Their Investment Philosophy

"The pricing of microcap companies is inefficient relative to large listed companies, providing opportunities for excess returns relative to risk.
Research

In-depth fundamental research, both at the sector and company level, is essential in the microcap sector and is the cornerstone of our investment performance. We believe that fundamental research is more important than valuation techniques and we make investment decisions based on relative value against a peer group. Our strong commitment to research is evidenced by our highly experienced research team, comprehensive database and knowledge of the microcap sector compiled over the past decade.
Portfolio management

We seek to manage microcap portfolios in a way that:

* Is founded on structured fundamental investment analysis
* Makes full use of our team’s business and financial markets experience
* Is professionally and academically rigourous"
