Summary

Mirae Asset ETF Consulting Director Choi Chang-gyu reviews the August 14 US market drop, the AI memory/storage rotation, Nvidia's $500B AI infrastructure finance platform, CoreWeave and Supermicro earnings, SanDisk's HBF roadmap, and Korean export and equity breadth. He identifies ongoing AI differentiation and improving Korean rally quality, with key catalysts at FOMC minutes and Samsung Electronics' Tech Tour. Derivatives positioning suggests foreigners are positioned for lower volatility and mild upside.

  • August 14 US equities fell on weak retail sales and rising long-term yields, but memory/storage names and AMD outperformed.
  • Retail flows showed profit-taking in 3x semiconductor ETFs and rotation into memory, cloud platforms, and power/cooling infrastructure.
  • Nvidia's $500B AI infrastructure financing platform is seen as a short-term catalyst for AI value chain investment, with residual value and circular financing risks.
  • CoreWeave and Supermicro results confirmed AI compute demand and real server orders, while SanDisk's HBF roadmap added a new AI memory layer.
  • Korean July exports and the KOSPI rally broadened beyond Samsung Electronics and SK Hynix into autos, shipbuilding, and industrial sectors.
  • Hyundai Motor's oversold rebound is testing its 200-day average and is highlighted as a Hyundai Group and physical AI ETF consideration.
  • FOMC minutes and Samsung Electronics' Tech Tour are the key catalysts, while foreign options positioning implies low volatility and mild upside.

Memory/storage semiconductors outperform within AI.
On August 14, while US equities were pressured by soft consumption and higher long-term rates, memory/storage semiconductor names outperformed: SanDisk +7.39%, Seagate +5.65%, Western Digital +4.41%, Micron +2.3%. The speaker says the AI semiconductor market has entered a phase where names confirming demand and beating expectations are being rewarded, with buying concentrated in memory/storage.

AI flows rotate beyond GPUs to infrastructure.
Korean retail investors sold 3x semiconductor leveraged ETFs and former AI leaders Nvidia, Broadcom, and Microsoft, while continuing AI exposure by rotating into HBM/memory names such as SK Hynix ADR and Micron, cloud AI service platforms Amazon and Alphabet, and power/cooling infrastructure Bloom Energy and Vertiv. This shows AI investment expanding from GPUs into memory, cloud, power, and data center infrastructure.

Nvidia financing fuels AI infrastructure value chain.
Nvidia's $500B+ AI infrastructure financing platform with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, and KKR uses a residual value guarantee of up to 25% to attract Wall Street long-term capital and raise customer GPU purchasing power. The speaker views this as a short-term positive catalyst for AI semiconductors, power, and data center infrastructure, while flagging residual value and circular financing risks.

CoreWeave/Supermicro confirm real AI orders.
CoreWeave's Q2 revenue rose 112% year over year with adjusted operating income above guidance and a $104B order backlog, confirming AI compute demand. Supermicro posted FY26 revenue growth of 78% and record Q4 new orders exceeding $60B with FY27 revenue guidance of $65-72B, showing orders are converting into actual server deployments. This supports the view that the AI cycle has shifted from capex competition to real orders and revenue, though CoreWeave's leverage and Supermicro's timing/margin volatility are risks.

Korean export recovery broadens beyond semiconductors.
July Korean exports rose 62.8% year over year to $98.89B, a 14th consecutive record month, led by semiconductor exports up 178.8%. The speaker emphasizes the recovery is not semiconductor-only: autos rose 7%, ships rose 79.9%, and 19 of 20 major export items increased, so domestic equity leadership can rotate beyond semiconductors into autos, shipbuilding, and industrial/parts sectors.

Samsung Tech Tour may catalyze Korean semis.
Samsung Electronics' Tech Tour beginning August 20 is seen as a key catalyst. The market will watch HBM4 competitiveness, next-generation DRAM, NAND strategy, foundry yields, and AI customer progress. If these points land positively, they could improve sentiment for Samsung Electronics and Korean semiconductor materials/components/equipment names.

Korean rally broadens beyond mega-cap semis.
KOSPI rebounded sharply and Samsung Electronics and SK Hynix returned as leaders, but unlike past semiconductor-led rallies, the move did not concentrate solely in those two names. KOSDAQ also rose more than 8%, which the speaker interprets as improving rally quality and a healthier broader Korean market advance.

Oversold Hyundai Motor tests 200-day line.
Hyundai Motor rose more than 8% after having fallen from near 780,000 won to the mid-300,000s, driven by an oversold rebound. The stock is now testing its 200-day moving average, a key technical line, and the speaker suggests considering Hyundai Motor Group-related and physical AI-related ETFs this week while monitoring whether it breaks the 200-day resistance.

Foreign options bet low volatility upside.
Foreigners are building KOSPI 200 option positions that are short volatility and mildly upward-biased. The payoff is centered around a rise toward the 1,200 area, with downside puts below 850 as tail protection. This suggests the foreign options market is positioned for declining volatility and a moderate upward drift rather than a large breakout.
