If that breakout hits soon, then JCP could easily rip higher towards its next major overhead resistance levels at its 50-day moving average of $15.74 to $16.75 a share. If Ackman were to sell his stake, then JCP could see an even bigger squeeze back towards its next major overhead resistance levels at $20 to $23 a share. Any high-volume move above $23 will then give JCP a chance to tag its October high of $27 a share.
