持仓逻辑 梳理

1+ 1/(1+5%)+ 1/(1+5%)^2 + 1/(1+5%)^3 + ......+ 1/(1+5%)^n = 1 / 5% = 20

1+ 1/(1+5%)+ 1/(1+5%)^2 + 1/(1+5%)^3 + ......+ 1/(1+5%)^13 ≈ 0.5 / 5% = 10

0.5+ 0.5/(1+5%)+ 0.5/(1+5%)^2 + ......+ 0.5/(1+5%)^n = 0.5 / 5% = 10

1+ 1/(1+5%)+ 1/(1+5%)^2 + 1/(1+5%)^3 + ......+ 1/(1+5%)^19 ≈ 0.65 / 5% = 13

0.65+ 0.65/(1+5%)+ 0.65/(1+5%)^2 + ......+ 0.65/(1+5%)^n = 0.65 / 5% = 13
