This stock has been trending down since its January high of $4.38 to its recent low of $3.63 a share. Since hitting that low, TLAB has found some buying interest since the stock has spiked back up close to its 50-day moving average of $3.89 a share. If you're bullish on TLAB, then I would look for long-biased trades once it sustains a high-volume move or close back above its 50-day moving average of $3.89 a share. Look for volume on that move that's near or well above its three-month average volume of 2,536,648 shares. If we get that action soon, then I would add to any long positions in TLAB once it takes out its 200-day moving average of $4.02 a share with high-volume. I would simply avoid any long trades in TLAB if it fails to trigger that high-volume move back above its 50-day and 200-day moving averages, and then drops below some major support zones at $3.63 to $3.62 a share with heavy volume. A high-volume move below those support zones would not be a good technical sign for this stock since it's held those levels since mid-2011.
