Report Summary
Semiconductors now account for 12% of global market cap (up from 2.7% in 2022) and have directly driven 51%, 55% and 40% of YTD market returns in the US, EM and Japan respectively. UBS argues the current cycle is more similar to early 1999 than Q1 2000, with supply-side constraints, disciplined capex, and hyperscaler stability providing structural support. The team favors memory names, cheapest-in-class semis, and TSMC as a natural monopoly.
Key Takeaways
- Semis are now 12% of global market cap and have accounted for 51% of US market returns YTD; Philadelphia semi index is up 77% from lows, a move seen only twice before (1998 and 2000)
- UBS sees current environment as early-1999-like: all 7 preconditions for a bubble are in place but peak conditions (credit spread rise, earnings roll-over, central bank tightening) are absent
- Hyperscaler share prices stabilized post-Q1 results, reducing risk of capex cuts that would hit semis; top 11 hyperscalers have 2026 capex of $874bn in line with cash flow
- Supply-side constrained cycle: TSMC capex up only 80% since pre-Gen AI, memory capacity can only increase 30% in 2026-27, with 3-year fab build lead times
- Memory cycle peak pushed back to Q2 2028; cumulative FCF yield of Samsung, SK Hynix and Micron from 2026-2028 is 53%, 50% and 26% respectively
- If semis and software are the new oil, semis revenue could rise to 2-3% of GDP by 2030, implying a TAM of $3trn and a P/E of 16x on 2025 margins
Why This Report Matters
Semiconductors have become the single largest driver of global equity returns; UBS's framework suggests further upside remains, particularly in memory and supply-constrained segments, despite elevated valuations.
