PERI I also believe the office closing and layoffs were definitely perceived by the market as negative and caused the 10%+ drop this week.
Why it was this low in the first place is another thing. I guess it is like why was PCMI in the 6's a couple of weeks ago? Who knows? I guess selling begets selling sometimes.
I am fully expecting an after earnings rally for PERI similiar to what PCMI had. IMHO
