Thats psychology, thats why there are resistance points and support points. In this market there is also alot of nervousness around, so there are many reasons why one might sell as there are why some might sell.
To put it in perspective though, the volumes of late have been very very low, $22K on the fpo alone today so far. There is certainly no dumping happening as there is also not alot of interest.
