Core Viewpoint - The article discusses the impending expiration of the broker's large collective asset management products, which have significantly decreased in scale over the years, indicating a major shift in the asset management landscape in China [2][3][4].

Group 3: Current Status and Future Outlook - As of December 2023, the remaining products are primarily set to expire in 2025, with one product having received an extension into mid-2026 [4][8]. - The trend indicates a significant shift towards public fund structures, reflecting a broader move in the industry towards more regulated and transparent investment vehicles [6][7].
