Semiconductor leaders remain unchanged; Samsung Electronics and SK Hynix are still the core holdings and should be kept through volatility. The rally confirms that the previous winners (semiconductors) will continue to lead, so investors should hold or buy into dips in these stocks.

The KOSPI and KOSDAQ are expected to rise gradually toward their 20-day moving averages (KOSPI 2,800 area, KOSDAQ 900) over the next one to two weeks, as CPI and other macro events are unlikely to derail the market. Investors should hold and not rush to sell.

Hyundai Heavy Industries (HD Hyundai Heavy Industries) is attractive because it is linked to AI data center demand for engines, showed relative resilience during the recent selloff, and rebounded quickly. It is a candidate for new buying if the market continues to recover.

As semiconductor capex expands to build new fabs, front-end process equipment orders will be the first to surge. Companies such as PSK, Tes, Eugene Tech, and Wonik IPS possess dominant market shares often above 50% and exceptionally high operating margins (~50%), ensuring they benefit early and sustainably from the capex cycle.

Nuclear, shipbuilding, and transformer stocks that maintain their 20-day moving averages are the best dip-buying candidates. Doosan Enerbility (nuclear), Hyundai Electric (transformers), and HD Hyundai Heavy Industries (shipbuilding) have strong trends and were sold off today purely due to rotational flows into semiconductors. This pullback is a buy opportunity as underlying themes remain intact.

When the market stabilizes after a panic selloff, robot stocks are the sector where fresh supply/demand inflows concentrate. They have led gains for two consecutive days, with names like SPG, Rainbow Robotics, and Robotis consistently appearing at the top of the gainers list. The expectation is that robot stocks will continue to attract buying as the broad market rebounds, making them the preferred recovery play in KOSDAQ.

Hanwha Ocean and HD Hyundai Electric announced strong orders, but their stock prices were dragged down by the broader market crash. They are prime candidates for a quick rebound once the market stabilizes.

GS Construction is up on a day when the overall market is weak, buoyed by GS Group's massive data center investment and a large redevelopment pipeline. The company also has historical know-how in data center leasing, providing an additional thematic edge. The stock appears to have price merit after recent underperformance.

Hyundai Motor and Kia are poised to rally when global automotive heavyweights like BMW, Mercedes-Benz, and Toyota find a bottom or stop falling. The Korean duo has shown relative strength by holding up far better than global peers, and Korean funds will eventually rotate back into them after the current extreme concentration in Samsung Electronics and SK hynix fades.

Samsung Electro-Mechanics (009150.KS) has corrected sharply but is unlikely to collapse in a single candle. A bounce is expected around the 150,000 won level, making it a tactical long opportunity for a short-term rebound.

Large financial holding companies like KB Financial and Shinhan Financial have held up better than pure securities firms, benefiting from rising trading volumes (over 100 trillion won in May), potential interest rate increases widening net interest margins, and won stabilization. Their charts look resilient and they could lead if the market recovers.

Korean Air stands to benefit from stabilizing oil prices and a strengthening Korean won, which reduces dollar-denominated debt burdens. Combined with receding pandemic-era uncertainty, the stock can recover toward pre-COVID price levels in a multi-year re-rating.
