+ 构造一个事件驱动策略看下盈利预增效应是否长期有效
+ 策略思想 ： 以企业净利润预增预报为事件驱动，卖出同期持仓（上个换仓期到本次换仓）中收益率最low的股票，买入盈利预增的股票。
+ 回测区间 ： 07年 —— 今

+ 从回测结果来看业绩预增事件在熊市中效应并不显著，12年以前跑得也没之后的好。
+ 从统计数据来看，07年后逐年有更多的上市公司以业绩预告的方式与公司股东进行互动交流,股民朋友们也越来越注重业绩预告，并在二级市场给予及时的回应。
+ 呀！才发现回测有新功能了——回测详情，有更多统计信息了！！！好棒！
+ PS：从回测详情看好多业绩预增的公司报告发布后第二天开板涨停啊！看回测详情数据~新技能get.
