E Fund's three-year holding period is a hybrid fund, and investors need to hold the fund for at least three years to redeem it. The purpose of this design is to encourage long-term investment, because long-term investment can better enjoy the growth income of the capital market and reduce the risks brought by day trading. Hybrid funds are composed of stocks, bonds and other assets, aiming at realizing long-term capital appreciation and stable income. According to their own needs, investors can choose to redeem their fund shares after holding them for three years to meet their capital needs or adjust their investment portfolio.
