The Stockholm Stock Exchange posted solid gains on Thursday, mirroring the performance of leading European markets. Further support for the market came from data showing that U.S. inflation in November rose less than expected. In the news flow, Skistar reported results.

Thursday saw a series of interest rate decisions. Sweden's Riksbank left its key interest rate unchanged at 1.75 percent and signaled that the rate is expected to remain at this level for some time. Both Norway and the ECB also kept their rates unchanged. The Bank of England cut its key rate by 25 basis points to 3.75 percent. All four rate decisions were in line with analysts' expectations.

At the close, the OMXS30 index was up 1.18 percent at 2,827.91. Shares worth approximately 20.0 billion kronor were traded on the Stockholm Stock Exchange.
