Aragon Global Management, the global equities hedge fund firm founded by Anne Dias, the former wife of Citadel boss Ken Griffin, has closed its Chicago office and relocated its headquarters to Miami, according to a report by Bloomberg.

Aragon, which manages about $320 million, joins a growing list of hedge fund firms that have set up shop in the tax-friendly Sunshine State, including Griffin's Citadel, which also swapped Chicago for Miami alongside the billionaire's market-making firm Citadel Securities.

According to an unnamed Bloomberg source, as well as its new HQ in Miami, Aragon is to maintain its existing office in Manhattan.
