Rosenberg Capital

Rosenberg Capital seeks to generate superior long-term, risk-adjusted returns relative to global equity benchmarks over a full market cycle.

The fund aims to achieve this through a concentrated portfolio of high-conviction investments in structurally advantaged companies with the potential for sustained earnings growth and durable competitive positioning.

Our objective is not short-term outperformance, but disciplined capital compounding while minimising the risk of permanent capital loss.

Rosenberg Capital is a founder-led, concentrated long-only equity fund focused exclusively on U.S. public markets, the most liquid and opportunity-rich capital market in the world.

We run a concentrated, high-conviction portfolio. Capital is allocated to a limited number of businesses where we have strong fundamental conviction and thematic insight, rather than diversified for comfort. We believe true alpha is generated through depth of research, disciplined position sizing, and patience.

Our investment horizon is multi-year. We seek to partner with structurally advantaged companies and businesses exposed to powerful long-term themes, allowing compounding to work over time rather than reacting to short-term noise.

Alignment matters. The founders invest alongside clients, ensuring incentives are fully aligned toward long-term capital appreciation and prudent risk management.

Rosenberg Capital is built on the belief that concentration, not diversification, is the source of long-term alpha.

Every position begins with a research memo written before the first share is purchased. That memo defines the investment thesis, the thematic driver, the conditions that would invalidate it, and the exact price zones at which we will add or exit. Decisions are made in advance and held regardless of short-term price movement.

We do not react to markets. We prepare for them by combining fundamental analysis, thematic research, and disciplined portfolio construction.

The portfolio is intentionally concentrated, typically comprising 8 to 12 high-conviction positions. We believe meaningful outperformance requires focus rather than broad diversification.

Position sizing is driven by conviction, downside assessment, risk–reward asymmetry and the strength of each company’s competitive advantages, not by index weights or market averages. Core holdings represent our highest-confidence ideas, while smaller allocations may reflect emerging opportunities or investments with greater uncertainty.

Risk is managed at the portfolio level through disciplined exposure control, ongoing thesis validation, and continuous reassessment of valuation. We seek to avoid permanent capital impairment by emphasizing balance sheet strength, competitive durability, and appropriate entry price.

The result is a concentrated yet risk-aware portfolio designed to maximise long-term compounding while maintaining structural resilience.
