散户是怎么亏钱的

今天看雪球有一道题,挺基础但很有趣:

  • 一只股票,5元时,小王买了1万元;(试探)
  • 7元时,小王买了2万元;(当初买少了,再买点看看)
  • 10元时,小王买了10万元;(再多买点,争取换个好车)
  • 15元时,小王买了30万元;(早知能涨到15元,当初5元就把家里的钱全买了。现在赚的钱都顶我10年工资了)
  • 20元时,小王借钱买了20万元;(爸,妈,最近手头比较紧,先借点钱用用。)
  • 25元时,小王借钱买了40万元。(兄弟,给我借点钱呗,明年还你50万)
  • 好了,问题来了,这只涨了5倍的大牛股,小王的综合成本是多少?回调多少比例,小王盈亏平衡?

在不考虑交易佣金、借款利息的前提下,综合成本为16.92/股成本。在25元的时候假若来了个32.3%回调,小王立马到了盈亏平衡点。由于有60万是借款,不计算利息的情况下,股价跌到9.86元/股时,小王破产了。

这意味着从一开始的5元到25元,回调到17块(股价是三倍!)的时候什么也没赚!而回调到10元(股价仍翻番)的时候,还破产了!
