On April 20, China's A-share market demonstrated robust performance, with the Shanghai Composite Index advancing toward the 4100-point level and the Beijing Stock Exchange 50 Index rising over 1%. Leading the gains were sectors including lab-grown diamonds, ultra-high voltage power transmission, satellite internet, and commercial aerospace. More than 3,400 stocks climbed across the A-share market, with 90 hitting their daily upside limit. Trading volume expanded significantly, reaching 2.61 trillion yuan for the day. Market sentiment remained optimistic, as evidenced by a surge of over 550 billion yuan in margin lending balances the previous week. On April 20 alone, more than 2,200 stocks recorded net inflows from major institutional funds.
Analysts attribute the market's upward trajectory to improving economic indicators, sustained accommodative liquidity conditions, and the growing appeal of renminbi-denominated assets, which together form a solid foundation for medium-term A-share performance. The latter part of April represents a critical period for validating corporate earnings recovery, presenting opportunities for strategic sector allocation.
Market momentum continued to build on April 20, with the Shanghai Composite Index reaching its highest level since early April. The ChiNext Index approached 3700 points during the session, marking its strongest position in nearly 11 years. At the close, the Shanghai Composite, Shenzhen Component, STAR Composite, and Beijing Stock Exchange 50 indices rose 0.76%, 0.55%, 0.73%, and 1.12% respectively, while the ChiNext Index edged down 0.02%. The Shanghai Composite settled at 4082.13 points, with the ChiNext Index finishing at 3677.58 points.
Daily turnover reached 2.61 trillion yuan, an increase of 153.6 billion yuan from the previous session. Advancing issues outnumbered decliners by 3424 to 1898, with 90 stocks hitting their upper limit and 17 falling to their lower limit.
Sector performance showed particular strength in lab-grown diamonds, ultra-high voltage, satellite internet, and commercial aerospace. Among Shenwan primary industries, defense, electronics, and utilities led gains with advances of 3.47%, 1.56%, and 1.35% respectively. Conglomerates, building materials, and coal mining lagged, declining 1.44%, 0.60%, and 0.43%.
Notable movers included Guanglian Aviation, which surged over 11%, while China Satellite Communications, Boyun New Materials, China Satellite, and Songfa Group all reached their daily limits. Several defense stocks with commercial aerospace exposure have shown sustained strength, with the commercial aerospace sector gaining over 10% since April began.
In the electronics sector, Shanghai Sinyang Silicon Technology jumped more than 14%, with ASR Microelectronics and Maolai Optical both rising over 13%. Espressif Systems and Baibang Technology gained over 11%, while Gaohua Technology advanced beyond 10%. Heli Tech, Founder Technology, and Caihong Group were among stocks hitting their upper limits.
Margin lending activity intensified, with balances increasing by over 550 billion yuan last week. Since April 8, daily turnover has exceeded 2 trillion yuan for nine consecutive sessions. Wind data showed that as of April 17, combined margin lending balances reached 2.671 trillion yuan, with the financing balance alone standing at 2.651 trillion yuan. The financing balance expanded for five straight days, accumulating an increase of 556.98 billion yuan.
Sector-wise, 24 of 31 Shenwan primary industries saw increased margin lending, with electronics, power equipment, and communications recording the largest net purchases at 157.09 billion, 107.30 billion, and 78.62 billion yuan respectively. Non-bank financials, banking, and construction materials experienced the largest net selling at 7.59 billion, 3.40 billion, and 3.02 billion yuan.
At the individual stock level, margin traders increased positions in 207 stocks by more than 1 billion yuan each. Zhongji Innolight, Contemporary Amperex Technology, Hikvision, Dongshan Precision, and Huayou Cobalt saw the largest additions at 41.79 billion, 25.34 billion, 13.46 billion, 10.80 billion, and 10.38 billion yuan respectively.
Despite the bullish trend, some profit-taking emerged. Net outflows from major funds totaled 6.81 billion yuan on April 20, with the CSI 300 seeing outflows of 2.128 billion yuan. While 2,215 stocks registered net inflows, 2,970 experienced outflows.
Among sectors, 11 industries saw net inflows, led by defense, media, and electronics with 3.551 billion, 1.329 billion, and 1.329 billion yuan respectively. Communications, basic chemicals, and nonferrous metals led outflows with 5.051 billion, 2.117 billion, and 1.542 billion yuan, indicating profit-taking in the previously strong communications sector.
Luxshare Precision, Inspur Information, and Envicool attracted the largest inflows at 4.612 billion, 1.195 billion, and 1.016 billion yuan, while Dongshan Precision, Zhongji Innolight, and Contemporary Amperex Technology saw the biggest outflows at 2.883 billion, 2.271 billion, and 1.875 billion yuan.
According to Qiu Xiang, Chief A-Share Strategist at CITIC Securities, active capital represented by leveraged funds and small-to-medium私募 funds still has room to increase positions following the rapid rebound.
Yang Chao, Chief Strategist at China Galaxy Securities, identified three market focuses: reduced external risks, rising inflation expectations, and renminbi exchange rate support. He noted the market is transitioning from避险trading and sentiment-driven speculation to structural themes centered on earnings recovery and industrial trends. While geopolitical tensions and oil price volatility remain concerns, positive economic data, loose liquidity, and renminbi asset attractiveness provide core support for medium-term A-share performance. The concentrated disclosure of annual and quarterly reports in late April offers a key window to verify earnings recovery, highlighting selective allocation opportunities.
Wang Zheng, General Manager of Shangyi Fund, attributed recent gains to the combined effect of liquidity, fundamentals, and external conditions. The overnight repo rate remained low at 1.2%-1.25%, with the 7-day reverse repo rate steady at 1.40%, indicating ample liquidity. First-quarter GDP growth of 5.0% and strong pre-announcements from AI and semiconductor companies supported fundamentals. Improved global risk appetite from easing geopolitical tensions and foreign capital returning to A-shares reinforced upward momentum. While the medium-term outlook remains positive, short-term structural divergence and consolidation warrant caution.
Zhang Xia, Chief Strategist at China Merchants Securities, observed rapid risk appetite recovery in April, with short covering helping multiple assets recover losses since the Middle East conflict and even reach new highs. U.S. stocks, A-shares, and the renminbi showed particular strength. Stable domestic growth coupled with enhanced safety premiums for Chinese assets may attract foreign capital back, providing fundamental and liquidity support over the medium to long term. For allocation, he recommended focusing on sectors with strong first-quarter earnings growth, including nonferrous metals, petrochemicals, new energy, optical communication, and semiconductors.
