假設Daily return滿足normal distribution
令Daily return= 2bp,Daily SD= 125bp
(每年約250交易日,約當年報酬率5%,年標準差20%)
生成十萬筆250日的日回報率
在不考慮ETF cost 的狀況下,250個交易日後,1x、2x、3xETF的回報率:
1xETF median 3.15%,mean 5.11%,SD 21.00%,geomean 3.07%
2xETF median 2.33%,mean 10.48%,SD 45.44%,geomean 2.16%
3xETF median -2.41%,mean 16.13%,SD 75.38%,geomean -2.63%

加入cost:
(1xETF daily cost = 0, 2xETF daily cost=0.6bp, 3xETF daily cost=0.8bp
,約當ER 1%,借貸成本 0.5%)
1xETF median 3.15%,mean 5.11%,SD 21.00%,geomean 3.07%
2xETF median 0.81%,mean 8.84%,SD 44.77%,geomean 0.64%
3xETF median -4.34%,mean 13.83%,SD 73.90%,geomean -4.56%

不考慮cost,比較50% 1xETF + 50% 3xETF不再平衡 vs 100% 2xETF:
2xETF median 2.33%,mean 10.48%,SD 45.44%
50% 1xETF + 50% 3xETF不再平衡 median 0.37%,mean 10.62%,SD 47.85%

比較50% 1xETF + 50% 3xETF不再平衡 vs 100% 2xETF:
2xETF median 0.81%,mean 8.84%,SD 44.77%
