Investment bank Citi has upgraded its recommendation for Saab to neutral from sell, while adjusting its price target to 527 SEK from 516 SEK following the recent downturn in the defense sector.

Concurrently, Germany's Rheinmetall has seen its rating raised from neutral to buy.

The bank suggests that concerns regarding a potential peace agreement in Ukraine and the financing of increased European defense spending are overblown, according to EFN, which has reviewed the research note.

'We believe that Russia is likely to remain a threat to Europe,' Citi wrote in the analysis.

Saab shares are trading flat in early deals, while Rheinmetall is up just over 1 percent.
