The SPDR Financial ETF ( XLF ) broke out to new highs Wednesday, while SPDR S&P Regional Bank ( KRE ) surged 2.1%. Yields on the two-, five-, 10-, and 30-year Treasuries began rising following Fed Chair Janet Yellen's speech Tuesday, Tradeweb noted. Yellen fanned expectations of a December interest-rate increase, saying that raising interest rates gradually is the appropriate strategy considering the uncertainty on inflation, Bloomberg reported.
