Subject: Re: Some bond ETFs
Since market close on Wed, the iShares bond ETFs of various durations have all gone up a bit, with the longer-dated maturities showing the most gain.

Meanwhile, the SPDR floating rate ETF FLRN has declined by about 1.5%.

I don't know which iShares bond ETFs you looked at, but in terms of uncertainty, corporate bonds fall, and treasuries go up, with yields moving in the opposite direction.
