About Us
Integrity. Performance.
With nearly 25 years of experience, Cygnet Capital focuses on serving high-net-worth individuals, institutions, professional investors, and money managers on ASX-listed, micro-cap investment opportunities.
Founding Directors Jonathan Rosham and Darien Jagger bring over 50 years of combined experience with small and micro-cap companies. Our approach is capital appreciation through well-researched investment opportunities rather than fee-driven product distribution.
We align our interests with those of our clients through equity investments and performance-based remuneration, ensuring mutual alignment and a strong foundation for success for all stakeholders.
At Cygnet Capital, we specialise in providing recommendations on individual stocks. Our research-focused and disciplined investment selection criteria are aimed at providing investments that can exhibit significant capital growth. Our portfolio and advisory clients own their investments directly in their own, personalised accounts, rather than owning units in a managed fund.
Our Approach
Our “stock picking” approach is exclusively available to qualified, high-net-worth, sophisticated, institutional and professional investors.
Our investment universe is primarily ASX-listed companies under $300 million in market capitalisation. Cygnet Capital has made this universe of stocks its niche. We believe that the low levels of research coverage and liquidity of the shares in some companies can cause significant mispricing compared to the broader ASX.
The extended Cygnet Capital team are constantly researching, assessing and sourcing opportunities. Our recommendations are driven by in-house analysts, allowing us to identify undervalued companies, emerging potential market trends and promising macro-economic opportunities.
We understand the importance of clear and consistent communication, and we strive to keep our clients informed about their investments through regular updates and reports. Our goal is to foster long-term relationships built on trust and mutual success.
We employ a diverse sector strategy that spans resources, technology, energy, and health sciences. Notably, we avoid investing in property or real estate companies. Our broad mandate enables us to evaluate and invest in opportunities based on their individual merits. Our advisory method is collaborative.
We charge our portfolio and advisory clients a fee per transaction, rather a management fee and performance incentives on assets under management.
