Let's talk about the concept of discount premium rate. The so-called discount means selling things at a discount. For us, it is treasure hunting, that is, the net value is greater than the market value, and the price of things sold is reasonable. Formula: discount rate = (net value-market value)/net value. On the contrary, it is called premium. When something is expensive, it is greater than its own value. Formula: premium rate = (market price-net value)/net value. The market price is the closing price of the day. For example, yesterday's closing price of security B 150 172 is 1.557 yuan/share, so its market price is 1.557 yuan. The net value is the price announced by the fund company at around 8 o'clock every night. For example, after yesterday's close, it was 1.235 yuan/share. See Shenwan Lingxin Fund Company for details. To put it more bluntly, the discount is positive and can be bought. The premium is negative and should be sold. For example, as of yesterday's close, the premium rate of 150 172 Securities B was 5.3%, while the discount rate of 15020 1B was 3%. As far as the parent fund is concerned, the difference between them is 8.3%, and the leverage part B is at least 1.5 times.

Let's talk about the discount rate algorithm of graded funds in detail. The formula is: discount rate = (net value-market value)/net value, premium rate = (market value-net value)/net value. The graded fund is divided into two parts: A and B, so when calculating the market price and net value, it is necessary to add A and B and divide them by 2. Let's take an example: at yesterday's close, the market price of 15020 1.503 yuan (that is, the closing price), and the net value announced that night was 1.392 yuan (see the website of China Merchants Fund150201.338)/ Similarly, the overall net value of A B is (1.3921.006)/2 = 1. 199 yuan, and the net value of AB is1.199 yuan, which is greater than the market price/kloc-0. The formula should be adopted: discount rate = (net value-market price)/net value = (1.1.1635)/1.199 */kloc-.
