(Pavel Růžička) The PX-50 rebounded from Monday's plunge yesterday, but volumes were only light. The market moved along with all other European markets and for second day it has shown good correlation with the big bourses; this has not always been the case. SPT Telecom led the rise, pushed by some genuine foreign buying. ČEZ and Unipetrol advanced more thanks to short-covering than anything else. Today, we think the market is going to be vulnerable again after stocks fell overseas.
