The S&P 500 and the Dow scaled new highs on Thursday as JPMorgan's strong results set an upbeat mood for earnings and spurred a rally in financial stocks. While the Bank of England unexpectedly left interest rates unchanged, investors saw hope after the central bank signaled there would be a stimulus program in August, once the impact of Britain's vote to leave the European Union had been assessed. JPMorgan, the biggest U.S. bank by assets, reported quarterly revenue rise that beat estimates by a hefty margin. The bank's shares rose 2.6 percent, while the S&P financial index's 1.1 percent gain led the gainers among the 10 major S&P sectors. "We saw a significant beat from JPMorgan and that's helping the psychology of the market," said Art Hogan, chief market strategist at Wunderlich Securities in New York. "With the weaker dollar helping commodities and better-than-expected economic data, the market is taking the path of least resistance with an upward bias." At 10:52 a.m. ET (1452 GMT) the Dow Jones industrial average was up 132.37 points, or 0.72 percent, at 18,504.49. The S&P 500 was up 12.22 points, or 0.57 percent, at 2,164.65. The Nasdaq Composite was up 31.58 points, or 0.63 percent, at 5,037.31. Wall Street's record-breaking rally extended to the fourth day this week and Hogan said the market needs to see earnings growth to sustain the rally.

Stocks still look expensive with the S&P 500 trading near 17.3 times forward 12-month earnings, above the 10-year median of 14.7 times, according to StarMine data. Japanese messaging app operator Line Corp soared as much as 36 percent in their debut, benefiting from the market rally. Strong economic data released earlier on Thursday also helped the markets hum along with weekly jobless claims holding at lower levels and producer prices recording their biggest gain in a year in June. Traders say if economic data continues to point to momentum in the economy, the Federal Reserve could raise rates later in the year.
