Whether foreign funds are suitable for long-term fixed investment depends on the type of fund. Actively managed funds are not suitable for fixed investment. Because actively managed funds have risks such as style drift or changing fund managers, they are not suitable for fixed investments.

Index funds are only suitable for fixed investment on the left side. After entering the right side, fixed investment will increase the cost, so they are not suitable for fixed investment on the right side. The return rate of long-term fixed investment in index funds is not high, so long-term fixed investment is not an excellent strategy. Actively managed funds have significantly outperformed index funds in their long-term median returns.
