FINANCIAL MARKETS

In economics, a financial market is a mechanism that allows people to easily buy and sell (trade) financial securities (such as stocks and bonds), commodities (such as precious metals or agricultural goods), and other fungible items of value at low transaction costs and at prices that reflect the efficient-market hypothesis.

Financial markets have evolved significantly over several hundred years and are undergoing constant innovation to improve liquidity.
Both general markets (where many commodities are traded) and specialized markets (where only one commodity is traded) exist. Markets work by placing many interested buyers and sellers in one "place", thus making it easier for them to find each other. An economy which relies primarily on interactions between buyers and sellers to allocate resources is known as a market economy in contrast either to a command economy or to a non-market economy such as a gift economy.

In finance, financial markets facilitate:

1)The raising of capital (in the capital markets)
2)The transfer of risk (in the derivatives markets)
3)International trade (in the currency markets)
and are used to match those who want capital to those who have it.Typically a borrower issues a receipt to the lender promising to pay back the capital. These receipts are securities which may be freely bought or sold. In return for lending money to the borrower, the lender will expect some compensation in the form of interest or dividends.In mathematical finance, the concept of a financial market is defined in terms of a continuous-time Brownian motion stochastic process.

1)Definition:

In economics, typically, the term market means the aggregate of possible buyers and sellers of a thing 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) 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.

Financial markets can be domestic or they can be international. Types of financial markets The financial markets can be divided into different subtypes:

2)Capital markets which 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.
Futures markets, which provide standardized forward contracts for trading products at some future date; see also forward market.
Insurance markets, which facilitate the redistribution of various risks.
Foreign exchange markets, which facilitate the trading of foreign exchange.
The capital markets consist of primary markets and secondary markets. Newly formed (issued) securities are bought or sold in primary markets. Secondary markets allow investors to sell securities that they hold or buy existing securities.

3)Raising capital:

To understand financial markets, let us look at what they are used for, i.e. what is their purpose? Without financial markets, borrowers would have difficulty finding lenders themselves. Intermediaries such as banks 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.

LENDERS
3.1.1)Individuals : Many individuals are not aware that they arelenders, 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; or
.invests in company shares

3.1.2)Companies: Companies tend to be borrowers 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. There are a few companies that have very strong cash flows. These companies tend to be lenders rather than borrowers. Such companies may decide to return cash to lenders (e.g. via a share buyback.) Alternatively, they may seek to make more money on their cash by lending it (e.g. investing in bonds and stocks.)

3.2)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 modernisation 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 nationalised 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 nationalised 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.


4)Derivative products:

During the 1980s and 1990s, a major growth sector in financial markets is 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. It is also called financial economics

UPSIDE, DOWNSIDE: UNDERSTANDING RISK :

Risk is part of investing and understanding what it is and how it is measured is essential to developing an investment philosophy. In this chapter, we will lay the foundations for analyzing risk in investments. We present alternative models for measuring risk and converting these risk measures into an expected return. We will also consider ways in an investor can measure his or her risk aversion.We begin with a discussion of risk and present our analysis in three steps. In the first step,we define risk in terms of uncertainty about future returns. The greater this uncertainty, the more risky an investment is perceived to be. The next step, which we believe is the central one, is to decompose this risk into risk that can be diversified away by investors and risk that cannot. In the third step, we look at how different risk and return models in finance attempt to measure this non-diversifiable risk. We compare and contrast the most widely used model, the capital asset pricing model, with other models, and explain how and why they diverge in their measures of risk and the implications for the equity risk premium. In the second part of this chapter, we consider default risk and how it is measured by ratings agencies. In addition, we discuss the determinants of the default spread and why it might change over time.
What is risk? Risk, for most of us, refers to the likelihood that in life’s games of chance, we will receive an outcome that we will not like. For instance, the risk of driving a car too fast is getting a speeding ticket, or worse still, getting into an accident. Webster’s dictionary, in fact, defines risk as “exposing to danger or hazard”. Thus, risk is perceived almost entirely in negative terms.
In finance, our definition of risk is both different and broader. Risk, as we see it, refers to the likelihood that we will receive a return on an investment that is different from the return we expected to make. Thus, risk includes not only the bad outcomes, i.e, returns that are lower than expected, but also good outcomes, i.e., returns that are higher than expected. In fact, we can refer to the former as downside risk and the latter is upside risk;but we consider both when measuring risk.

The first symbol is the symbol for “danger”, while the second is the symbol for
“opportunity”, making risk a mix of danger and opportunity. It illustrates very clearly the tradeoff that every investor and business has to make – between the higher rewards that come with the opportunity and the higher risk that has to be borne as a consequence of the danger.Much of this chapter can be viewed as an attempt to come up with a model that best measures the “danger” in any investment and then attempts to convert this into the “opportunity” that we would need to compensate for the danger. In financial terms, we term the danger to be “risk” and the opportunity to be “expected return”.

Equity Risk and Expected Return To demonstrate how risk is viewed in finance, we will present risk analysis in three steps. First, we will define risk . Second, we will differentiate between risk that is specific to one or a few investments and risk that affects a much wider cross section of investments.We will argue that in a market where investors are well diversified, it is only the latter risk,called market risk that will be rewarded. Third, we will look at alternative models for
measuring this market risk and the expected returns that go with it.

Defining Risk

Investors who buy assets expect to earn returns over the time horizon that they hold the asset. Their actual returns over this holding period may be very different from the expected returns and it is this difference between actual and expected returns that is source of risk. For example, assume that you are an investor with a 1-year time horizon buying a 1- year Treasury bill (or any other default-free one-year bond) with a 5% expected return. At the end of the 1-year holding period, the actual return on this investment will be 5%, which is equal to the expected return.
