From a technical perspective, ZZ is currently trading above its 50-day and 200-day moving average, which is bullish. This stock flirted with a major breakout trade Wednesday when shares briefly traded above some major past overhead resistance at $2.02 to $2.15 a share on monster volume. Volume registered 2.57 million shares versus its three-month average volume of 403,365 shares. That said, the stock failed to close above those breakout levels, and it closed a bit off its daily high of $2.23 a share. If you're bullish on ZZ, then I would look for long-biased trades off a sustained high-volume move and close above $2.02 to $2.15 a share. Look for volume on any move above those levels that's near or well above 403,365 shares. If we get that action soon, then look for ZZ to make a run at its next major overhead resistance levels at $2.78 to $3.11 a share.
