Most of Wall Street, and America, is still waiting for an economic recovery. Then there is Goldman Sachs.

Up and down Wall Street, analysts and traders are buzzing that Goldman, which only recently paid back its government bailout money, will report blowout profits from trading on Tuesday.

Analysts predict the bank earned a profit of more than $2 billion in the March-June period, because of its trading prowess across world markets. If they are right, the bank’s rivals will once again be left to wonder exactly how Goldman, long the envy of Wall Street, could have rebounded so drastically only months after the nation’s financial industry was shaken to its foundations.

The obsessive speculation has already begun, along with banter about how Goldman’s rapid return to minting money will be perceived by lawmakers and taxpayers who aided Goldman with a multibillion-dollar cushion last fall.
