Investment Philosophy

We are guided philosophically by a focus on academically documented inefficiencies. We look for evidence of misunderstood transformational change at the company level that will result in better-than-expected future growth and companies that are well-positioned to benefit from material secular growth drivers. These occurrences often result in exceptional investment opportunities. We seek these opportunities through geographically focused products.

Foundational Philosophical Pillars

  • philo-01Academically established and time-tested research based on behavioral biases that can lead to market mispricing.
  • philo-02Identification of securities where we believe the marketplace has incorrectly assessed recent information and signals, leading to the underestimating of future earnings growth.
  • philo-03Use of a bottom-up, disciplined, and repeatable investment process to assess each company’s fundamental business and identify discounts from fair value.
  • philo-04Being nimble and attentive in capitalizing on perceptional lags in pricing.

Primary Areas of Focus
Oberweis seeks to uncover opportunities to fulfill small-cap mandates. Each of our products is managed by a dedicated team specializing in the application of our philosophy to a specific product’s objective.

U.S. Growth Products

We believe alpha is generated by investing in companies that are:

  • Growing sales and/or earnings in excess of expectations.
  • Experiencing a fundamental change that is misunderstood.
  • Capable of generating results beyond expectations in the future.
  • Attractively valued based on our own proprietary estimates.

The foundations of our philosophy are based on the Post-Earnings Announcement Drift. This phenomenon is grounded on the behavioral biases and tendencies exhibited by investors.

The Post-Earnings Announcement Drift exists when investors systematically underreact to new information contained in surprising earnings reports.

For our U.S. growth-oriented products, we search the U.S. markets for companies that have reported a significant positive earnings surprise, signaling that something profound may be changing at the company that is not fully appreciated by the average investor. Our research team seeks to understand if that change is sustainable and is likely to drive future earnings surprises, which would suggest the company’s current valuation is compelling. Our team leverages a focused investment process and years of investing experience to efficiently identify companies where earnings power is underestimated and pricing inefficiencies exist.
