Scenario Background
Semiconductor stocks (SMH) are highly cyclical and serve as a leading indicator for both the technology cycle and broader industrial economy.

SMH has had multiple sustained outperformance periods: 1999 (tech bubble leadership), 2017 (crypto GPU cycle), 2019-2020 (COVID tech acceleration), and 2023-2024 (AI boom). The 2023-2024 cycle saw Nvidia singularly drive much of the rally, with SMH rising 200%+ from October 2022 lows. Prior cycles saw broader chip leadership. The 1999 cycle preceded significant tech drawdowns; 2017 and 2019 preceded milder corrections.

- •Semi capex announcements (TSMC, Samsung, Intel)
- •Memory pricing bottoming and rising
- •AI infrastructure deployment accelerating
- •Traditional semi end-markets (autos, industrial) recovering
