在股票图表页面右上角点击黄色“融”图标,系统会弹出提示框,说明该股票是否支持融资或融券,以及相关的保证金比例、参考利率等内容。

特别说明:

  • 部分个股由于流动性、风控或监管原因,可能暂不开放融券做空,即使支持融资做多。
  • 如果看到“卖空池剩余 = 0”,说明目前暂时没有可用融券额度,但股票本身是支持做空的。
  • 如果初始保证金是100%,或者提示‘--’,表示不支持融资或者融券

1.做多初始保证金(Initial Margin for Long Position)

定义: 做多初始保证金是指投资者在开立多头仓位(即买入股票)时,必须存入保证金账户的最低金额。这通常是股票购买价格的一部分,由交易所或经纪商规定。

举例: 如果交易所规定的初始保证金比例是50%,且投资者想买入价值10,000美元的股票,他们需要存入5,000美元作为初始保证金。

2.做多维持保证金(Maintenance Margin for Long Position)

定义: 做多维持保证金是指投资者在持有多头仓位期间,账户中必须保持的最低保证金水平。如果账户保证金低于此水平,投资者会收到追加保证金通知(margin call),要求存入更多资金或卖出部分股票。

举例: 如果维持保证金比例是30%,且投资者的股票市值降至8,000美元,他们需要保持至少2,400美元(8,000美元的30%)的保证金。如果账户中的保证金低于2,400美元,投资者需追加保证金。

3.做空初始保证金(Initial Margin for Short Position)

定义: 做空初始保证金是指投资者在开立空头仓位(即卖出借来的股票)时,必须存入保证金账户的最低金额。这是为了保证投资者有能力在股票价格上涨时承担潜在损失。

举例: 如果交易所规定的做空初始保证金比例是50%,且投资者想卖空价值10,000美元的股票,他们需要存入5,000美元作为初始保证金。

4.做空维持保证金(Maintenance Margin for Short Position)

定义: 做空维持保证金是指投资者在持有空头仓位期间,账户中必须保持的最低保证金水平。如果账户保证金低于此水平,投资者会收到追加保证金通知。

举例: 如果维持保证金比例是30%,且投资者卖空的股票市值上升至12,000美元,他们需要保持至少3,600美元(12,000美元的30%)的保证金。如果账户中的保证金低于3,600美元,投资者需追加保证金。

5.卖空参考利率(Short Interest Rate)

定义: 卖空参考利率是指投资者在借入股票进行卖空操作时,支付给股票出借人的利率。这是卖空交易的成本之一。

举例: 如果卖空参考利率是5%,且投资者借入价值10,000美元的股票进行卖空,他们每年需支付500美元的利息(10,000美元的5%)给出借人。

6.卖空池剩余(Short Sale Pool Remaining)

定义: 卖空池剩余是指可供借出以进行卖空操作的股票数量。这个数值会随市场需求变化,如果卖空需求高,卖空池剩余会减少,反之亦然。

举例: 如果某只股票的卖空池剩余为50,000股,表示目前还有50,000股股票可供投资者借入进行卖空操作。当更多投资者借入股票进行卖空时,这个数值会相应减少。

通过理解这些术语及其操作,可以更好地掌握美股和港股交易中的保证金要求和风险管理。
