We recently published a list of Billionaire Andreas Halvorsen’s 10 Stock Picks With Huge Upside Potential. In this article, we are going to take a look at where BioMarin Pharmaceutical Inc. (NASDAQ:BMRN) stands against other billionaire Andreas Halvorsen’s stock picks with huge upside potential.
Ole Andreas Halvorsen is one of the prominent names among former employees of Julian Robertson’s Tiger Management. Robertson put together a formidable team of young traders – called the Tiger Cubs – in the 1990s, and most founded their own hedge funds after exit. Some other noteworthy names include Robert Citrone, Chase Coleman, and John Griffin. Halvorsen is the wealthiest Tiger Cub. Forbes Magazine ranks him at position 382 in the Richest People in the World in 2025 list with an $8 billion net worth.
The Norwegian billionaire founded Viking Global Investors LP in 1999 with former Tiger Management employees Brian Olson and David Ott. Halvorsen was an equity trader at Tiger Management, and the strategies and principles he used there form a core foundation of Viking Global’s approach. The fund conducts extensive due diligence on individual companies to identify undervalued (long) or overvalued (short) stocks. In short, Halvorsen generates much of his returns using the classic long/short equity strategy.
But most importantly, Halvorsen is popular for his bold bets. And on many occasions, these bets have returned massive gains. For instance, in the first full year of Viking Global’s existence, the fund returned 89% after fees. More recently, in Q4 2024, the billionaire made three banks his top holdings. As of April 2025, the banking sector (within Halvorsen’s portfolio) is performing well and is the only sector that is up year-to-date.
If anything, Halvorsen’s approach teaches that playing the long game might be a great strategy for favorable gains. Many of the stocks in Viking Global’s portfolio have been there for many years, often bought when they weren’t so popular. In that light, it is prudent to examine what stocks the billionaire is invested in, especially those with considerable upside potential.
We reviewed Viking Global’s Q4 2024 SEC 13F filings to compile this list. Out of the 86 holdings, we focused only on shares in companies and excluded interests in ETFs and options.
