DexCom Inc. /zigman2/quotes/201324608/composite DXCM -3.11% , which gapped down sharply in early November, fought its way back to its declining tops line in a rising flag all month. However, the stock has broken down in the last three sessions on a pick up in volume, falling another 2.78, or 4%, to 65.29, on 5.4 million shares traded Wednesday. That's huge downside volume for this stock. Watch for a test of the early November low around 59.00, and eventually 52.00.
