With the hot sales of SDIC UBS Ruifu Grading Fund and ICBC Credit Suisse Bonus Stock Investment Fund last week, the innovation fund finally came to the foreground from behind the scenes.

Experts in the industry said that the three innovative funds launched this time have carefully designed schemes such as "graded fund", "lifeboat clause" and "one-year closed period", which have many innovations in fund investment targets, income distribution, governance structure, rate structure or management mode, which is conducive to overcoming some limitations of the original closed-end funds and giving fund investors more choices.
