Group 1 - The core concept of stock market financing and securities lending is that financing transactions profit when the underlying stock rises, while securities lending profits when the stock declines [1] - Stocks eligible for financing and securities lending are marked with an "R" in trading software, and stocks without this designation cannot be traded using leverage [2] - A dedicated credit account is required for financing and securities lending, which is separate from regular stock accounts, and funds within this account can only be used for related transactions [3] Group 2 - Financing liabilities can be repaid by selling the financed stocks or using cash, while securities lending liabilities must be repaid by buying back the same number of stocks or using held stocks [4] - There are risks associated with financing transactions, such as the potential for liabilities to exceed assets if the stock price continues to fall, leading to "margin call" risks [5] - The credit limits for financing and securities lending are not fixed and can be adjusted based on the investor's asset scale, trading activity, and risk management [7] Group 3 - An example of interest calculation shows that for a financing of 1 million yuan at an annual interest rate of 7% held for 15 days, the interest payable is approximately 2877 yuan [8] - In a volatile market, financing and securities lending can be used for "arbitrage trading," buying undervalued stocks while short-selling overvalued ones to profit from the price difference [9] - In a bullish market, financing is primarily used to amplify returns, while in a bearish market, securities lending can capture downward opportunities, necessitating strict position and holding time control [9]

Group 1 - The financing transaction process involves submitting collateral, applying for financing limits, purchasing target stocks, and repaying funds and interest, while the securities lending process includes submitting collateral, applying for lending limits, selling target stocks, and buying back stocks for repayment [1] - The exchange adjusts the list of financing and securities lending targets quarterly, with new targets needing to meet specific criteria such as an average daily trading volume of at least 50 million yuan over the past three months [2] - Cash is counted as 100% collateral, while stocks are subject to different collateral ratios, such as 70% for blue-chip stocks and 50% for ordinary stocks, affecting the maximum financing amount [3] Group 2 - Interest is calculated daily and charged monthly, with penalties for overdue interest calculated on a compound basis, emphasizing the importance of timely repayments [4] - When the maintenance margin ratio is insufficient, it can be supplemented by depositing cash or transferring eligible securities, with the latter being subject to collateral ratios [7] - Trading restrictions are imposed when the financing balance of a single stock reaches 25% of its circulating market value, halting further financing purchases until it drops below 20% [8] Group 3 - Initial trading should involve small amounts to familiarize with the process, followed by recording trading logic and market responses to improve understanding of the dual trading mechanism [9]

Core Concept Analysis - Stock market margin trading consists of two related but opposite trading methods: margin financing and securities lending. Margin financing involves investors borrowing funds to buy specific stocks, using their own funds or securities as collateral, while securities lending involves borrowing stocks to sell and repurchasing them later at a lower price for profit. Both methods incur interest and are limited to designated stocks [1]. Key Operational Differences - Margin financing is a bullish strategy where investors expect stock prices to rise, borrowing funds to buy stocks and selling them later for profit. Conversely, securities lending is a bearish strategy where investors expect stock prices to fall, borrowing stocks to sell and repurchasing them at a lower price for profit. This creates a two-way trading mechanism [2]. Characteristics of Target Stocks - The stocks eligible for margin trading are determined by exchanges, typically including large-cap, liquid, and stable-performing stocks, such as those in the CSI 300 and CSI 500 indices. The list of eligible stocks is periodically adjusted, and stocks removed from the list cannot be traded through margin financing or securities lending [3]. Margin Requirements - Participants in margin trading must pay a margin, which can be cash or eligible securities. The margin ratio for both margin financing and securities lending is usually no less than 50%. For instance, with 1 million yuan of personal funds, an investor can borrow up to 1 million yuan under a 50% margin ratio, with specific ratios adjusted by institutions based on market conditions [4]. Interest and Fee Characteristics - The interest on margin financing and the fees for securities lending are calculated based on the actual number of days used, with annualized rates generally ranging from 6% to 8%. The financing interest is based on the amount borrowed, while the securities lending fee is based on the market value of the borrowed stocks, which must be accounted for in terms of cost and expected returns [7]. Risk Control Mechanisms - A maintenance margin ratio is enforced, calculated as (own funds + market value of held securities) ÷ (financing liabilities + securities lending liabilities). The warning line is typically set at 130%, and the liquidation line at 120%. If the ratio falls below the warning line, additional margin must be provided or positions reduced; if it falls below the liquidation line without timely remedy, institutions have the right to liquidate positions to ensure fund safety [8]. Characteristics of Applicable Groups - Margin trading is more suitable for investors with certain experience and a higher risk tolerance. Margin financing is appropriate for those predicting stock price increases, while securities lending suits those anticipating price declines. Both require investors to accurately grasp market trends and manage risks associated with price fluctuations, making them unsuitable for novice investors or those with conservative risk preferences [9]. Differences from Ordinary Trading - Ordinary trading allows only for buying before selling, with profits dependent on rising stock prices. Margin trading introduces a short-selling mechanism (securities lending), enabling profits in declining markets. Additionally, margin trading incorporates leverage, amplifying both potential returns and risks, while ordinary trading lacks such requirements, making it simpler and more direct [10].
