Traders should now look for long-biased trades in NAT once it manages to break out above some near-term overhead resistance level $8.96 to $9.60 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 volume of 580,138 shares. If that breakout triggers soon, then NAT will set up to re-test or possibly take out its next major overhead resistance levels at $10.50 to $11.50 a share. One could look to buy NAT off any weakness to anticipate that breakout and then simply use a stop that sits just below some near-term support at $8.20 a share. Traders can also just buy off strength once NAT takes out $8.96 a share with volume and then simply use the same stop below $8.20 a share. I would look to add to either position once NAT clears its 50-day at $9.60 with volume. Keep in mind that the current short interest as a percentage of the float for NAT is rather high at 10.6%. This is a decent amount of shorts involved in NAT, so we could easily see a large short-squeeze develop if the stock triggers that breakout soon.
