几个数学计算结果
(1+10%)*(1-10%)*(1-10%)=0.891
(1-10%)*(1+10%)*(1+10%)=1.089
(1-10%)*(1-10%)*(1-10%)=0.729
(1+10%)*(1+10%)*(1+10%)=1.331
(1+10%)*(1+10%)*(1+10%)=1.331
(1+10%)*(1+10%)*(1+10%)*(1-10%)=1.1979
(1+10%)*(1+10%)*(1+10%)*(1-10%)*(1-10%)=1.07811
(1+10%)*(1+10%)*(1+10%)*(1-10%)*(1-10%)*(1-10%)=0.970299
(1+10%)*(1+10%)*(1+10%)*(1-10%)*(1-10%)*(1-10%)*(1-10%)=0.8732691
(1+10%)*(1+10%)*(1+10%)*(1-10%)*(1-10%)*(1-10%)*(1-10%)*(1-10%)=0.78594219
即,一直股票经历3个涨停之后,考虑大家都想着只要不赔钱我就不卖,即便再连跌停3次,大家也不会出手,但是到第4个跌停时大家的心态就该崩溃了!
因为大家清楚的知道如果再来个跌停,那么自己的亏损将达到21.4%,需要3个涨停才能回本
0.78594219*(1+10%)*(1+10%)*(1+10%)=1.046089
(1-10%)*(1-10%)*(1-10%)=0.729
(1-10%)*(1-10%)*(1-10%)*(1+10%)=0.8019
(1-10%)*(1-10%)*(1-10%)*(1+10%)*(1+10%)=0.88209
(1-10%)*(1-10%)*(1-10%)*(1+10%)*(1+10%)*(1+10%)=0.970299
(1-10%)*(1-10%)*(1-10%)*(1+10%)*(1+10%)*(1+10%)*(1+10%)=1.0673289
即,一直股票经历3个跌停之后,即便再连涨停4次,也才实现6.7%的涨幅。如果考虑到回本,那么大家需要等到第四个涨停时卖出。
