DJI$道琼斯指数(.DJI)$   道琼斯工业指数是30家股票的加权平均值，成份股如下图

PS：加权平均的意思就是A股(A volume)/(30只总量)为其所占的权重。相当于一个相关系数A1，则A股对指数的影响就是 change of A*A1

重要信息：SDOW是跟踪道指日常-3倍的表现。即ETF价格与道琼斯指数波动方向相反，波动幅度约为道琼斯指数的3倍，即道琼斯指数下跌1%对应该ETF指数上涨约3%。

很多人容易把这里的ETF自身所带的杠杆性质和该ETF购买时支持的杠杆倍数搞混。我们看一下如下图示买入SDOW的保证金要求即做多保证金率是75%，即如果我有10万美元，我最多可以买10万/75%=13.33333万(约)的SDOW，杠杆是1.33333。同理，卖空最多可卖10万/90%=11.1111111万(约)，杠杆是1.1111111。
