Citable research brief

Core conclusion · Tlines extraction

UBS CIO keeps a constructive stance after a risk-off session: the Nasdaq fell 2.6% and the SOX 6.7% on AI capex and financing worries, while Brent rose 4% to a five-month high of USD 113/bbl and the 10-year Treasury yield fell nearly 17bp to 4.95%. Robust earnings, strong AI demand and attractive bond yields support equities; exposure to capital-intensive neoclouds stays limited in favour of hyperscalers and quality bonds.

Key arguments

Robust earnings, not geopolitics, should keep supporting equities; market weakness stayed concentrated in technology, with two-thirds of S&P 500 constituents up and the equal-weighted index +0.8%.
Earnings strength is broadening: Q3 S&P 500 EPS growth of 28% year over year, with semis contributing roughly half and cloud revenue growth accelerating from 48% to 58%.
Fixed income is rated Attractive: yields would need to rise about 246bp (2y), 109bp (5y) and 63bp (10y) to erase one year of income, which is seen as unlikely.
Higher oil is a headwind but the energy system is adapting (Middle East exports near 80% of pre-conflict levels); the GDP hit should fade over 12 months absent a sustained spike.

Key numbers

Nasdaq one-day decline: 2.6%
Philadelphia Semiconductor Index decline: 6.7%
Brent crude price: USD 113/bbl (+4%)
10-year Treasury yield: 4.95% (-17bp)
Q3 S&P 500 EPS growth forecast: 28% YoY

Main risks

Intensified Iranian attacks on shipping in the Strait of Hormuz and no Russia-Ukraine ceasefire on energy infrastructure could push oil higher.
Funding pressures and execution risk at neoclouds may compound each other in the capital-intensive AI buildout.
Longest-maturity Treasuries carry fiscal and issuance concerns; higher oil risks both growth and inflation.

Corresponding source evidence

We expect third-quarter S&P 500 earnings per share to grow 28% from a year earlier, driven by AI demand, an improving industrial cycle, and resilient higher-income consumers.
Semiconductor profits are expected to contribute around half of that growth, while average cloud revenue growth is forecast to accelerate from 48% in the June quarter to 58% year over year in the September quarter.
Beyond technology, nine consecutive months of expansion in the new-orders component of the ISM Manufacturing Index and 6% year-over-year growth in September US retail sales support our view that cyclical parts of the market should also see robust earnings growth.
