Samsung Electronics' recent underperformance due to strike fears is overdone. The government has signaled emergency arbitration, making a full production shutdown unlikely. Past precedents show management-favorable resolutions. The valuation gap versus SK Hynix is excessive given Samsung's larger revenue base, and once the strike issue is resolved, the stock should rebound. Current weakness is a buying opportunity for long-term investors.

Samsung Electronics and SK hynix are core holdings given their combined 50% weight in KOSPI and their direct exposure to the AI memory supercycle. The recent labor strike is resolved, Goldman Sachs has raised earnings estimates sharply, and valuation may expand from PBR to PER as the market re-rates them. Not holding these stocks is a significant relative risk.

The AI revolution is creating unprecedented new demand and star stocks, similar to the 1995-99 internet cycle but backed by strong actual earnings. Market volatility during this level-up phase is natural and should be viewed as a buying opportunity rather than a reason to reduce exposure. The speaker believes this is a life opportunity in the Korean stock market, with the upward trend supported by robust corporate earnings, especially in semiconductors.

US big tech companies (hyperscalers) will ultimately outperform Korean stocks as AI moves from infrastructure buildout to monetization. Their cloud businesses are already showing high growth and margins (Google cloud +63%, Microsoft +40%, Amazon 38% margin). By 2028, their free cash flow is expected to surge even while investing heavily, leading to a re-rating. Investors should allocate part of their portfolio to US big tech, especially Google, Microsoft, and Amazon.

The AI revolution is currently in the infrastructure build phase, and the next phase will be dominated by killer services and large platforms, which are likely to be led by US companies. Therefore, even Korean-focused investors should allocate a portion (e.g., 10-20%) to US equities now to benefit from the upcoming wave, rather than trying to time entry later.

NVIDIA's upcoming earnings will be strong due to continued AI infrastructure spending, high product prices, and management's upward revision of potential TAM. The stock has recently broken out of a consolidation range and trades at a reasonable P/E of 24-26x, making a positive post-earnings reaction likely. Contrary to the pattern of past earnings selloffs, this time investor positioning is lighter, reducing the risk of a sell-the-news event.

Money is rotating from semiconductors into previously neglected software and big tech names after strong earnings reports from companies like Palantir. The performance gap is closing, making US software/big tech an attractive area.

The high USD/KRW exchange rate boosts semiconductor export earnings, and foreign selling is merely a mechanical rebalancing due to US tax laws, not a fundamental exodus from Korean equities.

The recently listed SpaceX stock benefits from an extreme supply-demand imbalance: only about 4-5% of shares were floated, while massive mandatory demand from space-themed ETFs, Nasdaq-100 inclusion in June, growth fund managers, and Tesla/Musk retail followers creates a near-term floor. Until the lock-up expiry in roughly three months, the supply squeeze makes a sharp short-term selloff very difficult, generating a positive momentum window for short-term traders.
