Despite the Iran war disrupting global supply chains and consumer confidence, major corporations have collectively gained over $5.4tn in market value since late February, up 4.2%. Tech giants and semiconductor firms like Intel and TSMC have led the rebound, with AI optimism offsetting Middle East tensions. Investors flocked to tech’s ‘certainty of earnings,’ as semiconductor companies with over $10bn market caps surged 26%, adding $3.7tn in value. The sector’s resilience contrasts sharply with declines in energy firms like ExxonMobil, which lost $28bn due to Gulf operations disruptions.

Semiconductor stocks outperformed during the crisis, with analysts attributing their rise to the AI boom’s perceived durability. Saudi Aramco gained $144bn, leveraging a 50% oil price spike, while smaller Middle East-exposed firms like Equinor rose 24%. Conversely, companies reliant on Gulf infrastructure, such as Shell, face multibillion-dollar repair costs. Consumer sectors also faltered as shipping bottlenecks raised costs, prompting warnings from Procter & Gamble and Kimberly-Clark about price hikes.

Defense contractors underperformed despite heightened demand, as investors questioned their capacity to scale production amid existing supply constraints. Meanwhile, mining firms like Agnico Eagle suffered steep losses after gold prices fell from 2023 peaks. The divergence highlights how AI-driven tech valuations have decoupled from broader economic fragility, with LVMH and automakers like Volvo Cars cited as casualties of reduced demand and logistical challenges.

The rebound underscores a broader market preference for AI’s ‘real, durable investment cycle,’ per analysts. While energy and consumer sectors grapple with war-driven volatility, tech’s AI narrative has fueled a faster recovery than post-Ukraine or pandemic rebounds. BP and TotalEnergies rose 14-16%, but the stark contrast between winners and losers reveals how geopolitical shocks amplify sectoral divides.
