Active fund refers to the fund manager's subjective initiative, relying on his latest talents to manage the fund, which is mostly used with ordinary stock funds, hybrid funds and bond funds.

Passive fund refers to the fund manager relying on index, simply copying, or relying on computer quantitative model, without manual active management, but completely copying, using computer programs to complete the investment.

The main difference between the two is whether there is anyone to manage the fund. Although the passive type has a fund manager, it is only responsible for data maintenance and major issues, and generally does not directly interfere with the fund operation. The advantage of passive funds is to exclude human factors and earn as much as the index earns. Simply investing in tools does not require investors to consider the factors of fund managers, but only needs to judge whether the index has a chance. Active funds rely on the ability of fund managers, who have great influence and directly determine the performance of funds, which may be better than the index or lower than the index.
