About ARR Investment Partners

ARR is a London-based investment boutique specialising in a global long/short equity strategy for professional investors. We have delivered top-decile performance, achieving ~320% net returns since inception in 2015, with strong outperformance during market downturns. Navigating bear markets is our core strength and sets us apart from other great funds. For example, in the recent sell-off in March/April, we have generated strong positive returns, and we had our best year ever in 2022 (+46,8%) when global equity and bond markets crashed.

Given our strong returns and negative correlation in market sell-offs, our vision is to be part of every investment portfolio of every investor globally, as a great complement to widely used ETFs. We want our investors to smile when they look at their investment returns and sleep well in market panics.

In 2024, ARR Investment Partners won the "With Intelligence HFM European Performance Awards" in the category "Global Equity Under $500m", and ARR has been shortlisted four times for best European hedge fund in the "Global L/S Equity" category in the past five years.

We are a nimble, entrepreneurial team managing under $100 million, with a focus on family offices, high-net-worth individuals and multi-strategy funds. Our "quantamental" approach blends cutting-edge quantitative screening with rigorous bottom-up fundamental analysis, powered by our proprietary Portfolio and Risk Investment System (PARIS).

This is an exciting time to join ARR as we prepare to launch a Cayman fund by February 2026, offering the opportunity to play an integral role in this significant milestone.

The Role

We are seeking a passionate, analytical, and ambitious Junior Portfolio Manager to join our growing team at a pivotal moment in our firm's evolution. In this role, you will be deeply involved in every stage of the investment process-from idea generation and research to portfolio construction, trade execution, and ongoing risk management. Working closely with senior team members, you will help identify and evaluate global investment opportunities, leveraging both quantitative models and fundamental analysis. Your responsibilities will include building and maintaining a diversified long-short equity portfolio, executing trades across multiple markets, and applying disciplined risk controls to preserve capital and optimise returns.

As a key member of our team, you will have the opportunity to contribute your own investment ideas, collaborate on strategy, and take on increasing responsibility as you demonstrate your capabilities. You will also play an integral role in the launch of our new Cayman fund, gaining exposure to fund structuring and operational best practices. This is an ideal position for someone who thrives in a dynamic, entrepreneurial environment, is eager to learn, and is motivated to make a tangible impact on both investment performance and the future growth of the firm.

What We're Looking For

• 2-3 years' experience as a long/short equity portfolio manager, or 3-10 years as an analyst/trader with a proven track record.
• Alternatively, experience as a prop trader or running a personal account strategy with demonstrable results.
• Strong analytical skills and a deep understanding of global markets and macro developments.
• Demonstrated ability to construct portfolios with high returns and low drawdowns (must be able to prove risk management approach, e.g., keeping peak-to-trough drawdown under 10%).
• Willingness to execute trades and, if not already certified, commitment to obtain necessary qualifications.
• Ideally, experience with short-selling.

What Makes You a Great Fit

• You share our investment philosophy: trading-oriented, using both fundamental and technical analysis, and open to multiple schools of thought (value, momentum, etc.).
• You have the courage to act decisively when conviction is high, but always with rigorous risk management.
• Passion for financial markets, single stock picking and global macro analysis
• You have the mental flexibility to change your investment thesis/position in the face of new evidence
• We value energy, curiosity, and a "can-do" attitude.
• You want to be the best globally, at least in one area of expertise

What You'll Do:

• Contribute to portfolio construction and trade execution across global equities (Europe, USA, Emerging Markets).
• Apply strict risk management, including stop-losses and exposure controls.
• Use our proprietary PARIS system for screening, analytics, and real-time monitoring.
• Collaborate with the analyst team to generate and evaluate investment ideas.

Our Process & Philosophy:

• We focus on asymmetric risk-reward opportunities and adapt net exposure based on market conditions.
• Our portfolios are diversified (20-40 positions), liquid, and managed with a net long bias.
• We use a combination of quantitative ranking and qualitative analysis, with technical analysis to optimise the hit ratio and risk reward ratio.
• We emphasise capital preservation and downside protection.

What We Offer:

• The opportunity to join a high-performing investment boutique with a strong track record and reputation.
• A collaborative and entrepreneurial work environment where your contributions will have a direct impact.
• Competitive compensation package, including performance-based incentives.
• The chance to work closely with a talented and driven team, as well as exposure to leading investors and industry professionals.
• The opportunity to be part of the launch of our Cayman fund, a significant and exciting milestone for ARR.
• A strong growth trajectory with several product launches ahead.
