After some early selling, the markets have floated back to the positive side. This is not surprising as light volume plays a key role in an up market. In addition, the S&P 500 broke out of a triangular range yesterday. This means further upside in the next week is likely. The SPDR S&P 500 ETF (NYSEARCA:SPY) is trading at $127.58, +0.09 (+0.07%). The action today is known as consolidation.
