Flat trading throughout the day didn't deter major indexes from picking steam Thursday afternoon after ultra-bear economist Nouriel Roubini, said he thinks the worst is over. "The free fall of the U.S. economy has stopped," he said at a conference in New York. "The economy is still contracting, but slowly." He added that the government may need to supply a second round of stimulus funding late this year or in early 2010.

All eyes were on earnings reports, with JPMorgan Chase (JPM) reporting surprise results to the upside Thursday morning. The bank said it earned $2.72 billion, or 28 cents a share, during the second quarter, compared with $2 billion, or 53 cents a share, in the year-ago period. The bank also recorded record revenue of $28.62 billion in the second quarter. Analysts had expected JPMorgan to earn 6 cents a share on revenue of $25.9 billion. Bank of America (BAC) and Citigroup (C) report Friday.

The Dow Jones Industrial Average closed up 95 points at 8711. The Nasdaq gained 22 at 1885 and the S&P 500 picked up 8 to finish at 941.
