UBS HOLT Highlights Extreme Tech Volatility and Funding Gaps
UBS’s HOLT research unit indicates that volatility in the global technology sector has risen to its highest level since the dot‑com crash, as investors reassess whether AI‑driven cash‑flow returns of hyperscalers and semiconductor companies can be sustained.
The analysis points to mounting strain from AI infrastructure spending; heavy data‑centre investment is eroding asset efficiency at major hyperscalers even though profit margins remain stable, driving down cash‑flow returns on investment (CFROI) through 2028.
UBS estimates that the top five hyperscalers—Microsoft (NASDAQ:MSFT), Meta (NASDAQ:META), Alphabet (NASDAQ:GOOGL), Amazon (NASDAQ:AMZN) and Oracle (NYSE:ORCL)—face a combined $227 billion funding gap next year against their operating and financing commitments.
Historically, of roughly 650 large capital‑expenditure surges since 1998, 60% were followed by a permanent decline in CFROI, with the effect most pronounced among companies whose starting returns were already elevated.
In the semiconductor segment, returns have roughly tripled to around 30%, a performance level matched by fewer than 1% of companies since 1990. UBS notes that current valuations assume these elevated returns will persist for five years, a scenario that runs counter to typical competitive dynamics.
The report cites Chinese AI developers DeepSeek and Moonshot as evidence that “economic moats” in the sector may not be unassailable, given China’s tendency to prioritize market share over profitability.
Software, enterprise data and services stocks have already seen valuations reset, with aggregate price‑to‑book ratios down about 40% over the past 18 months on fears of AI‑driven disruption.
UBS found that 80% of stocks that derated by a comparable amount failed to regain prior valuation levels within a decade.
Looking beyond the technology sector, UBS points to Value and Low Volatility as the strongest‑performing style factors during past tech‑led selloffs, with Value outperforming in all six major episodes since 2004 and Low Volatility in four. The bank warns, however, that both approaches carry limitations in the current environment: Value’s traditional link to the economic cycle has weakened since 2023, while Low Volatility stocks tend to underperform outside of selloff periods unless paired with strong underlying fundamentals.
