If you're in the bull camp on WFR, then I would look for long-biased trades once this stock manages to break out above some near-term overhead resistance levels at $2.59 to $2.69 a share, and then once it takes out its 200-day at $2.85 a share with high volume. Look for a sustained move or close above those levels with volume that registers near or above its three-month average action of 4,373,750 shares. If that breakout triggers soon, then WFR will set up to re-test or possibly take out its next major overhead resistance levels at $3.35 to $3.77 a share.
