[原创]指數計算
請問以下PRICE WEIGHT 和EQUAL WEIGHT 計算是否正確
T0 T1
ABC 2.35 2.53
CDE 5.77 6.80
FGH 11.62 13.28
Price weight : (2.35+5.77+11.62)/3 = 6.58
(2.53+6.8+13.28)/3 = 7.536
7.536/6.58 = 0.145
Equal weight 2.53/2.35 *0.33 =0.0252
6.8/5.77*0.33 = 0.0589
13.28/11.62*0.33 = 0.04629
0.0252+0.0589+0.04629 = 0.13 |
