Banks have been hammered lately amid worries about the U.S. economy as the yield curve has flattened — with sections of the curve inverting this month — signaling diminished expectations for growth. Keefe, Bruyette & Woods' bank index is down more than 15 percent in 2018, compared with a 1.3 percent decline of the S&P 500.
