文档介绍：several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measuremen寸与交易所结清差额，同时在股票现货市场上出售相应的一揽子股票，获利了结。
情形2：
假设，那么股指期货相对于目前的股票现货价格被低估，我们可以根据股指期货标的指数的编制方法融入一揽子股票并卖出，同时在期货市场上以的报价等比例开多仓，以完全覆盖现货空头头寸风险。
开仓完成后，假设期货合约报价和现指向均衡价格收敛，那么我们可以提前买入一揽子股票，并卖出股指期货合约，平掉先前的股指期货多头头寸，了结交易。
开仓完成后，股指期货合约报价和现指并未向均衡价格收敛，我们继续持有头寸，直到期货合约到期清算，此时期货合约多头头寸与交易所结清差额，同时在股票现货市场上买入相应的一揽子股票，获利了结。
二、股票价格指数现货—期货套利操作
1、现多期空套利操作：
several group number, then with b ± a, =c,c is is methyl b two vertical box between of accurate size. Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
