SYSB

SYSB provides systematic exposure across US dollar-denominated bonds, including Treasuries, securitized debt, investment grade corporates, and high yield. The index applies rules-based tilts: an economic regime overlay that adjusts high yield allocations, credit quality screening to reduce default risk, a value tilt favoring bonds with stronger risk-adjusted spreads, and interest rate momentum to set target duration. These systematic signals aim to balance income and risk across changing market environments. Prior to September 2, 2025, SYSB traded under the name iShares U.S. Fixed Income Balanced Risk Systematic ETF, ticker FIBR, and tracked the Bloomberg U.S. Fixed Income Balanced Risk Index. Prior to Jan. 26, 2024, it was called the iShares U.S. Fixed Income Balanced Risk Factor ETF.
