This was the best day so far in 2012 at the Stockholm stock exchange. When the trade closed the OMXS index was up with 2.5 percent to 333.5. It was a bit surprising since both Sandvik and Scania presented rather weak results. The background to the positive trading figures is instead believed to be the new Chinese figures which indicate a surprisingly strong growth. Also the leading stock markets in Europe were up at closing time. London with 1.9 percent, Paris with 2.1 percent and the Frankfurt stock exchange was up with 2.4 percent. (SR)
