No area of the stock market benefited more than financials following the Federal Reserve's most recent comments. Now traders are betting the group's climb to the highest level in a decade has a ways to go. An index of financial stocks climbed as much as 1% on Wednesday, with the majority of those gains coming immediately after the Federal Open Market Committee (FOMC) announced that it will slowly begin the long-awaited unwinding of its balance sheet next month. The gauge finished the day up 0.6%, at its loftiest point since 2007, amid optimism that an eventual rate hike will boost interest income for firms. Looking ahead, bullish sentiment is continuing to swell in financials.
