If you're in the bull camp on FDO, 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 levels at $63.35 to $64 a share with high volume. Look for volume on that move that registers near or above its three-month average action of 1,597,440 shares. If that breakout triggers, then FDO will set up to re-test or possibly take out its 200-day moving average at $65.60 or its 50-day moving average at $66.45 a share. I would simply avoid FDO or look for short-biased trades if after earnings it fails to trigger that breakout, and then drops back below some key near-term support levels at $61.90 to $60.86 a share with high volume. If we get that action, then FDO will set up to re-test or possibly take out its next major support level that sits just below $58 a share.
