A-share Global Chip LOF 501225 fell to its daily down limit on Aug. 10 while still trading at an 18.02% premium, as several previously high-premium listed open-ended funds retreated after the Shanghai and Shenzhen exchanges released draft LOF delisting rules. The SDIC Silver LOF at one point dropped more than 8%, with its premium also above 18%. The selloff came alongside weakness in China tech shares, with the STAR 50 Index down more than 2% intraday and the Shenzhen Component Index off more than 1%, while the Shanghai Composite's gain narrowed to 0.3%. A fund industry source cited by Yicai said the proposed rules could curb speculative sentiment in QDII and commodity futures LOFs trading at elevated premiums.
