Below, we outline five of the world’s most famous businessmen who made fortunes playing the commodity space, paving the way for future investors.

An Alabama native, Rogers began his entrepreneurial career early, collecting soda bottles at the ripe old age of five. He attended Yale and Oxford, earning degrees in history, philosophy, politics and economics. In the 1970s, with just $600 to his name, Rogers teamed up with George Soros to create the Quantum Fund, which gained 4,200% in 10 years. By 1977, at the age of 35, Rogers earned his first $1 million in net worth. In the 1980s, Rogers retired to have, what he called in a 2009 interview with Steve Forbes, “another life.”

After travelling the world on his motorcycle during the 1990s, Rogers founded the Rogers International Commodities Index in 1998. In 2007, he invested in the American dollar. His thought process, as he revealed in a Forbes interview, was that currency was being debased. He places a heavy investment focus on agriculture, supported by his findings that students aren’t studying to be farmers anymore. To Rogers, this fact spells profit because it will lead to falling supplies with increasing demand and prices. He believes that commodities across the board are currently undervalued and is further expanding his focus, looking for hidden gems in Russia, possibly even including the ruble.

After surviving Nazi-occupied Hungary, 16-year-old George Soros left Hungary in 1947 and studied at the London School of Economics. At the time, he also worked as a porter, salesman and waiter.

Eventually making it to New York, Soros began working as a trader and analyst. He applied philosophical social theories to the market in an early version of behavioral finance, and used this to predict the materialization of financial bubbles. After helping develop an offshore fund in 1967, he joined Jim Rogers in creating the Quantum Fund in the 1970s.

Soros has long felt that a capacity for deep thinking is necessary for investing successfully. He also favors retrenching when facing losses, rather than recouping. Investing hasn’t been all rosy for Soros; in 2008, he bought shares of Bear Stearns at $54 just before the JP Morgan merger, leaving his fund at a loss for the year.

In 2012, Soros added 884,000 shares of SPDR Gold to Soros Fund Management, after having sold much of his gold and silver holdings in May for a 65% gain. Also, like Rogers, Soros is a fan of agriculture, as evidenced by his $232 million stake in South American food and energy company Adecoagro (AGRO).

If there’s one thing that can be learned from investor Eike Batista, it’s to use the intrinsic insider knowledge one has of his or her own birthplace and its resources when investing and speculating. Batista was educated in Brazil until the 12th grade, at which time he followed his father, who was creating offshore offices for Companhia Vale do Rio Doce, to Europe. In 1974, Batista studied metallurgy at a German university before dropping out.

When his parents stopped financially supporting him, Batista began selling insurance door to door and found the independent lifestyle stressful. In 2010, he told interviewer Charlie Rose that this stress to support himself was a great experience that made him tougher. At 23, he returned to Brazil to find a major gold rush occurring in the Amazon River basin. Seizing the opportunity, he started a trading company to buy and sell gold. After a year and a half Batista had earned a $6 million profit on the $16 million in gold traded through him. Since competition had then introduced itself, he decided to go in a different direction and, in 1983, bought and mechanized one of the pick-and-shovel operations. It was the first mechanized alluvial gold mine in the Amazon and ended up earning Batista $1 million per month.

In the same 2010 interview with Rose, Batista predicted the presence of roughly 100 billion barrels of recoverable oil in his new Brazilian oil field find. Sadly, just six months after pumping its first barrel, the field was not found to be as fertile as originally thought and Batista’s group, OGX, was forced to reduce its production target, resulting in $15 billion in paper losses. As Batista explained on Twitter, however, he hadn’t actualized any of the losses since the assets weren’t sold, although this shortage will likely have a ripple effect on his other plans to monetize the oil.

A passionate trader with a talent for inventing new ways to trade, Hite grew up in Brooklyn and had a sort of non-descript beginning. He wasn’t an athlete or a scholar and he tried a wide variety of jobs to find himself, including acting, screenwriting and working as a promoter for rock bands. All of these failed ventures were the hotbed of his training; he recognizes that the failures and setbacks he experienced were exactly what enabled him to later succeed.

In the 1970s, Hite became a broker and commodities trader. He founded Mint Investment Management in 1981 and created computerized statistical models for the company. Mint had annual returns of more than 30% from 1981 to 1994 and, just 10 years after opening, was the largest commodity trading advisory in the world. Hite left in 2000, and in 2001, worked on his trading models through Hite Capital Management, a family organization that had a 70% return in 2008 and had only one year of losses. That same year, Hite returned to hedge funds as president of the U.S. Division of ISAM (International Standard Asset Management) [see also The Ten Commandments of Commodity Investing].

One of Hite’s key moves is to build an assumption of loss into every deal so that he can plan accordingly. He realizes that the markets are not rational and follows trends while exploiting emotional responses.

Trader Vic, as he is known, says in his 1991 book, Methods of a Wall Street Master, that as a child he wanted to be a hero; not a super-power-endowed crusader, but a realistic hero. He notes that his dream would have been to be a Ty Cobb or gold medal Olympian. He goes on to say that eventually he learned to let this “quest for glory” go. Traders who’ve watched Sperandeo grow from a Wall Street quote boy in 1966 to an independent trader might think otherwise. Between 1971 and 1988, Hite never had a losing year in his personal account, and during the same period he grossed $10 million for all accounts managed (including his own).

Now president of Alpha Financial Technologies, Sperandeo is an expert in the energy and metals sectors. In a 2012 interview with HardAssets Investor, he stated that he watches what governments are and aren’t doing in order to form opinions about the overall economy and markets. One of his concerns about the current American administration’s activities is that they have created an overly regulated political environment. As a result, he thinks businesses are holding back, but says he would become bullish on commodities and equities if it seemed as though the current administration were going to lose its power. Sperandeo was very critical of former Fed Chairman Ben Bernanke throughout his tenure and is a proponent of the gold standard.

In 1987, Sperandeo predicted the market crash, cementing his role as a thought leader in the trading community. His belief in putting a life expectancy on the bullish and bearish moves of the market has revolutionized technical analysis.
