Tangoe ( TNGO) is a global provider of on-demand communications lifecycle management, software and related services to a range of enterprises, including large and medium-sized businesses, and other organizations. This stock is trading up 4.5% at $14.02 in recent trading. Today's Volume: 97,000 Average Volume: 111,214 Volume % Change: 106% From a technical standpoint, this stock has started to challenge a big breakout now that shares are clearing some past overhead resistance at $13.93 on decent volume. Market players should now watch for a sustained move and close above $13.93 on high-volume. Watch for volume at today's close that is tracking near or above 111,214, with the stock above $13.93. If we get that action, then I expect this stock to re-test $14.50 to $15.70 this week or earlier next week.
