Recently, Guotai Junan's 2025 strategy meeting will be held in Shenzhen. The conference made an in-depth discussion and comprehensive outlook on the hot topics of market concern and the investment strategy in 2025. Fang Yi, chief strategist of Guotai Junan, said in an interview that the bottom of the A-share market has emerged, which is optimistic about the prospects of China stock market. The key driving force for the market to start comes from the decline of risk-free interest rate and the boost of risk preference. After a long period of continuous adjustment, the pessimistic expectation and microstructure of A-shares are fully clarified, and the positive signal of decision-makers to steady economic growth and support the capital market is an important cornerstone for the upward revision of long-term expectations and the elevation of the bottom of the stock market. Looking forward to the A-share market in 2025, Fang Yi said that there is still room for the optimistic policy expectation at the end of the year and the beginning of the year, and A-shares are expected to go out of the New Year's market. However, in the case of rising geopolitical conflict risks, the stock index may face a staged headwind. However, as the market stabilizes and revises the economic and policy expectations, the stock index is expected to strengthen again in the second half of 2025. (shanghai securities news)
