Stocks are narrowly higher in the first few minutes of trade. The gains, though moderate, have been enough to take the S&P 500 to a fractionally improved two-year high. Support for stocks is broad as all 10 of the major sectors sport gains. Materials and energy stocks are leading the way with respective gains of 0.7% and 0.6%. Selling resumes in the Treasuries complex with the 10-yr yield touching a session high of 3.391%, its highest level since early June.
