By Asjylyn Loder and Chanyaporn Chanjaroen Dec. 3 (Bloomberg) — K. Geert Rouwenhorst and Gary Gorton , the Yale University professors whose research earlier this decade helped spur a commodities rush, joined UBS AG’s former head of commodities trading to start a new firm. SummerHaven Investment Management LLC may offer managed futures accounts, exchange-traded and mutual funds, as well as private funds. Rouwenhorst is a partner and Gorton a senior adviser to the Stamford, Connecticut-based firm. Ashraf Rizvi , 47, who spent 14 years at UBS, will lead the firm’s trading. Gorton, 58, and Rouwenhorst, 49, “are the gurus in the commodity space, there’s no question about that,” said Matt Hougan , editor of IndexUniverse.com . “They were essentially the first ones who really made the case for having a strategic long- term exposure to commodities in your portfolio.” Commodities will likely attract a record $60 billion this year as investors seek to diversify their assets, Barclays Capital said in a November report. Total commodity assets under management will probably expand to $230 billion to $240 billion by the end of the year, the bank said. SummerHaven, founded in April, will focus on futures linked to physical commodities in metals, energy, grains, livestock and as well as coffee, cocoa, cotton, sugar and orange juice. The firm won’t trade futures tied to equities, currencies or interest rates, said Kurt J. Nelson , 40, who is a SummerHaven partner and a former UBS colleague of Rizvi. ‘Commodity Exposure’ “We’re there to provide commodity exposure across a variety of products and for a variety of clients,” including retail, endowments and pension funds, said Nelson, who worked at UBS from 1996 to 1998, then again from 2007 to July. In between, he worked for American International Group Inc . Nelson, who assisted in UBS’s purchase of AIG’s commodity index business before he left UBS in July, declined to disclose SummerHaven’s assets under management. AIG is the insurer bailed out by the U.S. Gorton and Rouwenhorst’s 2004 paper “Facts and Fantasies About Commodity Futures,” funded in part by AIG, argued that an investment in a broad commodity index would have brought positive returns from 1959 to 2004. Both are professors of finance at the Yale School of Management. Fully-collateralized commodity futures have historically offered the same return for the same level of risk as equities, they wrote. Over a long period of time, commodities rose with inflation, and had a relatively low correlation to stocks and bonds, potentially rising when other assets fell, they said. ‘Influential’ Scholarship “I would guarantee that every major endowment and pension fund that has a strategic allocation to commodities, and that’s most of them these days, have a copy of their paper on their desk,” Hougan said. “It has been critical to the asset class.” Their scholarship was “influential” in decision-making by pension funds on commodity investments, said Chris Armitage , head of U.K. investment at FourWinds Capital Management , which manages about $1.4 billion in natural-resources funds. The research “filled a void” for those interested in commodity investing that lacked the data to analyze, Rouwenhorst said in a telephone interview. “It dawned on Gary and me some time in 2003 that there seemed to be interest in commodity investing, but nobody had studied the long-term returns of the asset class.” Whether their hypothetical models will translate into real- life profits remains to be seen, said Michael Frankfurter , trading manager of Cervino Capital Management LLC in Santa Barbara, California, a commodity trading adviser and investment adviser with $10 million under management. Commodity Products “They are not traders,” said Frankfurter. “There’s a completely different culture between traders and academics. Their formula is a fictional construct. You cannot do that in real life.” While this is Rouwenhorst’s first time starting his own firm, he has worked for the last five years with large commodities firms “helping them to implement ideas from research into successful commodity products,” he said. Rizvi will lead the firm’s trading, and partner Adam Dunsby , 41, co-founder and principal of Cornerstone Quantitative Investment Group from 1995 to 2008, will do the quantitative modeling, Nelson said. In addition to Gorton, senior advisers include Steven H. Bloom , founder of Sagamore Hill Capital Management LP , and Fumio Hayashi, a former economics professor at the University of Tokyo and research associate at the National Bureau of Economic Research. Hayashi co-authored a paper with Gorton and Rouwenhorst in 2006 titled “The Fundamentals of Commodity Futures Returns.” To contact the reporters on this story: Asjylyn Loder in New York aloder@bloomberg.net ; Chanyaporn Chanjaroen in London at cchanjaroen@bloomberg.net
