The history of warfare includes some major milestones that changed how war was fought. A recent announcement by Ukraine may represent just the latest in that long, bloody list.

One of the hottest themes in investing this year has been Space. Partly due to its tie-in with the broader Defense theme, and more recently, thanks to investor excitement over the upcoming SpaceX IPO, space investing as a thematic opportunity has been capturing attention and investor dollars.

Artemis II's record-breaking mission boosts confidence in space plays, with ETFs like ARKX poised to benefit from the long-term industry growth trend.

With actively managed exchange-traded funds (ETFs) growing increasingly popular relative to traditional passive funds, investors may find that these ETFs can give an advantage when it comes to highly timely investment issues, such as those related to the ongoing Iran war.

Recent shifts in warfare toward autonomous, low-cost drones support the fund's thematic focus, yet ARKX's execution and transparency remain concerns.

An unfortunate reality facing the world in 2026 is rising geopolitical risk. The year kicked off with a U.S. attack on Venezuela, with the Russian war in Ukraine entering a fifth calendar year.
