To figure out which stocks you should be avoiding this month, we turn to the charts for a technical look at five stocks that could turn "toxic."

Molson Coors Brewing (TAP) becomes a sell if shares violate support at $95. The other shoe dropped this week in shares of Gilead Sciences (GILD) . Downside risk remains elevated in February from here.

Chubb (CB)  looks "toppy" following its recent rally. It's a sell below $129. SK Telecom's (SKM)  long-term downtrend is still intact. Sell the rips. Orange (ORAN)  is a textbook example of a head and shoulders top, and it signals a sell below $15.10.
