Look for a sustained move or close above those levels with volume that registers near or above its three-month average action of 334,422 shares. If that breakout triggers soon, then RBCN will set up to re-test or possibly take out its next major overhead resistance levels at its 200-day of $8.68 to $9.50 a share. Any move above $9.50 a share will then put $10 to $10.77 into focus for shares of RBCN. Traders can look to buy RBCN off any weakness to anticipate that breakout and simply use a stop that sits right around some near-term support at $6.20 to $6 a share. One could also buy off strength once RBCN clears those breakout levels with volume and then simply use the same stop that sits right below its 50-day moving average of $6.40 a share. This stock is a favorite target of the short sellers, since its current short interest as a percentage of its float is 20.9%. If that breakout triggers soon, then watch for a short-squeeze to develop that could send this stock flying higher in a very short timeframe.
