If you want to cover your position, you need to see where the fund you bought is. If it falls at a high point, you may have bought the wrong one. If it falls to a low point, you can increase your position. After the fund falls, don't rush to cover the position, but consider whether to sell it according to the actual situation. If your money is not urgent, you don't have to make up the position or sell it.
Funds are indirect investments. Everyone saves money and gives it to the fund manager to invest in stocks, bonds, currencies, etc. Generally, the funds we buy will be affected by the market or related sectors. Because the level of fund managers is uneven, there are also cases that deviate from the broader market. This varies from person to person and is not specifically discussed.
