June 28 Market Report: Micron Edges Up, Tech Stocks Close Mixed

Major Tech Stocks Show Mixed Performance, Micron Closes Higher

On June 26, 2026, major technology companies' stock prices showed divergent trends in the stock market. An analysis of stock data for key tech firms listed primarily on U.S. exchanges revealed that Micron, a semiconductor-related stock, garnered investor attention with a slight increase. In contrast, Apple closed trading near the breakeven point, while NVIDIA and Google also recorded minor declines, indicating weakened upward momentum across the tech sector.

According to data, Micron Technology closed trading at 1,213.56 won, up 0.16% from the previous day. This can be interpreted as a move to continue a positive trend, aligning with recent expectations for a recovery in the semiconductor sector. Micron's market capitalization reached 1.37 trillion won, and while its EPS growth rate is not specified in the current figures, it serves as an indicator for evaluating the market's potential growth.

Conversely, NVIDIA, which competes for the top global market cap position, fell 0.02% to 195.74 won, with its market capitalization tallied at 4.74 trillion won. Apple closed down 0.06% at 275.15 won, recording a market capitalization of 4.04 trillion won. Alphabet (Google) stocks, GOOGL and GOOG, remained near the breakeven point, closing at 343.71 won (-0.00%) and 342.19 won (-0.01%) respectively. Analyses suggest that the weakness in these large tech stocks could have a somewhat negative impact on overall market investor sentiment.

The company with the highest market capitalization on this day was NVIDIA (4.74 trillion won), followed by Alphabet (4.19 trillion won) and Apple (4.04 trillion won). Their respective P/E ratios of 29.9, 26.2, and 33.4 indicate they maintained levels significantly higher than the market average, reflecting expectations for growth priced into their valuations. Notably, NVIDIA and Alphabet demonstrated very high EPS growth rates (6599.3% and 3419.4% respectively), suggesting that profit growth is supporting their stock prices. Apple also showed a high EPS growth rate of 2258.6%.

In contrast, some companies recorded sluggish growth rates. Tesla reported an EPS growth rate of -4709.0% with a very high P/E ratio of 344.1, indicating a high valuation relative to current earnings and suggesting potential for significant stock volatility depending on future performance improvements. Meta Platforms also recorded an EPS growth rate of -256.0%, but its P/E ratio was relatively lower at 19.7.

Of particular note is the prominent movement within the semiconductor equipment and related sectors. TSMC (2.26 trillion won, P/E 37.5, EPS growth 4430.2%), Broadcom (1.80 trillion won, P/E 62.9), ASML (0.71 trillion won, P/E 62.5), Applied Materials (0.53 trillion won, P/E 62.9), and Lam Research (0.50 trillion won, P/E 75.8) are expected to see continued demand growth alongside the AI industry's expansion, despite their high P/E ratios. The high P/E ratios for these companies are interpreted as reflecting the market's high expectations for future growth.

Tech Sector Trends and Market Impact

Recently, the technology sector has garnered considerable interest due to investments related to Artificial Intelligence (AI) and expectations for a recovery in the semiconductor industry. Particularly, the sharp rise in stock prices of AI chip-related companies like NVIDIA and AMD has been a major driver of market growth. However, the mixed performance of major large-cap tech stocks such as NVIDIA, Google, and Apple, as shown in the June 26 data, suggests the possibility of short-term profit-taking or the market entering a period of consolidation.

Indeed, the June 26, 2026, data for major tech stocks displayed mixed trends, indicating that market participants are adopting a cautious stance between the sustainability of AI-related stock rallies and valuation concerns. Domestic media reports, including those from Yonhap News, are analyzing that discussions around AI profitability are resurfacing, which could become a significant variable for the future stock movements of tech companies.

The volatility in the tech sector also impacts the broader stock market. The KOSPI market is also analyzing its direction amidst semiconductor-centric earnings momentum and global monetary policy fluctuations. As reported by Yonhap News, the stock market has reached a critical inflection point, and the ups and downs of large tech stocks are likely to influence overall market investor sentiment. The Vanguard S&P 500 ETF (VOO) and the SPDR S&P 500 ETF (SPY), tracking the S&P 500 index with market capitalizations of 1.70 trillion won and 0.78 trillion won respectively, show a stable overall market trend through their minor movements, while also suggesting a buffer role to prevent weakness in specific sectors from dragging down the entire market.

Meanwhile, concerns are being raised in the Korean stock market that leveraged ETFs on single stocks like Samsung Electronics and SK Hynix are amplifying domestic market volatility. As reported by various media outlets, including Yonhap News, such concentrated investment products can magnify market fluctuations depending on the stock price movements of the underlying companies, requiring investor caution.

Future Market Outlook and Investment Implications

Looking ahead, the tech stock market is expected to remain volatile depending on the pace of AI technological advancements, semiconductor demand outlook, and changes in the macroeconomic environment. While there are stocks like Micron showing positive figures, there are also stocks like Tesla exhibiting high valuations and sluggish profit growth. Therefore, it is crucial for investors to meticulously analyze individual companies' fundamentals and growth prospects.

The EPS growth rate data for major technology companies shows that NVIDIA, Google, Apple, Microsoft, Amazon, and TSMC, among others, continue to demonstrate strong profit growth. This suggests that the long-term investment appeal for companies providing key infrastructure and technologies for the AI era remains valid. However, cautious judgment is needed on whether these high growth rates are already fully reflected in stock prices or if they can be sustained going forward.

Valuation concerns must be considered for stocks with high P/E ratios. Companies like Broadcom, ASML, Lam Research, and Applied Materials, which record high P/E ratios, are expected to achieve future growth based on their technological prowess and market dominance. However, they could face risks of stock corrections if their growth pace slows more than anticipated or if profitability deteriorates due to intensified competition.

Regarding the domestic stock market, attention is needed on how market revitalization policies will impact it, as the KOSDAQ market approaches its 30th anniversary. According to Yonhap News reports, there is much interest in whether government policies can serve as an opportunity for the KOSDAQ market to rebound. Furthermore, investors are advised to recognize the risk of amplified volatility due to single-stock leveraged ETFs and manage risk through diversified investment strategies.

In conclusion, the stock market data for June 26, 2026, showed a trend of mixed performance in large tech stocks, with some individual stocks like Micron showing strength. The market is expected to set its direction in the future by comprehensively considering the sustained growth potential of the AI and semiconductor sectors, along with macroeconomic factors such as interest rate fluctuations and geopolitical risks. Investors would be wise to maintain a conservative approach, carefully assessing individual companies' earnings, growth potential, and valuation levels, and preparing for overall market volatility.
