Oak’s Approach

Throughout our history, Oak has remained committed to the same investment philosophy and process. We employ a dual-concentrated approach, focusing on both sector and stock level opportunities, and invest with a long-term view.

Top-Down

We identify favorable sectors poised for growth.

Bottom-Up

Within those sectors, we pinpoint high-conviction stocks
supported by strong, multi-cycle growth drivers.

In an increasingly short-term oriented investment environment, we believe investing for the long term better allows our clients to build wealth. Oak is dedicated to discovering and investing in companies with the potential to grow throughout market cycles and over time.

Oak Timeline

 

Oak Associates was founded in 1985 by Jim Oelschlager after 15 years as Director of Pension Investments and Assistant Treasurer at Firestone Tire & Rubber Company. Under Jim’s leadership, Firestone’s pension fund grew from $250 million—initially underfunded by another $250 million—to $1.2 billion, with a $330 million surplus by 1984. Firestone then chose to terminate the plan, allowing Jim to establish Oak Associates, with Firestone as its first client.

Since its founding, Oak Associates has remained committed to its core investment principles: long-term focus, low turnover, concentrated holdings, and fully invested portfolio management.
