■ Concentration in Samsung-hynix Deepens KOSPI Volatility: This month, the average daily purchase amount of Samsung Electronics (005930.KS) and SK hynix (000660.KS) accounted for 45.6% of the KOSPI, more than tripling from a year earlier (14.7%). With the combined market capitalization of the two stocks reaching 54.6% of the entire KOSPI, analysts say their sharp swings inevitably amplify index volatility.
■ Intel Emerges as Key Beneficiary of U.S. Semiconductor Revival: Intel’s stock has soared 440% in 10 months after striking consecutive partnerships with five big tech companies including Apple, Google, and Nvidia. Analysts say the possibility of a turnaround in its foundry division is growing as surging demand for inference AI CPUs combines with full-fledged support from the Trump administration.
■ ETFs Establish Themselves as New Driver of Stock Trading: ETFs accounted for 30.4% of domestic stock trading value this year, the highest share on record. While funds concentrate on semiconductor and AI themes, retail investors are shifting their weight toward index-type and mixed products rather than leverage, burdened by high price levels.
[News of Interest to Stock Investors]
1. Half of KOSPI Buying Is Samsung-hynix… Concentration Triples in a Year
– Key Summary: This month, the average daily purchase amount of Samsung Electronics and SK hynix reached 22.0997 trillion won, accounting for 45.6% of the entire KOSPI. The share, which was just 14.7% in May last year, jumped 3.03-fold in one year, and the concentration accelerated further after the launch of single-stock leverage products last month. On this day, SK hynix surged to as high as 2.891 million won during trading, surpassing 2,000 trillion won in market capitalization, but Samsung Electronics closed down 2.34%, leaving the KOSPI to finish 0.13% lower at 9,052.42. With volatility intensifying to the point where the intraday high-low gap reached 553.87 points, concerns are growing that a supply-and-demand structure concentrated in a few large-cap stocks heightens overall market risk.
2. With Five Big Tech Partners Including Nvidia… Intel’s Stock Soars 440% in 10 Months
– Key Summary: After President Trump officially announced a semiconductor cooperation agreement between Apple and Intel, Intel’s stock jumped 11% in a day to close at $133.99. Since the U.S. government acquired a 10% stake last August, Intel has secured five key big tech firms as partners, including Google (commissioned to produce more than 3 million TPUs), Nvidia (GPU packaging technology cooperation), Tesla, and SpaceX. While profitability remains incomplete, with the foundry division posting a $2.4 billion loss in the first quarter of this year, Intel has moved swiftly to recruit former SK hynix executive Lee Seok-hee as foundry vice president to accelerate yield improvements. A Bernstein analyst explained, “The supply shortage environment is driving customers who would normally have hesitated to turn to Intel.”
3. ETF Trading Share Tops 30%… 34 Trillion Won Traded Daily
– Key Summary: Of the total domestic stock trading value this year (5,513 trillion won), ETFs accounted for 2,407 trillion won, exceeding 30% for the first time. The average daily ETF trading value more than doubled from 14.4099 trillion won in January to 34.347 trillion won in June, setting a new record high. The top trading ranks were led by KODEX Leverage (243 trillion won) and KODEX 200 (218 trillion won), followed by three semiconductor ETFs lined up side by side. While semiconductor and IT ETFs maintain a positive disparity rate relative to net asset value, KOSDAQ and high-dividend ETFs are in a negative disparity state, in an analysis confirming retail investors’ preference for the semiconductor sector in figures.
4. Burdened by High Prices… Retail Investors Sell Leverage, Buy Index Products
– Key Summary: After the KOSPI broke through the 9,000 level, retail investors realized profits in KODEX Leverage (-1.2005 trillion won) and semiconductor leverage ETFs, shifting funds to KODEX 200 (+681.3 billion won) and ETFs tracking the U.S. S&P 500 and Nasdaq 100. A notable trend is that despite the return on the SK hynix single-stock leverage ETF exceeding 60% in a week, investors chose portfolio rebalancing rather than chasing the rally. Credit loan balances declined slightly from 38.0226 trillion won at the end of last month to 37.9796 trillion won on the 18th, showing none of the surge in “debt-fueled investing” seen in past bull markets. An asset management official said, “The trend of reducing leverage exposure and increasing index-type and mixed products is not abandoning the bull market, but a move to participate while controlling risk.”
