What are some recommended ETF funds to park cash with little to "no-risk" while earning yield in retirement accounts where withdrawing is not possible. I have used $TFLO (iShares Treasury Floating Rate Bond ETF) and $TLT (iShares 20+ Year Treasury Bond ETF) but curious some other options.
TFLO is basically "risk free", short duration treasuries with a monthly dividend paid and yield of 3.60% (30 day SEC yield). Low maintenance fee of 0.15%. Price is extremely stable.
TLT is another beast all-together, with pretty significant price movements for a bond. It's trading at near 5 year average lows right now, but yield is 4.93% (30 day SEC yield). Dividends also pay monthly. Same maintenance fee of 0.15%. TLT price can move significantly +/- 15 or 20% but at current prices it seems like a great option to park cash long term with some upside price potential.
