The company was founded in 2000 by Nicholas M. Maounis and based in Greenwich, Connecticut. Throughout much of its history, convertible arbitrage was the firm's primary profit vehicle. Maounis had prior to founding Amaranth Advisors worked at Paloma Partners as a portfolio manager covering debt securities.
During 2004-2005, the firm shifted its emphasis to energy trading by Canadian trader Brian Hunter who invested in the natural gas market. In 2005 the firm made an estimated $1 billion on rising energy prices after Hurricane Katrina curtailed production.
Amaranth Advisors' troubles began in December 2005 as natural gas prices began to decline and Amaranth Advisors portfolio was structured for the price to move in the spring months of March or April. Hunter who was 32 years old at the time invested heavily in natural gas futures which resulted in a single week loss of $6.5 billion when prices failed to move as expected.
Sept 18th 2006 – client told of loses
On Monday September 18, 2006 Amaranth Advisors told investors that natural gas market downturn had resulted in $3 billion of loses. Further Amaranth Advisors told investors that it was working with lenders for maintaining liquidity while also and now selling portfolio holdings "to protect our investors." Traders sold securities that could be liquidated without undermining and disrupting the energy market; these included convertible bonds and high-yield corporate debt.
Transferring energy portfolio
The fund had up to $9 billion under management and reports indicated their losses may have exceeded 65 percent of their investment. Amaranth transferred its energy portfolio to a third party consisting ofCitadel LLC and JPMorgan Chase.
On September 29, 2006, Amaranth's founder sent a letter to fund investors notifying them of the fund's suspension and on October 1, 2006, Amaranth hired the Fortress Investment Group to liquidate its assets. In September 2006 Amaranth Advisors investors were informed that they could not pull their money out and that redemptions would be temporarily suspended for two months. Ten years later 90% of assets had been returned and 10% of investor assets were still frozen through December 2016.
On July 25, 2007, the Commodity Futures Trading Commission charged Amaranth and Hunter with attempting to manipulate the price of natural gas futures. Additionally, the Federal Energy Regulatory Commission charged Amaranth, Hunter and trader Matthew Donohoe with market manipulation. The CFTC and the FERC had conflicting versions of what Hunter did, and are currently competing over jurisdiction. In 2014 Hunter settled with the CFTC, paying a $750,000 fine and accepting a ban from trading all CFTC-regulated natural-gas products.
2010 Federal Energy Regulatory Commission
On January 22, 2010, a Federal Energy Regulatory Commission administrative law judge ruled that Hunter violated the Commission's Anti-Manipulation Rule. Judge Carmen Cintron found that "Hunter intentionally manipulated the settlement price of the at-issue natural gas futures contracts. His trading was specifically designed to lower the NYMEX price in order to benefit his swap positions on other exchanges." The decision is subject to review by the Commission.
Legal
In November 2007 Amaranth Advisors filed a lawsuit against JPMorgan claiming $1 billion in damages on the grounds that the bank interfered in the company's efforts to avoid collapse after natural-gas trades losses in 2006. The suit claimed that JP Morgan as Amaranth Advisors's clearing broker use their position to prevent Amaranth Advisors from derisking their exposure from its natural-gas derivatives portfolio by preventing the portfolio from being sold to first Goldman Sachs and later Citadel LLC. In December 2012, the New York State Court of Appeals upheld an earlier dismissal of the case. During the collapse of Amaranth Advisors, Centaurus was credited as being one of the major players on the other side of their position.
Criticism
During the week of September 11, 2006 one week before clients were notified of loses Amaranth Advisors was seeking new investors and marketing their fund as being up 25 percent for the year. The New York Times reported that Amaranth Advisors said it was a multi-strategy fund though acted "like an energy and commodities fund. When it bet big on natural gas and lost, it was apparent that it was neither multistrategy nor particularly well hedged" and also that in Amaranth Advisors' case "multistrategy" seems to have been a misnomer at the fund.
