When the index fund is overvalued and sold, it is not recommended to continue buying. Because the valuation is already very good, if there is a correction in the market, then investors will suffer losses. If the valuation returns, it is difficult to rise in the short term.

Investors can consider watching or allocating some actively managed funds. Because actively managed funds do not completely follow the trend of the index. Even if the index is adjusted back, the adjustment range of actively managed funds may not be as large as the index, because fund managers will switch positions and exchange shares.
