In economics and finance, arbitrage is the practice of taking advantage of a difference in prices in two or more markets – striking a combination of matching deals to capitalize on the difference, the profit being the difference between the market prices at which the unit is traded. When used by academics, an arbitrage is a transaction that involves no negative cash flow at any probabilistic or temporal state and a positive cash flow in at least one state; in simple terms, it is the possibility of a risk-free profit after transaction costs. For example, an arbitrage opportunity is present when there is the possibility to instantaneously buy something for a low price and sell it for a higher price.

Howard Hubler III, known as Howie Hubler, is an American former Morgan Stanley bond trader who is best known for his role in the fifth largest trading loss in history. He made a successful short trade in risky subprime mortgages in the U.S., but to fund his trade he sold insurance on AAA-rated mortgage-backed collateralized debt obligations that market analysts considered less risky, but also turned out to be worthless, resulting in a massive net loss on his trades. His actions while handling credit default swaps (CDS) directly resulted in the loss of roughly US$9 billion during the 2007–08 financial crisis—the largest single trading loss in Wall Street history when adjusted for inflation, and the largest at the time. The only bigger single losses in nominal terms came in 2012 with Bruno Iksil and in 2021 when Bill Hwang lost around $10 billion on total return swaps.
