Major A-share broad market indices experienced a decline this week. Reviewing the primary indices, the performance was broadly negative. The Shanghai 50, CSI 300, and Shanghai Composite Index saw relatively smaller losses, while the STAR 50, CSI 500, and ChiNext Index recorded more substantial drops.
Identifying Post-Drop Market Trends
The A-share market underwent a notable adjustment this week, with the Shanghai Composite Index falling over 3% on Friday, July 17th. The correction can be attributed to several concurrent factors. First, the rapid gains in the technology sector previously have created some profit-taking pressure. Second, a tightening macro environment, including a hawkish tilt in the Federal Reserve's interest rate policy and an unexpected rate hike in South Korea, has contributed to global liquidity constraints. Third, the previously pronounced market divergence between strong and weak sectors, coupled with the onset of the earnings season, has created an objective need for capital rebalancing. Finally, trading factors such as margin financing and quantitative strategies have further amplified market volatility during this period.
Historical data shows that following a single-day drop of more than 3% in the Shanghai Composite Index, the market tends to exhibit momentum for a rebound in both the short and medium term. After concentrated pessimism is released, the market typically stabilizes and gradually recovers. In samples since 2016, excluding extreme market conditions, the probability of a gain on the first subsequent trading day is 75.9%, with a median increase of 0.7%. From a medium-term perspective, the recovery trend is even clearer in a normalized market environment (post-2016). Twenty and sixty days after such a drop, the cumulative returns for the Shanghai Composite Index turn positive, with probabilities of 55.2% and 65.5%, and median gains of 2.0% and 1.7%, respectively.
Sector Performance Analysis
From a short-term perspective, consumer and certain manufacturing sectors have historically shown the highest probability and magnitude of rebound on the first trading day after a 3%+ drop in the Shanghai Composite. Based on normalized sample data since 2016, the beauty and personal care sector has been the most consistently resilient in the short term, with a 93.1% probability of rising on the first day and a median gain of 1.3%. Food & beverage and basic chemicals follow closely, with first-day rise probabilities of 79.3% and median gains of 1.6% and 0.9%, respectively. Sectors like building materials, household appliances, and pharmaceuticals & biotech also have first-day rise probabilities exceeding 70%, with median gains ranging from 0.9% to 1.4%.
In the medium term, the recovery potential for consumer and growth manufacturing sectors expands further from 20 to 60 days after a significant drop, offering both attractive returns and high success rates. According to normalized data since 2016, in the 20 days following a 3%+ decline, national defense & military industry, building materials, and beauty & personal care show the most pronounced rebound elasticity, with median gains of 7.9%, 4.7%, and 4.2%, respectively, and corresponding rise probabilities near or above 70%. Looking at the 60-day period, certain consumer sectors stand out. The food & beverage sector achieves a median gain of 9.8% with a 72.4% probability of increase. Beauty & personal care and social services post median gains of 4.9% and 4.7%, respectively, with probabilities nearing 70%. The electronics sector within growth manufacturing also demonstrates strong performance.
Market Outlook and Investment Focus
Consequently, the short-term market is likely to experience a gradual rebound. Attention should be paid to sectors that have historically performed well during market recoveries from oversold conditions, including national defense & military industry, building materials, beauty & personal care, food & beverage, electronics, and social services. From a medium-to-long-term perspective, as price transmission effects gradually materialize and industrial chain profitability continues to optimize, the trend of improving A-share corporate earnings is expected to persist, providing solid fundamental support for the market. Following the recent correction, the technology sector is poised for a recovery. For the medium to long term, focus should remain on three high-growth themes represented by hard technology: the export chain (power equipment, machinery), resource products (petroleum & petrochemicals, basic chemicals, non-ferrous metals, coal), and hard tech/AI (electronics, communications, national defense & military industry).
Risk Considerations
Key risks include: 1) Historical patterns failing to hold; 2) A significant deterioration in market sentiment; 3) Economic growth falling substantially short of expectations; 4) A major escalation in Sino-US relations; 5) A continued escalation of tensions in the Middle East.
