Before moving ahead with the name, let’s first understand what financial intermediaries are. Financial intermediaries are the middlemen in a financial transaction between two parties. Here’s a list of key intermediary players in the US stock market:
Broker-dealers
As the name suggests, broker-dealers play a dual role in the stock market by selling and purchasing securities while also distributing other investment products. In simple words, the role of B-Ds in the US market is to either sell/purchase securities on their account as dealers or sell/purchase securities on account of others as brokers.
In the US, there are over 3,298 B-Ds, including big names like Edward Jones and Charles Schwab.
Clearing agencies
A clearing agency is a person or firm primarily responsible for ensuring the delivery of transactions. These agencies confirm and settle all kinds of financial transactions in the stock market.
Under Section 3(a) 23(A) of the Securities and Exchange Act, clearing agencies have been defined. There are two types of clearing agencies: Clearing Corporations and Depository. The former deals with confirming and settling financial transactions, and the latter takes up the role of safely and electronically holding records.
Investment banks
Investment banks play a major role in the US stock market. Their working portfolio is diverse as it includes looking into mergers and acquisitions, underwriting new stocks/IPOs, and assuming the role of financial advisor to the public and government. Names like Goldman Sachs, JP Morgan Chase & Co., and UBS are leading investment banks in the US.
ECNs/ATSs
Alternative trading systems are the backbone of large purchases and sales in the stock market as they work to seamlessly match buy and sell orders. Now, an electronic communication network is possibly the most widely used type of ATS. It is a computer system that helps automate the matching of purchase and sale orders.
Note: A person can not place an order with ECNs directly. They need to have a broker account.
Securities exchange
A securities exchange is like the actual playing field for investors where the buying and selling of securities of the stock market takes place. There is a long list of securities exchanges in the US, including the New York Stock Exchange (NYSE), the American Stock Exchange (AMEX), and the National Association of Securities Dealers Automated Quotation System (Nasdaq).
Any company that wishes to list its shares can do so in one of the securities exchanges registered with the SEC. It is only through these securities exchanges that investors can buy or sell stocks.
