The Stockholm Stock Exchange has thus recorded three trading days in a row with clearly rising prices.
The real estate company SBB, which announced a major deal with partly owned PPI on Tuesday evening, surged 19.7 percent as a result.
Another winner was Munters, a supplier of air cooling units for data centers, which received an order worth SEK 2 billion from an American customer. The stock climbed 14.9 percent on the stock exchange.
Among the most traded stocks on the OMXS30 list, happy faces are noticeable for the four major banks, which rose between 1.1 to 1.4 percent.
But the biggest gains among the heavyweights were recorded by mining company Boliden, up 2.4 percent. Engineering company SKF went furthest in the opposite direction, down 1.5 percent.
At the close in Stockholm, the stock exchanges in Frankfurt, London and Paris were all in the red.
In New York, the trend is mixed with one of the major indices up, one down and one trading unchanged.
Including Wednesday's rise, the Stockholm Stock Exchange has risen 8.1 percent since the turn of the year.
