Zheng Quan Shi Bao·2025-10-11 00:10Core Viewpoint - The adjustment of margin financing and securities collateral rates for high-valuation technology stocks has created significant volatility in the market, with some stocks experiencing their rates being adjusted from 0% to as high as 70% [1][5]. Group 1: Margin Financing Adjustments - On October 10, Shenwan Hongyuan Securities announced adjustments to the margin financing collateral rates for various stocks, effective from October 13, 2023 [3]. - Stocks such as XianDao Intelligent, Nanji Guang, Manensite, and others saw their collateral rates increased from 0% to rates ranging from 30% to 70% [1][4]. - Notably, stocks like SMIC and Haiguang Information had their rates adjusted to 70%, while Huaxin Yongdao was adjusted to 30% [4][5]. Group 2: Impact of High Valuation - Several stocks, including SMIC and Bawei Storage, were previously set to a collateral rate of 0% due to their static price-to-earnings (P/E) ratios exceeding 300, which restricts their use as collateral for financing [7][8]. - As of October 10, the static P/E ratio for Haiguang Information was reported at 290.68, and for SMIC, it was 246.747, indicating a potential recovery in their collateral rates if they remain below the 300 threshold [10]. Group 3: Market Reactions - The adjustments in collateral rates are expected to compress the leverage space for investors holding these stocks, potentially leading to a need for additional margin or reduction of liabilities [8]. - The dynamic nature of these adjustments means that if a stock's static P/E ratio falls below 300, its collateral rate can be restored [9].
