ARR Investment Partners

What ARR Investment Partners does

ARR Investment Partners is a London-based investment boutique founded in 2015 by Christian Putz, specialising in a global equity long/short "quantamental" strategy designed for professional investors. The firm targets asymmetric risk-reward opportunities through both long and short positions, with an explicit objective of preserving capital during market downturns while delivering attractive returns during rallies, using sector/index ETFs and futures for top-down risk management and a strict stop-loss discipline.

The firm's core technology is PARIS (Portfolio Analysis and Risk Integration System), a proprietary portfolio and risk management system operating as a six-phase loop — backtesting, idea screening and generation, in-depth analysis, implementation and position sizing, continuous monitoring and risk management, and post-trade analysis. PARIS screens a universe of over 7,000 liquid stocks daily and maps candidates to four defined patterns: Rebound, Dynamic Profit Growth, Bubble, and Structural Losers. The team includes the founder/PM, a co-sourced COO with hedge fund ODD and prime brokerage experience, quantitative analysts with AI and reinforcement learning backgrounds, and a dedicated investor relations function.

ARR's business model is investment advisory and fund management. After building a 5+ year track record via Separately Managed Accounts, the firm launched its first Cayman-domiciled global long/short equity fund in February 2026. Distribution is direct institutional sales to professional clients, family offices, and high-net-worth investors, with regulatory coverage provided through FCA-authorised and SEC-registered sponsor Eschler Asset Management LLP. ARR is privately held, founder-controlled, has not raised external funding, and has not disclosed AUM or revenue.

Revenue model

1. Investment Advisory and Fund Management: ARR generates revenue through investment advisory fees and fund management charges associated with their global equity long/short strategy. The firm transitioned from a 5+ year SMA (Separately Managed Account) track record to launching a Cayman fund structure in February 2026, suggesting a move toward traditional hedge fund fee structures including management fees and performance/performance fees.

Expansion highlights4 records

Broad incumbents

• Viking Global Investors: Major global long/short equity hedge fund. Comparable strategy but operates at multi-tens-of-billions AUM and competes with ARR only at the larger end of the institutional allocator pool.
• Greenlight Capital: Established US long/short equity hedge fund (David Einhorn). Comparable product mandate but materially larger AUM and longer institutional track record than ARR.
• Man Group: Listed UK alternative asset manager (> $100B AUM) where Christian Putz began his career in 2006. Comparable only as a long-term reference point — Man is a multi-strategy quantitative and discretionary platform, orders of magnitude larger than ARR.
• Coatue Management: Large technology-tilted long/short equity manager. Comparable global long/short mandate and quantamental roots, but at vastly greater scale than ARR.

Direct peers

• Indus Capital Partners: Global long/short equity hedge fund manager. Theron De Ris, ARR's regulatory/compliance lead and CEO of parent Eschler, was previously a senior research analyst at Indus, and the firm's mandate, scale, and style closely overlap with ARR's strategy.
• Egerton Capital Partners: London-based long/short equity hedge fund manager targeting institutional investors. Directly comparable as a UK-domiciled, equity-focused, fundamentally driven boutique competing for the same family office and institutional allocator mandates.
• Polar Capital: London-listed asset manager running specialist long/short equity funds. Comparable as a UK-based equity alternatives boutique, though distributed through a fund (UCITS) wrapper rather than a Cayman hedge fund.
• Kazimir Partners: London-based long/short equity manager previously run by Christian Putz before he founded ARR. Highly comparable given shared DNA — same portfolio manager, same Eastern European / global equity focus, and similar boutique scale.
• Cadian Capital Management: US-based long/short equity manager with a quantamental tilt. Comparable given similar systematic-plus-fundamental approach and small-team boutique structure targeting institutional capital.
• Lansdowne Partners: One of the largest UK-based long/short equity hedge fund managers, founded by Paul Ruddock. Comparable in product (global long/short equity) and target client base, though at much greater scale.
