Index fund is a kind of stock fund that invests in the basic index, through which investors can buy one or more stock portfolios, thus gaining income in the financial market. This kind of fund can be traded on or off the market. The difference is that the on-market fund can be traded on the market or in the day, while the off-market fund is sold in the fund company and traded in the form of T+ 1.

The second paragraph: the investment methods, advantages and disadvantages of index funds on and off the market

For OTC funds, it is usually necessary to purchase, redeem and trade through fund institutions (such as banks and securities companies). Although the scale is large and there are many kinds, the transaction speed is slow and there may be higher sales expenses. On-site funds can be traded faster and at lower cost, but they can only be bought and sold on exchanges.

The third paragraph: the characteristics and development trend of on-site fund trading

The price transparency of listed index funds is higher, and the relationship between market supply and demand is more obvious, which is convenient for investors to analyze and make decisions. Traditional financial institutions and new financial technology companies have entered the index fund market, leading the market development trend. In the future, index funds traded in the market are expected to be recognized by more investors and become an important member of diversified portfolios.
