iShares Short Duration High Yield Muni Active ETF (SHYM)

The iShares Short Duration High Yield Muni Active ETF is an actively managed exchange-traded fund from BlackRock's iShares business. The fund seeks to provide income that is generally exempt from federal income tax.

It invests mainly in municipal bonds, including a significant allocation to lower-rated and unrated issues that offer higher yields, while keeping the portfolio's interest-rate sensitivity relatively short. BlackRock's municipal team selects holdings through credit research and active management of sector, state and duration exposures rather than following an index.
