This stock just gapped down a few weeks ago from around $11 to $6.50 a share with huge volume. Following that sharp gap lower, shares of ZIP immediately started to spike higher and run towards its current price of $8.20 a share. If you're in the bull camp on ZIP, then I would look for long-biased trades once this stock manages to break out above some near-term overhead resistance at $8.69 a share with high volume. Look for a sustained move or close above that level with volume that's near or above its three-month average action of 441,025 shares. If that breakout triggers soon, then look for ZIP to re-test and possibly take out its 50-day moving average of $10.40 a share. On the flipside, I would avoid ZIP or look for short-biased trades if it fails to trigger that breakout soon, and then if it drops below some near-term support at $8 a share with heavy volume. A move below $8 could setup ZIP to re-test $7 to $6.50 a share in the near future.
