BlackRock Dynamic High Income Portfolio (BDHIX) is an open-end mutual fund managed by BlackRock Funds II that seeks to achieve high current income by tactically allocating assets across a diversified portfolio of non-traditional income sources, including equities, fixed income securities, equity-linked notes (ELNs), exchange-traded funds (ETFs), derivatives, and money market instruments. Core holdings encompass high yield corporate bond ETFs such as iShares Broad USD High Yield Corporate Bond ETF; dividend growth ETFs including iShares Core Dividend Growth ETF and iShares International Dividend Growth ETF; equity-linked notes on major stocks like NVIDIA Corp, Apple Inc, Microsoft Corp, and Meta Platforms Inc; collateralized loan obligations (CLOs) from issuers such as Benefit Street Partners CLO XXI Ltd and Neuberger Berman Loan Advisers CLO 34 Ltd; futures contracts on indices like E-mini S&P 500 and currency pairs; and liquidity funds like BlackRock Liquidity Funds - T-Fund, with allocations dynamically adjusted to capture income opportunities amid varying market conditions. The fund operates globally with exposure to U.S. and international markets, targeting institutional investors with a minimum initial investment of $2 million, and features a net expense ratio of 0.68%. Launched on November 3, 2014, and domiciled in the United States, it is headquartered alongside BlackRock Inc. in New York. As of late 2025, the fund maintains total net assets exceeding $1.3 billion, with portfolio managers Justin Christofel (since inception) and Alex Shingler (since 2015) overseeing its flexible multi-asset strategy benchmarked against a 50/50 blend of MSCI World High Dividend and Bloomberg High Yield indices. Recent quarterly commentaries highlight sustained performance amid volatility, including a 5.54% return for Q3 2024 (Institutional shares) and tactical shifts toward high-conviction income sources like ELNs and CLOs, though no major acquisitions, partnerships, funding rounds, or structural changes have been announced in the past 1-2 years.
