Let's take a look at four "toxic stocks" to sell - and when to sell them.
Korea Electric Power Corporation's (KEP) descending triangle pattern signals a sell below $17.70.
A rounding top in Williams Partners LP (WPZ) means that shareholders should book their gains if shares violate $39.
Royal Gold Inc. (RGLD) downtrend is still intact in 2017.
Vale SA (VALE) is starting to look "toppy" thanks to a head and shoulders pattern. It's a sell if shares violate $9.50.
