What you are talking about is the gap caused by the irregular conversion of graded funds, which will change its actual value. The gap caused by irregular conversion of graded funds is actually similar to stock ex-dividend, but its practical significance will lead to a one-time qualitative change in its price leverage. For irregular conversion, it can be roughly divided into low conversion and high conversion. This 150206 is applicable to all of you (note that this 150206 is the Class B share of the graded fund), and the low point conversion is when the net value of Class B share of the graded fund is lower than the threshold of 0.25 yuan on a certain day (the general stock category is set according to this value, but some graded funds do not have such a low point conversion valve, see the fund prospectus for details). Will cause this graded fund to perform this low conversion procedure. As for the high-point conversion, when the net value of the parent fund of the graded fund reaches the threshold of 1.5 yuan or 2 yuan (note that this is the parent fund, not the B-share of the graded fund, how to do it depends on the prospectus of the fund. Different graded funds have different regulations, and some funds have no high-point conversion. The normal net value of fund shares will be announced after the end of each trading day. For low-point conversion, it will lead to a one-time reduction in the leverage of the high-level benchmark of Class B shares, while for high-point conversion, it will change its value-income composition, some of which will be converted into parent fund shares, and some will increase the leverage of low-leverage Class B shares.
