Market inefficiencies create opportunities for active managers. We believe there are more mispriced companies in small cap growth than in other equity markets, and we have developed an approach that allows us to capitalize consistently when we find them.

Inefficiencies in Small Cap Growth = Opportunity

Active managers focus on identifying stocks that have underappreciated growth prospects relative to their current price. Because markets are not perfectly efficient, mispricing can occur when there is a fundamental misunderstanding about a company. The small cap market is especially prone to mispricing. 

An Emerging Landscape

Many smaller companies operate in rapidly evolving markets that are giving rise to new industries or market segments. Additionally, these companies may have relatively short track records as public companies, creating skepticism about their growth trajectories. Think about Amazon in its early days when people did not understand how book sales and broader retail categories could be revolutionized online, displacing individual stores by centralizing warehousing and distribution. This type of ambiguity creates an opportunity to use in-depth research to identify the small subset of companies that are positioned to succeed over time.

Limited Analyst Coverage

Additionally, the small cap market lacks in-depth analyst coverage. Analysts tend to focus their attention on larger companies, which are more widely known and have a larger impact on the market, as illustrated in the chart below. 

Source: FactSet. Data as of June 2023. Large, mid, and small cap indexes are S&P 500, S&P MidCap 400, and S&P SmallCap 600, respectively. 

When you couple the market inefficiencies created by both the potential mystery around smaller companies and lower analyst coverage, experienced investors can add value through disciplined fundamental research. In his book, Pioneering Portfolio Management, former Yale University Chief Investment Officer David Swensen wrote:

Because Wall Street finds following smaller companies far less profitable, in terms of both day-to-day trading opportunities and occasional investment banking transactions, investors face the prospect of uncovering some interesting, mispriced investment opportunities. Although success demands hard work, small capitalization equity managers with an edge have a reasonable shot at generating attractive relative returns.  

Successfully Navigating the Small Cap Growth Market

Not all small cap companies will be able to grow and create shareholder value. It is critical to deploy a disciplined approach to identify those companies that can deliver sustainable growth over a multi-year horizon. Looking at the iShares Russell 2000 Growth ETF, nearly 13% of companies are unprofitable based on 2024 projected EBITDA. Additionally, the fourth quarter 2023 revenue growth rate for the median company was 7.4%. A passive approach can leave investors unnecessarily exposed to unprofitable and lower-growth companies.

We have found that focusing on a high-conviction portfolio of carefully selected businesses has allowed us to deliver strong results over time. Companies in our portfolio must meet our standard of quality, growth, and valuation. 


Because the small cap market includes many unproven and unprofitable companies, it is critical to focus on quality businesses. We define “quality” as companies with the following four characteristics: (1) a distinct proprietary advantage; (2) a leading position in the industry; (3) potential for margin expansion; and (4) the presence of a strong management team.

Through our in-depth fundamental research, we identify a select group of quality companies and generally avoid unprofitable and/or highly levered businesses. Our San Francisco location gives us the opportunity to perform ground-floor research with many of our portfolio companies and their competitors, as well as meet with management teams frequently.

Secular Growth

We are also committed to finding companies that are experiencing durable secular growth, as opposed to cyclical businesses that are simply benefitting from a strengthening economy. In other words, we are looking for companies that operate in a sector or industry that is undergoing a structural transformation, as this generally translates into an expanding customer base as well as pricing power. Historically, we have found that secular growth drives sustainable increases in both customer demand and revenue growth.

Moreover, secular growth usually marks a permanent shift in purchasing patterns. Sometimes it is because an older, inferior product is replaced by a better one (e.g., flip phones -> smart phones), and sometimes it is because something entirely new comes along (e.g., cloud computing, artificial intelligence). We focus on smaller companies with the innovative DNA to deliver superior value to customers. By contrast, incumbents, which are frequently larger companies, can get caught off-guard. As Alphabet’s CEO recently admitted, “scale isn’t always good for you since it makes it harder to “move fast [and] maintain a culture of risk-taking.” He added that “counter-intuitively … the more successful things are, the more risk-averse people become.”

Our portfolio is built around companies that can deliver durable increases in demand, so it has maintained much higher revenue growth than the index.

Buying at the right time is nearly as important as buying the right companies. Because of their distinctive growth/quality characteristics, the companies in our portfolio tend to trade at premiums compared to many names in the index, which have lower growth and/or profits. We are patient investors that wait for appropriate entry points. In selecting investments, we utilize an absolute valuation discipline – each new position must have 100% upside potential based on our five-year earnings model using an industry appropriate P/E ratio of no more than 30x, and we generally trim when the upside falls to 50% or lower.

Final Thoughts

Identifying and exploiting mispricing opportunities is always challenging, but it is less so in an inefficient market like small cap growth, which contains many relatively unknown companies. This allows us to conduct our own due diligence and formulate a differentiated view, which can lead to substantial upside. 

Using a combination of quality, growth, and valuation, we have established a repeatable method of finding these opportunities to drive long-term returns. This disciplined approach has led to outperformance versus the Russell 2000 Growth since the inception of the fund.

Current performance of the Fund may be higher or lower than the performance quoted. Performance data current to the most recent month end may be obtained by calling shareholder services toll free at (866) 236-0050. Performance prior to December 1, 2016 is that of another investment vehicle (the “Predecessor Fund”) before the commencement of the Fund’s operations. The Predecessor Fund was converted into the Fund on November 30, 2016. The Predecessor Fund’s performance shown includes the deduction of the Predecessor Fund’s actual operating expenses. In addition, the Predecessor Fund’s performance shown has been recalculated using the management fee that applies to the Fund, which has the effect of reducing the Predecessor Fund’s performance. The Predecessor Fund was not a registered mutual fund and so was not subject to the same operating expenses or investment and tax restrictions as the Fund. If it had been, the Predecessor Fund’s performance may have been lower.

The Russell 2000 Growth Index (Russell 2000G) is a market-capitalization-weighted index representing the small cap growth segment of U.S. equities.

The Fund’s portfolio has been compared to the iShares Russell 2000 Growth ETF as we believe it is representative of the Russell 2000 Growth index on an aggregate basis and it is one of the largest ETFs for the Russell 2000 Growth Index. The iShares Russell 2000 Growth ETF seeks to track the investment results of an index composed of small-capitalization U.S. equities that exhibit growth characteristics whereas OSTGX seeks long-term capital appreciation by primarily investing in companies that the Osterweis Capital Management investment team believes are likely to experience strong revenue growth and rising profitability. Investing in the ETF involves the risk of investing in small cap companies that may be less stable and more volatile. The expense ratio for the ETF 0.23% as of August 1, 2023. An ETF, or exchange-traded fund, is a marketable security that tracks an index, a commodity, bonds, or a basket of assets like an index fund. Unlike mutual funds, an ETF trades like a common stock on a stock exchange. ETFs are generally passively managed and track an index while mutual funds may be actively managed and have various investment objectives. ETFs may have lower fees than mutual funds. ETFs may be traded by investors throughout the day while mutual funds are only traded once per day. ETFs maybe be more tax efficient than mutual funds.
