In the redemption event, during the fundraising period, the Southern CSI 3ETF allowed an institutional investor to redeem the fund shares with yongtai energy, which was in the suspension period. Then, the ticket fell several times after the resumption of trading, which triggered strong dissatisfaction from other fund holders and questioned the "interest transfer". Southern 3ETF agreed in its fund contract that the investment objectives are: closely track the underlying index, and pursue the minimization of tracking deviation and tracking error; However, in practice, the fund completely ignored this basic principle and allowed an institutional investor to exchange a large number of yongtai energy shares for fund shares. As a result, yongtai energy, which only accounted for .16% of the index, finally reached 5.14% of the net value of the South Shanghai and Shenzhen 3ETF, exceeding 3 times.
