Market Closing Status

Key Issues: The domestic stock market is expected to maintain its upward momentum this week. Despite Iran mentioning the possibility of re-blocking the Strait of Hormuz, the dialogue between the U.S. and Iran continues, and the market is now focused on the earnings report from Micron, which acts as a bellwether for the memory semiconductor industry.

Market Characteristics: The domestic market is closely watching Micron's earnings, as it will determine whether the rally for Samsung Electronics and SK Hynix continues and if the KOSPI can hit the 9,000-point mark.
Today's Notable Stocks and Key Issues
Samsung Electronics and SK Hynix keep rising Investors in the top 1% of recent 1-month returns are heavily buying Samsung Electronics and SK Hynix, driving the market. Both stocks are buoyed by the AI frenzy and the semiconductor supercycle, leading to a series of upward revisions in target prices.
Shinhan Financial Group target price hike Securities firms are raising their target prices for Shinhan Financial Group, with some reaching as high as 140,000 won. Its "Value-up 2.0" strategy, linked to ROE and growth rates, is drawing attention, along with its strategy to strengthen non-banking sectors through its integrated "Super SOL" app.
Public offering subscriptions in the spotlight In the last week of June, the domestic stock market will see general investor subscriptions for three companies aiming to list on the KOSDAQ: Korea No. 16 SPAC, MadUp, and Lemon Healthcare.
AI-Driven Investment Ideas
Focus on the semiconductor sector In the first half of the year, the domestic market was led by large-cap tech stocks, including Samsung Electronics and SK Hynix, amid the AI frenzy and expectations of a semiconductor supercycle. Micron's earnings are expected to show improved supply and demand for global memory chips, which could drive further gains for domestic semiconductor stocks.
Potential for earnings improvement in brokerage stocks The brokerage sector is highly likely to see earnings improvements, supported by increased trading volume, the expansion of the ETF market, higher customer deposits, and a rise in retail investor influx. Diversified investment strategies in leading brokerage stocks are worth considering.
KOSPI performance in the first half, deepening semiconductor concentration Despite the heavy reliance on semiconductors, the KOSPI is performing well, slightly outpacing the KOSDAQ in terms of 3-year returns. However, the importance of diversification is being emphasized, as the concentrated investment strategy that yielded high returns by picking specific stocks favored by securities firms is seeing a reversal in the recent 1-year bull market.
Investment Cautions and Macro Context
Geopolitical risks in the Strait of Hormuz While Iran has mentioned the possibility of re-blocking the Strait of Hormuz, the ongoing dialogue between the U.S. and Iran suggests that immediate risks remain limited. However, it is necessary to be cautious about oil price volatility resulting from changes in the Middle East situation.
Interest rate uncertainty due to Fed Chair transition With the debut of U.S. Federal Reserve Chair Kevin Warsh approaching, future U.S. interest rate policy is expected to be a major market variable. This could also impact the domestic interest rate market and exchange rates.
Warning signs of market overheating As the KOSPI nears the 9,000-point mark, volatility is increasing, triggering warnings of an overheated market. It is necessary to keep an eye on market leverage levels, such as the 180 trillion won in Q1 loans from brokerage firms.
