E221: From Citadel to Family Office CIO: Sid Malhotra’s Investment Lessons

What really happens inside the hidden world of family offices—and why do they invest so differently from institutions? In this episode, I explore that question with Sid Malhotra, Chief Investment Officer at Kactus Capital, a single family office. Sid reveals how family offices align incentives between principals and investment teams, the advantages of having true “skin in the game,” and why their long-term, absolute-return mindset stands apart from pensions, endowments, and foundations. We also discuss the unique strategic role family offices play—from backing zero-to-one opportunities to leveraging deep sector expertise and networks—and how Sid’s career path, from Citadel to Pritzker Group to his current role, shaped his approach to risk, alignment, and building resilient portfolios.

Highlights:

• Alignment over agency: how Kactus ties compensation and co-investment directly to long-term portfolio performance.
• Single vs. multi-family offices: why governance, focus, and principal control make a difference
• Strategic capital: family offices as early backers of crypto, seed managers, and illiquid opportunities institutions avoid
• Lessons from six years at the Pritzker Group: how legacy ownership and manufacturing DNA shape an investment lens
• Absolute returns and relative returns: why compounding capital while minimizing losses guides Sid’s philosophy
• Preparing for corrections: dry powder, T-bills, and opportunistic offense in market sell-offs
• Citadel training: lessons on multi-strategy flexibility, thinking across the capital structure, and risk-reward sizing
• The total portfolio approach: blending macro-awareness, bottoms-up selection, and thematic top-down views
• Career advice from Booth to CIO: why networking early is as critical as working hard
