Introduction
At Ironwood Investment Management, LLC, we believe that diligence is one of the defining factors that sets thoughtful investors apart in small-cap investing. While data analysis and financial modeling are vital, we find that the most valuable insights often come from seeing the businesses we invest in up close: meeting leadership teams, touring facilities, and understanding operations firsthand. This approach provides us with a deeper appreciation for how companies create value, navigate challenges, and position themselves for potential growth.¹
Why Diligence Matters in Small-Cap Investing
Small-cap companies often operate under the radar. They can be early in their growth trajectories or focused on specialized markets that require a nuanced understanding to evaluate properly. Because their stories are less told, investors cannot rely solely on financial statements or quarterly reports to assess their long-term potential.
Diligence allows us to bridge that gap. By engaging directly with management and observing operations firsthand, we gain insight into a company’s strategy, culture, and execution capabilities. This approach helps us form an informed perspective about whether the business is positioned to capitalize on potential opportunities in its sector.²
Through this disciplined process, we strive to identify companies that not only demonstrate strong fundamentals but also exhibit leadership and innovation aligned with sustainable, long-term value creation.
Research in Action: Visiting Aspen Aerogels
A recent visit to Aspen Aerogels, headquartered in Massachusetts, exemplified the importance of this research-driven approach. Our team had the opportunity to meet with Neal Baranosky (Investor Relations), Donald Young (President & CEO), and Grant Thoele (CFO & Treasurer). Speaking directly with company leadership provided meaningful insight into how Aspen Aerogels is advancing its strategy and operations.
The visit included a tour of the company’s manufacturing facilities, offering firsthand visibility into its production capabilities and technology platform. Seeing the operations in person allowed us to better understand how the Aerogel Technology Platform® supports multiple applications, from energy infrastructure to electric vehicles.³
Aspen Aerogels’ innovation in electrification and sustainability aligns with major trends shaping the global economy, including clean energy and resource efficiency. While financial reports can illustrate metrics and forecasts, being on-site deepens our perspective on execution quality, product differentiation, and management vision.
This type of diligence reinforces our belief that long-term investing success is driven by understanding the people and processes behind the numbers.
A Disciplined Approach Rooted in Research
At Ironwood, the investment philosophy of our Small Cap Core Strategy (SCC) has always centered on discipline and research. We take a bottom-up, fundamental approach, carefully analyzing each company’s financial health, management quality, and strategic positioning. Site visits, management interviews, and on-the-ground engagement are extensions of that research discipline.
By combining quantitative analysis with qualitative understanding, we aim to recognize businesses with strong governance, innovative capacity, and sound financial frameworks. We believe this multi-dimensional approach allows us to identify potential opportunities that might be overlooked by investors relying solely on secondary data.
The diligence-driven process of our SCC strategy also provides an opportunity to evaluate environmental, social, and governance (ESG) considerations firsthand. Observing how a company manages sustainability initiatives, employee safety, and community engagement helps us gauge long-term resilience and alignment with broader market themes.
Connecting Diligence to Performance Track Record
While we avoid making forward-looking predictions, we believe that consistent diligence has contributed to Ironwood’s long-term performance track record. Our emphasis on engagement and firsthand evaluation enables us to make investment decisions grounded in conviction and understanding.⁴
Over time, this consistency builds a foundation for clients who value transparency and thoughtful portfolio construction. Diligence also provides context during periods of volatility: when markets fluctuate, our familiarity with each company’s strategy and leadership helps us maintain perspective and make informed adjustments where necessary.
In our experience, there is no substitute for being there, meeting the people behind the business, understanding how they think about risk and opportunity, and seeing how their strategic plans translate into real-world action.
