Beyond big trading gains, Goldman saw banking revenues fall

Goldman Sachs (GS) announced it posted its biggest quarterly profit ever in the second quarter, thanks to headline-grabbing trading revenue. But what else did the financial powerhouse disclose?

As The New York Times' Cyrus Sanati points out, Goldman offers very few clues about how its record profit came to be. For outsiders, its fixed income, currencies and commodities trading desk might as well be a black box. But even so, there's plenty of revealing information in the results announced today.
