If you're bullish on ATU, then I would wait until after its report and look for long-biased trades if this stock manages to break out above some near-term overhead resistance at $29.65 a share with high volume. Look for volume on that move that registers near or above its three-month average action of 553,982 shares. If that breakout triggers, then ATU will set up to re-test or possibly take out its 52-week high of $31.33 a share. Some possible upside targets above that 52-week high are $33 to $35 a share. I would avoid ATU or look for short-biased trades if after earnings it fails to trigger that breakout, and then drops back below both its 50-day at $28.04 a share and its 200-day at $27.72 a share with high volume. If we get that move, then ATU will set up to re-test or possibly take out its next major support levels at $26.50 to $25.38 a share.
