Thursday trading session on PSE was volatile again. There were only three names with real volume; CEZ, (502 CZK, 2,18%) O2 CR and Komercni banka. CEZ was better offered with active international investors. O2 CR spiked up just before the close. Unusual strong international buying interest while locals were on the sell side. Komercni banka managed to finish higher after weak opening and nervous trading. (463 CZK, 2,66%) was supported by an upgrade to Buy from Hold at (16 USD, -0,85%). It seems like some players realized (4 393 CZK, 9,14%) is cheap and pushed the stock almost 10% up from the oversold territory. The most of the volume was done via X-trades.
