The Dawn of the AI Supercycle
Semiconductor Hegemony, Value Reassessment, and an In-depth Analysis of the New Cycle Driven by AI
Executive Summary
This report provides an in-depth analysis of the structural changes in the semiconductor industry triggered by innovations in artificial intelligence (AI). We quantitatively assess the competitive landscape and fundamentals of SK Hynix and Samsung Electronics, focusing on the demand expansion centered around High Bandwidth Memory (HBM). The report examines the impact of geopolitical risks, such as the Middle East conflict, on the industry through various pathways and illuminates the intrinsic value of these companies using Discounted Cash Flow (DCF) modeling. By simulating three scenarios—optimistic, neutral, and pessimistic—and considering the perspectives of renowned investors, we aim to offer insights into the new cycle and future prospects of the AI-era semiconductor industry.
This document is an AI analysis example, and investment decisions are solely the responsibility of the individual.

1. Macro Environment Analysis: The Formation of a New Order
1.1 The AI Revolution and Semiconductor Demand
The nature of demand is being redefined by the massive paradigm shift of AI, moving away from past cycles centered on PCs and mobile devices. This structural change presents a new growth equation for the semiconductor market.

1.2 Geopolitical Risk Spillover Effects
Geopolitical risks, such as Middle East conflicts, are more likely to act as a variable that worsens cost structures rather than demand itself. The spillover channels are as follows:
2. In-depth Analysis of Key Companies: The Two Giants of Memory
SK Hynix
HBM Market Preemption and Sustainability
- Market Dominance: Achieved ~70% HBM market share in Q1 2025.
- Technological Leadership: Proactively supplied HBM3/3E to NVIDIA.
- Customer Trust: Built a "relational moat," securing an advantage in next-gen products.
- Performance Improvement: High HBM profitability led to becoming the global No. 1 in DRAM sales.
Samsung Electronics
From Follower to Leader: AI Transformation Strategy
- Potential: Capable of providing "turnkey" solutions by internalizing memory, foundry, and packaging tech.
- Catch-up Strategy: Concentrating R&D on HBM3E 12-Hi and HBM4 development.
- Risk: Delayed HBM market entry is a short-term valuation discount factor.
- Opportunity: Entering NVIDIA's supply chain could resolve major uncertainties and lead to a stock re-rating.

4. Future Outlook & Investment Strategy Simulation
4.1 Second Half 2025 Scenario Analysis
Optimistic Scenario
- AI demand exceeds expectations.
- Samsung begins supplying HBM3E within the year.
- Middle East risks stabilize, interest rates fall.
Neutral Scenario
- AI demand meets expectations.
- Samsung's HBM supply delayed to early 2026.
- Middle East tensions persist, rates hold steady.
Pessimistic Scenario
- AI investment slows due to recession.
- Samsung's HBM certification fails.
- Middle East conflict expands, further rate hikes.
4.2 How Would the Masters of Investment View This?
| Investor | Core Philosophy | Virtual Portfolio Simulation |
|---|---|---|
| Warren Buffett | Value Investing, Economic Moat | Considers Samsung, discounted due to uncertainty, from a long-term holding perspective. |
| Peter Lynch | Growth Investing, Ten-Baggers | Includes HBM leader SK Hynix and key materials/equipment companies in the portfolio. |
| Ray Dalio | Macro, Asset Allocation | Combines tech ETFs, commodities, and bonds rather than focusing on individual stocks. |
