From a technical perspective, ALXA is currently trending above both its 50-day and 200-day moving averages, which is bullish. This stock recently gapped down from a high of $6.46 to around $4.75 a share with big downside volume. Following that move, shares of ALXA went on to hit a recent low of $4.62 a share, but the stock has now started to rebound and move within range of triggering a near-term breakout trade. If you're in the bull camp on ALXA, then I would look for long-biased trades as long as it's trending above its 200-day moving average at $4.66, and then once it breaks out above its gap down day high of $5.44 with high volume. Look for a sustained move or close above $5.44 a share with volume that hits near or above its three-month average action of 815,923 shares. If that breakout triggers soon, then ALXA will set up to re-test or possibly take out its recent high of $6.46 a share. Any move above that level will then put $7.60 into focus for shares of ALXA.
