Harris Associates focuses on value investing and builds client portfolios by identifying companies trading below their intrinsic value and viewing each stock as ownership in a business. The process analyzes long-term quality, cash flow, and capital allocation to select holdings expected to grow value over time, then maintains positions through market ups and downs. It differentiates itself with a disciplined, long-term approach, emphasis on treating stocks as business ownership, and a collaborative culture that prioritizes client outcomes over short-term performance. The goal is to deliver attractive, long-term returns for clients by investing in quality businesses at prices below their intrinsic value using a steady, well-defined process.
