1. Why is AI investment so hot?
-
Market size explodes
The global AI market is estimated to exceed US$500 billion in 2026, with an annual growth rate of more than 30%
-
Enterprises invest heavily
Technology giants such as Microsoft, Google, Meta, and Amazon invest tens of billions of dollars every year to build AI infrastructure
-
From concept to profit
AI is no longer just a "future technology", it has begun to generate actual revenue and profits, and the investment logic has shifted from "imagination" to "performance"
-
Core of Taiwan's industrial chain
Taiwan’s semiconductor supply chain (TSMC, ASE, etc.) is a key link in global AI hardware
Important Notes
AI is a long-term trend, but in the short term individual stocks may pull back due to overvaluation. Be sure to do your homework before investing and don't blindly chase high prices.
2. Panoramic view of AI industry chain
| Hierarchy | Function | Represent the company | Investment logic |
|---|---|---|---|
| Chip design | GPU/AI accelerator | NVIDIA, AMD, Broadcom | “Shovel” for AI training and inference, demand continues to rise |
| Wafer manufacturing | Advanced process OEM | TSMC (2330), Samsung | The world’s most advanced AI chips are manufactured by TSMC |
| memory | HBM high bandwidth memory | SK Hynix, Micron, Samsung | AI computing requires large amounts of high-speed memory |
| Package testing | Advanced Packaging CoWoS | ASE(3711) | Advanced packaging is the key to improving AI chip performance |
| Server/Hardware | AI server assembly | Quanta, Wistron, Hon Hai | A large number of AI server orders drive revenue growth |
| Cloud platform | Computing resources provided | AWS, Azure, GCP | Provides infrastructure for AI training and inference |
| AI model | Large language model | OpenAI, Anthropic, Google | Most of them are still not listed, and their shareholders can participate indirectly through investment. |
| AI applications | end user products | Various vertical industries | AI applications in medical, financial, education and other fields |
Tip
- "Selling shovels to gold diggers" is the classic logic of AI investment. The certainty of upstream hardware is usually higher than that of downstream applications.
- Taiwanese investors have local advantages and can observe the dynamics of supply chains such as TSMC more closely.
3. Key targets of Taiwanese AI concept stocks

Important Notes
Investment in individual stocks is highly risky. The above is only a reference for industry analysis and does not constitute investment advice. Please make decisions based on your own risk tolerance and investment objectives.
4. Invest in AI themes with ETFs
| ETF | Tracking indices/strategies | management fee | feature |
|---|---|---|---|
| 00830 Cathay Philadelphia Semiconductor | Philadelphia Semiconductor Index | 0.52% | Covers major semiconductor stocks such as NVIDIA, AMD, and Qualcomm |
| 00757 Unified FANG+ | NYSE FANG+ Index | 0.71% | Contains large technology stocks such as NVIDIA, Meta, Apple, etc. |
| 00662 Fubon NASDAQ | NASDAQ-100 | 0.25% | U.S. technology stocks are concentrated, and AI leaders have a high weight |
| 0050 Yuanta Taiwan 50 | Taiwan 50 Index | 0.04% | TSMC has a weight of about 30-35% and is indirectly involved in AI |
| BOTZ (US stocks) | Global Robotics & AI ETF | 0.68% | Global AI and automation company, more fragmented |
| SMH (US stocks) | Semiconductor ETFs | 0.35% | In the global semiconductor industry, AI chips have a high weight |
Tip
- ETFs are lower risk than individual stocks and are suitable for long-term regular fixed investment
- Taiwan stock ETFs can be purchased directly with Taiwan dollars, no foreign currency account is required
- Investing in U.S. stock ETFs requires multiple commissions or an overseas brokerage account
5. Risks and Challenges of AI Investment
-
Valuation bubble risk
The price-to-earnings ratio of AI concept stocks is generally high. Once the performance is not as good as expected, the stock price correction may be severe. Lessons from the 2000 dot-com bubble are worth remembering
-
Technology iteration risk
AI technology changes extremely quickly, and today’s leaders may be replaced by tomorrow’s new technologies. For example, GPUs may be partially replaced by dedicated AI chips (ASICs)
-
regulatory risk
Governments around the world are tightening regulations on AI, and excessive regulation may affect the development speed and profitability of AI companies.
-
concentration risk
AI investment tends to be over-concentrated in a few companies (such as NVIDIA, TSMC) and lacks dispersion
-
geopolitical risks
Geopolitical factors such as the Sino-US technology war and the situation in the Taiwan Strait may affect the semiconductor supply chain
-
energy cost risk
AI computing consumes a lot of electricity, and rising electricity costs in the future may compress profits.
Important Notes
Don’t bet all your money on the AI topic. Even if you are bullish on the long-term trend of AI, keep your portfolio diversified.
6. AI investment strategy advice
-
Conservative: Indirect participation with large-cap ETFs
Regularly buy large-cap index ETFs such as 0050 or VTI. TSMC and major technology companies are already included, so no additional stock selection is required.
-
Robust: core + satellite strategy
70% of the funds are invested in large-cap ETFs (0050/006208), and 30% of the funds are allocated to AI theme ETFs (00830/00757), taking into account both stability and growth.
-
Active type: buy individual stocks directly
Based on in-depth research, select the most competitive stocks in the AI industry chain. However, a single stock shall not exceed 10-15% of the total investment position.
Tip
- Regular quota is the most suitable method for most people, and there is no need to judge the timing of entering the market.
- Make sure you have a 6-month emergency reserve before investing. Do not invest money you need urgently.
- Continuously learn and track industry trends, AI technology and business models are changing rapidly
