The Mercer Family Foundation is a private grant-making foundation in the United States.
 As of 2013, it had $37 million in assets.
 The foundation is run by Rebekah Mercer, the daughter of computer scientist and hedge fund manager Robert Mercer.
Ole Andreas Halvorsen (born 1961) is a Norwegian-born investor, hedge fund manager, and philanthropist.
 He is the CEO and a co-founder of the Connecticut-based hedge fund, Viking Global Investors.
 Viking had $16.7 billion under management as of April 2012.
 Halvorsen has consistently ranked among the top earning hedge fund managers, placing 11th in Forbes' 2012 rankings and 9th in 2015, according to Institutional Investor's Alpha.
Arvind Raghunathan (born October 24, 1963) is a Hedge Fund Manager.
 He is the founder and CEO of Roc Capital Management LP (the largest Hedge Fund launch of 2009).
 On February 25, 2009, it was announced that Raghunathan and his associates would be leaving Deutsche Bank to set up the independent quant trading hedge fund.
 It was rumored in late July 2013 that the main fund of Roc Capital Management would be liquidated after losses.
Here are the ten largest hedge funds in the world ranked by assets under management as of mid 2016.
 Only assets in private funds following hedge fund strategies are counted.
 Some of these managers also manage public funds and offer non-hedge fund strategies.
 For example, BlackRock is the largest investment manager in the world with $5.7 trillion assets under management in all types of funds and AQR Capital Management is the largest provider of public mutual funds following hedge fund strategies with $23 billion in public hedge fund assets under management in addition to the $63 billion of private assets listed below, and an additional $90 billion in traditional investment funds.
Steven Edward Drobny (born April 29, 1972) is an American hedge fund advisor and published author.
 He is the founder of Drobny Capital, a consulting and investment advisory business focused on fundamental discretionary global macro and commodity hedge fund strategies.
 Drobny is the author of "The Invisible Hands: Top Hedge Funds on Bubbles, Crashes and Rethinking Real Money (John Wiley & Sons, 2010)" and "Inside the House of Money: Top Hedge Fund Traders on Profiting in the Global Markets (John Wiley & Sons, 2006)"
Paul Tudor Jones II (born September 28, 1954) is an American investor, hedge fund manager, and philanthropist.
 In 1980, he founded his hedge fund, Tudor Investment Corporation, an asset management firm headquartered in Greenwich, Connecticut.
 Soon after, he created the Tudor Group, a hedge fund holding company that specializes in fixed income, currencies, equities, and commodities.
Hedge fund replication is the collective name given to a number of different methods that attempt to replicate hedge fund returns.
 The hedge fund industry has boomed over recent years and various studies by investment banks as well as academic papers have shown that hedge funds may be nearing an alpha generating capacity constraint.
 This means hedge funds can no longer produce alpha in aggregate.
 Replication has been claimed to remove the illiquidity, transparency and fraud risk associated with direct investment in hedge funds.
 With the belief that the pursuit of alpha is a zero-sum game, more investors are looking to simply add "Hedge Fund Beta" to their portfolio.
 These early investors have been rewarded as the replicators outperformed their direct investment cousins in 2008 due to their greater liquidity and lower use of leverage.
Alfred Winslow Jones (9 September 1900 – 2 June 1989) was an Australian investor, hedge fund manager, and sociologist.
 He is credited with forming the first modern hedge fund and is widely regarded as the "father of the hedge fund industry."
Robert Leroy Mercer (born July 11, 1946), better known as Bob Mercer, is an American computer scientist, a developer in early artificial intelligence, and co-CEO of Renaissance Technologies, a successful hedge fund.
Lee S. Ainslie III is the head of hedge fund Maverick Capital.
 Ainslee helped form the hedge fund in 1993 at the invitation of billionaire Sam Wyly.
 He and other former employees of Julian Robertson's Tiger Management Corp. have been nicknamed "tiger cubs" in the hedge fund industry.
 Ainslie is a value investor that is particularly known for his investments in the technology sector.
 Maverick Capital Management LP was reported to have $9 billion under management at year-end 2013.
