The correlation between the Nasdaq 100 futures and the Korean day session trend is getting higher and higher. Yesterday, when Korea was closed for the holiday, the volatility in the overnight session was relatively moderate. Today, with the Korean stocks trading normally, the volatility in Nasdaq 100 futures jumped directly—both rose and fell almost in lockstep on an intraday basis.
At its core, KOSPI in Korea is now nearly a semiconductor index. Samsung and SK Hynix have extremely high weightings. As a key global supplier of HBM and storage, they directly mirror global AI hardware demand expectations.
A timing mismatch creates a feedback loop: during the Asian session, Korea moves first. Global capital then treats the rise and fall of Korean stocks—specifically the semiconductor/storage segment—as a leading sentiment indicator for the AI sector, and feeds that straight into the Nasdaq 100 futures order book. This is no longer the one-way transmission from U.S. equities to Korea as in the past; it has turned into two-way interaction, influencing each other.
It also means that, going forward, when looking at global technology sentiment, the signal weight of the Korean order book will be further enhanced. But it’s important to distinguish: this is a resonance between sentiment and expectations—not that Korean stocks can determine U.S. stocks. In extreme cases, the two can even diverge.
