LOF index funds, such as Harvest 300 Fund, are the same as general index funds: they are all index funds, and they all track an index.
The difference is that ordinary funds can only be traded over the counter, such as buying and redeeming in banks; LOF funds can be traded on and off the market, that is, in addition to trading like ordinary funds, they can also be traded in securities companies with shareholder accounts.
Etf funds, like LOF funds, can also be bought and sold like stocks, but a package of stocks must be used for purchase and redemption, which has the advantage of making ETF funds track more accurately. However, the disadvantages it brings are: the starting point of purchase and redemption is too high for ordinary investors to invest.
So ETF Linked Fund was born. Etf Linked Fund invests money in the etf it contacts, so the trend of ETF Linked Fund's net value is consistent with the underlying index. At the same time, the investment threshold of etf-linked funds is lower than that of etf funds, which, like ordinary funds, allows ordinary investors to invest.
