AB Core Bond ETF (CORB)

AB Core Bond ETF is an actively managed exchange-traded fund from AllianceBernstein (AB) that invests in a diversified portfolio of primarily investment-grade U.S. dollar-denominated fixed income securities.

The fund's core holdings typically include U.S. Treasury and government agency securities, corporate bonds, and mortgage-backed and other securitized debt. AB's fixed income team uses research-driven security selection and sector allocation decisions, along with management of interest-rate exposure, in an attempt to add value relative to the broad U.S. investment-grade bond market.

As a core bond strategy, the fund is designed to serve as a foundational fixed income holding rather than a specialized or high-yield allocation.
