PropThink is a leading online destination for retail and institutional investors seeking actionable and independent analysis of publicly-traded, emerging growth companies in the healthcare sector. Our editorial team is comprised of individuals with a strong background in science, medicine and the business of successfully commercializing therapeutics, medical devices, diagnostics and healthcare services. Our ultimate objective is to leverage the knowledge and experience of our contributors to introduce our subscribers to profitable long and short investment opportunities in the healthcare sector.

Successfully trading and investing in development-stage healthcare companies is a difficult task. Over 90% of drugs that are tested in the laboratory never make it to market, and only a small portion of drug candidates that move into human testing will make it across the finish line – an approved and marketed product. Most of these small companies won’t have revenues for many years as they move through development, and will require huge capital investments along the way. This often results in repeat and highly dilutive equity financings for these companies, sometimes done on the backs of retail investors. Most biotechnology companies simply won’t succeed, and identifying the quality companies in this complicated landscape is no easy task.

We leverage a combined 50 years of experience in science, medicine, legal, regulatory affairs, finance, and operational industry experience to analyze companies at a highly technical level. This detailed analysis and due diligence process defines our editorial strategy and provides our subscribers with a high level of confidence in our research. There’s plenty of noise out there, which is why PropThink’s mandate is complete independence. We’re committed to providing a balanced view and believe that skepticism is a major prerequisite to investing in the healthcare sector.

At present, PropThink offers regular market coverage and periodic feature stories (called Insights), periodic Interviews with key opinion leaders and investors, as well as an actionable investing newsletter called PropThink Premium (see our Research).
