NEW YORK (TheStreet) -- Federal Reserve Chairman Ben Bernanke made a point to remain balanced during his testimony before Congress yesterday, as investors perceived this balance as flexibility.Bernanke introduced nothing new to markets, however, as investors across asset markets that have been tied to the Fed's easy-money policy reacted differently to the news. The first chart below is of iShares Barclays 1-3 Year Treasury Bond ( SHY) over iShares Barclays 20+ Year Treasury Bond ( TLT). This pair represents the steepness of the Treasury yield curve. As the price moves higher, the curve steepens. The pair has corrected back to its trend line over the past few weeks, and was tested Wednesday during the congressional testimony. The trend line indicates the market's belief that bond purchases will begin to slow at September's Federal Reserve meeting. The pair's failure to break below the trend signals that for all the volatility seen on Wednesday, nothing much has changed regarding expectations of Fed tapering.
