If you're bullish on NSH, then look for long-biased trades as long as this stock is trending above some key near-term support at $21.80 or at $21 and then once it breaks out above some near-term overhead resistance levels at $22.70 to its 50-day at $23.22 a share with high volume. Look for a sustained move or close above those levels with volume that hits near or above its three-month average volume of 205,620 shares. If that breakout hits, then NSH will set up to re-test or possibly take out its next major overhead resistance levels at $26 to its 200-day at $27.20 a share.
