四种股指除了周四,其它四个交易日都是涨多跌少
而周四明显跌的天数占比多了至少7%,结论是法定杀跌日是存在的

按公历月份统计一下各月份的涨跌占比

结论:1.不同月份的涨跌占比确实存在比较惊人的差别
两个十年涨跌月份发生了较大的改变
二月份涨跌比最大可达4:1,二月份通常也是春节假期结束,
内在逻辑我想不出来,也许压岁钱买股[s:ac:哭笑]
十一月上涨占比明显大于下跌,且四个指数同步
2.上证指数跟深圳成指在6月涨跌比例不同步
3.创业板至今正好10个年头,显得很短,数据越少,统计偏差越大,
看起来创业板的行情往往独立于主板

结论: 小幅波动占多数,且涨跌占比趋于平均,5%以上的大涨大跌, 跌幅超过5%的占压倒优势
追涨贪婪的动力终究没有杀跌的恐惧强烈
