The rise and fall of stocks are not determined by futures, but mainly by factors such as supply and demand, amount of funds, performance, policies and news. The rise and fall of futures is determined by the relationship between supply and demand, the amount of funds and the prices of related commodities. If futures plummet, but stocks are good for policies or news, then stocks will soar.
However, there is a certain connection between financial products. When the futures target rises, the related stocks will also rise. For example, when gold futures rise, the related gold stocks will also rise.
