This article looks at the defense stocks that are declining this week.

European defense stocks have rallied this year, with several companies in the sector registering double-digit returns, and some even reaching record highs, as regional capitals unlock billions to supercharge their militaries.

The United States has repeatedly called for Europe to spend more on defense while stressing that Washington could no longer foot the bill. EU leaders met in Brussels earlier this month to discuss the ‘ReArm Europe Plan’, which will allow the bloc to mobilize funds up to $860 million through bonds and relaxed rules on borrowing and spending.

A conservative victory in Germany has further added to the momentum. Last week, the country’s parliament voted in favor of a historic fiscal package, which includes reforms to long-standing debt policies to allow for higher defense spending.

Several Asian contractors are also benefiting from Europe’s defense splurge. A leading aerospace and defense company in South Korea has gained over 92% year-to-date, driven by demand for weapons from NATO countries like Poland and Romania. On March 20, The Economic Times reported a 20% increase in India’s defense and shipbuilding stocks, in response to Germany’s big military plans.

In contrast, America’s defense sector has wobbled this year, due to uncertainty around the country’s future military expenditure. The creation of DOGE has also reshaped investors’ views of the industry. While Trump’s pivot on Ukraine has helped fuel the defense industry elsewhere, American stocks in the sector have lagged behind and failed to capitalize on the global rally.

According to a Financial Times report on February 24, shares of the six largest American defense companies had fallen 4% under Trump’s second term. Whereas, Europe’s top defense groups returned gains of around 40% during the same period.

Despite a grim outlook, Citi analyst, Jason Gursky, is urging investors that this is the right time to buy American defense stocks. He argues that as long as the global threat environment remains and the United States maintains its leadership role, regardless of whether it is as a sole superpower or as a power in multi-polar world order, defense spending is expected to remain robust, which would benefit stocks in the sector.

With that said, let’s now head over to the list of defense stocks that are declining this week. Please note that the stocks listed are based on one week’s performance. Our analysis does not reflect the prospects of the company.
