3 Vanguard ETFs with low fees and wide exposure may double in 5 years with falling interest rates, assuming 15% annualized returns.

Needing 15% annualized returns, which exceeds the S&P 500's long-term average, to achieve this growth, the author predicts this potential due to the anticipated tailwind of falling rates and the current valuation gap.
