Geoff Swerdlin
+ BIO
Geoff Swerdlin is the Chief Investment Officer of Casimir Holdings which he started building with Jim Goetz in 2020. As CIO, Geoff oversees Casimir’s investment activities in listed and unlisted asset classes including public equity, private equity, limited partnerships and real estate. He has also been instrumental in building out Casimir’s financial and operational infrastructure alongside Chief Financial Officer Vadim Reingevurts.
Geoff has been investing in public markets for over 20 years. Prior to joining with Jim to build Casimir, Geoff founded and built Partes Capital, first as an equity long/short hedge fund and subsequently as an investment advisory consultancy. He was also an analyst and portfolio manager at Kingdon Capital, a multi-billion dollar equity long/short hedge fund founded by Mark Kingdon, and has held other investment management roles at Longview Asset Management, Arience Capital and Janus Capital.
Geoff was trained as a generalist, initially focusing on the financial, consumer, industrial, and information services sectors. A close look at the subprime mortgage ecosystem fascinated him and led him to specialize in financial services at Kingdon in 2007. While maintaining coverage of global banks and asset managers, Geoff spearheaded the team’s expansion into adjacencies including payment technology, exchanges/market structure, information services and real estate/building materials. In 2011, he was promoted to portfolio manager of non-bank financials, a category representing the coverage universe he cultivated.
Geoff’s private market investing experience was episodic until Manikay Partners retained Partes Capital to advise on its proposed demutualization of The Tel Aviv Stock Exchange (TASE). In 2018, Israeli Securities Law was amended with the goal of making TASE more competitive, efficient and profitable by changing its ownership structure, and Manikay, a New York/London based investment firm run by experienced market structure investor Shane Finemore, was brought in to execute the transaction. Partes helped Manikay analyze, benchmark and value TASE; recruit and secure regulatory approval for Manikay’s co-investors; and support the demutualization and IPO process. TASE’s corporate transformation has been an unqualified success and Manikay Partners still remains deeply involved. Subsequent to the TASE investment, Partes also advised Manikay on its investment in Members Exchange (MEMX), a market operator founded by leading institutional/retail brokers, asset managers and market makers to provide competition and innovation in the cash equities market.
Geoff was raised in Baltimore and graduated from the University of Pennsylvania with a B.A. in Political Science from The College of Arts and Sciences and a B.S. in Economics from The Wharton School. Prior to embarking on his buyside career, he spent a summer at Goldman Sachs in the mergers and acquisitions group within the investment banking division.
