Ideas
US growth benefits broaden to small caps.
US economic growth forecasts are being revised up, and the benefits are broadening from mega-cap tech toward small and mid-sized companies; the Russell 2000 has started outperforming the S&P 500 and Nasdaq, supporting a long small-cap position.
Power rate controls pressure generator margins.
AI data-center power demand has pushed wholesale electricity prices higher, making power bills political. PJM governors are moving to stabilize rates and shift costs to large data centers; if rates are capped or long-term fixed contracts increase, generator margins may shrink. Constellation Energy and Vistra fell sharply.
Grid equipment demand is unavoidable.
Even if electricity rates are controlled, grid expansion and new power equipment investment are unavoidable because AI data centers keep increasing power demand; GE Vernova and Eaton rose on this view.
AI power demand lifts nuclear SMRs.
Nuclear SMR companies also strengthened as AI data centers increase electricity demand, making nuclear power an alternative energy source; Oklo and NuScale Power rose.
Neoclouds benefit from data-center power strain.
PJM power-cost issues create electricity cost and capex pressure for hyperscalers and large data centers, while distributed small and mid-sized data centers, or neoclouds, benefit; CoreWeave, Cipher Mining, and IREN rose sharply.
AI profits favor hardware over software.
AI industry profit is still concentrated in AI hardware, while AI software stocks remain weak; the speaker believes the AI trade should stay weighted toward hardware rather than software.

Tesla owns multiple AI autonomy verticals.
Korean retail flows concentrated in Tesla because CES 2026 highlighted self-driving, FSD, robotaxis, humanoid robots, and AI platforms; Tesla owns multiple of these AI and autonomy verticals.
Micron benefits from AI memory upcycle.
Insider buying news drove Micron shares sharply higher and lifted memory names; AI server, HBM, and DDR5 earnings momentum is improving, and the speaker sees this as positive for the Korean market. Later TSMC’s strong capex outlook reinforces memory demand.
S&P 500 remains supported by US growth.
US economic growth forecasts keep rising, leading investors to believe the S&P 500 will not break; US retail buying is concentrated in VOO.
Ultra-short Treasuries favored as yields stay high.
Long-term Treasury yields are rising and overall rate levels are high, so investors prefer ultra-short US Treasuries such as SGOV for attractive yield with low duration; a similar Korean ultra-short bond ETF exists.
Walmart joins Nasdaq 100 with momentum.
Walmart’s share price has been strong and it is being added to the Nasdaq 100 on January 20, which can bring passive inflows; the speaker says to watch Walmart.
Trump Media Bitcoin ETF signals crypto support.
Trump Media’s Bitcoin ETF registration appears in SEC documents and is likely to list soon; the speaker sees this as a positive signal for Bitcoin and related crypto.
Passive flows favor expensive large caps.
Passive ETF flows are market-cap weighted, so large and expensive winners keep getting larger index weights while cheap laggards get smaller. The speaker advises individual investors to buy expensive large companies more aggressively and avoid cheap companies.

Dividend tax break favors Korean holdings/financials.
Korea’s dividend income separate taxation is being applied from this year. A Mirae Securities report identifies holding companies and financial companies likely to qualify as superior or effort types; ETF issuers launching dividend ETFs are likely to include these stocks, creating demand. Investors taking profits in semiconductor, AI hardware, or humanoid names can rotate into these beneficiaries.
TSMC confirms strong AI capex cycle.
TSMC’s Q4 beat with a 62.3% margin, 2026 revenue growth guidance above 30% in USD, AI accelerator revenue CAGR in the mid-to-high 50% range, and 2026 capex of $56 billion. The speaker says this confirms AI demand, continued AI chip supply shortage, and explosive capex, making TSMC an AI proxy with record results and investment.
TSMC capex favors AI chip supply chain.
TSMC’s aggressive 2026 capex and persistent AI chip supply shortage imply record investment across the AI semiconductor supply chain; the speaker says market participants should look to buy AI front-end equipment, materials, and packaging companies.
Korea momentum remains strong.
KOSPI rose 5.5% in a week with an 11-session winning streak, led by Samsung Electronics and SK hynix and broadening out; foreign spot buying returned, futures are rich, and arbitrage buying signals strong upward momentum. The speaker says this week looks not bad and prefers momentum-clear Korea over a mixed US market.
Korean memory leaders drive KOSPI.
The KOSPI rally started with SK hynix and spread; Samsung Electronics and SK hynix were the most prominent leaders. The speaker notes that buying KOSPI 200 is similar to buying them, and Micron and TSMC news supports the memory cycle.
Hyundai leads Korean humanoid robot adoption.
Humanoid robots are moving into real industrial sites; large manufacturers such as Hyundai Motor can deploy them immediately and collect learning data, making the robots smarter. Retail flows are buying the TIGER Korea Humanoid Robot Industry ETF and Hyundai Motor group ETFs on this theme.
Foreign options shift to volatility buying.
Foreign investors appear to have given up selling calls and are buying out-of-the-money calls, creating a V-shaped volatility-buy or straddle position with break-even around 740 and profits below 640 or above 800. This is a notable volatility-buying setup.
