Citic sec's research reports indicate that with the continued strengthening of support policies for mergers and acquisitions since 2024, the A-share market is expected to usher in a major era for mergers and acquisitions. Special attention should be paid to the two major directions represented by state-owned enterprises in traditional industries and technology enterprises represented by the szse sme 300 growth index. Listed companies can achieve external growth through mergers and acquisitions, and merger and acquisition events generally have a positive effect on the stock prices of A-share listed companies acting as bidders.
