NO.PZ2015121801000035问题如下investor purchase100 shares of a stofor $34.50 per share the beginning of the quarter. If the investor solall of the shares for $30.50 per share after receiving a $51.55 vinpayment the enof the quarter, the holng perioreturn is closest to:A.−13.0%.B.−11.6%.C.−10.1%.is correct.−10.1% is the holng perioreturn, whiis calculateas: (3,050 −3,450 +51.55)/3,450, whiis compriseof a vinyielof 1.49% = 51.55/(3,450) ana capitloss yielof −11.59% = –400/(3,450).这里为什么不用连续复利？用ln来求？
NO.PZ2015121801000035 −11.6%. −10.1%. C is correct. −10.1% is the holng perioreturn, whiis calculateas: (3,050 −3,450 +51.55)/3,450, whiis compriseof a vinyielof 1.49% = 51.55/(3,450) ana capitloss yielof −11.59% = –400/(3,450).老师您好，我有点不了解这个知识点在哪，为什么要除以3450，而不是3050来求解挣了多少钱的率呢谢谢老师啦
这里如果求bank scount yielFV用哪个数呢？FV要不要加上v?
请问不是 1+HPR = (30.5*100+51.55-34.5*100)/34.5*100 1+HPR=-0.101 hpr=-1.101吗
算出3050+51.55-3450除以3450这个为什么不是HPR？为什么这个值还要再加上分红的百分比？
