做了一下SPY(S&P500)和TLT(20年期以上美國公債ETF)兩支ETF的回測,
說明配置債券的好處
回測時間 2002-07-30(TLT 的上市日) ~ 2022-01-14,合計 19年半
SPY+TLT 為分別持有 50%,當漲破 60% 或跌破 40% 的時候做再平衡,
19年半來再平衡 8次
簡單講一下結論,兩者的相關係數約為 -0.4,
在美大盤下跌時,TLT 都提供了還不錯的保護
ETF 總報酬率 最大虧損 CAGR 報酬率 波動率 夏普值
SPY 645.02% -55.19% 10.87% 12.15% 19.09% 0.64
TLT 236.67% -26.59% 6.44% 7.21% 13.89% 0.52
SPY+TLT 497.33% -23.99% 9.62% 9.61% 9.11% 1.05
