总共$2,200,分4次购买,股价变化如下,
March 15,$3
April 15, $5
May 15, $10
June 15, $4
我们可以有三种方法:
1)Dollar cost averaging
每次$550,购得486股(183+110+55+138),成本=$4.53
2)Share averaging
每次100股,购得400股,成本=$5.50
3)Conditional Dollar averaging (Delay if price too high)
设$7,为price too high
每次$550,购得569股,成本=$3.87
3-1)March:183股 ($550)
3-2)April:110股 ($550)
3-3)May:Skip due to high price
3-4)June:275股 ($550+$550)
