3. Investment risks of index funds:

1. Risks brought by high positions

Index funds usually stipulate in the contract that stocks account for the fund The net asset ratio must not be less than 90%, which means that compared with the requirement that equity funds must not be less than 60%, once the market enters a unilateral decline, index funds will suffer more losses.

The losses caused by high positions are even more shocking. In any market, index funds have high positions and cannot avoid stock market risks through the operations of fund managers.

2. Risk of fund redemption

Although there are many categories of index funds, generally speaking, they follow market investment hot spots. Once the real economy fluctuates, many fund investors will redeem the funds, and there is a risk of fund redemption.

If you want to exit early, you have to sell at a low price and it is easy to lose money. Therefore, fund redemptions are risky for short-term operations.
