Using Portfolio Models to Test the Robustness of Your Investments

Today’s conversation is with Jennifer Wallace, a wonderful expositor to the main ideas of value investing, but also a very deep thinker when it comes to the interaction of value investing and the market at large. Jenny is the co-founder of Summit Street Capital Management, where she is the portfolio manager of the US equity value fund. She's also a Columbian through and through as she holds a BA from Columbia College and an MBA from Columbia Business School. Jenny is a member of the advisory board of the Heilbrunn Center for Graham & Dodd Investing and a great mentor to me.

While working towards her MBA, Jenny joined the first cohort of students to take the value investing class offered by Bruce Greenwald. After being introduced to value investing, it became clear to Jenny that to be successful she needed to develop a skill set that would allow her to assess businesses, independent of conventional wisdom. To gain that perspective, she first went to work for McKinsey & Company. After leaving McKinsey, Jenny worked alongside investing legend Bob Bruce, before ultimately co-founding her firm.

On this episode, Jenny and I discuss her studies at Columbia Business School as a student in the first cohort of the value investing class, her early career with value investing legends, how Summit Street was started, how Jenny developed her investment philosophy, her approach to data analysis, the impact of the growth of the passive investing industry on active managers, and so much more!
