The S&P Mid-Cap 400 Index is approaching its recent highs in the 252 area. Though the surprise discount rate hike is pressuring stocks early Friday, the NYSE A/D line (see bar chart) is very close to making new highs and continues to act stronger than prices. The RS chart shows the move back above its WMA in early December as it has continued to perform better that the S&P 500. There is key support now for the S&P 400 at 680.
