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.

Lam Research is one of the largest semiconductor wafer fabrication equipment manufacturers in the world. It specializes in deposition and etch, which entail the buildup of layers on a semiconductor and the subsequent selective removal of patterns from each layer. Lam holds the top market share in etch and holds the clear second share in deposition. It is more exposed to memory chipmakers for DRAM and NAND chips. It counts as top customers the largest chipmakers in the world, including TSMC, Samsung, Intel, and Micron.
What to Watch
Tighter in drawdowns
Pair moves more tightly when both fall (+71%) than when both rise (+36%) — typical risk-off behaviour.
Mostly stable
Correlation drifts a little but stays in the same neighbourhood.
Time Series
Time-Shifted Correlation
See how correlation changes when one series is offset in time. A taller bar at a non-zero shift means the two move together better when one leads the other — that's a potential lead/lag signal.
