Investment Philosophy

We believe that above-average returns can be achieved by owning a diversified group of small to medium-sized companies growing at a rate greater than the average company in the S&P 500.

  • We focus on revenue rather than market capitalization.
  • Our approach provides opportunities to hold individual securities as they grow from small to medium-sized businesses.
  • As long-term investors, we own our holdings considerably longer than the industry average, which has resulted in deep institutional knowledge of our investments, higher returns, lower turnover and greater tax efficiency.


Quality and Selectivity

  • We identify a proprietary universe of 100 companies based upon a consistent and proven research-driven process.
  • We follow companies closely, typically over a multi-year period, before committing to an investment.
  • We strongly favor growth companies with strong management, commitment to research and whose products and/or services enjoy dominant market positions, financial strength and profitability, and proven marketing organizations.

A Consistent and Proven Investment Process

Our firm employs a fundamental, benchmark-agnostic, and research-driven approach to asset management.

We consider ourselves owners of businesses and make decisions with a long-term investment horizon.

Focusing on innovative small and medium-sized growth companies enables us to hold our positions for an extended period of time. This has resulted in higher returns, lower turnover, and greater tax efficiency for taxable investors.

The strategy emphasizes revenue instead of market capitalization to evaluate size.

All members of the investment team are generalists, as we believe this produces the best framework for informed opinions and productive dialogue.



The calm and profitable period of the last two years ended with stock market turbulence in late 2018 not justified by the fundamentals. The S&P 500 had its worst December since 1931 losing 9%, putting the fourth quarter down 14%. The Russell 2000 declined 12% for its worst December in history. Additionally, the September–December peak-to-trough decline of 20% was the largest correction since the 2008 financial crisis.

Historically, December is the second-best month of the year with the highest probability of a positive return, so the late holiday swoon was clearly disappointing and unexpected. Investors worried about China’s economic slowdown, moderating earnings growth, the pace of Fed tightening, U.S.-China trade negotiations, political dysfunction in Washington and the Turkey/ Saudi Arabia Khashoggi conflict.

Severe corrections occur periodically as investors focus on the negatives rather than the positives. Typically, these are excellent buying opportunities as they cleanse the market of excesses and increase the potential for capital appreciation. For example, in the summer of 2011, the S&P 500 corrected 19% and subsequently rallied 37% in the next 12 months. It is difficult to predict changes in sentiment and there are reasons for caution, but we do not advise “timing the market” in response to increased volatility. In general, the long-term outlook favors equities due to a combination of sustainable earnings growth, low interest rates and moderate inflation. Today, the investment outlook is better than popular opinion suggests. The stock market gained approximately 300% in the last 10 years – one of the most impressive advances in history – yet this is often called the “most hated bull market.” Because of this skepticism, we do not suffer from excessive exuberance as many investors were underinvested during this period. The odds favor further advances ahead. A summary of last year’s index returns through December 31,2018 is as follows:

Dow Jones Industrials -3.5%
Russell 2500 -10.0%
MSCI EAFE -13.8%
S&P 500 -4.4%
NASDAQ Composite -2.8%
Wilshire 5000 -5.3%
