What does a securities finance company do? Where do the funds and securities come from? Not for profit?

Controversial securities finance companies help customers invest in some financial products, such as stocks and futures. Because most securities companies help customers buy stocks, the money is given by customers. Some companies will also hand over their shares to securities companies for them to sell on their behalf, which is likely to have some benefits behind it. Therefore, many agents will objectively help customers buy shares of this company in order to obtain additional compensation from the entrusted company. These securities companies will charge fees when investing for their clients. The agent is paid, but the bonus is related to the business. Some investors will privately agree that the agent will take the commission from the investment profit, but these actions violate the industry standards.
