Group 1 - Multiple public fund companies have recently opened up fund share conversion services, allowing investors to convert shares directly without the need for redemption and re-subscription, thus improving capital efficiency and saving costs [1][2] - The main difference between fund share classes A and C lies in their fee structures; A shares are more suitable for long-term investors (over 1 year), while C shares are better for short-term investors (within 1 year) [2] - The conversion process can reduce the time taken for switching shares by 1 to 3 working days compared to traditional redemption and subscription methods, and it typically incurs lower fees [2][3] Group 2 - Investors should consider their investment goals and holding periods when using share conversion, as the original holding period does not carry over after conversion [3] - It is advisable for investors to calculate before converting, be mindful of timing, and avoid unnecessary frequent conversions to prevent resetting holding periods and incurring punitive fees [3]
