When US stocks are at a time of “extreme fragility,” the earnings season has begun

US stock index-level volatility looks calm on the surface, but internal pressure is building. Under triple pressure from the geopolitical situation, expectations for monetary policy, and signals from the credit market, market fragility has risen to its highest level in recent years—just as a high-expectation, high-risk earnings season is getting underway.

UBS’s derivatives strategy team’s “Turbu-lens” market fragility indicator is currently at 0.9 (range -1 to 1), the highest level since mid-September 2025. Historically, readings like this often signal a sharp, near-term surge in the VIX. UBS derivatives strategist Maxwell Grinacoff’s team warns that this indicator points to “extreme market fragility,” with earnings season starting right now. At the same time, the team also notes that if the system-wide strategy goes all-in on leverage, the indicator “could truly reach +1.”

Elevated market expectations further amplify risk. Analysts’ forecasts for second-quarter earnings growth for S&P 500 constituent stocks are as high as 24%, and expectations for Europe’s STOXX 600 index are also 12%. Unlike prior earnings seasons, analysts have kept raising forecasts into the eve of the reporting period; the strength of their confidence also implies that, if results disappoint the market, there will be more room for downward adjustment.

VIX looks calm, but single-stock volatility is more than three times higher

Even though the VIX is at a relatively low level, this calm is misleading. Barclays strategist Anshul Gupta’s team says the VIX’s recent slide coincides with a seasonal calendar window when day-to-day price volatility typically narrows—a “brief sweet spot” with limited durability. And the start of earnings season may push the VIX back up.

More importantly, subdued index-level volatility is masking extreme internal dispersion in the market—single-stock volatility is more than three times index volatility. Grinacoff says this gap is likely to narrow during the summer; by then, whether it’s a re-pricing of monetary policy or geopolitical disruptions, index-level volatility could rise.

On hedging strategies, because diversified trading and sector rotation may keep persisting through the next several weeks of earnings, the effectiveness of hedging at the index level may be limited. Grinacoff suggests that, “single-stock options may offer better opportunities tactically.”

Oil prices and the bond market send double warnings

Oil price volatility driven by the geopolitical situation is creating persistent pressure on global equities. Brent crude has risen to just below $80 per barrel. This trajectory could keep inflation expectations elevated and keep the Fed in a wait-and-see posture. Even though changes in rate-hike expectations were limited after the release of the Fed meeting minutes, the yield on the 10-year US Treasury has quietly climbed to near the 4.6% level. Rising bond-market volatility sends a negative signal to global equity markets, or at least suppresses further upside.

Citi strategists’ team (including Alice Zheng) says positioning in the market for higher oil prices is currently skewed, with Europe especially vulnerable—because it is highly dependent on imported energy and has lower exposure to AI beneficiary assets. “If the oil price uptrend continues, the pullback in European equities could be quite significant,” the strategists wrote, “given that the market has already priced in heavily the expectation that the conflict will end.”

Credit markets don’t endorse the stock rally

The credit market’s performance is sounding a warning for the current stock market upswing. Compared with equity indexes having climbed to record highs earlier, the narrowing in credit default swap (CDS) spreads has been relatively limited. The credit market has not provided sufficient endorsement for the stock rally. As stocks have recently pulled back, the two have moved back toward alignment, but analysts believe that to support a stronger upward move in equities, the credit market will need to show clearer tightening signals.

Given the risks above, UBS suggests investors capture stock-level volatility opportunities through pair-wise correlations trades. On sectors, UBS believes the US market is best suited for pairing volatility trades in the technology, energy, and financials sectors, while for Europe it recommends energy, technology, and consumer discretionary.
