Wide index funds are very suitable for ordinary investors who lack professional knowledge, but usually the returns are not very high and belong to long-term investment.

What is the corresponding broad index fund?

Generally, the fund corresponding to a broad index fund is a theme fund or a sector fund. Generally speaking, this kind of fund has a strong industry professionalism or concept, a narrow classification, a wide number of stocks and fewer base indexes. Under the same circumstances, theme and sector funds will rise or fall more than broad-based index, because their industries are more professional and more directly stimulated by news and policies, while broad-based index contains a large number of stocks in industries, so it is difficult for all industries to rise or fall at the same time, so it will be more stable.
