If you're in the bull camp on TRIP, 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 its 50-day moving average of $74.02 a share to more resistance at $75.43 a share with high volume. Look for volume on that move that hits near or above its three-month average volume of 1.82 million shares. If that breakout hits, then TRIP will set up to re-test or possibly take out its next major overhead resistance levels at $79.89 a share to its 52-week high at $82.19 a share. Any high-volume move above those levels will then give TRIP a chance to tag $85 to $90 a share. I would avoid TRIP 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 $71.60 to $68.11 a share with high volume. If we get that move, then TRIP will set up to re-test or possibly take out its next major support levels at $62.50 to its 200-day moving average of $60.03 a share.
