Stephen Jen, Director of Macroeconomics and Currencies for BlueGold Capital Management's $2 billion hedge fund, is leaving to start his own company.

Jen has left the commodity hedge fund giant to establish his own business, SLJ Macro Partners. SLJ will be based in London and is expected to officially launch its first fund in the next few months.

SLJ's hedge fund will specialize in currency trading, but may also invest in commodities, equities and fixed-income to curb volatility.

Jen and SLJ will continue to have a business relationship with BlueGold, although at this time it is unclear what that relationship will entail.

Before joining BlueGold two years ago, Jen had previously worked for Morgan Stanley for more than ten years as a lead currency analyst after also working for the International Monetary Fund.
