我去查了一下上调前的点位，分别是24000、8600、77点和4200点。 有点难绷，你们发现了没，其实真正上调的是前三个指数，因为开年涨了不少，最后的沪深300是混在里面充数的，目标价只从4200上调至4220，连0.5% 都不到。熊大和熊二以后吃饭都没法坐一张桌了。 一季度还剩下3个交易日，沪深300指数累计下跌0.4%，又成功浪费了大家三个月的时间。但这只是基本操作，因为就算和十年前，2015年的3月26日相 比，沪深指数也只是累计下跌了0.78%。 十年间上上下下，既让散户高高兴兴玩了10年，又避免了让散户赚到钱，这就是a股的社会价值。什么炒股有风险，投资需谨慎，这话说给新手听有用 吗？根本当放屁好嘛。要我说就应该让每一个新开户的韭菜，手写10遍："A股很好玩、A股浪费时间、A股不挣钱"，散户只要接受了这个设定，炒股的 时候就不会怨气冲天。 今天a股成交1.15万亿，成交量进一步萎缩，个股中位数+0.63%还不错，和前几天相反，a股今天是头凉脚热，小微盘股大面积反弹，所以在计算上涨个股 数量的时候很占优势。 | 先 | 代码 | 名称 | 涨幅％ | 现价 | | --- | --- | --- | ...
