Today's Stock Market Trends on September 26, 2026, and Outlooks for the U.S. Stock Market and Semiconductors

1. New York Stock Market and Global Market Trends

1. New York Stock Market and Global Market Trends

Recently, the New York stock market has found a relatively stable flow as positive expectations for U.S.-Japan negotiations have spread. The sharp drop in international oil prices has reduced overall inflationary pressure, which has immediately served as a catalyst to boost investor sentiment. As warmth spreads across the market, AI-related tech stocks have once again led the rally. In particular, giants like Microsoft are driving technological innovation by evolving beyond simple chatbots into autonomous agents that work independently. These global market trends have a significant impact on the domestic stock market, making it essential to check overseas news every morning. In a time when the global economy is being rapidly restructured, it is necessary to monitor exchange rate fluctuations and raw material price trends simultaneously. This is because the domestic stock market, characterized by export-oriented companies, reacts very sensitively to external variables. When surrounding investors overreact to specific issues and engage in frequent trading, we should step back and read the broader trend. I vividly remember a painful experience where I panicked and cut my losses during a sudden exchange rate swing, only to deeply regret it later. Therefore, we need the wisdom to focus on the intrinsic value of companies and the broader direction of the global economy, rather than being distracted by short-term fluctuations reported in the news.

💡 Key Point
Global stock markets are showing signs of recovery driven by tech-led innovation and the stabilization of external variables.

2. Semiconductor Market Boom and Memory Industry Outlook

2. Semiconductor Market Boom and Memory Industry Outlook

Experts predict that the semiconductor boom will continue for a considerable period, and that the status of memory semiconductors will change completely. In the past, they were close to consumable goods simply mass-produced and sold, but now they serve as the core brain of the AI era, with their value skyrocketing. Even amidst the competitive landscape with global companies like TSMC in Taiwan, major domestic companies are staking everything on narrowing the technological gap. Looking at recent movements in Samsung Electronics’ stock price, fierce battles are unfolding over strong resistance lines amid subsidy benefits and competitor risks. For general investors, closely observing the chart trends and supply-demand changes of such large-cap stocks is the shortcut to successful trading. There is also a high possibility that the performance of suppliers providing semiconductor equipment and materials will rise in tandem, so it is worth keeping an eye on small and medium-sized component stocks. When rumors circulate that semiconductor stocks are nearing their end, a reversal often occurs as institutional and foreign investors step in to buy. In fact, a friend of mine who bought high-quality semiconductor component stocks last year, despite warnings from others, achieved substantial returns. This shows that a contrarian investment strategy, moving against public sentiment, can sometimes be the most powerful weapon. Now that the memory semiconductor supercycle is fully underway, we should seriously consider how to adjust the semiconductor allocation in our portfolios.

💡 Key Point
The semiconductor industry has entered a long-term boom phase driven by AI demand, and the value of memory is being re-evaluated.

3. The Convergence of Artificial Intelligence and Power Grid Infrastructure

With the surge in AI data centers, large-scale projects to replace power grids and connect renewable energy sources are continuing worldwide. This is why power-related companies like Iljin Electric are receiving daily attention; it is directly tied to this massive historical trend. Because enormous capital is being invested in building intelligent power grids beyond simply supplying electricity, earnings growth is guaranteed. Not only in the U.S. but across Europe, efforts to modernize aging power infrastructure are accelerating, expanding the export territory for domestic companies. In the stock market, the real big wins often come not from obvious stocks that everyone knows, but from infrastructure-related stocks that quietly build up their performance in the background. An investor I know focused on power equipment companies that supply electricity to data centers rather than the data centers themselves during the AI boom, achieving significant results. Their insight in identifying the infrastructure essential to the real economy, while everyone was looking only at flashy software companies, was the key to their success. Even now, order announcements related to power grid replacement are being released continuously, so we must always keep an antenna up for related news. If individual stock analysis is too difficult, using Exchange-Traded Funds (ETFs) that hold a balanced mix of related companies is also a wise approach. If we can grasp the context of where money is flowing in the changing industrial structure, even ordinary office workers can survive in the market.

💡 Key Point
Due to the expansion of AI data centers, power grid replacement and infrastructure-related companies are emerging as new leading stocks.

4. Asset Allocation and Exchange-Traded Fund (ETF) Investment Strategies

In times of high stock market volatility like now, asset allocation through Exchange-Traded Funds (ETFs) is strongly recommended over going all-in on individual stocks. ETFs, which are listed on securities markets and traded in real-time like stocks, are one of the safest wealth management tools for beginner investors. They offer the advantage of diversifying into quality indices or sectors without the complex redemption procedures or high fee burdens associated with funds. The era of sticking to only domestic or U.S. stocks is over; we must appropriately mix quality assets from both markets. I myself found peace of mind after allocating a significant portion of my assets to U.S. index ETFs and domestic dividend stocks. Looking around, I often hear sad stories of people who treat stock investing as a complete gamble, putting in a large sum at once and getting hurt. Systematic investing using ETFs significantly reduces such risks, helping office workers grow their assets while staying focused on their main jobs. We can create a virtuous cycle of buying more at lower prices when the market falls and realizing profits when it rises. If you lack the time to analyze complex economic indicators daily, consistently accumulating products that track reliable indices is the right answer. A wise investor does not rely on luck but believes in the system, knowing how to enjoy the magic of compound interest through consistent accumulation.

💡 Key Point
In volatile market conditions, diversified investing and systematic asset allocation using ETFs are the safest alternatives.

5. The Correlation Between Safe Assets and Gold Prices

Gold is the quintessential safe asset that invariably draws attention whenever the stock market shows signs of instability, and recent gold prices are also on a high run. The fact that the selling price of one won of pure gold (a Korean unit of weight) remains at a high level as of Saturday is proof of the significant uncertainty in the global economy. As volatility in the securities market increases, there is a clear tendency for investors to reduce their exposure to risky assets and turn to physical assets or gold. In fact, I often seriously consider whether I should shift my focus to gold or safe bonds whenever I see red in my stock account. Allocating a portion of assets to gold serves to robustly defend the overall portfolio in emergency situations where the stock market crashes. Gold is an excellent investment target that has been proven over a long period not only as a safe asset but also as an inflation hedge. We enjoy various investment options today on the economic foundation built by our predecessors through hardship, blood, and tears. Compared to that era, financial products allowing the purchase of gold in small units are now well-established, significantly lowering the barrier to entry. It is hard to bear the rapid heartbeat if one builds an account solely with stocks, so a certain percentage of total assets must be allocated to safe assets like gold. Understanding and practicing the value of gold, which shines even when the market shakes, is the asset management method of a true master.

💡 Key Point
As stock market instability intensifies, gold plays a crucial role as a safe asset that reduces portfolio volatility.

6. Overall Review of Today’s Stock Market and Future Response Strategies

Today’s stock market on September 26, 2026, is preparing for a new leap, using its first upward trend in four weeks as a stepping stone amid intersecting external headwinds and expectations. The semiconductor boom, the expansion of AI power grid infrastructure, and thorough asset allocation are the key weapons to overcome the market ahead. Rather than being elated or distressed by immediate stock price fluctuations, we must focus entirely on the intrinsic value and future growth potential of the companies we invest in. Let us remember that only investors who stick to principles without being swayed by rumors will ultimately see smiles in their accounts. I sincerely hope that the various market news and strategies shared today will enrich your wise investment life. There are many significant variables that will affect the stock market in the remaining second half of the year, such as the direction of interest rates and global supply chain issues. In such times, it is essential to maintain an appropriate cash ratio and have the flexibility to buy whenever a good opportunity arises. Instead of staring at charts day and night, I encourage you to take time to recharge on weekends and review the broad trends of the macroeconomy. There is no such thing as a failure-free investment, but the process of turning failures into fertilizer for growth and completing your own investment principles is success itself. I hope you will protect and grow your precious assets safely through calm and wise trading next week as well.

💡 Key Point
Thorough asset allocation based on strict principles and a long-term perspective is the only path to victory in a highly volatile stock market.
