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]
