WisdomTree Bianco Fixed Income Total Return Fund (WTBN) is an exchange-traded fund that seeks to track the price and yield performance, before fees and expenses, of the Bianco Research Fixed Income Total Return Index. The fund employs a fund-of-funds structure, providing investors with a strategic fixed income portfolio driven by macro and fundamental factors from Bianco Research; key holdings include iShares MBS ETF, iShares 3-7 Year Treasury Bond ETF, iShares 7-10 Year Treasury Bond ETF, Vanguard Short-Term Corporate Bond Index Fund ETF Shares, and Schwab Short-Term U.S. Treasury ETF, representing approximately 76% of the portfolio with allocations to U.S. bonds (91%), non-U.S. bonds (8%), and cash (1%). It focuses on mid credit quality and moderate interest-rate sensitivity within the intermediate core bond category, offering exposure to government bonds, agency mortgage-backed securities, corporate bonds, and cash equivalents.
Launched on December 18, 2023, and domiciled in the United States with shares listed on Nasdaq, WTBN is managed by a team including Marlene Walker-Smith, David France, Todd Frysinger, Vlasta Sheremeta, and Michael Stoll, all starting from inception; the fund maintains total net assets of approximately $79 million, a net expense ratio of 0.59%, an effective duration of 5.03 years, and an average yield to maturity of 4.58% as of mid-2025.
In the first half of 2025, the underlying Bianco Research Fixed Income Total Return Index outperformed the Bloomberg U.S. Aggregate Index by 39 basis points, ranking in the 26th percentile among core bond funds, supported by tactical duration shifts and emerging markets exposure. WisdomTree, the fund's sponsor, completed the acquisition of Ceres Partners in October 2025, marking its entry into private asset markets with a focus on U.S. farmland investments to expand beyond exchange-traded products. The fund remains available primarily to U.S. investors through daily pricing and trading.
