Stock exchange

A stock exchange, share market or bourse is a corporation or mutual organization which provides "trading" facilities for stock brokers and traders, to trade stocks and other securities. Stock exchanges also provide facilities for the issue and redemption of securities as well as other financial instruments and capital events including the payment of income and dividends. The securities traded on a stock exchange include: shares issued by companies, unit trusts and other pooled investment products and bonds. To be able to trade a security on a certain stock exchange, it has to be "listed" there. Usually there is a central location at least for recordkeeping, but trade is less and less linked to such a physical place, as modern markets are electronic networks, which gives them advantages of speed and cost of transactions. Trade on an exchange is by members only. The initial offering of stocksand bonds to investors is by definition done in the primary market and subsequent trading is done in the secondary market. A stock exchange is often the most important component of a stock market. Supply and demand in stock markets is driven by various factors which, as in all free markets, affect the price of stocks (see stock valuation).

There is usually no compulsion to issue stock via the stock exchange itself, nor must stock be subsequently traded on the exchange. Such trading is said to be "off exchange" or over-the-counter. This is the usual way that bonds are traded. Increasingly, stock exchanges are part of a global market for securities.

History of stock exchanges

In 11th century France the "courtiers de change" were concerned with managing and regulating the debts of agricultural communities on behalf of the banks. As these men also traded in debts, they could be called the first brokers.

Some stories suggest that the origins of the term "bourse" come from the Latin "bursa" meaning "a bag" because, in 13th century Bruges, the sign of a purse (or perhaps three purses), hung on the front of the house where merchants met.

.

In the middle of the 13th century, Venetian bankers began to trade in government securities. In 1351, the Venetian Government outlawed spreading rumors intended to lower the price of government funds. There were people in Pisa, Verona, Genoa and Florence who also began trading in government securities during the 14th century. This was only possible because these were independent city states ruled by a council of influential citizens, not by a duke.

The Dutch later started joint stock companies, which let shareholders invest in business ventures and get a share of their profits - or losses. In 1602, the Dutch East India Company issued the first shares on the Amsterdam Stock Exchange. It was the first company to issue stocks and bonds. In 1688, the trading of stocks began on a stock exchange in London.

The role of stock exchanges

Stock exchanges have multiple roles in the economy, this may include the following: [cite journal |last=Diamond |first=Peter A. |authorlink= |coauthors= |year=1967 |month= |title=The Role of a Stock Market in a General Equilibrium Model with Technological Uncertainty |journal=American Economic Review |volume=57 |issue=4 |pages=759–776 |doi= |url=http://www.jstor.org/pss/1815367 |accessdate= |quote= ]

Raising capital for businesses

The Stock Exchange provides companies with the facility to raise capital for expansion through selling shares to the investing public. [cite journal |last=Gilson |first=Ronald J. |authorlink= |coauthors=Black, Bernard S. |year=1998 |month= |title=Venture Capital and the Structure of Capital Markets: Banks Versus Stock Markets |journal=Journal of Financial Economics |volume=47 |issue= |pages=243–277 |doi=10.2139/ssrn.46909 |url= |accessdate= |quote= ]

Mobilizing savings for investment

When people draw their savings and invest in shares, it leads to a more rational allocation of resources because funds, which could have been consumed, or kept in idle deposits with banks, are mobilized and redirected to promote business activity with benefits for several economic sectors such as agriculture, commerce and industry, resulting in a stronger economic growth and higher productivity levels and firms.

Facilitating company growth

Companies view acquisitions as an opportunity to expand product lines, increase distribution channels, hedge against volatility, increase its market share, or acquire other necessary business assets. A takeover bid or a merger agreement through the stock market is one of the simplest and most common ways for a company to grow by acquisition or fusion.

Redistribution of wealth

Stocks exchanges do not exist to redistribute wealth. However, both casual and professional stock investors, through dividends and stock price increases that may result in capital gains, will share in the wealth of profitable businesses.

Corporate governance

By having a wide and varied scope of owners, companies generally tend to improve on their management standards and efficiency in order to satisfy the demands of these shareholders and the more stringent rules for public corporations imposed by public stock exchanges and the government. Consequently, it is alleged that public companies (companies that are owned by shareholders who are members of the general public and trade shares on public exchanges) tend to have better management records than privately-held companies (those companies where shares are not publicly traded, often owned by the company founders and/or their families and heirs, or otherwise by a small group of investors). However, some well-documented cases are known where it is alleged that there has been considerable slippage in corporate governance on the part of some public companies. The dot-com bubble in the early 2000s, and the subprime mortgage crisis in 2007-08, are classical examples of corporate mismanagement. Companies like Pets.com (2000), Enron Corporation (2001), One.Tel (2001), Sunbeam (2001), Webvan (2001), Adelphia (2002), MCI WorldCom (2002), Parmalat (2003), Fannie Mae (2008), Freddie Mac (2008), Lehman Brothers (2008), were among the most widely scrutinized by the media.

Creating investment opportunities for small investors

As opposed to other businesses that require huge capital outlay, investing in shares is open to both the large and small stock investors because a person buys the number of shares they can afford. Therefore the Stock Exchange provides the opportunity for small investors to own shares of the same companies as large investors.

Government capital-raising for development projects

Governments at various levels may decide to borrow money in order to finance infrastructure projects such as sewage and water treatment works or housing estates by selling another category of securities known as bonds. These bonds can be raised through the Stock Exchange whereby members of the public buy them, thus loaning money to the government. The issuance of such bonds can obviate the need to directly tax the citizens in order to finance development, although by securing such bonds with the full faith and credit of the government instead of with collateral, the result is that the government must tax the citizens or otherwise raise additional funds to make any regular coupon payments and refund the principal when the bonds mature.

Barometer of the economy

At the stock exchange, share prices rise and fall depending, largely, on market forces. Share prices tend to rise or remain stable when companies and the economy in general show signs of stability and growth. An economic recession, depression, or financial crisis could eventually lead to a stock market crash. Therefore the movement of share prices and in general of the stock indexes can be an indicator of the general trend in the economy.

Listing requirements

Listing requirements are the set of conditions imposed by a given stock exchange upon companies that want to be listed on that exchange. Such conditions sometimes include minimum number of shares outstanding, minimum market capitalization, and minimum annual income.

Requirements by stock exchange

Companies have to meet the requirements of the exchange in order to have their stocks and shares listed and traded there, but requirements vary by stock exchange:

*London Stock Exchange: The main market of the London Stock Exchange has requirements for a minimum market capitalization (£700,000), three years of audited financial statements, minimum public float (25 per cent) and sufficient working capital for at least 12 months from the date of listing.

*NASDAQ Stock Exchange: To be listed on the NASDAQ a company must have issued at least 1.25 million shares of stock worth at least $70 million and must have earned more than $11 million over the last three years. [ [http://www.nasdaq.com/about/listing_information.stm NASDAQ Corporate -NASDAQ Listing Information ] ]

*New York Stock Exchange: To be listed on the New York Stock Exchange (NYSE), for example, a company must have issued at least a million shares of stock worth $100 million and must have earned more than $10 million over the last three years. [http://www.nyse.com/Frameset.html?displayPage=/listed/1022540125610.html]

*Bombay Stock Exchange: Bombay Stock Exchange (BSE) has requirements for a minimum market capitalization of Rs.250 Million and minimum public float equivalent to Rs.100 Million. [ [http://www.bseindia.com/about/abintrobse/listsec.asp About Us ] ]

Ownership

Stock exchanges originated as mutual organizations, owned by its member stock brokers. There has been a recent trend for stock exchanges to "demutualize", where the members sell their shares in an initial public offering. In this way the mutual organization becomes a corporation, with shares that are listed on a stock exchange. Examples are Australian Securities Exchange (1998), Euronext (merged with New York Stock Exchange), NASDAQ (2002), the New York Stock Exchange (2005), Bolsas y Mercados Españoles, and the São Paulo Stock Exchange (2007).

Other types of exchanges

In the 19th century, exchanges were opened to trade forward contracts on commodities. Exchange traded forward contracts are called futures contracts. These "commodity exchanges" later started offering future contracts on other products, such as interest rates and shares, as well as options contracts. They are now generally known as futures exchanges.

The future of stock exchanges

The future of stock trading appears to be electronic, as competition is continually growing between the remaining traditional New York Stock Exchange specialist system against the relatively new, all Electronic Communications Networks, or "ECN"s. ECNs point to their speedy execution of large block trades, while specialist system proponents cite the role of specialists in maintaining orderly markets, especially under extraordinary conditions or for special types of orders.

The ECNs contend that an array of special interests profit at the expense of investors in even the most mundane exchange-directed trades. Machine-based systems, they argue, are much more efficient, because they speed up the execution mechanism and eliminate the need to deal with an intermediary.

Historically, the 'market' (which, as noted, encompasses the totality of stock trading on all exchanges) has been slow to respond to technological innovation. Conversion to all-electronic trading could erode/eliminate the trading profits of floor specialists and the NYSE's "upstairs traders."

William Lupien, founder of the Instinet trading system and the OptiMark system, has been quoted as saying "I'd definitely say the ECNs are winning... Things happen awfully fast once you reach the tipping point. We're now at the tipping point."

One example of improved efficiency of ECNs is the prevention of front running, by which manual Wall Street traders use knowledge of a customer's incoming order to place their own orders so as to benefit from the perceived change to market direction that the introduction of a large order will cause. By executing large trades at lightning speed without manual intervention, ECNs make impossible this illegal practice, for which several NYSE floor brokers were investigated and severely fined in recent years. [ [http://www.nypost.com/seven/09212006/business/nyse_specialist_faces_27_months_for_trades_business_paul_tharp.htm NYSE SPECIALIST FACES 27 MONTHS FOR TRADES ] ] Under the specialist system, when the market sees a large trade in a name, other buyers are immediately able to look to see how big the trader is in the name, and make inferences about why s/he is selling or buying. All traders who are quick enough are able to use that information to anticipate price movements.

ECNs have changed ordinary stock transaction processing (like brokerage services before them) into a commodity-type business. ECNs could regulate the fairness of initial public offerings (IPOs), oversee Hambrecht's OpenIPO process, or measure the effectiveness of securities research and use transaction fees to subsidize small- and mid-cap research efforts.

SomeWho|date=July 2007, however, believe the answer will be some combination of the best of technology and "upstairs trading" — in other words, a hybrid model.

Trading 25,000 shares of General Electric stock (recentwhen quote: $34.76; recentwhen volume: 44,760,300) would be a relatively simple e-commerce transaction; trading 100 shares of Berkshire Hathaway Class A stock (recent quote: $139,700.00; recent volume: 850) may never be. The choice of system should be clear (but always that of the trader), based on the characteristics of the security to be traded.

Even with ECNs forming an important part of a national market system, opportunities presumably remain to profit from the spread between the bid and offer price. That is especially true for investment managers that direct huge trading volume, and own a stake in an ECN or specialist firm. For example, in its individual stock-brokerage accounts, "Fidelity Investments runs 29% of its undesignated orders in NYSE-listed stocks, and 37% of its undesignated market orders through the Boston Stock Exchange, where an affiliate controls a specialist post."
