“Global thematic impact didn’t exist, so we decided to build it ourselves," says Erika Karp in the latest ROI. Cornerstone’s Access Impact Fund is a Nasdaq-listed mutual fund that for a minimum $1,000 investment offers access to sub-advisors looking for thematic investments in small-, medium- and large-cap companies across geographies.

Karp, formerly the head of global sector research at UBS Investment Bank, is taking a stand on hotly debated investment topics that go beyond impact investing. She says active management, which has fallen out of favor because of high fees and uneven performance, is key to intentional impact.
