It doesn't matter, the fund will only reflect domestic A shares (I think you mean the Shanghai Composite Index instead of Nasdaq and NYSE in the United States) and will not react to commodities, futures and foreign exchange. However, due to the non-opening and openness of China's financial market, there is very little interaction with the international financial market. At present, the reason for the decline of A shares is the continuous interest rate increase, so the funds are falling, not a disaster. Disasters such as drought in the middle and lower reaches of the Yangtze River may have a great impact on the June contract of grain futures, but the Shanghai and Shenzhen indexes have no impact, and the news is very easy to be used by financial markets, which is called speculation. Some often insignificant factors are often hyped into immaterial positive or negative, which are used by speculators.
