Some people move fast and chase the spotlight. Others take their time, study the facts, and build something that lasts. David Rewcastle is in that second group.
He is an experienced equity and fixed income analyst based in Darien, Connecticut. Over nearly twenty years, he has built a reputation for deep research and accurate stock picks. He began with a focus on energy and utilities and has spent the past five years covering the biotech sector.
David’s work has been recognized by the Wall Street Journal, Forbes, and the Financial Times. He has led panels at investment conferences and teaches economics at the University of New Haven. His background in Middle East studies, finance, and global economics provides him with a unique perspective on markets.
In this interview, we talked with David about how he got started, the lessons that shaped his approach, and what he plans to focus on next. You can explore more conversations like this in our finance section.
How did you get started in the industry?
“I started by studying what most people were not,” David says. “Petroleum economics and Middle East politics. That gave me an edge when it came time to understand how global markets really worked.”
He studied at the University of Calgary, then spent time learning Arabic and regional politics in Cairo and Damascus. Later, he earned graduate degrees from New York University, combining business and international studies.
“I did not plan to become a stock analyst,” he says. “But I wanted to understand how energy markets moved and how global events influenced financial outcomes.”
That curiosity led him into research roles focused on oilfield services and utilities. Over time, his work stood out for its accuracy and thoughtful approach.
“I focused on companies other people overlooked. I wanted to understand them from the ground up. That helped me make better recommendations and also gave me more confidence when things got volatile.”
What advice can you give future leaders in your industry?
“Stay curious,” David says. “That is the most important thing. You do not have to know everything. But you should always be learning.”
He encourages new analysts to focus on the basics. “Understand how a business makes money. Understand where it is vulnerable. Stay grounded in facts.”
He also discusses the importance of effective communication. “If you cannot explain your thinking clearly, it does not matter how smart you are. You need to help others see what you see.”
Teaching has helped him sharpen that skill. At the University of New Haven, David teaches economics with a focus on practical understanding. “Students want real-world knowledge. Not just theory. I try to connect the two.”
He reminds people that mistakes are part of the job. “You are going to get it wrong sometimes. The important thing is to figure out why and keep improving.”
What do you want to focus on over the next 10 years?
David is paying close attention to how biotech, energy, and technology are merging.
“These sectors are not isolated anymore,” he says. “Energy companies use data to improve performance. Biotech firms are driven by innovation that affects everything from supply chains to public health. It is all connected.”
He plans to continue covering biotech, especially where it overlaps with long-term value investing. You can explore this topic further in our technology section.
David is also passionate about education. “I want to spend more time helping young professionals find their voice and improve their thinking. We need more people who ask good questions and care about getting things right.”
He sees the next decade as a time of big challenges. “Climate change, shifting economies, geopolitical risks. You cannot predict it all, but you can prepare. That is where thoughtful research makes a difference.”
He continues to explore the impact of these shifts through his work at E3 Research Associates. “What excites me is finding clarity in complex times. That is what I enjoy most about this work.”
