Advanced Micro Devices designs a variety of digital semiconductors for markets such as PCs, gaming consoles, data centers (including artificial intelligence), industrial, and automotive applications. AMD's traditional strength was in central processing units and graphics processing units used in PCs and data centers. However, AMD is emerging as a prominent player in AI GPUs and related hardware. Additionally, the firm supplies the chips found in prominent game consoles such as the Sony PlayStation and Microsoft Xbox.

What to Watch
Holds across regimes
Correlation is similar when markets rise (+28%) and fall (+38%) — reliable in both directions.
Regime-dependent
The correlation has flipped sign across time windows — not reliable as a standalone signal.
