Investors can judge whether a fund is an index fund by its name. If the fund name contains the words index, ETF, LOF, connection, etc. Then the fund is generally an index fund.

Index fund is a kind of fund that constructs a portfolio for securities investment according to the principle of compiling securities price index. That is to say, index fund is a passive fund, which has lower requirements for fund managers than active funds, so the management fee is also lower than active funds.
