Index investment shows a trend of precision "from broad to detailed", institutional professionals warn of intensified fluctuations in the AI track.

With the continued active market, industries such as AI, innovative drugs, and securities have shown impressive performance, and the trend of index investment is quietly changing. Since August, funds have gradually flowed from broad-based index ETFs to industry, theme, and strategy-based index ETFs, showing a trend of precise investment "from broad to narrow." "Currently, Cambricon has become the anchor of the A-share artificial intelligence sector," said a research analyst at a securities firm. However, after continuous substantial gains, whether this track is currently overly crowded has become a concern for investors. Many institutional professionals believe that the leading position of the AI sector is the result of the resonance of policy, technology, and demand, and its long-term investment value still exists, but in the short term, one must be cautious of the valuation bubble and the risk of capital speculation.
