My guest this week is Katherine Collins, who is the head of sustainable investing at Putnam Investments, a portfolio manager on two of Putnam’s sustainable investing funds, and the author of the book The Nature of Investing: Resilient Investment Strategies through Biomimicry. Our conversation is on the ins and outs of ESG and impact investing, a young but increasingly common topic in the investing world. This is challenging ground for me as a quant, because the data available is so new and limited—so Katherine’s perspective was very helpful as we continue to learn. Given the importance of this topic, I’m also searching for more guests with both positive and negative views on the role of ESG in an investing framework, and welcome suggestions for future guests. Please enjoy my conversation with Katherine Collins. For more episodes go to InvestorFieldGuide.com/podcast.
