Core Points - Stock financing is a method for investors to amplify their investment scale through broker credit trading mechanisms, reflecting regulatory requirements for market stability [1] - The financing mechanism is limited to designated stocks published by exchanges, typically characterized by large market capitalization, good liquidity, and stable financial conditions [2] - The initial margin requirement is no less than 50%, with actual ratios dynamically adjusted based on the risk level of the underlying assets [2] Trading Characteristics - The sensitivity to price fluctuations is significantly higher than ordinary trading, requiring stronger risk tolerance from investors [3] - A maintenance margin ratio of at least 130% is mandated by regulations, with potential forced liquidation by brokers if this ratio is not maintained [3] - Financing transactions do not have a fixed term, allowing investors to decide on closing positions based on market conditions [3] Market Linkage - Changes in financing balance reflect market sentiment, with continuous growth in financing balance alongside index increases indicating strong short-term momentum [5] Operational Strategies - Prioritize large-cap stocks with an average daily trading volume exceeding 1 billion and minimal price volatility over the past three months [6] - Enter positions when stocks break through key moving averages with increased volume, avoiding high-price chasing [6] - Limit the position size of a single financing stock to no more than 30% of the total assets in the credit account [6] Closing Decision Logic - Close positions decisively upon reaching preset profit targets of 10%-15% after interest deductions, avoiding the pursuit of maximum returns [7] - Implement stop-loss measures when stock prices fall below the purchase price by 5%-8% or when financing balances decrease significantly [7]
