Established in 1875, the Bombay Stock Exchange is Asia's first stock exchange.

In 12th century France the courratiers de change were concerned with managing and regulating the debts of agricultural communities on behalf of the banks. Because these men also traded with debts, they could be called the first brokers. A common misbelief is that in late 13th century Bruges commodity traders gathered inside the house of a man called Van der Beurze, and in 1309 they became the "Brugse Beurse", institutionalizing what had been, until then, an informal meeting, but actually, the family Van der Beurze had a building in Antwerp where those gatherings occurred;[6] the Van der Beurze had Antwerp, as most of the merchants of that period, as their primary place for trading. The idea quickly spread around Flanders and neighboring counties and "Beurzen" soon opened in Ghentand Amsterdam.

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. Bankers in Pisa, Verona, Genoa and Florence also began trading in government securities during the 14th century. This was only possible because these were independent city states not ruled by a duke but a council of influential citizens. 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 share on theAmsterdam Stock Exchange. It was the first company to issue stocks and bonds.

The Amsterdam Stock Exchange (or Amsterdam Beurs) is also said to have been the first stock exchange to introduce continuous trade in the early 17th century. The Dutch "pioneered short selling, option trading, debt-equity swaps, merchant banking, unit trusts and other speculative instruments, much as we know them".[7]There are now stock markets in virtually every developed and most developing economies, with the world's biggest markets being in the United States, United Kingdom, Japan, India, China, Canada, Germany, France, South Korea and the Netherlands.[8]

[edit]Importance of stock market

Market participants

A few decades ago, worldwide, buyers and sellers were individual investors, such as wealthy businessmen, with long family histories (and emotional ties) to particular corporations. Over time, markets have become more "institutionalized"; buyers and sellers are largely institutions (e.g., pension funds, insurance companies, mutual funds, index funds, exchange-traded funds, hedge funds, investor groups, banksand various other financial institutions). The rise of the institutional investor has brought with it some improvements in market operations. Thus, the government was responsible for "fixed" (and exorbitant) fees being markedly reduced for the 'small' investor, but only after the large institutions had managed to break the brokers' solid front on fees. (They then went to 'negotiated' fees, but only for large institutions.[citation needed])

However, corporate governance (at least in the West) has been very much adversely affected by the rise of (largely 'absentee') institutional 'owners'.[citation needed]

Stock market

Participants in the stock market range from small individual stock investors to large hedge fund traders, who can be based anywhere. Their orders usually end up with a professional at a stock exchange, who executes the order.

Some exchanges are physical locations where transactions are carried out on a trading floor, by a method known as open outcry. This type of auction is used in stock exchanges and commodity exchanges where traders may enter "verbal" bids and offers simultaneously. The other type of stock exchange is a virtual kind, composed of a network of computers where trades are made electronically via traders.

Actual trades are based on an auction market model where a potential buyer bids a specific price for a stock and a potential sellerasks a specific price for the stock. (Buying or selling at market means you will accept any ask price or bid price for the stock, respectively.) When the bid and ask prices match, a sale takes place, on a first-come-first-served basis if there are multiple bidders or askers at a given price.

The purpose of a stock exchange is to facilitate the exchange of securities between buyers and sellers, thus providing a marketplace(virtual or real). The exchanges provide real-time trading information on the listed securities, facilitating price discovery.

The New York Stock Exchange is a physical exchange, also referred to as a listed exchange — only stocks listed with the exchange may be traded. Orders enter by way of exchange members and flow down to a floor broker, who goes to the floor trading post specialist for that stock to trade the order. The specialist's job is to match buy and sell orders using open outcry. If a spread exists, no trade immediately takes place--in this case the specialist should use his/her own resources (money or stock) to close the difference after his/her judged time. Once a trade has been made the details are reported on the "tape" and sent back to the brokerage firm, which then notifies the investor who placed the order. Although there is a significant amount of human contact in this process, computers play an important role, especially for so-called "program trading".

The NASDAQ is a virtual listed exchange, where all of the trading is done over a computer network. The process is similar to the New York Stock Exchange. However, buyers and sellers are electronically matched. One or more NASDAQ market makers will always provide a bid and ask price at which they will always purchase or sell 'their' stock.[4]

The Paris Bourse, now part of Euronext, is an order-driven, electronic stock exchange. It was automated in the late 1980s. Prior to the 1980s, it consisted of an open outcry exchange. Stockbrokers met on the trading floor or the Palais Brongniart. In 1986, the CATS trading system was introduced, and the order matching process was fully automated.

From time to time, active trading (especially in large blocks of securities) have moved away from the 'active' exchanges. Securities firms, led by UBS AG, Goldman Sachs Group Inc. and Credit Suisse Group, already steer 12 percent of U.S. security trades away from the exchanges to their internal systems. That share probably will increase to 18 percent by 2010 as more investment banks bypass the NYSE and NASDAQ and pair buyers and sellers of securities themselves, according to data compiled by Boston-based Aite Group LLC, a brokerage-industry consultant.[5]

Now that computers have eliminated the need for trading floors like the Big Board's, the balance of power in equity markets is shifting. By bringing more orders in-house, where clients can move big blocks of stock anonymously, brokers pay the exchanges less in fees and capture a bigger share of the $11 billion a year that institutional investors pay in trading commissions as well as the surplus of the century had taken place.[citation needed].

Information Memo 4

• The amendments redefine the term "day trading" to treat the sale of an existing position held
from the previous day as a liquidation, and the subsequent repurchase of that position as the
establishment of a new position not subject to day trading margin requirements.
• Day trading margin requirements – For day trades in equity securities, the day trading margin
requirement shall be 25 percent of either: (1) the cost of all day trades made during the day;
or (2) the highest open position during the day. If a customer's day-trading margin
requirement is to be calculated based on the highest open position during the day, the
customer's member organization must maintain adequate "time and tick" records
documenting the sequence in which each day trade is completed. "Time and tick"
information provided by the customer is not acceptable.
• Day trading buying power will be calculated based on the customer's account position as of
the close of business on the previous day. The amendments limit day trading buying power
to four times the day trader's maintenance margin excess. See Rule 431 (f)(8)(B)(iii).
• Day trading margin calls – A pattern day trader exceeding his day trading buying power
results in a special maintenance deficiency. Member organizations are required to issue a
day-trading margin call to cover the amount of the deficiency. Pattern day traders have five
business days to deposit funds to meet this day trading margin call. The day trading account
is restricted to day trading buying power of two times maintenance margin excess based on
the customer's daily total trading commitment, ["time and tick" can not be used during this
period] beginning on the trading day after the day trading buying power is exceeded until the
earlier of when the call is met or five business days. If the day trading margin call is not met
by the fifth business day, the account must be further restricted to trading only on a cash
available basis for 90 days or until the call is met. See Rule 431 (f)(8)(B)(iv)(2) & (3).
• Pattern day traders will be prohibited from utilizing cross guarantees to meet day trading
margin calls or to meet minimum equity requirements. See Rule 431 (f)(8)(B)(iv)(4).
• Deposits of funds to meet minimum equity requirements or to meet day trading margin calls
must remain in the customer's account and cannot be withdrawn for two business days. See
Rule 431 (f)(8)(B)(5).

Information Memo 3

The Securities and Exchange Commission (“SEC”) has approved amendments to Exchange Rule
431 (“Margin Requirements”) (see Exhibit A) establishing new requirements to address the
intraday risks associated with day trading in customer accounts.1 The amendments require that
equity and maintenance margin be deposited and maintained in customer accounts that engage in
a pattern of day trading in amounts sufficient to support the risks associated with such trading
activities. Margin requirements will be based on a day trader's activities during the day, rather
than on open securities positions at the end of the day. Additionally, the amendments prohibit
the use of cross guarantees and early withdrawal of account equity as these practices do not
require customers to demonstrate actual financial ability to engage in day trading. THE
The significant changes are summarized below:
• The term "pattern day-trader" is defined as any customer who executes four or more day
trades within five business days, provided the number of day-trades is more than 6% of the
total trades in the account during that period. See Rule 431 (f)(8)(B)(ii).
If the member organization knows, or has a reasonable basis to believe that a customer who
seeks to open an account, or seeks to resume day trading in an existing account will engage
in pattern day trading, then, the customer must immediately be considered a pattern day
trader in lieu of waiting five business days. See Rule 431 (f)(8)(B) Supplementary Material
• The minimum equity requirement for pattern day traders is $25,000. See Rule 431


Because Regulation T initial
margin requirements and NASD/
NYSE standard maintenance
margin requirements3 are calculated
only at the end of each day, a
day trader who has no positions in
his or her account at the end of the
day would not incur a Regulation
T initial margin nor a standard
maintenance margin requirement,
assuming no losses in the account
from that day’s trading. Current
NASD/NYSE initial margin provisions,
however, generally require
a customer to deposit margin of at
least $2,000, unless in excess of
the cost of the security.
Although the day trader may end
the day with no position, the day
trader’s clearing firm is at risk during
the day if credit is extended.
To address this risk, the NASD
and NYSE require day traders to
demonstrate that they have the
ability to meet the initial margin
requirements for at least their
largest open position during the
day. Specifically, under current
margin requirements, a customer
who meets the definition of day
trader under the rule must deposit
in his or her account the margin
that would have been required
under Regulation T (i.e., the 50
percent initial margin requirement)
if the customer had not liquidated
the position during the trading day.
If the customer day trades, but is
not considered a “day trader,” the
customer is still required to post 25
percent of the position held during
the day.4 Currently, this payment is
due after the risk has been incurred.
Therefore, the funds are not available
during the trading day when
the clearing firm is at risk.
Currently, if a customer’s day trading
results in a day-trading margin
call, the customer has seven days
to meet the call by depositing cash
or securities in the account.
Because day traders typically end
the day flat and this day-trading
“margin” deposit is not securing a
margin loan, the customer is not
required to leave the margin
deposit in the account and may
withdraw the deposit the day after
the deposit is made. If the customer
fails to meet a day-trading
margin call, no specific action to
the customer account is required
to be taken by the firm. There are
no securities to liquidate, as there
would be for an existing position,
because day traders typically end
the day flat.
