融资融券业务是如何运作的？参与融资融券投资有哪些风险？

Group 1: Core Concept - Margin trading allows investors to borrow money or stocks from securities companies to trade, amplifying potential returns but also risks [1][3][5] Group 2: Margin Financing - Investors can borrow money to purchase stocks if they believe the stock price will rise, enabling them to buy more shares than they could with their own funds [1][3] - For example, if a stock is priced at 10 yuan and an investor wants to buy 10,000 shares but only has 50,000 yuan, they can borrow 50,000 yuan to complete the purchase [1] - If the stock price rises to 12 yuan, selling the shares would yield 120,000 yuan, allowing the investor to repay the loan and keep the profit [1] Group 3: Margin Short Selling - Investors can borrow stocks to sell if they believe the stock price will decline, allowing them to profit from the price difference [3][5] - For instance, if a stock is priced at 15 yuan and an investor borrows 10,000 shares to sell, they would receive 150,000 yuan [3] - If the stock price later drops to 10 yuan, the investor can buy back the shares for 100,000 yuan, returning them to the lender and keeping the profit [3] Group 4: Participation Requirements - Securities companies assess investors' assets, trading experience, and risk tolerance before allowing participation in margin trading [3][5] - Investors must have at least six months of trading experience and an average asset of over 500,000 yuan across 20 trading days to qualify [3] Group 5: Risks of Margin Trading - Leverage risk: Margin trading amplifies both potential gains and losses, which can lead to significant financial loss if stock prices move unfavorably [5][7] - Forced liquidation risk: If the value of the investor's account falls below a certain threshold, the securities company may require additional collateral or liquidate positions to cover the loan [5][7] - Market risk: Stock prices can be volatile due to various factors, which may adversely affect the returns from margin trading [7] - Interest rate risk: Changes in interest rates can increase the cost of margin trading, reducing overall profitability [7]
