A Model-Driven Biotechnology Portfolio
That Uses Systematic Investing
and Combines...


Our system sifts through biotech companies, analyzing them on a variety of criteria, to short list stocks that can potentially deliver strong gains. The pursuit of returns also increases volatility. After various iterations, we arrive at a ranked list of stocks that are then used in combination with portfolio rules to construct the model portfolio. Discipline is important in pursuing an investing system and we stick to it.


Wealth-building requires Patience. A system needs time to work and deliver results. Patience is required when following any investment strategy or system that you have confidence in. We judge our system over the long-term (3+ years) and not fixate on short-term monthly performance. Just as a plant takes time to grow into a tree, so does a portfolio as it compounds and grows its gains over the years.


Through a combination of Prudence and Patience, the system is able to achieve consistency of Performance. Small caps are a market segment of high promise and high volatility. The disciplined approach allows the portfolio to be positioned in some of the strongest names. Even though there are ups-and-downs, the system has historically delivered strong performance well in-excess of benchmark returns.
