Investment companies attract funds to invest in the securities industry to make profits, and guarantee companies make profits by financing guarantees for enterprises or individuals in banks.
Investment companies cooperate with financial derivatives such as securities companies and fund companies, while guarantee companies can only cooperate with banks.
Investment companies do not have the financing function, and guarantee companies cannot lend and invest with their own funds.
In the past, the state allowed investment guarantee companies to register, but now they must be separated, either to register investment companies or to register guarantee companies.
