A stock exchange, (formerly a securities exchange) 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, derivatives, 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 stocks and 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 derivatives and bonds are traded. Increasingly, stock exchanges are part of a global market for securities.

A floating exchange rate or a flexible exchange rate is a type of exchange rate regime wherein a currency's value is allowed to fluctuate according to the foreign exchange market. A currency that uses a floating exchange rate is known as a floating currency. The opposite of a floating exchange rate is a fixed exchange rate.

There are economists who think that, in most circumstances, floating exchange rates are preferable to fixed exchange rates. As floating exchange rates automatically adjust, they enable a country to dampen the impact of shocks and foreign business cycles, and to preempt the possibility of having a balance of payments crisis. However, in certain situations, fixed exchange rates may be preferable for their greater stability and certainty. This may not necessarily be true, considering the results of countries that attempt to keep the prices of their currency "strong" or "high" relative to others, such as the UK or the Southeast Asia countries before the Asian currency crisis. The debate of making a choice between fixed and floating exchange rate regimes is set forth by Mundell-Fleming model, which argues that an economy cannot simultaneously maintain a fixed exchange rate, free capital movement, and an independent monetary policy. It can choose any two for control, and leave third to the market forces.

In cases of extreme appreciation or depreciation, a central bank will normally intervene to stabilize the currency. Thus, the exchange rate regimes of floating currencies may more technically be known as a managed float. A central bank might, for instance, allow a currency price to float freely between an upper and lower bound, a price "ceiling" and "floor". Management by the central bank may take the form of buying or selling large lots in order to provide price support or resistance, or, in the case of some national currencies, there may be legal penalties for trading outside these bounds.
