Finance

Finance is the science of funds management. The general areas of finance are business finance,personal finance, and public finance. Finance includes saving money and often includes lending money. The field of finance deals with the concepts of time, money, risk and how they are interrelated. It also deals with how money is spent and budgeted.

One facet of finance is through individuals and business organizations, which deposit money in a bank. The bank then lends the money out to other individuals or corporations for consumption or investment and charges interest on the loans.

Loans have become increasingly packaged for resale, meaning that an investor buys the loan (debt) from a bank or directly from a corporation. Bonds are debt instruments sold to investors for organizations such as companies, governments or charities. The investor can then hold the debt and collect the interest or sell the debt on a secondary market. Banks are the main facilitators of funding through the provision of credit, although private equity, mutual funds, hedge funds, and other organizations have become important as they invest in various forms of debt. Financial assets, known as investments, are financially managed with careful attention to financial risk management to control financial risk. Financial instruments allow many forms of securitized assets to be traded on securities exchangessuch as stock exchanges, including debt such as bonds as well as equity in publicly traded corporations.

Central banks, such as the Federal Reserve System banks in the United States and Bank of England in the United Kingdom, are strong players in public finance, acting as lenders of last resort as well as strong influences on monetary and credit conditions in the economy

Stock market

A stock market or equity market is a public (a loose network of economic transactions, not a physical facility or discrete) entity for the trading of company stock (shares) and derivatives at an agreed price; these aresecurities listed on a stock exchange as well as those only traded privately.

The size of the world stock market was estimated at about $36.6 trillion at the start of October 2008.^[1] Thetotal world derivatives market has been estimated at about $791 trillion face or nominal value,^[2] 11 times the size of the entire world economy.^[3] The value of the derivatives market, because it is stated in terms of notional values, cannot be directly compared to a stock or a fixed income security, which traditionally refers to an actual value. Moreover, the vast majority of derivatives 'cancel' each other out (i.e., a derivative 'bet' on an event occurring is offset by a comparable derivative 'bet' on the event not occurring). Many such relatively illiquid securities are valued as marked to model, rather than an actual market price.

The stocks are listed and traded on stock exchanges which are entities of a corporation or mutual organizationspecialized in the business of bringing buyers and sellers of the organizations to a listing of stocks and securities together. The largest stock market in the United States, by market cap, is the New York Stock Exchange, NYSE. In Canada, the largest stock market is the Toronto Stock Exchange. Major European examples of stock exchanges include the London Stock Exchange, Paris Bourse, and the Deutsche Börse(Frankfurt Stock Exchange). Asian examples include the Tokyo Stock Exchange, the Hong Kong Stock Exchange, the Shanghai Stock Exchange, and the Bombay Stock Exchange. In Latin America, there are such exchanges as the BM&F Bovespa and the BMV.
