ION Asset Management

Jonathan Half serves as Chief Executive Officer and is a co-founder of the firm, which he established in 2006. He leads the investment committee alongside a compact team of analysts and portfolio managers based in Herzliya, Israel. The firm's decision-making is concentrated and research-driven, following a fundamental long-short equity and credit framework.

ION is structured as an asset manager operating hedge fund strategies, not a family office. The firm manages capital on behalf of external institutional investors and family offices through pooled vehicles. It does not publicly identify a single wealth source or family behind its founding capital.

ION invests directly in public equities and credit instruments rather than making commitments to external private funds. The firm runs concentrated portfolios where each position is the result of internal fundamental research. It does not operate as a fund-of-funds or an LP in external managers.

ION has not published a formal exclusion list, but its disclosed focus on technology, healthcare, and consumer names suggests it steers away from capital-intensive sectors like heavy industrials, energy extraction, and commoditized real estate where its research edge is less applicable. The firm concentrates capital where it can model earnings and event catalysts with specificity.

ION is independent and not affiliated with any larger Israeli financial group, bank, or family office. It does not share ownership, back-office infrastructure, or capital-raising platforms with other named Israeli managers. Its strategy and legal structure are distinct and self-contained.

While based in Israel, ION deploys capital globally, with a primary focus on North America and Europe, and selective exposure to Asia. The firm is not a local-market specialist — it uses Israel as a talent and analytical base to invest across developed and select emerging-market exchanges.

ION does not publicly disclose a current AUM figure. Institutional database estimates and press reports do not carry a verified recent number. Allocators interested in the firm typically obtain sizing and capacity data through direct due-diligence conversations rather than public filings.
