Financial market

A financial market is a market in which people trade financial securities, commodities, and other fungible items of value at low transaction costs and at prices that reflect supply and demand. Securities include stocks and bonds, and commodities include precious metals or agricultural products.

In economics, typically, the term market means the aggregate of possible buyers and sellers of a certain good or service and the transactions between them.

The term "market" is sometimes used for what are more strictly exchanges, organizations that facilitate the trade in financial securities, e.g., a stock exchange or commodity exchange. This may be a physical location (like the NYSE, BSE, NSE) or an electronic system (like NASDAQ). Much trading of stocks takes place on an exchange; still, corporate actions (merger, spinoff) are outside an exchange, while any two companies or people, for whatever reason, may agree to sell stock from the one to the other without using an exchange.

Trading of currencies and bonds is largely on a bilateral basis, although some bonds trade on a stock exchange, and people are building electronic systems for these as well, similar to stock exchanges.

Types of financial markets

Within the financial sector, the term "financial markets" is often used to refer just to the markets that are used to raise finance: for long term finance, the Capital markets; for short term finance, the Money markets. Another common use of the term is as a catchall for all the markets in the financial sector, as per examples in the breakdown below.

Capital markets which to consist of:
- Stock markets, which provide financing through the issuance of shares or common stock, and enable the subsequent trading thereof.
- Bond markets, which provide financing through the issuance of bonds, and enable the subsequent trading thereof.
Commodity markets, which facilitate the trading of commodities.
Money markets, which provide short term debt financing and investment.
Derivatives markets, which provide instruments for the management of financial risk.^[1]
Futures markets, which provide standardized forward contracts for trading products at some future date; see also forward market.
Foreign exchange markets, which facilitate the trading of foreign exchange.

The capital markets may also be divided into primary markets and secondary markets. Newly formed (issued) securities are bought or sold in primary markets, such as during initial public offerings. Secondary markets allow investors to buy and sell existing securities. The transactions in primary markets exist between issuers and investors, while secondary market transactions exist among investors.

Liquidity is a crucial aspect of securities that are traded in secondary markets. Liquidity refers to the ease with which a security can be sold without a loss of value. Securities with an active secondary market mean that there are many buyers and sellers at a given point in time. Investors benefit from liquid securities because they can sell their assets whenever they want; an illiquid security may force the seller to get rid of their asset at a large discount.

Raising capital

Financial markets attract funds from investors and channel them to corporations—they thus allow corporations to finance their operations and achieve growth. Money markets allow firms to borrow funds on a short term basis, while capital markets allow corporations to gain long-term funding to support expansion (known as maturity transformation).

Without financial markets, borrowers would have difficulty finding lenders themselves. Intermediaries such as banks, Investment Banks, and Boutique Investment Banks can help in this process. Banks take deposits from those who have money to save. They can then lend money from this pool of deposited money to those who seek to borrow. Banks popularly lend money in the form of loans and mortgages.

More complex transactions than a simple bank deposit require markets where lenders and their agents can meet borrowers and their agents, and where existing borrowing or lending commitments can be sold on to other parties. A good example of a financial market is a stock exchange. A company can raise money by selling shares to investors and its existing shares can be bought or sold.

The following table illustrates where financial markets fit in the relationship between lenders and borrowers:

Relationship between lenders and borrowers
Lenders	Financial Intermediaries	Financial Markets	Borrowers
Individuals Companies	Banks Insurance Companies Pension Funds Mutual Funds	Interbank Stock Exchange Money Market Bond Market Foreign Exchange	Individuals Companies Central Government Municipalities Public Corporations

Lenders

The lender temporarily gives money to somebody else, on the condition of getting back the principal amount together with some interest/profit or charge.

Individuals & Doubles

Many individuals are not aware that they are lenders, but almost everybody does lend money in many ways. A person lends money when he or she:

Puts money in a savings account at a bank
Contributes to a pension plan
Pays premiums to an insurance company
Invests in government bonds

Companies

Companies tend to be lenders of capital. When companies have surplus cash that is not needed for a short period of time, they may seek to make money from their cash surplus by lending it via short term markets called money markets. Alternatively, such companies may decide to return the cash surplus to their shareholders (e.g. via a share repurchase or dividend payment).

Borrowers

Individuals borrow money via bankers' loans for short term needs or longer term mortgages to help finance a house purchase.
Companies borrow money to aid short term or long term cash flows. They also borrow to fund modernization or future business expansion.
Governments often find their spending requirements exceed their tax revenues. To make up this difference, they need to borrow. Governments also borrow on behalf of nationalized industries, municipalities, local authorities and other public sector bodies. In the UK, the total borrowing requirement is often referred to as the Public sector net cash requirement (PSNCR).

Governments borrow by issuing bonds. In the UK, the government also borrows from individuals by offering bank accounts and Premium Bonds. Government debt seems to be permanent. Indeed, the debt seemingly expands rather than being paid off. One strategy used by governments to reduce the value of the debt is to influence inflation.

Municipalities and local authorities may borrow in their own name as well as receiving funding from national governments. In the UK, this would cover an authority like Hampshire County Council.

Public Corporations typically include nationalized industries. These may include the postal services, railway companies and utility companies.

Many borrowers have difficulty raising money locally. They need to borrow internationally with the aid of Foreign exchange markets.

Borrowers having similar needs can form into a group of borrowers. They can also take an organizational form like Mutual Funds. They can provide mortgage on weight basis. The main advantage is that this lowers the cost of their borrowings.

Derivative products

During the 1980s and 1990s, a major growth sector in financial markets was the trade in so called derivative products, or derivatives for short.

In the financial markets, stock prices, bond prices, currency rates, interest rates and dividends go up and down, creating risk. Derivative products are financial products which are used to control risk or paradoxically exploit risk.^[2] It is also called financial economics.

Derivative products or instruments help the issuers to gain an unusual profit from issuing the instruments. For using the help of these products a contract has to be made. Derivative contracts are mainly 4 types:^[3]

Future
Forward
Option
Swap

Seemingly, the most obvious buyers and sellers of currency are importers and exporters of goods. While this may have been true in the distant past,^[when?] when international trade created the demand for currency markets, importers and exporters now represent only 1/32 of foreign exchange dealing, according to the Bank for International Settlements.^[4]

The picture of foreign currency transactions today shows:

Banks/Institutions
Speculators
Government spending (for example, military bases abroad)
Importers/Exporters
Tourists

Analysis of financial markets

See Statistical analysis of financial markets, statistical finance

Much effort has gone into the study of financial markets and how prices vary with time. Charles Dow, one of the founders of Dow Jones & Company and The Wall Street Journal, enunciated a set of ideas on the subject which are now called Dow theory. This is the basis of the so-called technical analysis method of attempting to predict future changes. One of the tenets of "technical analysis" is that market trends give an indication of the future, at least in the short term. The claims of the technical analysts are disputed by many academics, who claim that the evidence points rather to the random walk hypothesis, which states that the next change is not correlated to the last change. The role of human psychology in price variations also plays a significant factor. Large amounts of volatility often indicate the presence of strong emotional factors playing into the price. Fear can cause excessive drops in price and greed can create bubbles. In recent years the rise of algorithmic and high-frequency program trading has seen the adoption of momentum, ultra-short term moving average and other similar strategies which are based on technical as opposed to fundamental or theoretical concepts of market Behaviour.

The scale of changes in price over some unit of time is called the volatility. It was discovered by Benoît Mandelbrot that changes in prices do not follow a Gaussian distribution, but are rather modeled better by Lévy stable distributions. The scale of change, or volatility, depends on the length of the time unit to a power a bit more than 1/2. Large changes up or down are more likely than what one would calculate using a Gaussian distribution with an estimated standard deviation.
