Core Insights - The first batch of floating fee rate funds has shown significant performance differentiation, highlighting the varying capabilities of fund managers in terms of positioning, sector allocation, and market judgment [1][9] Performance Overview - As of December 16, 2025, out of 26 funds, 19 achieved positive returns while 7 reported negative returns. The top performer, Huashang Zhiyuan Return A, delivered a remarkable return of 58.90%, followed by Xin'ao Advantage Industry A at 36.86% and E Fund Growth Progress A at 34.98% [2][10] - Other notable performers include Jiashi Growth Win A and Invesco Great Wall Growth, both exceeding 23% returns. Conversely, funds like Guangfa Value Steady A and Yinhua Growth Smart A reported negative returns of -8.32% and -3.35%, respectively [2][10] - The overall distribution of fund returns is characterized by a "middle large, both ends small" pattern, with most funds yielding between -0.1% and 7% [2][10] Fund Size and Performance Relationship - Notably, high-performing funds are not exclusively large. Huashang Zhiyuan Return A, with a size of 2.838 billion yuan, is the largest, while Jiashi Growth Win A, with a size of 406 million yuan, achieved a return of 32.88%, demonstrating the agility of smaller funds in volatile markets [2][10] Investment Strategies - Top-performing funds tend to focus on high-growth sectors. For instance, Huashang Zhiyuan Return A has concentrated holdings in AI computing-related stocks, with significant contributions from stocks like Zhongji Xuchuang and Shijia Photon, which saw increases of 45.39% and 40.17% over the past three months [3][11] - Xin'ao Advantage Industry A has a high concentration in semiconductor storage, with key stocks like Demingli and Jiangbolong rising by 55.43% and 119.02%, respectively. However, this strategy also led to volatility, as some holdings experienced declines of 13% to 21% [5][13] - E Fund Growth Progress A adopts a more balanced approach, diversifying across sectors such as optical communication and consumer electronics, successfully capturing gains from leading stocks [6][15] Underperforming Funds - Underperforming funds often remain focused on traditional industries or deviate from market trends. Guangfa Value Steady A has a significant allocation to liquor stocks, which have generally declined over 10% in the past three months, contrasting sharply with the strong performance of technology sectors [7][16] - Yinhua Growth Smart A is heavily invested in the real estate sector and certain pharmaceutical stocks, with some holdings experiencing declines as steep as 44.58%, indicating a lack of timely adjustments to market shifts [8][17] Conclusion - The short-term performance of the first batch of floating fee rate funds reflects a collision of different investment strategies and market styles in 2025. Funds aligned with the technology growth narrative performed strongly, while those focused on traditional value or balanced strategies lagged behind [9][17]
