1. This Time 11 Shares Send hynix to Limit-Low… Is the Pre-Market Fine As Is?

- Key Summary: SK hynix (000660), with a market capitalization exceeding 1,100 trillion won, recorded a limit-low during the session on just 11 shares traded in the pre-market. According to the financial investment industry on the 6th, SK hynix formed an opening price of 1.168 million won right after the alternative trading system's pre-market opened, down 29.97% from the previous session's closing price of 1.668 million won. This came just seven trading days after it recorded a limit-low on the 28th of last month on a single-share execution, and the background is cited as the continuous auction trading method used when liquidity is insufficient right after the opening. Nextrade plans to introduce a static volatility interruption device (VI, a system that switches to single-price trading when an order price diverges significantly from the reference price) on the 14th of next month.

2. Upper or Lower Limit on Even One Share If the Price Matches… "Volatility Interruption Devices Needed Urgently"

- Key Summary: The way the pre-market forms opening prices is being cited as a factor raising investor caution in the domestic market. On the 5th, the day before the limit-low incident, Samsung Electro-Mechanics (009150), the fifth-largest by market cap on the KOSPI, and Alteogen (196170), the largest by market cap on the KOSDAQ, each formed opening prices at their upper limit on a single share traded. Since Nextrade's launch in March last year, cases of opening prices being distorted by small trades have continued, but the formation method has not changed. Meanwhile, the KOSPI 200 Volatility Index (VKOSPI) fell to 77.17 that day from 96.9 on June 29, but remains far above its historical average in the 20-point range.

3. Won Strengthens Even as Stocks Plunge 4.6%… Exchange Rate Drops Sharply to 1,410-Won Range

- Key Summary: The won-dollar exchange rate slipped to 1,414.5 won during the session on the 6th, marking the lowest level in about 10 months since October 2 last year. The closing rate finished at 1,423.8 won, down 0.7 won from the previous session. The won's strength was supported by exporters' selling of dollars, dollar inflows related to SK hynix's American Depositary Receipt (ADR) listing, stable international oil prices, and a stronger yen. An unusual trend emerged in which the exchange rate fell even as the KOSPI plunged 4.58% that day and foreigners net-sold 3.3273 trillion won.

4. Shaken Hyundai Motor Group Stocks… Market Cap Rankings and ETFs Also Retreat

- Key Summary: The share prices of Hyundai Motor Group's core affiliates remain unable to escape a joint downturn. Hyundai Motor closed at 400,000 won on the 6th, down 1.11%, a 46.6% drop from 750,000 won on June 1, and its KOSPI market capitalization ranking slid from fourth to fifth. Hyundai Mobis fell 33.2% over the same period, retreating in market cap ranking from 10th to 16th. In addition, group-stock exchange-traded funds (ETFs) posted uniformly weak returns, with TIGER Hyundai Motor Group Plus falling 31.3% and SOL Automobile TOP3 Plus falling 39%.

5. Capital Capacity Grows in the Second Half… Struggling to Find "Productive Finance" Investment Targets

- Key Summary: Observations are emerging that domestic financial holding companies' capacity for corporate lending will grow in the second half due to the sharp drop in the exchange rate and eased capital regulations. Hana Securities forecast that if the won-dollar exchange rate stays around 1,430 won through the end of the third quarter, major commercial banks will generate 70 billion to 100 billion won in foreign currency translation gains, and their common equity Tier 1 (CET1) ratios will rise 25 to 30 basis points. If a plan to shorten the operational risk reflection period from 10 years to three years is applied, CET1 could rise up to an additional 26 basis points. However, as large-scale investments in artificial intelligence, semiconductors, and bio are executed preemptively, concerns are deepening over finding new investment targets.

6. Eleven PEF Regulation Bills in One Year… Only Foreign Firms Smile

- Key Summary: Concerns have been raised that private equity fund (PEF) regulation bills successively proposed in the National Assembly apply only to domestic managers, creating reverse discrimination. A total of 11 amendments to improve the institutional-only PEF system have been proposed since July 2025, including regulations on borrowing limits, strengthened reporting obligations to financial authorities, and disclosure of managers' compensation. In contrast, the latest Asia buyout funds of the seven top global PEFs active in Korea — including Blackstone, KKR, and Carlyle — reach 100 trillion won, but they raise funds overseas and sidestep domestic legal regulations. As a result, concerns are emerging that the position of domestic PEFs will shrink and that the local mergers and acquisitions (M&A) market could be handed over to foreign capital.
