Congratulations to the following team members on their well-deserved promotions. On July 1st, we also welcomed two new members to the Research Team.
Investors are historically wary of small cap biopharma given the need for technical knowledge and the potential for high volatility, concerns that are clearly validated by market data. In this paper we detail our approach for navigating biopharma with technical expertise and through a quality growth lens that has resulted in a successful approach over the past decade.
In the second quarter, there were double-digit returns for equities as global economic activity measures lifted into expansion territory. However, there were many tremors across the economic landscape, with Washington, D.C. at the epicenter.
Equities seemed unfazed as the U.S.’s Russell 3000® Index rose 11%, keeping pace with the 12% returns for the MSCI EAFE and MSCI Emerging Markets Indexes.
General — We saw companies across most areas either scrap or significantly reduced forward guidance. As they wait to see how near-term results fare in this environment, we believe some have lowered expectations to levels that can be surpassed in future quarters.
Consumer — With so many consumer goods potentially subject to tariffs, measures of confidence and sentiment remained at trough levels. Some customers advanced their purchases ahead of expected price hikes. Companies with better balance sheets increased their inventories during tariff pauses, which should provide them with opportunities for greater market share later in 2025.
Financials — Although M&A activity began unexpectedly slowly this year, there were early signs it was accelerating. As equity market levels climbed following initial recession fears, capital markets and trading firms recovered sharply with continued growth in fundamentals.
Health Care — Reduced Medicaid spending weighed on volume levels and growth across the sector. Changes at the FDA slowed regulatory approvals, which combined with the Trump administration’s rhetoric for lower drug prices and onshore production, have dampened enthusiasm for the biopharma industry.
Industrials — Many companies are understandably conservative with their outlooks as tariff levies are quickly announced and rescinded. That favored longer cycle secular end markets—such as aerospace & defense, datacenter related, and infrastructure—compared to the short cycle cyclical areas of transportation or consumer related. Though if the Federal Reserve becomes more dovish, the recent industrial laggards could return to favor later in 2025.
Information Technology — As with other segments, anticipation of higher prices from tariffs led to a short-term surge of orders across the semiconductor industry. Offsetting that was the rebound in spending for all things AI related, which had been weak in the first quarter following DeepSeek’s emergence. One notable confirming data point for the AI megatrend was Ford Motor’s CEO predicting that “artificial intelligence is going to replace literally half of all white-collar workers in the U.S.”
Health care, particularly biopharma, stands as one of the most dynamically innovative sectors in the global economy, serving as a beacon of scientific advancement that continuously reshapes the landscape of medical treatment and patient care. Since the groundbreaking Human Genome Project published its first working draft in 2000 and achieved its monumental completion in 2003, we have witnessed an extraordinary acceleration in biopharma innovation that has fundamentally transformed the practice of medicine.
Investors are historically wary of small cap biopharma given the need for technical knowledge and the potential for high volatility, concerns that are certainly validated by market data. As illustrated in the accompanying chart¹ showing monthly returns from 2015-2024, the XBI index (an equal-weighted S&P biotech ETF) demonstrates significantly higher volatility compared to the Russell 2000® Growth Index (RUO), with annualized volatility of 29.55% versus 21.16% respectively. This 40% higher volatility in XBI is statistically significant and highlights the notable risk that many investors face. Since XBI is an equalweighted index that includes larger cap biotech companies, small cap biotech investments would be expected to exhibit even greater volatility than these already elevated levels. This combination of technical complexity in evaluating drug development pipelines, regulatory risks, and the extreme price volatility evident in the data explains why many investors approach the sector with considerable caution, despite its potential for outsized returns during favorable periods.

Despite the inherent risks and volatility that characterize small cap biopharma investments, several compelling structural factors make the industry increasingly attractive for long-term investors. The convergence of powerful demographic tailwinds, including a rapidly aging population and rising obesity epidemic, coupled with health care expenditures consistently outpacing GDP growth, creates sustained demand for innovative therapeutic solutions that biopharma companies are uniquely positioned to deliver.
Furthermore, the high cost of drug development, long regulated development processes, highly regulated supply chains, and intellectual property patent protection provide significant barriers to entry. In addition, novel green field market opportunities such as first-in-class therapies in new disease markets enjoy substantial and quantifiable advantages that create lasting competitive moats. Over the last 5 years, small cap biopharma has been a primary source of innovation with ~65% market share² for new drug launches.
As quality growth managers, we employ a rigorous investment process that has been refined over the past 20 years. It focuses on three core pillars for identifying companies: distinct, sustainable competitive advantages, quality management teams, and strong consistent growth profiles. Within the small cap biopharma universe, where the developmental, high-risk, and cashburning nature of these companies scares many fundamental growth managers away from the sub-sector, we have applied a rigid investment process to find companies that fit our investment criteria. This process centers on identifying companies developing first-in-class therapeutics that represent true greenfield opportunities in areas of significant unmet medical needs. We look for rare disease opportunities and targeted therapeutics that address specific patient populations with precision, and novel drug targets in large disease areas where traditional approaches have failed. We place particular emphasis on management quality given the complex developmental pathways and regulatory interactions inherent in drug development, recognizing that successful drug approval requires exceptional leadership with a clear vision for navigating the intricate regulatory landscape from preclinical studies through clinical trials to FDA approval.
Small cap biopharma investing presents a distinctive risk-reward proposition shaped by the inherently challenging nature of drug development, where the overall success rate² from initial discovery to market approval hovers around just 8%. We focus our attention on companies that have successfully navigated past the proof-of-concept stage, particularly those with Phase II data in hand. Phase II represents the most critical inflection point in drug development, where success rates² plummet to just 30% thereby supporting our strategic approach. By concentrating on post-Phase II opportunities, we can avoid the highest attrition phase while still capturing significant upside potential, as companies with validated proof-of-concept data face substantially improved odds of 57% and 95% success rates² in Phase III and regulatory approval, respectively.

As quality growth managers we have maintained a consistent underweight to biopharma, due in part to our intentional avoidance of some of the more speculative early stage, pre-commercial biopharma companies that populate the index and possess significant levels of binary risk. Thus, we strategically tilt our portfolio weighting 3 to commercial companies and maintain a more pronounced underweight to pre-commercial biopharma (~-400bps) vs commercial biopharma (~-300bps).

We believe our strategic approach to biopharma investing has been successful, generating substantial alpha in a risk disciplined manner while maintaining significant underweight relative to the benchmark. From 2015 through June 2025, our biopharma positioning⁴ contributed 107 bps of annualized gross outperformance, while maintaining an average underweight of approximately 680 bps. We believe this performance demonstrates the effectiveness of our selective stock-picking approach, focusing on quality companies with strong fundamentals rather than simply matching benchmark weights or taking a basket approach. Additionally, our strategy 5 has benefited from persistent merger and acquisition activity within the sector, as approximately 15% of our unique biopharma investments have been acquired by larger companies, providing a meaningful tailwind to our returns. This M&A activity validates our ability to identify attractive takeover targets and underscores the value creation potential inherent in our carefully curated biopharma holdings, further contributing to consistent outperformance despite an underweight positioning.

This insight paper serves as just a glimpse into the longer-form and highly detailed Navigating Small Cap Biopharma white paper that we are pleased to provide upon request.

It’s worth reiterating that the way the benchmark is constructed, and growth and value are split, are based on definitions that haven’t changed in decades. As our team evaluates our holdings and seeks out new ideas, we have the freedom to cast a wider net across the landscape of companies, often finding those that don’t fit into the traditional growth or value boxes. These ideas are often overlooked by managers looking solely at the big index weights or the popular theme of the day.
One source of new ideas comes from a reexamination of companies undergoing potentially positive change(s) that the market is not fully appreciating (e.g. upgraded senior management, enhanced strategies/business models, improvements in their end markets). We believe we have the important advantage of sourcing ideas as they “graduate” from the dedicated Small Cap strategies we manage. These names are covered by the same investment team, so there is familiarity and institutional knowledge of these businesses when they have grown to the thresholds to be eligible for Mid Cap. When reviewing our Mid Cap Growth portfolio today, over 20% of current positions were previously held in our Small Cap strategy and are graduates of the selection process. Elevating these small cap names is one manner that refreshes our strategy and stays true to the essence of Mid Caps.
Passive investing in Russell Midcap index strategies increasingly means losing access to the true breadth and depth of companies across the Mid Cap market capitalization range. We argue that our active management and rigorous stock selection helps to provide a more authentic representation of Mid Cap exposure, allowing us to uncover attractive opportunities overlooked by the benchmark. As the index has become significantly larger and more concentrated, the need for this active approach is growing. Since these indexes are the default standard for Mid Cap allocations, their inherent structural risks are often disregarded; therefore, relying on the index alone for distinct Mid Cap exposure may prove insufficient. In other words, if you’re looking for exposure to the Mid Cap space and believe you’re getting it from allocating to the index, think again.
