AI memory shortage drives semiconductor upcycle.
Memory semiconductors are in a structural upcycle because AI data-center and robot demand are outstripping supply. Micron's IR meeting indicated NVIDIA Rubin/Blackwell demand extending through 2026, rising Broadcom TPU demand, only 20% capacity growth versus over 30% demand growth, and an inability to meet 50-55% of key customers' mid-term memory needs. DRAM average prices are expected to rise about 60% y/y in 2026, and new fab supply arrives only late. SanDisk also expects enterprise NAND prices to rise 100% in March, with buyers seeking 1-3 year supply guarantees and prepaying cash.
Defense and space stocks surge globally.
Geopolitical risk is rising globally, and defense stocks are surging not only in the US but across major markets. Korean defense and space names participated strongly, with Hanwha Systems up 27.5%, Hanwha Aerospace up 11.3%, and gains in Korea Aerospace Industries, LIG Nex1, and Hyundai Rotem. The speaker treats the group as a key market leadership theme.
Micron benefits from AI memory shortage.
Micron is a direct beneficiary of the AI memory shortage. Its investor meeting cited NVIDIA Rubin/Blackwell demand through 2026, rising Broadcom TPU demand, capacity expansion of only 20% versus demand growth of over 30%, and an inability to meet 50-55% of key customers' mid-term memory demand. DRAM average prices are expected to rise about 60% y/y in 2026, and new fab supply will not arrive until late, keeping the market undersupplied. Humanoid robots could add massive memory demand because each unit may need 128GB DRAM and 2TB NAND.
SanDisk gains from NAND price hikes.
SanDisk is benefiting from an AI storage shock that has turned the NAND market into a seller's market. Enterprise NAND prices are expected to rise 100% in March. Buyers asking for 1-3 year supply guarantees are being told to prepay in full cash. General NAND supply is structurally tightening as memory makers prioritize AI products, giving SanDisk strong pricing power.
KOSPI momentum remains upward, watch corrections.
KOSPI rose 6% in the first week of January and posted six consecutive up days. Foreigners sold due to FX weakness, but retail investors absorbed the selling, and leadership rotated from memory to autos, shipbuilding, defense, and nuclear power. The speaker says market sentiment is biased upward and participants should follow the rally while it runs, though a fast move could invite a correction; some see 4,500-4,600 in Q1.
Samsung, SK hynix lead Korean memory rally.
Samsung Electronics and SK hynix are the market leaders and retail investors are absorbing heavy foreign selling driven by FX instability. Expectations remain strong, and the two stocks led the KOSPI's first-week rally, with Samsung up 8.1% and SK hynix up 9.9% for the week. However, the speaker warns that memory-cycle peaks are usually discounted 6-12 months ahead, so the timing of the shortage peak matters for further upside.
Hyundai Motor Group benefits from physical AI.
Hyundai Motor Group was the biggest CES beneficiary, with the market focusing on physical AI, robotics, and autonomous driving. The group had been held back by tariff concerns and worries that 2025 would be a peak, but the speaker argues the stocks were undervalued and the physical AI narrative should continue to support Hyundai Motor, Kia, Hyundai Mobis, and Hyundai Glovis.
Korean shipbuilders gain on full orderbooks.
Korean shipbuilders surged as orderbooks are full and dock capacity is tight. Samsung Heavy Industries, HD Korea Shipbuilding, and HD Hyundai Heavy Industries saw strong gains, and the sector is benefiting from tight global capacity and US interest in Korean shipbuilding modernization.
AI data centers need on-site power.
AI data centers need on-site power generation because grid operators say they cannot handle the load. The speaker points to fuel cells, gas turbines, and SMRs as required solutions, and in Korea, the government is discussing an energy transition that could increase the nuclear share. Doosan Enerbility is the named nuclear equipment play and saw a large weekly gain.
JPM healthcare conference may lift KOSDAQ biotech.
The JPMorgan Healthcare Conference is a key catalyst this week. If large pharma or biotech announcements emerge, the speaker expects momentum could return to KOSDAQ biotech and help the broader KOSDAQ, which has lagged due to prior weakness in bio, robots, cosmetics, and entertainment.
Hanwha Ocean expands US shipyard capacity.
Hanwha Ocean's Philadelphia shipyard has no room for more orders, so it is pursuing nearby dock acquisitions and plans to bring Korean shipyard robots and modern manufacturing to the US. This creates potential for additional order and M&A headlines that could be positive for the stock.
Optical communications grows on AI infrastructure.
Goldman Sachs expects the global optical communications market to grow about 34% annually through 2028 on AI server infrastructure demand. The speaker notes the theme has already been reflected in stock prices, but it remains a developing AI infrastructure area to monitor.
Policy inflows support Korean equities.
The Korean government is introducing tax benefits to encourage long-term domestic equity investment, including a National Growth ISA, a productive finance ISA, a youth ISA, and an annual deduction for KOSDAQ venture funds. It is also pushing 24-hour FX trading, simultaneous settlement, and broader foreign individual access to Korean stocks, which supports MSCI developed-market inclusion. The speaker sees these as multiple routes for money to flow into the domestic stock market.
