两融折算率呈现“有升有降”

Core Viewpoint - The adjustment of margin trading collateral and conversion rates by Shenwan Hongyuan Securities and Western Securities reflects a dynamic risk control strategy in response to the high valuations and losses of certain companies, particularly focusing on the stocks of SMIC and Bawei Storage [1][2]. Group 1: Margin Trading Adjustments - On October 10, Shenwan Hongyuan Securities and Western Securities announced adjustments to the margin trading collateral and conversion rates, effective from October 13 [1]. - The conversion rates for SMIC and Haiguang Information were raised from zero to 70%, while several other companies saw their rates adjusted to between 30% and 65% [1]. - Conversely, the conversion rates for Tongyu Heavy Industry and Chuangyitong were reduced from 65% to zero, indicating a mixed trend in adjustments [1]. Group 2: Market Reactions and Valuation Changes - Following the adjustments, stocks such as SMIC and Bawei Storage experienced significant declines, with SMIC's static P/E ratio exceeding 300, leading to its conversion rate being set to zero [1][2]. - As of October 10, the static P/E ratios for SMIC, Bawei Storage, and XianDao Intelligent were reported at 276.75, 279.33, and 299.93, respectively, allowing for the re-establishment of their conversion rates to 70% and 65% [2]. - The adjustments in conversion rates are seen as a reflection of brokerage firms' risk management practices, particularly for high-valuation and loss-making companies [2]. Group 3: Implications for Investors - The zero conversion rate indicates that while investors can still finance with sufficient margin, the stock cannot be used as collateral, impacting the available margin for further financing [2]. - For example, a stock with a market value of 1 million yuan that previously had a 70% conversion rate would provide 700,000 yuan in available margin, which would be lost if the conversion rate is set to zero [2].
