Cornerstone’s Bookshelf

We believe shared experiences and education make us better investors and partners. Every six months, the entire firm reads one book together and meets to discuss it. These books are listed below:

2H 2023: "Think Again" by Adam Grant

Adam Grant, who was a business school professor of multiple partners at Cornerstone, discusses the power of nimble thinking. In an industry where getting it right 60% of the time represents success, it is important to constantly re-assess our positions and perspectives in the face of updated evidence, and the failure to do so could lead to significantly worse outcomes. It also helped us re-focus on the power of internal constructive engagement among our teams to refine our thinking on a topic.

1H 2023: "Extreme Ownership" by Jocko Willink and Leif Babin

Given the potential consequences of their actions for themselves and others, Navy Seals focus intently on pro-active and re-active decision-making. This book explores the importance of taking ownership and responsibility over one’s actions, both before and after they occur. Using case studies from real combat situations and key frameworks, it helped us understand ways we can better manage our decision-making processes and assess the outcomes of them, both as a team and individuals.

2H 2022: "Thinking in Bets" by Annie Duke

As investors, we recognize that the market is a complex adaptive system with constantly changing information, and we can never make a decision with 100% certainty. This book, by a professional poker player and Penn psychology Ph.D., focuses on decision-making under that uncertainty. Duke’s concept of “thinking in bets” helped us focus on the inherent split between the skill-driven decisions we make (which we can control) and the luck-driven outcome of those decisions (which we can’t control).

Below is a (not even close to exhaustive) list of books about investing, business, and firm culture that Cornerstone team members have found helpful throughout our careers.
