Wall Street is experiencing a seismic shift as artificial intelligence disruption fears trigger a dramatic rotation from software stocks to asset-heavy industries. The S&P 500 software sub-index has tumbled to its lowest level since April 2025, losing a staggering $1.2 trillion in market capitalization in less than a month. Meanwhile, utilities, energy, and materials stocks are suddenly back in vogue, with energy stocks gaining 23% and utilities up 9% as investors seek shelter in businesses with tangible assets.
The Great Rotation: From Capital-Light to Capital-Heavy
“All these capital-light businesses that could scale historically are also the ones that could be easily disrupted,” explains Guillaume Jaisson, European strategist at Goldman Sachs. “Capital-heavy businesses are difficult to replicate – it takes time.” This insight has led Goldman Sachs to label these buoyant sectors as “Halo” stocks: heavy asset, low obsolescence.
The numbers tell a compelling story. US software companies like Intuit, AppLovin, Gartner, and Workday have all dropped at least 40% this year. In stark contrast, power company Generac Holdings and glassmaker Corning Inc are among the S&P’s biggest gainers, while oil giants Exxon and Chevron are up more than 20% in 2026. Europe shows similar patterns, with defence and energy sector supplier Kongsberg Gruppen and oil tanker shipping company Frontline Plc both rising about 50% since January.
The Trigger: When Speculation Meets Reality
What sparked this dramatic sell-off? According to multiple sources, the flash crash began with a single speculative blog post from Citrini Research titled “The 2028 Intelligence Crisis.” Published on February 22, 2026, the post described a hypothetical scenario where AI-driven productivity gains lead to high unemployment and economic damage by 2028. Despite being labeled as “bear porn or AI doomer fan-fiction” by some analysts, the original tweet garnered 6.4 million views and sparked genuine panic among investors.
Alex Temple, a credit portfolio manager at Allspring Global Investments, describes the phenomenon as “Fobo” – fear of becoming obsolete. “It’s late-cycle behavior,” Temple notes. “A lot of people will be invested in things that they don’t know a lot about.” The software selling, he argues, was driven by vague predictions of AI disruption that investors didn’t fully understand but feared nonetheless.
The Ripple Effect Across Industries
The anxiety isn’t limited to software. Private capital giants like Ares, KKR, Apollo, and Blackstone fell more than 6% on Monday, partly due to Blue Owl halting withdrawals in one of its funds. UBS analyst Samantha Meadows points to a specific vulnerability: “Coding has become the first domain where AI demonstrably outperforms humans at scale, and as a result, the software sector has emerged as the most immediate pressure point.”
Wealth management is feeling the heat too. Fintech company Altruist developed an AI-led tool that personalizes investment strategies for financial advisers, causing double-digit declines in shares of major wealth managers on both sides of the Atlantic. Altruist CEO Jason Wenk warns the technology makes “average advice a lot harder to justify,” raising fundamental questions about the future of human financial guidance.
The Bigger Picture: Structural Shifts in Investing
This market movement represents more than just temporary panic. It reflects deep structural changes in how investors evaluate risk in the AI era. Capital-light business models were particularly sought-after in the low interest rate environment that followed the global financial crisis, as investors focused on easily scalable business models during times of easy borrowing conditions.
But the landscape has shifted. “The thing that has been working best for the last 15 years is now the most vulnerable,” says Gerry Fowler, head of derivatives strategy at UBS. Rising interest rates since the pandemic have put pressure on these valuations at a time when investment has increased in capital-intensive sectors such as defence and infrastructure.
Goldman Sachs has responded by launching a new European basket of “capital intensive” stocks, with constituents up 12% so far this year compared with a 6% gain for the broader Stoxx Europe 600. Their “capital light” basket, meanwhile, is down 2% this year.
Beyond the Hype: What Really Matters for Businesses
For companies navigating this new landscape, the question becomes: Is your business based on intangibles and intellectual property that AI could replicate or enhance? Or do you own physical assets, infrastructure, or specialized manufacturing capabilities that are difficult to duplicate?
The market’s message is clear: In an age of AI uncertainty, tangible assets provide a psychological and financial safe harbor. This doesn’t mean software is doomed – far from it. But it does suggest investors are reevaluating what constitutes durable competitive advantage in an AI-driven world.
As businesses plan for the future, they might ask themselves: Are we building something that AI could make obsolete, or are we investing in assets that will remain valuable regardless of how intelligent our algorithms become? The answer could determine not just stock performance, but long-term survival in an increasingly automated economy.
