If you believe rates will be rising and we are in a Treasuries bubble (which I believe) since we are at historically low rates/high values then one option is to buy a Short US TBill ETF fund or an Ultra Short TBill ETF.
You will get a very correlated inverse return and thus will make money as rates rise. Go for the ETF versions (just google short tbill etf) as the fees are minimal and liquidity is high.
When rates spike north of some high number buy the Tbills in your IRA and just hold them. My attorney used his retirment to buy bonds when rates were 18% or so and all his partners laughed at him…well he collected 18% interest and then cash in big when rates dropped later.
Alternatively with my IRA funds I’ve started buying 1st Trust Deeds earning 7%-14% depending. Keeping leverage sub 70% I view it as an option to buy at 30% off today’s value that pays me apx 10% in the meantime.
