iShares ESG Advanced High Yield Corporate Bond ETF (HYXF) is an exchange-traded fund that seeks to track the investment results of the Bloomberg MSCI US High Yield Choice ESG Screened Index, composed of U.S. dollar-denominated, high yield corporate bonds issued by companies with favorable environmental, social, and governance (ESG) ratings as determined by the index provider, while applying screens to exclude issuers involved in controversial activities. The ETF provides exposure to a diversified portfolio of below-investment-grade corporate bonds across various sectors including communications, healthcare, and consumer services; top holdings include securities from issuers such as TransDigm Inc., OneMain Finance Corp., CSC Holdings LLC, Iron Mountain Inc., and Hilton Domestic Operating Company Inc.; it emphasizes USD-denominated fixed income instruments with a focus on credit quality in the low range and limited interest-rate sensitivity. Launched on June 14, 2016 and managed by BlackRock, Inc., the fund is domiciled in the United States with headquarters aligned to BlackRock's operations in New York; it serves institutional and retail investors seeking high yield income with ESG integration, maintaining total net assets of approximately $188 million and an expense ratio of 0.35%. In recent developments, portfolio management saw the addition of Jonathan Graves as a senior portfolio manager effective in 2025, alongside prior updates including Marcus Tom, reflecting BlackRock's enhancements to fixed income oversight across its iShares funds. The ETF continues to align with rising sustainable investing trends, evidenced by its 6.51% dividend yield and stable performance amid high yield market dynamics, with no reported acquisitions, partnerships, or major strategic shifts in the last 1-2 years.
