Last up on our list of "toxic" names is mid-cap cosmetics company Nu Skin Enterprises ( NUS). This stock has been making the exact opposite setup that MHO just exited from -- it's spent the majority of the last year in a downtrending channel. Now shares are falling back off of resistance, the spot where a glut of selling pressure has been collecting. That has been implications for investors right now, given that this stock has moved down to test support after each of the last four tests of resistance. With support considerably below NUS' current share price, that exposes shareholders to some big risks. I'd recommend getting out of shares before they fall further.
