This stock has been trending lower for the last six months, with shares off by 19.8%. If you take a look at the chart for Affymetrix, you'll notice that this stock has been trending sideways for the last three months, with shares moving between $3.72 on the upside and $2.96 on the downside. That sideways trading pattern came after the stock gapped down with big volume last October from around $4.50 a share. Shares of AFFX have recently started to trend back above its 50-day moving average of $3.26 a share and it's quickly moving within range of triggering a near-term breakout trade. Traders should now look for long-biased trades in AFFX if it manages to break out above some near-term overhead resistance levels at $3.62 to $3.72 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 action of 681,000 shares. If that breakout hits soon, then AFFX will set up to re-fill its previous gap down zone from last October that started near $4.50 a share. Any high-volume move above $4.50 to $4.61 would then put $4.80 to $5.20 within range for shares of AFFX. Traders can look to buy AFFX off any weakness to anticipate that breakout and then simply use a stop that sits just below its 50-day moving average of $3.26 a share. One could also buy AFFX off strength once it clears those breakout levels with volume and then simply use a stop that sits just below $3.40 a share.
