Most disciplined Tiger Cub with excellent 25-year track record, strong risk management, and quality-focused approach, but long/short structure and moderate diversification limit direct relevance to our concentrated long-only strategy.

Investment Philosophy & Portfolio Style
Philosophy
Fundamental, research-driven long/short equity investing with a focus on quality businesses with sustainable competitive advantages. Halvorsen's approach: (1) Deep fundamental research -- Viking employs a large research team and is known for exceptionally thorough analysis, (2) Quality bias -- tends to invest in high-quality businesses with strong competitive positions, (3) Long/short equity -- actively shorts overvalued companies alongside long positions, (4) Moderate concentration -- top 10 at 55.9% of portfolio is less concentrated than Tiger Global or Lone Pine, (5) Sector diversification -- broader than pure tech players, with exposure to healthcare, financials, technology, and consumer sectors, (6) Disciplined risk management -- Viking has generally avoided catastrophic drawdowns while maintaining strong returns. Philosophy emphasizes understanding businesses deeply and finding mispricing through rigorous fundamental work.
Portfolio Style
Large, moderately concentrated long/short equity portfolio. 76 equity holdings with top 10 representing 55.9% of portfolio. AUM approximately $37.7B (13F), one of the largest hedge funds globally. Diversified across sectors -- technology, healthcare, financials, consumer, industrials. Uses both long and short strategies. The portfolio is more balanced than peers like Tiger Global or Coatue, with broader sector diversification. Turnover is moderate. Q4 2025 performance was +4.94%.
Background
Andreas Halvorsen (born 1961 in Norway) co-founded Viking Global Investors in 1999 after working at Tiger Management under Julian Robertson. He served in the Norwegian Navy's special forces (naval commando) before attending Williams College (BA) and the Wharton School (MBA). Viking is based in Greenwich, Connecticut and manages approximately $37.7 billion in 13F-reported assets as of Q4 2025, making it one of the largest and most successful Tiger Cub operations. Halvorsen is known for being extremely disciplined, detail-oriented, and process-driven -- qualities often attributed to his military background. Net worth estimated at $6-8 billion.
Track Record
Excellent long-term track record -- one of the best among Tiger Cubs and hedge funds broadly. Viking has delivered estimated 15-20% annualized returns since inception in 1999, with relatively controlled drawdowns compared to peers. The fund navigated 2008 reasonably well and did not suffer the catastrophic 2022 losses that hit Tiger Global. Key strengths: (1) Consistency -- Viking has been consistently profitable over its 25+ year history, (2) Risk-adjusted returns -- better Sharpe ratio than more aggressive Tiger Cubs, (3) Scale -- has maintained strong performance even as AUM grew to $37.7B, which is very difficult. The combination of strong absolute returns, good risk management, and ability to scale makes Viking's track record among the most impressive in the hedge fund industry.
Notable Holdings
As of Q4 2025 (13F), Viking's $37.7B portfolio spans 76 positions across multiple sectors. Historical major holdings have included Visa (V), UnitedHealth Group (UNH), Amazon (AMZN), Microsoft (MSFT), and various large-cap quality companies across healthcare, technology, and financial sectors. The portfolio tends toward large-cap, high-quality businesses with strong competitive positions -- more blue-chip oriented than the growth-at-any-price approach of some Tiger Cubs.
Transparency & Integrity
Transparency(Score: 5/10)
Standard hedge fund transparency through quarterly 13F filings. Viking does not publicly share investor letters or detailed performance data. Halvorsen is very private and rarely gives interviews or public speeches. The fund's large size means its 13F filings provide meaningful insight into portfolio positioning. However, short positions are not disclosed (standard for long/short funds). Overall, compliant but quite private.
Integrity(Score: 9/10)
Very strong integrity record. No fraud, insider trading, or regulatory scandals in 25+ years. Halvorsen is known for running a disciplined, professional operation. His military background is often cited as contributing to institutional discipline and ethical standards. The fund has grown steadily without controversy. Halvorsen is notably private and avoids the flashy lifestyle associated with some hedge fund managers. Clean record across all dimensions.
Relevance to Us
Moderate relevance. Positives: Halvorsen's emphasis on quality businesses with competitive advantages aligns with our interest in fundamentally great companies. His disciplined risk management and avoidance of catastrophic losses resonates with our 'little chance of losing money' philosophy. The focus on deep fundamental research is admirable. Track record is genuinely impressive. Negatives: Long/short approach diverges from our long-only philosophy. Moderate concentration (55.9% in top 10) is less concentrated than we prefer. 76 holdings is more diversified than our ideal. No particular AGI thesis or technology-forward conviction. The fund's size ($37.7B) means it's effectively a large-cap quality fund, which may not offer the asymmetric opportunities we seek.
