Questions about investment concepts

Each concept owns a decision task rather than a keyword: define the exposure, trace the causal chain, identify the companies whose results validate it, and state the evidence that would weaken it.

01 Which companies represent AI Advanced Chip Packaging? AI Advanced Chip Packaging · AI advanced chip packaging is the back-end that builds AI accelerators: CoWoS, HBM stacking, and hybrid bonding, from TSMC and Amkor to Hanmi and Besi.
02 Why do AI servers need more MLCCs? AI Capacitors (MLCC) · AI capacitors are the MLCCs that power AI servers; an AI server uses many times more than a traditional one. Led by Murata, Samsung Electro-Mechanics, and TDK.
03 What is the CPU-to-GPU ratio in an AI rack? AI CPU · The AI CPU concept covers the host and server CPUs that orchestrate AI accelerators in the agentic era: NVIDIA Vera and Grace, AMD EPYC, Intel Xeon, and Arm.
04 Why is AI driving nuclear power demand? AI Electricity & Nuclear SMRs · AI's power crunch is reviving nuclear. The AI electricity and SMR theme covers NuScale, Oklo, Constellation, and the firms powering data centers.
05 Why does custom silicon rise alongside the GPU for inference? AI Inference Infrastructure · AI inference infrastructure is the serving side of AI: the chips, clouds, networking, and power that run trained models in production, from NVIDIA to Vertiv.
06 Why run AI on the device instead of the cloud? AI On-Devices · AI on-device runs AI locally on phones, PCs, and edge hardware using on-chip NPUs, from Qualcomm and Apple to Arm, Samsung, and Micron.
07 Why now? Is this a memory supercycle? Asia Memory Semiconductor · How Korea, Japan, and Taiwan came to dominate DRAM, NAND, and HBM, and why the 2025-2026 AI memory supercycle runs through ten Asian companies.
08 Why now? A memory supercycle meets a self-sufficiency push? China Memory & Storage · China's drive to make its own DRAM and NAND: the CXMT and YMTC IPOs and the listed proxies GigaDevice, Montage, Longsys, and Ingenic.
09 Why now? What is the thesis for global space technology? Global Space Technology · Global space technology is the worldwide space theme: about 30 developed-market companies from Rocket Lab and Viasat to Avio, MDA Space, and Astroscale.
10 Why is custom silicon (the TPU) the center of the chain? Google (Alphabet) AI Value Chain · The Google (Alphabet) AI value chain lets investors own Google's AI supply chain (TPUs, foundry, optical, networking, servers) rather than just Alphabet stock.
11 Why HALO matters now? Heavy Asset Low Obsolescence (HALO) · HALO covers U.S.-listed physical-economy companies whose value sits in real assets like mines, railroads, and billboards that AI cannot easily copy or replace.
12 Why does the value chain matter now? Hyundai Motor Robotics Value Chain · How Hyundai Motor Group built a vertically integrated robotics value chain, from Boston Dynamics and Atlas down to the Korean affiliates that supply the parts.
13 Why are Korean factories the marginal supplier? Korea AI Power Infrastructure · How Korean transformer, cable, ESS, and fuel-cell makers became the marginal suppliers of the hardware AI data centers run on, and how to invest in it.
14 Why is Korea central to AI memory? Korea AI Semiconductor · Korea AI Semiconductor groups Korea's AI memory and packaging leaders: Samsung, SK Hynix, Hanmi, and Samsung Electro-Mechanics.
15 Why are South Korean defense exports booming? Korea Defense Industry · The Korea defense industry theme is long exposure to South Korean arms makers riding a record export boom led by Hanwha Aerospace, Hyundai Rotem, and KAI.
16 Why are Korean financials and holding companies re-rating now? Korea Financials & Holdings High Dividend · How Korea's Corporate Value-up Program, Commercial Act reform, and dividend tax relief are re-rating high-dividend banks, insurers, and holding companies.
17 How do the six pillars of Korea Manufacturing Core Alliance fit together? Korea Manufacturing Core Alliance · Korea Manufacturing Core Alliance is a friend-shoring theme covering Korean leaders in AI memory, batteries, ships, defense, the grid, and robotics.
18 Why is AI driving demand for optical networking? Optical Networking & Photonics · Optical networking (photonics) moves data with light and is a fast-growing AI-infrastructure theme led by Ciena, Coherent, and Lumentum.
19 Why now? The AI capex supercycle in equipment? Silicon Supply Chain · The silicon supply chain: the production stack behind every chip, from foundry and wafer-fab equipment to silicon wafers, substrates, and materials.
20 Why is energy storage growing so fast? Solid-State Batteries & Energy Storage · Solid-state batteries are the next-gen EV cell and ESS stores grid power, a Korean-led energy theme anchored by Samsung SDI and LG Energy Solution.
21 Why is the space economy growing? U.S. Space Tech · U.S. space tech is the commercial New Space theme: U.S.-listed upstream builders and downstream operators led by Rocket Lab, AST SpaceMobile, and Planet Labs.
22 Why are power, cooling, and equipment the bottleneck? US AI Data Center · The US AI data center concept covers the U.S.-listed companies behind AI's physical build-out: CoreWeave, Nebius, IREN, Oracle, Vertiv, Arista, and more.
23 Why now? What is the AI capex supercycle? US AI Semiconductor · The US AI semiconductor concept covers the U.S.-listed chipmakers behind the AI build-out: NVIDIA, Broadcom, Intel, AMD, Micron, TSMC's ADR, and more.
