As Bank of America (BAC -5%) and Citigroup (C -3.2%) swoon following earnings, regionals reporting today fly higher: PNC +3.7%, FITB +4%, BBT +2.2%. Were their results that much better? Maybe. More likely it's a rotation out of the high-flying TBTFs into the more modestly valued regionals. The regional bank ETF (KRE) gains 1.3% vs. the XLF flat.
