If you're in the bull camp on BBY, then I would wait until after its report and look for long-biased trades if this stock manages to break out above its 52-week high at $44.66 a share (or Monday's intraday high if higher) with high volume. Look for volume on that move that hits near or above its three-month average volume of 5.89 million shares. If that breakout hits, then BBY will set up to enter new 52-week-high territory, which is bullish technical price action. Some possible upside targets off that breakout are $55 to $60 a share. I would avoid BBY 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 $42 to its 50-day at $40.49 a share with high volume. If we get that move, then BBY will set up to re-test or possibly take out its next major support levels at $38 to $34 a share.
