What Wellesley Asset Management, Inc. does

Wellesley Asset Management, Inc. is a Portsmouth, New Hampshire-based registered investment advisor founded in 1991 by Greg Miller, specializing in actively managed convertible bond portfolios. The firm manages approximately $2 billion in convertible securities for high-net-worth and ultra-high-net-worth individuals, family offices, registered investment advisors, banks, wirehouses, pensions, and financial advisors nationwide. Core offerings include customized separately managed accounts (SMAs), mutual funds, private funds, and, as of March 2026, the Miller Convertible Total Return ETF (MCVT) listed on NYSE Arca. The firm also acquired Halbert Wealth Management in September 2025 to broaden its wealth-management footprint.

The investment approach is centered on convertible bonds, convertible arbitrage, alternative fixed income, liquid alternatives, hedge funds, and structured notes, marketed as a structural alternative to traditional 60/40 allocations. Portfolio leadership is unusually deep for a boutique: Founder Greg Miller (35+ years), CIO David Clott (former founder of Aviva Investors' Global Convertible Bond Strategy and multiple convertible arbitrage hedge funds), and Senior PM James Buckham (30+ years across Deutsche Bank and Fidelity convertibles desks). Operations are supported by an executive team including President Dawn Baillie (ex-John Hancock/Manulife), COO Dennis Godin (ex-Fidelity/Vestmark), CCO/General Counsel Steven Rawlings (20-year SEC veteran), Head of Sales Jay Russo, and EVP Private Client Group Joseph M. Buscaino.

The business model is a percentage-of-AUM advisory fee on approximately $2 billion in managed assets, distributed through a Private Client Group, a registered-investment-advisor and wirehouse intermediary network, and the newly launched MCVT ETF. The firm is founder-owned and controlled (no disclosed funding rounds, institutional investors, or parent company), headquartered at 100 Market Street, Suite 300, Portsmouth, NH, with 11–50 employees.

Direct peers

• Calamos Asset Management: Calamos is one of the most established US convertible bond managers with a long-running mutual fund and ETF suite built around the same asset class. Like Wellesley, it targets HNW, RIA, and institutional clients with convertible and alternative income strategies, making it a closely comparable specialist peer.
• Advent Capital Management: Advent is a boutique convertibles and credit manager serving institutional and intermediary clients through convert, balanced, and arbitrage strategies. Its product mix and SMA/mutual fund structure directly parallel Wellesley's SMA convertible book and institutional focus.
• MainStay MacKay Convertible Fund: MainStay MacKay's convertibles franchise (within New York Life Investments) is one of the largest dedicated convertible strategies distributed via intermediaries. It competes with Wellesley in the same advisor and institutional channels with the same asset class.
• SPDR Bloomberg Convertible Securities ETF (CWB): CWB is the dominant passive convertible bond ETF and the most direct exchange-traded comparable to Wellesley's newly launched MCVT. It competes for the same ETF wallet in RIA and retail brokerage accounts.
• Zais Group: Zais Group is a boutique credit and convertibles specialist running institutional and intermediary strategies with a similar size and channel profile to Wellesley. It is a relevant specialty peer for convertible and structured credit mandates.

Broad incumbents

• Federated Hermes (Convertible Securities): Federated Hermes offers a convertible securities fund as part of a much broader fixed income and equity platform. It competes with Wellesley in intermediary channels but at greater scale and product breadth, making it a broad incumbent comparable.
• Allspring Global Investments (Convertible team): Allspring runs a dedicated convertible bond strategy within a large multi-affiliate fixed income platform. Like Federated Hermes, it competes head-to-head with Wellesley for intermediary and institutional convertible allocations but with broader scale.
• Fidelity Investments (Convertible Securities Fund): Fidelity offers a convertible securities fund within a massive retail and intermediary distribution platform. It is a broad incumbent competitor for convertible allocations sourced through Fidelity's captive RIA and brokerage channels.
• Virtus Investment Partners (convertible strategies): Virtus affiliates offer convertible and multi-sector credit strategies distributed through intermediary channels. Like other multi-affiliate platforms, it competes for the same advisor wallet as Wellesley but with a wider product shelf.

Emerging players

• Alerian convertibles ETFs: Alerian and other smaller convertible-focused ETF sponsors compete directly with MCVT in the exchange-traded convertible space, but with more limited AUM and distribution. They represent emerging peers in Wellesley's newest distribution channel.
