ALVA CAPITAL MANAGEMENT
Thomas Kempner and Hiram Moore's Alva Capital runs a concentrated long/short equity partnership focused on technology and healthcare from New York.
ALVA CAPITAL MANAGEMENT
Alva Capital Management was founded in 1997 by Thomas L. Kempner and J. Hiram Moore in New York. Kempner previously served as a general partner at Omega Advisors, while Moore's background traces to Tiger Management, embedding the firm with the analytical rigor of the Julian Robertson lineage. The firm operates as an employee-owned registered investment adviser. Alva runs a long/short equity strategy concentrated in technology, healthcare, and digital infrastructure. The portfolio typically holds 15–25 core names, with position sizing reflecting deep fundamental research rather than index-weight considerations. The firm invests across the market-cap spectrum in North America and developed Europe, with a public-equity track record spanning more than two decades. Alva has held positions in companies including Mastercard, Microsoft, and Salesforce over different market cycles. The firm maintains a deliberately lean team structure in New York, with the three named managing partners — Kempner, Moore, and David J. Wermuth — directly involved in research and portfolio construction. The firm does not operate adjacent credit vehicles, separate private funds, or a multi-family office arm. Recent regulatory filings indicate continued concentration in public technology and payments exposure. Alva's structural differentiator is its adherence to the Tiger Cub model of deep company-level research married with a partnership platform that does not scale headcount to chase asset growth. The firm has intentionally avoided product proliferation — no ETF launches, no expansion into private markets, and no sub-advisory relationships — preserving a single mandate across decades.

Frequently asked questions
Who runs investment decisions at Alva Capital Management?
Thomas L. Kempner, J. Hiram Moore, and David J. Wermuth are the managing partners listed on Alva's regulatory filings (per the firm's Form ADV). Investment decisions are made collectively by this three-person leadership group, consistent with the firm's partnership structure.
Is Alva structured as a hedge fund, a family office, or something else?
Alva Capital Management is an employee-owned registered investment adviser that manages a long/short equity partnership. It is not a family office — the firm manages external capital alongside partner capital in a commingled vehicle. It traces its lineage to the Tiger Cub network of hedge funds, given Moore's background at Tiger Management.
What is Alva's typical portfolio concentration and holding period?
Alva typically maintains a portfolio of 15–25 core positions, consistent with a high-conviction research model (per public record). The firm does not publish its holding periods, but its long/short equity mandate suggests multi-year time horizons for core long positions, in line with the Tiger Cub tradition of intensive company-level research.
Does Alva invest in private companies or only public equities?
Alva focuses on publicly traded equities. The firm's Form ADV and historical 13F filings reflect a public-markets mandate across technology, healthcare, and digital infrastructure. There is no record of an affiliated private-equity vehicle or venture-capital fund.
What is the Alva team's connection to Tiger Management?
J. Hiram Moore spent his early investment career at Tiger Management, Julian Robertson's legendary hedge fund (public record). This anchors Alva in the Tiger Cub lineage — a network of managers known for concentrated, research-intensive long/short equity strategies. Thomas Kempner's prior experience includes a general partner role at Omega Advisors.
