Monday's rocket is the defense company Saab, which at lunchtime is up over 8 percent following the weekend's political discussions about increased investments in defense in Europe. This morning, the company also announced that it had received a robot order from the jointly owned German Taurus worth 1.7 billion kronor.
Saab's share has risen nearly 50 percent on the stock exchange this year.
Also trading on the plus side are bearing manufacturer SKF, up 1.6 percent, and network casino company Evolution, which has risen 1 percent.
The morning's losers are property company SBB, which is down 2.3 percent. Things are also going less well for air heat pump manufacturer Nibe and Telia, which are both down 0.8 percent.
The Swedish krona strengthened against both the dollar and the euro on Monday, driven by expectations that Sweden's defense industry will be strengthened as Europe increases its defense investments, reports news agency Bloomberg.
One dollar costs 10.67 kronor and one euro costs 11.15 kronor.
Ahead of the opening on Wall Street later today, futures trading points to rising indexes. In advance trading, Tesla is up 2.1 percent, and Alphabet, Amazon, and Meta are all up nearly 1 percent.
