AI is reshaping the economics of memory — but it has not necessarily eliminated the semiconductor cycle.
This series examines how HBM, AI infrastructure and changing demand patterns are reshaping South Korea’s strategic position in the global semiconductor industry — and why traditional valuation frameworks may no longer tell the whole story.
Series Introduction
AI Is Reshaping the Memory Cycle: How Should Investors Value Korean Semiconductor Stocks?
An introduction to the central investment question behind the series: whether AI has structurally changed the memory industry and how investors should value Samsung Electronics, SK Hynix and Korea’s semiconductor ecosystem as a result.
Part I
AI Is Reshaping the Memory Cycle: Why South Korea Matters
Why South Korea occupies a uniquely important position in the AI memory supply chain — and why the global shift toward HBM makes the country increasingly difficult for technology investors to ignore.
Part II
The Memory Cycle Is Not Dead: Why P/E and P/B Send Opposite Signals
AI may be changing the structure of memory demand, but cyclicality has not disappeared. This chapter examines why conventional P/E and P/B signals can point investors in opposite directions at different stages of the memory cycle.
Part III
AI, China and the New Korean Semiconductor Order
The semiconductor industry is no longer driven by economics alone. Technology controls, China’s memory ambitions and supply-chain realignment are changing the competitive environment facing Korean semiconductor companies.
Part IV
Samsung vs. SK Hynix: Has AI Created a New Valuation Equilibrium?
Samsung Electronics and SK Hynix entered the AI era from very different competitive positions. The final chapter asks whether HBM and AI have created a lasting change in the relative valuation of Korea’s two memory giants.
