A-Shares Rebound Broadly: Is It Time to Buy the Dip?

Preface

China’s A-share market staged a broad rebound on October 28, with growth-focused indexes leading the advance and trading activity picking up. The rally followed a period of market weakness and came as investors weighed whether recent declines had created an opportunity to buy at lower prices. This article reviews the day’s market performance, the factors behind the shift in sentiment, and the signs some analysts interpret as evidence of a potential market bottom. It also considers company buyback and share-purchase announcements, valuation and positioning indicators, and sectors that may attract attention if the recovery continues. A one-day rebound does not confirm that a sustained uptrend has begun, so the discussion distinguishes observed market data from analyst expectations. The central question is not simply whether prices have fallen, but whether valuations, fundamentals, and risk appetite together support a more durable recovery.

Lazy bag

On October 28, A-shares rose broadly: the ChiNext gained 3.4%, the Shenzhen Component Index climbed 2.02%, and more than 4,100 stocks advanced. Turnover reached 1.63 trillion yuan, up 167.5 billion yuan from the previous trading day. Analysts cited lower valuations, reduced trading crowding, ETF inflows, and company buybacks as possible signs of market stabilization. They also highlighted high-quality, oversold businesses with reasonable valuations, including selected domestic computing-chip, overseas PCB and optical-chip, and semiconductor-equipment companies. The rebound may offer an opportunity, but it is not proof that market risk has disappeared.

Main Body

On October 28, China’s A-share market rebounded after opening higher, with the ChiNext and STAR 50 indexes among the stronger performers. At the close, the Shanghai Composite Index was up 0.91%, the Shenzhen Component Index rose 2.02%, and the ChiNext Index gained 3.4%. The Shenzhen Component and STAR 50 indexes both advanced by more than 2% during the session, while the ChiNext rose by more than 3%. The broad advance was reflected in market breadth: more than 4,100 listed stocks finished higher.

Trading activity also expanded. Turnover across the Shanghai and Shenzhen markets totaled 1.63 trillion yuan, an increase of 167.5 billion yuan compared with the previous trading day. Higher turnover alongside rising prices can indicate stronger participation, although it cannot by itself establish that a lasting trend reversal is underway. Market performance remained uneven beneath the headline gains, and investors continued to respond quickly to changing themes.

Among the day’s active areas, humanoid-robotics stocks surged, while short-form drama-related shares were also lively. Innovative drugs and contract research organization, or CRO, shares moved higher during the session. In contrast, food and beverage stocks traded lower. The rotation between popular sectors showed that investors were seeking opportunities in selected themes rather than buying every industry indiscriminately.

Several individual stocks drew attention. Lianxun Instruments returned to the 1,000-yuan share-price category, while Unitree Technology rose by more than 8% and Zhongji Innolight jumped by more than 10%. Unitree Technology had also shown strong momentum in recent weeks, with its cumulative gain since October exceeding 54%. These individual moves stood out against a market that had recently been affected by subdued investor sentiment.

The rebound raised a familiar question: has the market reached a level where investors can begin buying the dip? The article’s market commentary points to signs of a possible base-building process. Major indexes rebounded sharply, trading volume increased, and analysts observed that the preceding adjustment had already been substantial. Based on past market behavior, they argue that a period of recovery could be approaching, potentially creating room for a meaningful correction upward. These are assessments rather than guarantees; a short-term rally may still be followed by renewed volatility.

Corporate actions have offered another indication of confidence. On the evening of October 27, a growing number of companies listed in Shanghai and Shenzhen disclosed share-repurchase or share-purchase plans. The companies named included Sugon, Gree Electric Appliances, Dingtaigao, and Jufei Optoelectronics. According to Wind data, since October, more than 120 additional companies had disclosed repurchase or share-purchase plans. A number of leading companies across industrial supply chains were among those taking action, committing capital in a way that can signal confidence in their businesses and valuations.

Analysts cited by securities firms have attributed the market’s adjustment since July primarily to valuation pressure and the release of external risks, rather than to a fundamental reversal in industrial prospects. In their view, changing expectations for Federal Reserve rate hikes and rising U.S. Treasury yields have weighed on global equity valuations. Escalating geopolitical tensions have also affected investor risk appetite. These factors can pressure share prices even when the longer-term outlook for particular industries remains intact.

At the same time, some analysts believe several indicators now show characteristics associated with a market bottom. First, valuations have fallen to relatively low levels. For growth sectors such as artificial intelligence, where the industrial trend is clear and earnings are accelerating, lower prices may make valuations more attractive. This does not mean every company in a popular theme is inexpensive; company-level earnings and valuation still matter.

Second, index volatility has risen to a high level. Analysts point to the possibility of mean reversion, whereby unusually elevated volatility may eventually subside. Volatility, however, can remain high for an extended period, and this indicator is most useful when considered alongside other evidence rather than as a stand-alone timing signal.

Third, the recent adjustment has reduced some of the crowding in popular sectors. When too many investors hold similar positions, a shift in sentiment can trigger concentrated selling. A less crowded market may have a healthier positioning structure, though it does not eliminate the possibility of further declines or guarantee renewed demand.

Fourth, from an asset-allocation perspective, the risk premium of the CSI 300 Index has moved above its 3-year moving average. The comparison suggests that equities may offer more attractive relative value than bonds at current levels. Investors still need to consider their own time horizon and risk tolerance, since relative attractiveness does not ensure positive returns.

Fifth, exchange-traded funds, or ETFs, have seen substantial net inflows. Historical experience cited by analysts suggests that large inflows into equity ETFs have often coincided with temporary market bottoms. Continued inflows may support confidence and help absorb liquidity shocks. Still, flows can change, and ETF purchases do not independently confirm that a recovery will persist.

Against this backdrop, investors are considering which areas might benefit if a rebound develops. Analysts emphasize the combination of strong earnings, significant prior declines, and reasonable valuations as a potential basis for identifying opportunities. The third-quarter earnings reporting period is under way, making company results and forward guidance especially important. Businesses with solid fundamentals and strong industry conditions may be better positioned to stabilize than companies whose share prices depend primarily on sentiment.

One securities firm characterizes the adjustment as a temporary episode of liquidity pressure rather than a fundamental reversal in industrial momentum. Technology stocks are particularly sensitive to changes in liquidity and risk appetite, so they may show greater price elasticity if the broader market stabilizes. After crowded positions have been reduced, technology shares with credible earnings and industry support could attract renewed interest. This potential upside comes with corresponding volatility and should not be confused with a low-risk opportunity.

Analysts’ areas of interest include domestic computing-power chips, PCB and optical-chip businesses linked to overseas supply chains, and leading semiconductor-equipment companies. These are broad industry branches, not recommendations to buy every stock within them. Investors assessing individual companies may examine revenue and earnings trends, competitive position, valuation, balance-sheet strength, and exposure to external risks. The day’s rally provides a reason to reassess conditions, but investment decisions depend on whether business fundamentals support current prices.

Overall, October 28 brought clear evidence of a broad rebound: major indexes rose, market breadth was positive, turnover increased, and several growth-related themes advanced. Buyback announcements, lower valuations, less crowded positioning, and ETF inflows have added to the case for stabilization. Yet the key question remains open. A durable recovery would require continued market participation and confirmation from company earnings, not simply one strong trading session. Investors weighing a dip-buying strategy may therefore distinguish between evidence of improving conditions and expectations that still carry uncertainty.
