Goldman Sachs and JPMorgan Chase Co. have emerged two bellwethers of the US finance sector in the post-bailout Wall Street, leading the surge of optimism with their strong profits in the Y 2009 Q-2. Six major US banks have reported their second-quarter profits in the past two weeks, vastly beating analyst predictions. The business of Goldman has little to do with common consumers, its quarterly earnings of more than US$3.4B posted were buoyed by record results in its trading and underwriting business. According to the quarterly report, the Wall Street giant generated a record US$6.8B in revenue from fixed income, currency and commodities trading during the quarter. Revenue from equity underwriting jumped to US$736M form UD$ 48M in the first quarter compared with US$616M last year. JP Morgan Chase, the largest US bank by market value, posted a US$2.72B earnings, and made its profits mainly from investment-banking services including bond and equity trading, and underwriting debt to help companies issue shares and bonds, not commercial loans and consumption credit.
