A stock exchange serves as a platform for the buying and selling of stocks, bonds, and various securities. Beyond mere trading, these exchanges facilitate capital raising for companies, promote transparency among investors and firms, and educate the public about the significance of their investments.
Understanding the mechanisms of stock exchanges
When picturing a stock exchange, one might envision the bustling trading floor of the New York Stock Exchange (NYSE), where brokers actively engage in buying and selling stocks. This portrayal offers a glimpse into the fundamental workings of a stock exchange: a marketplace where buyers and sellers convene to exchange securities.
Traditionally, stock exchanges operated as physical locations—akin to the NYSE trading floor. However, the vast majority of exchanges now conduct all trading electronically. Participation in trading is restricted to brokers and dealers who meet stringent membership criteria set by the stock exchange.
Similarly, not every company is eligible to trade on a stock exchange. To gain "listing" status, a company must meet specific minimum requirements, such as SEC registration, a designated number of shareholders and shares outstanding, and various other qualifications. For instance, Nasdaq mandates that companies must soon have at least one female and one non-White or non-heterosexual individual on their board of directors.
In addition to facilitating securities transactions, stock exchanges offer vital services. They ensure liquidity by maintaining a constant flow of capital for buying and selling stocks, thereby fostering efficient operation of the broader stock market. Moreover, stock exchanges furnish real-time pricing data, empowering investors to make informed decisions regarding their investment portfolios.
Major participants in stock exchange
Stock markets can be intricate, necessitating various roles to enable securities trading. Here's a summary of the primary participants:
| Dealers | Firms or individuals trading securities for themselves, aiming to profit from price differentials. They buy stocks anticipating selling them at higher prices, boosting liquidity. |
| Brokers | Individuals or firms representing outside investors at stock exchanges. They act as agents, matching buyers and sellers, charging commissions for their services. Some are employed by exchanges to facilitate trading. |
| Broker-dealers | Firms combining brokerage and dealer roles. They execute trades for outside investors and engage in proprietary trading. |
| Market makers | Dealers enhancing exchange liquidity by buying and selling stocks for their own profit. Their activities promote efficient trading and orderly markets, with specialists, such as those on the NYSE, focusing on specific stocks. |
Stock exchanges and Initial Public Offerings (IPOs)
Stock exchanges facilitate the process of private companies raising significant capital through initial public offerings (IPOs). This transition renders the company publicly owned, with its shares listed for trading on an exchange.
While the debut of a new public company can generate considerable buzz, investors should exercise caution. Newly public firms frequently encounter challenges in sustaining growth, and some may even face closure. Hence, recent IPOs carry notable investment risks.
Primary stock exchanges
While there are over 60 significant stock exchanges globally, the bulk of trading activity occurs on a select few, notably:
New York Stock Exchange (NYSE)
As the world's largest stock exchange, NYSE hosts trading for major corporations like Amazon and Apple. It operates as an auction-based market, with electronic trading dominating, although physical trading has been halted due to the Covid-19 pandemic.
Nasdaq
Ranked as the second-largest exchange globally, Nasdaq operates on a dealer market system. It pioneered electronic trading and is favored by many major tech firms due to its easier process for public listing.
London Stock Exchange (LSE)
The largest exchange in Europe, LSE sees participation from thousands of companies worldwide. It maintains a physical trading floor in London.
Shanghai stock exchange
China's largest exchange, Shanghai Stock Exchange trades two types of company stocks: A-shares and B-shares. While B-shares are open to foreign investment and quoted in USD, A-shares are quoted in yuan and accessible to foreign investors only under specific conditions.
Varieties of stock exchanges
Auction markets
In auction markets, security prices are determined by the highest bid price from buyers and the lowest offer price from sellers. Broker-dealers execute trades for clients or themselves, acting as dealers.
Dealer markets
Dealers in dealer markets quote prices at which they're willing to buy or sell specific stocks. They facilitate transactions using their own capital, enhancing market liquidity.
Electronic exchanges
Electronic exchanges leverage technology to connect buyers and sellers virtually, replacing traditional trading floors. Most exchanges now support electronic trading, reducing reliance on in-person trading.
Over-the-Counter (OTC) exchanges
OTC exchanges facilitate trading outside major stock exchanges, often through broker-dealer networks. They cater to smaller companies or securities that don't meet listing requirements of major exchanges, including penny stocks and bonds.
Purchasing stocks on a stock exchange
Opening an online brokerage account enables you to initiate transactions in securities listed on major stock exchanges. If seeking personalized guidance, opt for a financial advisor or full-service brokerage firm as your stock broker.
Regardless of your choice, your broker will relay buy and sell orders to broker-dealers operating on stock exchanges, striving to match your specified price. However, order fulfillment time varies depending on market liquidity.
For those uncertain about stock or exchange selection, investing through a robo-advisor is an option. Robo-advisors customize investment strategies based on financial goals and risk tolerance, automating the process.
