Core Viewpoint - Nine A-shares, including SMIC and Roadbridge Information, have had their financing and securities margin rates adjusted to zero due to their static price-to-earnings (P/E) ratios exceeding 300 or being negative, as part of a dynamic risk control measure by several securities firms [2][5][10].
