July 1 Market Report: US Stocks Close Mixed Amid AI, Semiconductor Tailwinds

US Stocks Close Mixed Amid AI and Semiconductor Tailwinds

New York stocks closed mixed on June 30, 2026, ahead of the first trading day of July. While buying interest flowed into artificial intelligence (AI) and semiconductor-related stocks, with the Philadelphia Semiconductor Index rising nearly 4%, the overall market movement was divergent due to adjustments in some tech stocks and other sectors. The stock price fluctuations of major tech companies on this day reflected investors' mixed assessments of the AI market's growth potential, as well as individual companies' performance and outlook. Even amidst the 'super bull market' trend that has continued since the beginning of the year, individual stock performance shows differentiation.

Nvidia was the focus of market attention on this day. Nvidia closed trading at 194.97 KRW, maintaining an overwhelming market capitalization of 4.72 trillion KRW despite a marginal gain of 0.01%. This was attributed to its unrivaled dominance in the AI chip market and explosive EPS growth rate (6599.3%). Intel, on the other hand, rose 0.03% to 131.72 KRW, showing potential with a high EPS growth rate of 9865.5%, although PER information was not provided.

Taiwanese semiconductor manufacturer TSMC rose 0.05% to 455.1 KRW. Despite a high valuation with a PER of 39.5 times and an EPS growth rate of 4430.2%, it continued its solid growth trend. Broadcom rose 0.02% to 372.45 KRW but carried a relatively high valuation burden with a PER of 62.1 times.

Alphabet (GOOGL), classified as an AI-related stock similar to Nvidia, rose 0.05% to 353.65 KRW, recording a market cap of 4.32 trillion KRW. It demonstrated high growth potential with a PER of 27.0 times and an EPS growth rate of 3419.4%. Its competitor, Meta Platforms, rose 0.02% to 562.6 KRW but showed concerns about slowing growth and declining profitability with a PER of 20.5 times and an EPS growth rate of -256.0%.

Apple fell 0.01% to 281.74 KRW, maintaining a market cap of 4.14 trillion KRW. While still showing high valuation and growth with a PER of 34.2 times and EPS growth of 2258.6%, its short-term stock momentum was limited. Microsoft fell 0.01% to 368.57 KRW, with a market cap of 2.74 trillion KRW, showing solid performance improvement with a PER of 21.9 times and EPS growth of 1551.4%. Amazon rose 0.03% to 240.14 KRW, recording a market cap of 2.58 trillion KRW and showing high growth with a PER of 31.6 times and EPS growth of 2879.9%.

Meanwhile, Tesla rose 0.08% to 411.84 KRW, with a market cap of 1.55 trillion KRW. However, it faced significant valuation pressure with a PER reaching 384.9 times and its EPS growth rate plummeting to -4709.0%. Micron Technology rose 0.01% to 1,145.28 KRW but, with a PER of 25.9 times, did not show clear momentum amidst the AI chip competition.

Market Impact and Investment Implications

The day's market trends highlighted the positive impact of AI technology advancements on the semiconductor industry as a whole, alongside clear differentiation in stock prices based on individual companies' competitiveness and growth strategies. In particular, the high EPS growth rates of AI chip-related companies, including Nvidia, reflect market expectations for future growth drivers. According to Yonhap News, a strong buying trend centered on AI and semiconductor stocks is also anticipated for the domestic stock market ahead of the first trading day of July, suggesting that these US market trends are influencing global markets.

However, the prevalence of growth stocks accompanied by high valuations calls for cautious investment. Tesla's extremely high PER and negative EPS growth rate, along with Broadcom's high PER, can be interpreted as warning signs of overheating. On the other hand, Microsoft, Alphabet, and Amazon demonstrate attractiveness as stable investment destinations by maintaining high growth rates and relatively reasonable valuations.

Furthermore, the movements of some ETFs are also worth noting. Vanguard S&P 500 ETF (VOO) and Invesco QQQ Trust, Series 1 (QQQ) recorded PERs of 26.6 times and 33.2 times, respectively, reflecting the overall market trend. This indicates that investment strategies through market index-tracking ETFs, in addition to individual stock investments, remain valid.

Future Market Outlook

The continuous development of AI technology and the growth of related industries are expected to continue positively impacting the stock prices of major tech companies in the future. Specifically, moves by companies like Anthropic, which is focusing on developing AI models such as ChatGPT and expanding its reach into the healthcare market through drug development programs, show the potential for AI technology to extend across various industries.

However, macroeconomic factors such as uncertainty regarding the timing of interest rate cuts by year-end and geopolitical risks could increase market volatility. Investors need to make investment decisions by closely analyzing individual companies' financial health, competitive advantages, and the actual applicability of AI technologies. In particular, the fact that companies like Intel are seeking opportunities for a comeback with high EPS growth rates signals that the competition for technological hegemony will intensify.

In conclusion, the second half of 2026 is expected to be a period demanding a cool-headed judgment of valuations and actual growth, with AI-centric growth themes continuing in the market.
