Investment Myths of AI Leading Stocks: The Infrastructure Boom’s Ceiling

Many investors mistakenly believe that AI concept stocks can sustain high growth forever—but history offers harsh lessons. Cisco Systems (CSCO) during the internet boom hit a high of $82 in 2000, but after the bubble burst, it fell over 90% to $8.12. After 20 years, the stock still hasn’t returned to its peak.

Early infrastructure stocks are often overestimated: During the initial AI boom, upstream and midstream suppliers’ stock prices soared due to equipment demand, but high growth and market enthusiasm are hard to sustain long-term. Once infrastructure is built, growth naturally slows.

Downstream application stocks are not eternal winners: Giants like Microsoft and Google, despite ongoing commercialization advantages, saw their stock prices peak during bull markets and then fell sharply, struggling to return to previous highs. Yahoo was also a top company but was eventually overtaken by Google.

The key is timely rotation: In theory, continuously adjusting holdings can bring long-term benefits, but this is difficult for ordinary investors. Therefore, during phased investments, close attention should be paid to the speed of AI technology development, monetization ability, and whether individual stock profit growth is slowing.

Investment Strategies for AI Leading Stocks in 2025: Multi-Dimensional Allocation

Direct Stock Holding vs. Fund/ETF Trade-offs

Direct holdings: Concentrated risk but low cost, suitable for investors with stock-picking ability. Focus on short-term opportunities in chip manufacturers and infrastructure providers.

Stock funds: Managed by fund managers selecting a portfolio of stocks, balancing risk and return, with slightly higher transaction costs, suitable for conservative investors.

ETF products: Passive index tracking, lowest cost, most diversified risk. Products like Taishin Global AI ETF (00851), Yuan Tai Global AI ETF (00762) are now common institutional allocation tools.

The Necessity of Dollar-Cost Averaging

Using dollar-cost averaging to buy stocks, funds, or ETFs helps average purchase price and avoids errors from single judgment. This is the most prudent way to cope with short-term fluctuations in AI concept stocks, as capital flows shift among different companies. Continuous adjustment and staying current maximize performance.

AI Investment Outlook 2025–2030: Long-term Bullish, Short-term Volatility

With rapid advances in large language models, generative AI, and multimodal AI, demand for computing power, data centers, cloud platforms, and dedicated chips will continue to rise. In the short term, chip and hardware suppliers like NVIDIA, AMD, and TSMC will benefit most.

In the medium to long term, AI applications in healthcare, finance, manufacturing, autonomous driving, and retail will gradually land, translating into tangible revenue for more enterprises and driving overall AI leading stock growth.

Capital risk warrants attention: Although AI themes remain focal points, stock prices are inevitably affected by macroeconomic conditions. If the Federal Reserve adopts an easing policy, it will boost high-valuation tech stocks; if not, valuations may contract. Additionally, AI concept stocks are sensitive to news, prone to sharp fluctuations in the short term, and other themes like new energy may also cause capital shifts.

Policy and regulatory impacts: Many countries view AI as a strategic industry and may increase subsidies or infrastructure investments, providing positive support. However, issues like data privacy, algorithm bias, and copyright ethics could lead to stricter regulations. If regulations tighten, valuations and business models of some AI companies may face challenges.

Overall, AI leading stocks in the next five years will feature a “long-term bullish, short-term volatile” pattern. A more stable strategy is long-term allocation with phased entry, avoiding chasing highs in the short term to reduce market volatility impact. Prioritize chipmakers, accelerated server providers, or companies with tangible applications such as cloud services, medical AI, and fintech. Diversified investment via AI-themed ETFs can also effectively reduce risks from individual stock fluctuations.

Unavoidable Investment Risks

When investing in AI concept stocks, be aware of the following risks:

Industry uncertainty: Although AI has existed for decades, mainstream adoption is recent. Rapid changes and advancements occur, making it difficult even for knowledgeable investors to keep up. Investors may fall into hype-driven trading around individual stocks, experiencing significant volatility.
