One more under-$10 stock that's trading within range of triggering a major breakout trade is Alphatec ( ATEC), a medical technology company focused on the design, development, manufacturing and marketing of products for the surgical treatment of spine disorders, with a focus on products that treat conditions that affect the aging spine. This stock is off to a slow start so far in 2012, with shares up just 6.5%. If you take a look at the chart for Alphatec, you'll notice that this stock has been trending sideways for the last three months, with shares moving between $1.50 on the downside and $1.90 on the upside. Shares of ATECH have recently started to bounce strongly off its 50-day at $1.68 with heavy volume, and it's also starting to flirt with its 200-day at $1.86 a share. That move is quickly pushing ATEC within range of breaking out topside of its sideways trading pattern. Traders should now look for long-biased trades in ATEC once it manages to break out above some past overhead resistance at $1.90 a share with high volume. Look for a sustained move or close above $1.90 with volume that registers near or above its three-month average action of 132,369 shares. If that breakout triggers soon, then ATEC will setup to re-test or possibly take out its next major overhead resistance levels at $2.20 to $2.40 a share, or possibly even $2.80 to $3.50 a share. One could look to buy ATEC off weakness to anticipate that breakout and simply use a stop that sits just below its 50-day around some near-term support at $1.68 a share. One could also buy off strength once ATEC clears $1.90 with high volume and then simply use a stop at around $1.75 a share. Keep in mind that any move above $1.86 will push ATEC back above its 200-day moving average, which is technically bullish price action.
