About
Since its founding in 1984, Parnassus Investments has invested differently. The firm believes identifying good companies that are financially strong and take care of the human and natural resources that support the business is a better way to invest to create enduring value. The investment team pursues outperformance by owning concentrated portfolios of high-quality companies that have increasingly relevant products or services, durable competitive advantages, strong management teams, and sustainable business practices that are likely to thrive in a healthy economy and be resilient in a downturn.
