post er move：
move second day after last er: -11.3%
comments: negative, reason for that may be revenue miss.
一年之内没有连续两个季度 move down。
5个季度有两个down，三个up。上次是down。
所以这次up 的机会大， 听起来too naive 是吧？其实上市公司都是要尽量避免连续bad move 的。
trading：
trading flat at 220 where options exert maximum pain,which is resistance as well as support.
comments: positive.this is good as it is not priced too high to prevent a move after er.
surprise 估计：
中国销售惊人， 会增加总收入和eps。
conclusions:
projected move after er：>8%
upside,expect least move >5% from 220. 240 may be reached or broken.
