Final answer:
The subject is groups of investment bankers and underwriters that help issue and sell securities to the public during events like IPOs, playing a pivotal role in capital markets.
Step-by-step explanation:
The groups of investment bankers and brokerage divisions that work with an issuer to bring its securities to the market and sell them to the investing public are commonly known as underwriters or an underwriting syndicate. The process typically begins with an initial public offering (IPO), where a company sells its stock to the public for the first time, providing funds to repay early-stage investors such as angel investors and venture capital firms.
The role of these groups is vital in transforming financial flows by re-packaging money from suppliers of capital, such as banks and investors, to the seekers of capital, which include individual firms looking to expand and grow by selling stocks and issuing bonds.
