Coming off a solid first two weeks of the year, investors head into the thick of corporate earnings season.

Some of the world's largest banks will provide a snapshot of the global economy they help finance, when they report results from the last three months of the year. Bank of America (BAC), JPMorgan Chase (JPM), Citigroup (C), Goldman Sachs (GS) and Morgan Stanley (MS) are all on tap to report. The financial sector is expected to be a standout in what has been a lackluster quarter for earnings growth.

Banks likely got a boost from Americans rushing to refinance their mortgages, locking in low interest rates.

S&P 500 companies are expected to report overall earnings growth of 2.4% for the last three months of 2012, according to FactSet Research. That's better than the 1% decline in the third quarter. Excluding the financial sector, earnings growth for S&P 500 companies is estimated to be just 0.2%.
