The overall market is made up of millions of investors and traders , who may have differing ideas about the value of a specific stock and thus the price at which they are willing to buy or sell it.
A stock exchange provides a platform where such trading can be easily conducted by matching buyers and sellers of stocks. For the average person to get access to these exchanges, they would need a stockbroker.
This stockbroker acts as the middleman between the buyer and the seller. Getting a stockbroker is most commonly accomplished by creating an account with a well-established retail broker. The stock market also offers a fascinating example of the laws of supply and demand at work in real-time. For every stock transaction, there must be a buyer and a seller. Because of the immutable laws of supply and demand, if there are more buyers for a specific stock than there are sellers of it, the stock price will trend up.
Conversely, if there are more sellers of the stock than buyers, the price will trend down. The bid-ask or bid-offer spread the difference between the bid price for a stock and its ask or offer price represents the difference between the highest price that a buyer is willing to pay or bid for a stock and the lowest price at which a seller is offering the stock.
A trade transaction occurs either when a buyer accepts the ask price or a seller takes the bid price. If buyers outnumber sellers, they may be willing to raise their bids in order to acquire the stock. Sellers will, therefore, ask higher prices for it, ratcheting the price up. If sellers outnumber buyers, they may be willing to accept lower offers for the stock, while buyers will also lower their bids, effectively forcing the price down.
Some stock markets rely on professional traders to maintain continuous bids and offers since a motivated buyer or seller may not find each other at any given moment. These are known as specialists or market makers.
A two-sided market consists of the bid and the offer, and the spread is the difference in price between the bid and the offer. The more narrow the price spread and the larger size of the bids and offers the amount of shares on each side , the greater the liquidity of the stock.
Moreover, if there are many buyers and sellers at sequentially higher and lower prices, the market is said to have good depth. Matching buyers and sellers of stocks on an exchange was initially done manually, but it is now increasingly carried out through computerized trading systems. The manual method of trading was based on a system known as the open outcry system, where traders used verbal and hand signal communications to buy and sell large blocks of stocks in the trading pit or the exchange floor.
However, the open outcry system has been superseded by electronic trading systems at most exchanges. These systems can match buyers and sellers far more efficiently and rapidly than humans can, resulting in significant benefits such as lower trading costs and faster trade execution. High-quality stock markets tend to have small bid-ask spreads, high liquidity, and good depth, which means that individual stocks of high quality, large companies tend to have the same characteristics. Until recently, the ultimate goal for an entrepreneur was to get his or her company listed on a reputed stock exchange such as the NYSE or Nasdaq , because of the obvious benefits, which include:.
These benefits mean that most large companies are public rather than private. Very large private companies such as food and agriculture giant Cargill, industrial conglomerate Koch Industries, and DIY furniture retailer Ikea are among the world's most valuable private companies , and they are the exception rather than the norm.
But there are some drawbacks to being listed on a stock exchange, such as:. While this delayed listing may partly be attributable to the drawbacks listed above, the main reason could be that well-managed startups with a compelling business proposition have access to unprecedented amounts of capital from sovereign wealth funds , private equity, and venture capitalists. Such access to seemingly unlimited amounts of capital would make an IPO and exchange listing much less of a pressing issue for a startup.
The number of publicly-traded companies in the U. Numerous studies have shown that, over long periods of time, stocks generate investment returns that are superior to those from every other asset class. Stock returns arise from capital gains and dividends. A capital gain occurs when you sell a stock at a higher price than the price at which you purchased it.
A dividend is the share of profit that a company distributes to its shareholders. Dividends are an important component of stock returns. They have contributed nearly one-third of total equity return since , while capital gains have contributed two-thirds. Investors who want to swing for the fences with the stocks in their portfolios should have a higher tolerance for risk. These investors will be keen to generate most of their returns from capital gains rather than dividends.
On the other hand, investors who are conservative and need the income from their portfolios may opt for stocks that have a long history of paying substantial dividends. While stocks can be classified in a number of ways, two of the most common are by market capitalization and by sector. Market cap refers to the total market value of a company's outstanding shares and is calculated by multiplying these shares by the current market price of one share.
GICS is a four-tiered industry classification system that consists of 11 sectors and 24 industry groups. The 11 sectors are:. This sector classification makes it easy for investors to tailor their portfolios according to their risk tolerance and investment preference.
For example, conservative investors with income needs may weigh their portfolios toward sectors whose constituent stocks have better price stability and offer attractive dividends through so-called defensive sectors such as consumer staples, health care, and utilities. Aggressive investors may prefer more volatile sectors such as information technology, financials, and energy.
In addition to individual stocks, many investors are concerned with stock indices, which are also called indexes. Indices represent aggregated prices of a number of different stocks, and the movement of an index is the net effect of the movements of each individual component. Because of its weighting scheme and the fact that it only consists of 30 stocks when there are many thousands to choose from , it is not really a good indicator of how the stock market is doing.
Investors can trade indices indirectly via futures markets, or via exchange-traded funds ETFs , which act just like stocks on stock exchanges. A market index is a popular measure of stock market performance. Most market indices are market-cap weighted , which means that the weight of each index constituent is proportional to its market capitalization. Keep in mind, though, that a few of them are price-weighted , such as the DJIA. Stock exchanges have been around for more than two centuries.
The venerable NYSE traces its roots back to when two dozen brokers met in Lower Manhattan and signed an agreement to trade securities on commission. In , New York stockbrokers operating under the agreement made some key changes and reorganized as the New York Stock and Exchange Board.
The NYSE and Nasdaq are the two largest exchanges in the world, based on the total market capitalization of all the companies listed on the exchange. The number of U. The table below displays the 20 biggest exchanges globally, ranked by the total market capitalization of their listed companies. Source: World Federation of Exchanges.
Accessed Oct. Visual Capitalist. Securities and Exchange Commission. It is a significant occasion for a company in the journey of its growth and development. It enables a company to raise capital while strengthening its structure and reputation. It provides liquidity to investors and ensures effective monitoring of compliance of the issuer and trading of the securities in the interest of investors.
Going public is thereby a method of overcoming these constraints. By listing on a Stock Exchange, the company increases shareholder base and enhances credibility. Listing stimulates liquidity, giving shareholders the opportunity to realize the value of their investments. It allows shareholders to transact in the shares of the company, sharing risks as well as benefitting from any increase in the organizational value.
Going public increases visibility and improves public perception of the organization, thereby increasing employee value and morale. It may also lead to hiring of new staff and may facilitate stock-based payments such as ESOPs etc. The exchange maintains all such information and may support its processing to a certain extent. A stock market primarily serves the following main functions:.
Depending on the standard rules of demand and supply , the stock exchange needs to ensure that all interested market participants have instant access to data for all buy and sell orders thereby helping in the fair and transparent pricing of securities.
Additionally, it should also perform efficient matching of appropriate buy and sell orders. Stock markets need to support an efficient mechanism for price discovery, which refers to the act of deciding the proper price of a security and is usually performed by assessing market supply and demand and other factors associated with the transactions.
Say, a U. While getting the number of buyers and sellers for a particular financial security are out of control for the stock market, it needs to ensure that whosoever is qualified and willing to trade gets instant access to place orders which should get executed at a fair price.
While more participants are important for the efficient working of a market, the same market needs to ensure that all participants are verified and remain compliant with the necessary rules and regulations, leaving no room for default by any of the parties. Additionally, it should ensure that all associated entities operating in the market must also adhere to the rules, and work within the legal framework given by the regulator.
A marketplace is made by a variety of participants, which include market makers , investors, traders, speculators , and hedgers. All these participants operate in the stock market with different roles and functions. For instance, an investor may buy stocks and hold them for the long term spanning many years, while a trader may enter and exit a position within seconds.
A market maker provides necessary liquidity in the market, while a hedger may like to trade in derivatives for mitigating the risk involved in investments. The stock market should ensure that all such participants are able to operate seamlessly fulfilling their desired roles to ensure the market continues to operate efficiently.
Along with wealthy and institutional investors, a very large number of small investors are also served by the stock market for their small amount of investments. These investors may have limited financial knowledge, and may not be fully aware of the pitfalls of investing in stocks and other listed instruments. The stock exchange must implement necessary measures to offer the necessary protection to such investors to shield them from financial loss and ensure customer trust.
For instance, a stock exchange may categorize stocks in various segments depending on their risk profiles and allow limited or no trading by common investors in high-risk stocks. Exchanges often impose restrictions to prevent individuals with limited income and knowledge from getting into risky bets of derivatives.
Listed companies are largely regulated and their dealings are monitored by market regulators, like the Securities and Exchange Commission SEC of the U. Additionally, exchanges also mandate certain requirements — like, timely filing of quarterly financial reports and instant reporting of any relevant developments - to ensure all market participants become aware of corporate happenings. Failure to adhere to the regulations can lead to suspension of trading by the exchanges and other disciplinary measures.
A local financial regulator or competent monetary authority or institute is assigned the task of regulating the stock market of a country. The SEC is a federal agency that works independently of the government and political pressure. The mission of the SEC is stated as: "to protect investors, maintain fair, orderly, and efficient markets, and facilitate capital formation. Along with long-term investors and short-term traders, there are many different types of players associated with the stock market.
Each has a unique role, but many of the roles are intertwined and depend on each other to make the market run effectively. While individual stock exchanges compete against each other to get maximum transaction volume, stock markets as a whole may be facing competitive threats on two fronts. Dark pools , which are private exchanges or forums for securities trading and operate within private groups, are posing a challenge to public stock markets.
Though their legal validity is subject to local regulations, they are gaining popularity as participants save big on transaction fees. Amid the rising popularity of blockchains , many crypto exchanges have emerged.
Such exchanges are venues for trading cryptocurrencies and derivatives associated with that asset class. Though their popularity remains limited, they pose a threat to the traditional stock market model by automating a bulk of the work done by various stock market participants and by offering zero- to low-cost services.
The stock market is one of the most vital components of a free-market economy. It allows companies to raise money by offering stock shares and corporate bonds. It lets common investors participate in the financial achievements of the companies, make profits through capital gains , and earn money through dividends, although losses are also possible.
While institutional investors and professional money managers do enjoy some privileges owing to their deep pockets, better knowledge, and higher risk-taking abilities, the stock market attempts to offer a level playing field to common individuals. The stock market works as a platform through which savings and investments of individuals are efficiently channeled into productive investment opportunities. In the long term, this helps in capital formation and economic growth for the country. The first stock market in the world was the London stock exchange.
It was started in a coffeehouse, where traders used to meet to exchange shares, in The first stock exchange in the United States of America was started in Philadelphia in The Buttonwood Agreement, so named because it was signed under a buttonwood tree, marked the beginnings of New York's Wall Street in The agreement was signed by 24 traders and was the first American organization of its kind to trade in securities.
