Mobile Stocks Hurting This Week

Whats going on with the stock market? November was looking great until this week. The market took a fat dump and all I see is red figures. Most of the mobile stocks are taking a beating as well. Could this because of Palm's latest woes (delayed launch of Treo 750 and pending patent infringement lawsuit) or just market adjustment?

In any case, mobile stocks are down and here is where they are today:

MOT $21.53 (-1.4%)
PALM $14.33 (-6.8%)
RIMM $132.2 (-3.0%)
NOK $20.06 (-1.2%)
