Biography

Andreas Halvorsen was born in Norway in 1961. He received a B.S. from the Norwegian Naval Academy in 1986 and an MBA from Stanford Graduate School of Business in 1990. After graduating from Stanford, Halvorsen joined Tiger Management, the legendary hedge fund founded by Julian Robertson. He quickly rose through the ranks, becoming a senior managing director and co-chief investment officer. His experience at Tiger Management, particularly during its peak performance years, provided a foundational understanding of global macro and fundamental equity investing. In 1999, Halvorsen, along with colleagues David Ott and Brian Olson, departed Tiger Management to co-found Viking Global Investors. The firm was strategically launched with seed capital from Julian Robertson, a testament to Halvorsen's proven capabilities. Viking Global quickly established itself, applying a rigorous fundamental long/short equity approach. Initially, the firm focused on a broad range of sectors, but over time, it developed expertise in healthcare, technology, and consumer discretionary, maintaining a global investment mandate. Under Halvorsen's leadership, Viking Global grew into a multi-billion dollar firm, recognized for its strong risk-adjusted returns and adaptive investment style. The firm navigated various market cycles, including the dot-com bust, the 2008 financial crisis, and subsequent periods of volatility, demonstrating resilience and strategic flexibility. Halvorsen stepped down as CEO of Viking Global in 2017, transitioning to co-chief investment officer, and then to chairman in 2019, while remaining actively involved in the firm's investment strategy. His leadership philosophy emphasized deep fundamental research, portfolio diversification, and a disciplined approach to both long and short positions.
