什么是无套利区间?无套利区间是指贵金属不同品种之间套利机会为零的运行区间,一般资金实力较强的投资者,会持有至少两个以上的投资品种,单是贵金属投资市场,就持有黄金白银现货及期货品种,然而套利过程中也会存在“盲点”,该“盲点”就称为“无套利区间”,那么我们如何找到无套利区间,并且学会规避进场交易之后却无法获利的窘况呢?下面大田环球小编带各位炒金达人简要了解。
一、无套利区间的形成
无套利区间是指投资者交易两种相似的投资品种期间,在一定的价格运行区间内,交易单平仓之后的交易成本投入等于或高于套利金额,意味着我们交易套利品种的回报仅仅与投入持平,甚至低于投入,导致无法创造额外盈利。
二、发现无套利区间的意义
1、 发现无套利区间,可以帮助我们设定更为科学的套利交易策略,避免额外的资金流出,甚至引发失误风险。
2、 通过无套利区间的大小,我们能够了解套利品种的交易成本大小,因此能适当调配资金进场比例,即使套利区间出现,我们也能确认此时是否为最佳的进场时机,避免操作失误。
三、确认无套利区间的例子
A先生于日内买入一手国际现货黄金,同时卖出1手上海黄金期货,每手上海黄金期货的手续费为10元,国际现货黄金不含任何手续费,只有点差,由于A先生在大田环球贵金属开设的是微点差账户,买入时黄金点差为0.13美元/盎司,即13美元。那么A先生操作国际现货黄金和上海黄金期货这两品种的无套利区间为:
1、 交易成本为=上海黄金期货手续费+国际现货黄金点差=10元(CNY)+13美元*6.2502(中间价)=10+81.2526=91.2526元,91.2526元/6.2502(中间价)=14.6美元(保留小数点后一位数)
2、 由交易成本可得,无套利区间为14.6美元,由于黄金期现货品种采取杠杆交易制,以100的杠杆比例来计算,国际金价盘面无套利区间为0.14~0.15美元,当上海黄金期货价格向下移动了一定区间,产生的实际保证金变动为91.2526元,或国际现货黄金价格向上移动了约0.14美元时,以及二者之间价差在货币汇率转换为同一计价单位(美元)以后,出现了0.14~0.15美元的区间,该区间就是无套利区间。
