Korean stock market crashes and circuit breakers in a single day, but Huang Renxun went to Seoul to frantically shop? Take you through the real logic behind the semiconductor crash! Today, the South Korean stock market experienced its worst day of the year, with KOSPI plummeting nearly 9% during trading, triggering circuit breakers, and Samsung and SK Hynix leading the way in the bloodbath. The whole network is exclaiming: Has the AI cycle really peaked? But an extremely magical contrast emerged: just this weekend when Nvidia CEO Huang Renxun fled the secondary market, he made a high-profile appearance in Seoul, not only meeting with SK Group Chairman Choi Tae won, but also directly making a new round of multi-year cooperation deals. On one hand, financial funds are crazily smashing the market, while on the other hand, the "chain owners" of the industrial chain are crazily locking in orders. Who is lying about the market and industry? Disassemble the following three core logics to help you understand the truth behind this sharp decline: 1. The South Korean stock market is no longer a national index, but a giant 'AI memory ETF' The trigger for this sharp decline was actually the collective correction of the semiconductor sector in the US stock market last Friday. In the past year, the driving force behind the surge in South Korean stocks was not the local economy, but the demand for HBM memory and the expansion of Nvidia's industrial chain. When global hot money wants to bet on AI infrastructure, Korean stocks are the most convenient entry point for funds; And once Wall Street starts reducing its AI positions and deleveraging at high levels, the highly liquid Korean stock naturally becomes the number one ATM. The tragic decline is essentially a concentrated clearing of crowded trading, rather than the destruction of industrial fundamentals. 2. Huang Renxun's long-term orders completely undermine the 'demand collapse theory' The capital market is voting with its feet, but the signals given by the industry chain are completely opposite. The core purpose of Huang Renxun's flight to South Korea this time is to finalize the expansion and cooperation of next-generation AI data center memory with SK Hynix and Samsung. The underlying business logic is extremely simple: if Nvidia's internal data model shows that the peak of AI infrastructure has passed, Lao Huang would never have gone to South Korea to sign a long-term contract at this point in time. At least from the top of the industry, there is currently no evidence of a sudden disappearance of AI demand. 3. AI bull market officially enters the cruel second half of 'profit reassessment' The past year has been a brainless stage of 'valuation extraction', as long as the business is related to AI, the entire sector has been thriving. But now, the market has entered the cruelest second stage: accounting. From the recent financial report of Broadcom to today's stock market crash in South Korea, funds are starting to scrutinize with a magnifying glass - the demand for AI is indeed still on the rise, but who exactly has these profits gone into their pockets? SK Hynix reaps absolute dividends from HBM, Samsung bets on advanced packaging, Micron eats server memory upgrades. The market is no longer willing to blindly premium the entire track, but is beginning to force companies to cash in profits on their reports one by one. Final deduction: What determines the nature of this Korean stock circuit breaker is not today's panic, but the capital expenditure data of North American cloud giants (CSP) and the real order rhythm of Nvidia in the future. If these hardcore data remain strong, then today's sharp decline is a perfect "high-level deleveraging wash"; If the data does indeed begin to weaken, that is the true signal of peaking. But for now, long-term contracts signed by industry giants with real money are far more trustworthy than panic selling like birds in the secondary market.
