Resistance at 87.50

[ellerslick]

So why is PPS plummeting all of the sudden? Are the shorts attacking?

Traded very stable at $90 over 650,000 shares then on low volume drops off the cliff for $2.50 .  I think it is the market makers, they have been letting this happen for years but not sure, maybe a programed trade with little sells all the way down.  I do know this happens when volume drys up. Seen it way to many times.
