We recently published a list of 13 Best Defense Stocks to Buy According to Billionaires. In this article, we are going to take a look at where RTX Corporation (NYSE:RTX) stands against other best defense stocks to buy according to billionaires.
Defense stocks wobbled over the past week after a contentious meeting at the Oval Office between President Trump and the visiting Ukrainian leader, Volodymyr Zelensky as investors hoped for the US-Ukraine minerals deal to be signed.
The sector has struggled since Trump’s return to the White House, amid mixed statements on military expenditure throughout his campaign and the early days of his second stint. Shares fell sharply on February 13 after the President hinted at cutting defense spending in the future. The creation of DOGE is also reshaping investors’ views of the industry.

In contrast, European defense stocks have rallied this year as governments faced pressures to increase military expenditure. Several stocks registered double-digit growth during the week of March 3, with some even reaching record highs. Investor sentiment picked up after the European Summit in London, where leaders from the EU and NATO met to express their support for Ukraine, following the recent Zelensky-Trump spat.
Washington has repeatedly called for European countries to spend more on defense, while stressing that the US could no longer foot the bill. EU leaders met in Brussels this Thursday 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.
European countries are also ramping up defense on an individual-level. A conservative victory in Germany, signaling the shift to the right in Berlin, is also adding to the momentum. According to a Reuters report, parties in talks to form the nation’s next government are already considering setting up a defense fund. Friedrich Merz, Germany’s next chancellor-in-waiting, has also vowed to relax the country’s strict borrowing rules.
Peter Schaffrik, Global Macro Strategist, at RBC Capital Markets stated the following on the ongoing situation:
It is an inflection point and Europe realises it needs to do the heavy lifting. The German elections have opened the door for more spending. The whole Zelensky-Trump meltdown has fast forwarded everything.
