and perfect operating procedures, the fund's financial security has been guaranteed.
