I've got around $20k that's been sitting in a Fidelity investment account, all in Fidelity's Total Bond Fund. I factor this into my overall allocation of 80% Total World Stock / 20% Total Bond. However, I'd like to shift this into something which mirrors my overall allocation, but since I'm primarily in Vanguard funds I'm not sure of Fidelity equivalents.
What are some low fee Fidelity funds which would give me this equivalent exposure? Can I invest in Vanguard funds/ETFs within the Fidelity HSA, or would the fees to do this be high? Thanks in advance!
