Harris | Oakmark

A consistent, high-conviction approach to value investing.

An unwavering focus on value investing drives every decision at Harris Associates, investment adviser to the Oakmark Funds, and an affiliate of Natixis Investment Managers, S.A. Following a consistent, high-conviction approach since it was founded in 1976, Harris has earned a reputation as a leader in value investing. 

Harris actively manages US, international and global equity strategies, as well as US fixed income strategies for investors worldwide. As patient investors who believe that the intrinsic value of an underlying business will be recognized by the market over time, they are dedicated to delivering long-term investment performance for all clients. 

We invest in businesses that are priced at substantial discounts to our estimate of intrinsic value, believing this approach provides us with a margin of safety, which reduces risk and allows for above-average returns over time”.

Every portfolio manager at Harris follows the same investment process under all market conditions, believing that strict adherence to the firm’s three value tenets can reduce risk and increase returns over time.


Buy businesses at a significant discount to their estimate of intrinsic value


Invest in companies expected to grow per share value over time


Invest with management teams that think and act as owners

Research-driven investment process

Portfolios are built from the bottom up, focusing on company fundamentals to estimate intrinsic value and set buy and sell targets. Integral to Harris’ research-driven investment process, all research analysts are generalists. This approach ensures that they remain industry agnostic and focused on finding value, regardless of which industries or geographies are in favor at the moment.  Overall, the investment opportunities that make it through this rigorous process are then used to build portfolios, one investment at a time.
