Stock effects

Stock exchange or the stock market is a market related to the purchase and sale of securities or shares of the company and government bonds. The stock exchange, with money market is the main source of external financing for corporations and governments. Usually there is a central location, at least for the record, but the trade is now less and less linked to such a place, because the modern stock market today is the electronic network, which provides benefits in terms of speed and transaction costs. Trade in the stock can only be done by a member, the stockbroker. Supply and demand in stock markets supported the factors, just as in any free market, affecting the stock price (see the stock assessment).

A stock exchange is often the most important component of a stock market. There is no obligation to issue stock via the stock market itself and the shares have not traded at these exchanges: this sort of thing is called "off-exchange".

First offer of shares to investors called the prime market or the primary market and subsequent trading market called the second (secondary).
Conditions listing (listing share)

Companies must meet the requirements of a stock exchange so that their shares can be traded in dilist and there. For example, in order to be recorded in the NYSE (New York Stock Exchange), a company must have published at least 1 million shares at U.S. $ 100 million and must have earned more than U.S. $ 10 million in the last three years.
