If you're bullish on JDSU, then I would wait until after they report and look for long-biased trades if this stock can manage to break out above some near-term overhead resistance at $11.30 a share, and then above its 200-day moving average of $11.59 a share with high volume. Look for volume on that move that hits near or above its three-month average action of 4,977,950 shares. If we get that move, then look for JDSU to re-test or possibly take out its next major overhead resistance level at $13.55 a share. I would avoid JDSU or look for short-biased trades if after earnings it fails to trigger that breakout, and then drops below its 50-day moving average of $10.02 a share with heavy volume.
