The Czech PX Index strengthened during the day, but got hit after weak US GDP data and closed in negative territory. Total traded volumes were well above the long-term averages, when the most actively traded stocks were CEZ, Zentiva, Telefonica O2 CR and Komercni banka. We saw profit taking on CEZ, Zentiva and ECM. CEZ could not hold the CZK 1,000 level and fell below this milestone before the end of the session. Telefonica O2 CR increased and was the best performing stock in SPAD, despite it lost some of its intraday gains. Orco closed higher by more than 0.6% on news about overtaking state GSG in Berlin.
