Why Goldman Sachs Stock Is Rallying

Goldman Sachs stock is rallying today (Wednesday) on news that President-elect Donald Trump has tapped former Goldman partner Steven Mnuchin as Treasury Secretary.

Shares of Goldman Sachs Group Inc. (NYSE: GS) were up more than 3% in morning trading to a 52-week high of $219.07.

Goldman has spawned several Treasury secretaries over the years, including Henry Paulson and Robert Rubin. Here are some key details about 77th Treasury Secretary of the United States.

Who Is Steven Mnuchin?

Mnuchin worked at Goldman for 17 years. Following his father's footsteps, Mnuchin joined the firm at 22 and left just shy of his 40th birthday in 2002.

From there, Mnuchin joined the hedge fund of his former college roommate Eddie Lampert. Mnuchin remains a director of Sears Holdings Corp. (Nasdaq: SHLD), where Lampert reins as chairman and CEO.

Mnuchin's stint with Lampert lasted less than a year. He left to work as a portfolio manager for billionaire financier George Soros. After a year with Soros, Mnuchin left in September 2004 to start his own hedge fund, Dune Capital Management.
