UBS raises its recommendation for defense company Saab to buy from neutral. The target price is raised significantly to 525 kronor from 250. The share rises 3.1 percent to 391.95 kronor last paid.

The Swiss bank believes Saab is well positioned to benefit from increased defense spending and raises its recommendation to buy despite the recent price increase.

"We believe the ground combat portfolio, including the Carl Gustaf recoilless rifle, and the surveillance portfolio, including the Giraffe air defense radar, are very well positioned to benefit from sales increases in the near term," it said in an analysis.

Meanwhile, the recommendation for Italian defense company Leonardo is lowered to neutral from buy. The target price is raised to 50 euros from 31.

The company is expected to benefit from the major defense build-up underway in Europe. At the same time, the recommendation is lowered due to the recent price increase.

"We believe that management's actions over the past two years, including the dividend increase and efforts to reduce exposure to the B787, have improved the company's returns from the perspective of minority shareholders, but that these efforts are now reflected in the share price," UBS writes.
