Global markets are currently recalibrating as a volatile mix of surging oil prices and skepticism toward artificial intelligence valuations triggers a widespread sell-off. According to Reuters, investors are retreating from tech-heavy portfolios while Brent crude prices have climbed to $97.60 a barrel following renewed geopolitical friction in the Middle East.
Why are tech stocks facing a sudden sell-off?
Investors are questioning the financial sustainability of the AI boom. As reported by Reuters, the tech-heavy Nasdaq index lost nearly 5% of its value late last week, ending a nine-week streak of gains. The primary concern, according to Susannah Streeter, chief investment strategist at Wealth Club, is that companies are seeking heavy funding for “eye-watering” capital expenditure plans even as interest rate expectations rise.
Charu Chanana, chief investment strategist at Saxo, notes that the market is shifting from blind enthusiasm to a demand for “clearer proof of earnings delivery, monetisation, capex discipline and funding returns.”
The pan-European Stoxx 600 index has felt the ripple effect of this tech-sector skepticism, with firms like ASML and Besi (BE Semiconductor Industries) seeing shares drop by 3.2% and 4.5% respectively.
How are global markets reacting to the oil price spike?
The rise in Brent crude—up nearly 5%—follows direct exchanges of fire between Iran and Israel. Reuters reports that this is the first such direct strike since an April ceasefire. Markets in Asia, which rely heavily on oil imports, have taken a significant hit. The South Korean Kospi index slumped by nearly 9% at one point, forcing a temporary trading suspension, with chipmakers Samsung Electronics and SK Hynix dropping 9% and 6% respectively.
The energy sector presents a stark contrast to the broader market decline. While tech firms struggle, shares in oil majors such as BP and Shell have risen, reflecting the market’s response to the potential disruption of the Strait of Hormuz, a critical shipping channel for global energy supplies.
What is the outlook for AI investments?
Analysts suggest the current market movement is a “positioning reset” rather than a complete departure from artificial intelligence technology. According to Saxo’s Charu Chanana, the AI narrative remains, but the era of “easy AI enthusiasm” may be fading as investors become more selective regarding which companies can actually monetize their expensive infrastructure investments.

When markets show high volatility, look for companies with strong balance sheets and established cash flows. As noted by Wealth Club, current concerns center on whether assets purchased today will become obsolete, making “capex discipline” a key metric for long-term investors.
