When buying funds, you must insist on long-term investment. Returns and risks are positively correlated. There is no investment project in the world that has high returns but low risks! Fund fixed investment means insisting on long-term investment, entering the market in installments, and sharing buying risks and holding costs. Therefore, it is better to choose funds with greater volatility. I suggest that index funds are the first choice for fixed investment and share the growth of the Chinese economy!
