Can anyone here please tell me why this fund (and several others I've researched, including ARTMX, DODGX, etc) seem to exhibit historical price drops in the last 2 weeks fo December when the indices did not have such a bad day? For example:
27 Dec 2004, 3.48% drop (DOW down 0.23%);
27 Dec 2005, 3.56% drop (DOW up 0.17%);
26 Dec 2006, 8.70% drop (DOW up 0.83%);
26 Dec 2007, 11.85% drop (DOW down 1.42%).

Am I missing something? Not all funds have this historical pattern.
Thanks in advance for any insight.
cheers.
