A Stock Trader’s Guide to a Fractured Economic World

Investors are set to pour more money into defense, energy and technology stocks as the Middle East war forces governments to prioritize security and become more self reliant.

Wall Street has for years rewarded companies at the vanguard of globalization, while many countries neglected critical infrastructure, supply chains and resources. That era is now over, according to investors, who say the Iran conflict is accelerating economic changes prompted by the coronavirus pandemic, Russia’s invasion of Ukraine and America’s trade war.

“I suspect a lot of people are still in denial that the world has changed,” said John Wyn-Evans, head of market analysis at Rathbones Group Plc. “Covid-19 and Russia-Ukraine were wake-up calls, but we seem to have hit the snooze button. The alarm has gone off again now.”

The war has increased demand for the dollar and US assets, but stock pickers are also hunting for companies that will play key roles in the move toward more secure supply chains and benefit from investment in artificial intelligence, green energy and defense. So far in 2026, energy, materials, utilities and industrials are the top-performing sectors in the MSCI World Index.

“It’s a structural reset in how the global system works,” said Sahil Mahtani, director at Ninety One Plc. “Globalization isn’t ending — but it’s no longer happening on easy mode. The assumptions that defined the last 30 years are now being challenged all at once.”
