What Investors Ask About iShares Core Universal USD Bond ETF (IUSB)

What does iShares Core Universal USD Bond ETF do?

The iShares Core Universal USD Bond ETF (IUSB) aims to replicate the investment results of an index composed of U.S. dollar-denominated bonds that are rated either investment grade or high-yield.
