Whether a given investment is highest return option for your investment does not change with interest rate. So it does not matter how high interest rates will go.
One thing you might be looking at, though, is if high interest rates somehow affect a given business. If a business relies on being able to get a lot of debt readily and cheaply they might be worse option than one that does not.
