With the rising price of crude oil, more funds poured into crude oil funds, resulting in a substantial premium in the secondary market price of crude oil funds, and some fund companies have warned of risks. Affected by the risk warning, on February 28th, Guangfa Dow Jones American Petroleum Development and Production Index Securities Investment Fund (QDII-LOF) stopped trading in the secondary market, but even so, there was still a premium of over 10%.

The decline of crude oil theme funds may be related to the cautious participation of funds. Oil prices may fluctuate at a high level in the afternoon, and some funds choose to take profits.
