Core Viewpoint - Since May, public fund institutions have been actively announcing the addition of new share classes for their funds, as well as enabling the conversion of different share classes within the same fund, which enhances product competitiveness and meets diverse investor needs [1][2][4]. Fund Share Addition - Fund institutions are increasingly adding new share classes, such as C, D, and E shares, to cater to varying investor preferences regarding fees and investment horizons [2][3]. - For instance, on May 28, Xingyin Fund Management announced the addition of C and E share classes for its Xingyin Jufeng Bond Fund, while the original shares were converted to A shares [2]. - The fee structures differ among share classes, with A shares charging subscription fees but not service fees, while C and E shares do not charge subscription fees but have different service fee rates of 0.15% and 0.20% respectively [2][3]. Share Conversion Channel - Several public fund institutions, including Changxin Fund Management and Guohai Franklin Fund Management, have opened conversion channels for different share classes, allowing investors to switch shares based on their investment strategies [4]. - This conversion capability enhances liquidity for investors, reducing transaction costs and time by eliminating the need for redemption before subscription [4]. - The addition of share classes and conversion features is expected to attract more investors, particularly those sensitive to fees or with specific needs, thereby increasing market share for the funds [4].
