Cooperative thrift is not a source of finance to a Joint Stock Company. Cooperative thrift is a savings scheme where members pool their resources to create a common fund that can be loaned out to members at a low interest rate. While cooperative thrift can be a source of finance for individuals or small businesses, it is not a formal source of finance for a Joint Stock Company. On the other hand, bank loans, equity shares, debentures, and preference shares are all common sources of finance for a Joint Stock Company. Bank loans provide short-term or long-term financing to companies, while equity shares, debentures, and preference shares are types of securities that can be issued by companies to raise funds from investors.
