Today I used Barchart to sort the S&P 400 Mid Cap Index stocks to find the 5 best Mid Caps for Momentum Investors. First I sorted by the most frequent number of new highs in the last month, then again for technical buy signals of over 80%. Next I used the Flipchart feature to review the charts for consistency. Today's watch list additions include:

UGI Corp (NYSE: UGI), IDEXX Laboratories (Nasdaq: IDXX), CDK Global (Nasdaq: CDK), Gartner (NYSE: IT), and Arthur L Gallagher (NYSE: AJG)
