A-Share Market Pulls Back as AI Sector Faces Pressure: Opportunities and Risks Coexist Among Limit-Up Stocks

All Three Major Indices Pull Back as AI Sector Divergence Intensifies

On April 28, the A-share market underwent a notable correction. By the close, the Shanghai Composite Index fell 0.19% to 4,078.64 points; the Shenzhen Component Index dropped 1.10% to 14,830.46 points; and the ChiNext Index declined 1.43% to 3,596.71 points, marking its fourth consecutive daily loss. Combined turnover across the Shanghai, Shenzhen, and Beijing exchanges totaled 2.55 trillion yuan, shrinking by 54.3 billion yuan from the previous trading day, signaling a rise in wait-and-see sentiment.

Against this backdrop, the AI technology sector — which had been consistently active in recent sessions — was not immune to the downturn. Divergence within the sector became increasingly pronounced. While some sub-segments still produced limit-up stocks, overall enthusiasm cooled compared to earlier sessions.

AI Investment Clues Among Limit-Up Stocks

Despite the broader market pressure, AI-related concept stocks were still visible among the day's limit-up names. Based on sector distribution, the key investment threads included:

AI Application Implementation: As large language model technology continues to evolve, AI applications in vertical sectors such as education, healthcare, and finance are accelerating their real-world deployment, attracting capital inflows. Market expectations for "AI + Industry" themes continue to build, with companies poised to deliver tangible earnings performing relatively well.

Computing Infrastructure: Driven by sustained overseas demand for computing power and the domestic substitution narrative, stocks in the computing power supply chain — including optical modules, servers, and liquid cooling — continue to attract attention. However, disagreement over high-priced names is growing.

Robotics and Embodied Intelligence: Humanoid robot concepts have been repeatedly active in recent sessions, with upstream and downstream companies frequently appearing on limit-up lists, reflecting the market's long-term optimism toward this segment.

Risk Warning: Shrinking Volume Signals Should Not Be Ignored

However, chasing limit-up stocks in the current market environment carries significant risks. Several signals urge investors to remain cautious:

First, trading volume continues to shrink. The 2.55 trillion yuan turnover represents a contraction of over 50 billion yuan from the previous day, indicating weakening willingness among incremental capital to enter the market. In a low-volume environment, limit-up stocks often lack follow-through, and next-day premiums may decline significantly.

Second, the ChiNext's four-day losing streak is a warning sign. As a bellwether for growth and technology stocks, four consecutive declines on the ChiNext Index suggest that short-term risk appetite is shifting downward. As a quintessential growth sector, AI faces valuation correction pressure during this phase.

Third, sector rotation is accelerating. Recent hot spots within AI concepts have been shifting rapidly — from computing power to applications, from large models to robotics — with capital exhibiting a clear "hit-and-run" pattern. Chasing rallies makes investors vulnerable to gap-down openings the next day.

Fourth, some stocks show signs of speculative overheating. Certain AI concept stocks have already seen substantial short-term gains detached from fundamental support, driven purely by sentiment and speculative capital flows. Once the tide turns, pullbacks may exceed expectations.

Market Outlook: Short-Term Volatility Won't Alter Long-Term Trends

From a longer time horizon, the AI industry's development trajectory has not been altered by short-term market fluctuations. Globally, the large language model race continues to intensify, while domestic players are making continuous breakthroughs in open-source ecosystems and industry applications, providing solid fundamental support for related listed companies.

Analysts point out that the current market correction is more of a technical pullback following rapid earlier gains, rather than a trend reversal. For investors, it is advisable to manage position sizes in the short term and avoid blindly chasing limit-up stocks. Over the medium to long term, attention should be directed toward core AI assets with genuine earnings delivery capabilities, seeking entry opportunities during pullbacks.

It should be emphasized that limit-up stock investing is inherently high-risk. Investors should make rational decisions based on their own risk tolerance and avoid being swept up by short-term emotions. Markets carry risks, and investment requires caution.
