Another under-$10 stock that could be a buying opportunity at current levels is biotechnology company Threshold Pharmaceuticals ( THLD). This stock is one of the top stocks in 2012, with shares up over 390%. If you take a look at the chart for Threshold Pharmaceuticals, you'll notice that this stock made a monster move during the last two months, from $1.27 a share to its recent high of $9.07 a share. During that run-up, the stock has gapped up a number of times with huge volume, and it's triggered a bunch of breakouts with volume. That said, the stock has finally seen the sellers take the upper hand since it's just pulled back from $9.07 to around $6 a share. If this stock can now hold above its 50-day moving average, then it could be setting up for a solid buying opportunity if the bulls return. >>8 Stocks Under $10 Making Big Moves Market players should now look for long-biased trades in THLD if this stock can stop its near-term downtrend and find some buying interest as it approaches its 50-day moving average of $5.72 a share. If that level gets hit, and it doesn't get violated with heavy volume, then we could catch a sizeable bounce in the near-term. That bounce would also be confirmed if THLD holds the 50-day and then breaks out above some near-term overhead resistance at $7.08 a share. Look for volume on a move over $7.08 that's near or well above its three-month average volume of 3.7 million shares. I would avoid any long trades in THLD if it loses that 50-day with heavy volume, but I would continue to look for long trades as long as the 50-day holds and it's trending above it with strong upside volume flows. Keep in mind that during the past few months and change THLD has yet to violate its 50-day, so look for that trend to continue of $5.72 holds up.
