The Complete Semiconductor Playbook — AI Supercycle 2026 The AI trade is no longer one ticker. It’s a full stack. Here’s every layer: 💾 MEMORY $MU · $WDC · $STX · $SNDK · $AMAT · $LRCX → HBM4 = the new oil. Not a commodity anymore. Strategic infrastructure. 🔌 CONTROLLERS $RMBS · $SIMO · $ATOM · $MCHP · $ADI · $TXN → The traffic cops of every AI system. Overlooked. Undervalued. Critical. 📦 PACKAGING / TESTING $AMKR · $FORM · $CAMT · $ONTO · $COHU · $ACMR → CoWoS. HBM stacking. Chiplets. This is where chips become systems. 🧠 NEXT-GEN MEMORY $MRAM · $GSIT · $NVEC · $NLST · $CEVA → Beyond DRAM. Early-stage. Asymmetric upside when the cycle arrives. 🌐 OPTICAL / INTERCONNECT $LITE · $AAOI · $COHR · $CIEN · $MRVL · $GLW · $MTSI · $TSEM · $POET · $LWLG · $FN → The hottest sub-sector in semis right now. 800G → 1.6T.
