Since the net value of QDII funds is generally announced in a day or two, the net value we see on the software is not the latest. Many friends left messages asking how to estimate the net value of US stock and Hong Kong stock index funds. Here are some examples. Case 1: SMEs in Hong Kong take SMEs in Hong Kong as an example to illustrate how index funds estimate their net worth. The following figure shows the net value of Tian Tian Fund website Hong Kong Small and Medium-sized 20 16. 12.28. Investors can only see the net value on the 27th. If we want to buy the fund in the market on the 28th, if the transaction price is lower than the actual net value, it is equivalent to buying at a discount. How can we estimate its net value? 65438+net value on February 28th (a) = 65438+net value on February 27th (b) * (1+the small and medium-sized stock index of Standard & Poor's Hong Kong China rises and falls on February 28th (c)+the exchange rate of Hong Kong dollar against RMB rises and falls on February 28th (d)).

Suppose we consider whether to invest in small and medium-sized enterprises in Hong Kong when the market closes, we can estimate their net worth according to the above formula. February 27th 14:55, where B= 1.0338, C= 1% and D=0.05% are substituted into the formula to calculate A =. Since A-shares closed at 15:00 and Hong Kong stocks closed at 16:00, as long as Hong Kong's small and medium-sized index did not plummet at the end of the session, there was a certain discount (safety mat) for buying. Due to the continuous rise of small and medium-sized enterprises in Hong Kong, the net value of 1.0456 on February 28th was 1. 14% (the actual increase was 1.0338+05%). The actual discount of 1. 15% at the price of 1.0338 is a very cost-effective transaction. If we want to estimate Huabao's net oil and gas value, we can change the index tracked in the formula to oil and gas exploitation index (XOP), and if we want to estimate the net oil value in South China, we can change the index tracked in the formula to American crude oil continuous index (NXCLYO). Of course, this is only an estimate, because there will be some errors in the fund's index tracking, and the transaction friction loss will also affect the net oil value. When we invest in a target, we must do more research and not start betting in a daze. Understanding the principle of QDII fund net value calculation has the following advantages: buying investment targets at a discount and increasing safety mats. When the investment target has a large premium, it can be sold or rotated (for example, the high premium of 5 13500 is rotated to161125). Avoid blindly buying with the wind, causing huge losses.
