RE: Short interest Probably, tax loss selling. Should only continue for a few more days. Some people could have got in around the 1.70 to 2.40 range and feel a little burned. You never know, even though AMB looks to be a company that can spin out huge cash flow, some times for some unknown reason they trade at low valuations. I owned Neo Materials back in the day, traded at 6x PE but had relative growth numbers and a ROE that was in line with apple. Sadly its trapped in a horrible company called molycorp. :( sad face.
Anyways, I think its just volatile, there was a lot of positive news that kept things moving up the last three months. Now we don't have anything, and its always quiet for the hollidays.
