The Warsaw Stock Market started Thursday session positively, with Its largest companies, the WIG20, rising 0.59 percent shortly after the opening bell. Poland’s copper giant KGHM drove the index up this morning rising as much as 2 percent, the biggest gain seen so far at today’s session. Other indexes, however, have stood still, so they could still move up later in the day. Investors, however, are now holding their collective breath before the US foreign trade figures come out later today.
