Saab came under pressure on Monday after Citi reiterated its sell recommendation and Dagens industri labeled the defense company with a sell tag in its "Stock of the Week" column.

In Citi's case, the bank warns of Saab's stretched valuation compared to its competitors, according to Bloomberg News.

The bank assesses that the expected profit growth, especially after 2030, is unlikely to justify the current share price.

The analysis firm also notes that Saab is well-positioned for European rearmament and boasts strong leadership.

Dagens industri's recommendation is also based on Saab's high valuation. The newspaper argues that the company simply cannot generate the cash flows required to justify its current market value.

Saab's stock initially dropped by nearly 4 percent, but has since recovered part of the loss and is, at the time of writing, down 2.5 percent.
