PART A
Calculate each component cost and total trading cost for this OTS investment on a per share basis
这个per share值得玩味
在算
Commission
$0.05
Price impact
$0.25
$15.75 – $15.50
Trader timing
$15.50 – $15.00
直接相减得价差
但算
Opportunity
$1.20
Calc for $1.20: ($18–$15)×40,000/100,000
是价差*未成交数/订单总数
那Commission、Price impact、Trader timing也应该是
价差*成交数/订单总数
才合理呀
能否解释一下，谢谢！
