Bought PCAR toady on that second dip today, I was kicking myself yesterday for no going long at open.
Anyways, based on yesterday's action, I'm convinced it wants a gap fill before earnings. It may even retest the top. First, it's gotta get over that resistance at $87, hopefully the market gaps up tomorrow for Ponzi 401k paypday Friday.
If you trade PCAR, you may want to follow my ES1! posts, I mention it quite frequently, but don't always post plots.
