Investment
Investment or investing is a term with several closely-related meanings in business management, finance and economics, related to saving or deferring consumption. An asset is usually purchased, or equivalently a deposit is made in a bank, in hopes of getting a future return or interest from it.
Types of investment
The difference in the use of the term investment between the economics field and the finance field is that economists refer to a real investment (such as a machine or a house), while financial economists refer to a financial asset, such as money that is put into a bank or the market, which may then be used to buy a real asset.
Business Management
The investment decision (also known as capital budgeting) is one of the fundamental decisions of business management: managers determine the assets that the business enterprise obtains; these assets may be physical (e.g. buildings or machinery), intangible (e.g. patents, software, goodwill), or financial (see below). Whatever the type of asset, the manager must assess whether the net present value of the investment to the enterprise is positive; the net present value is calculated using the enterprise's marginal cost of capital.

Economics
· In Economics, investment means the purchase (and thus the production) and/or stock of capital goods and/or technology - goods which are not consumed but instead used in future production. Examples include building a railroad, or a factory, clearing land, or putting oneself through college. In measures of national income and output, investment is also a component of GDP given in the formula GDP = C + I + G + NX. The investment function in that aspect is divided into non-residential investment (such as factories, machinery etc) and residential investment (new houses).
· Investment is often modelled as a function of income and interest rates, given by the relation I = f(Y, r). An increase in income will encourage higher investment, whereas a higher interest rate may discourage investment as it becomes costlier to borrow money. Even if a firm chooses to use its own funds in an investment, the interest rate represents an opportunity cost of investing those funds rather than loaning them out for interest.
Finance
· In finance, investment means buying securities or other monetary or paper (financial) assets in the money markets or capital markets, or in fairly liquid real assets, such as gold as an investment, real estate, or collectibles. Valuation is the method for assessing whether a potential investment is worth its price.
· Types of financial investments include shares or other equity investment, and bonds (including bonds denominated in foreign currencies). These investments assets are then expected to provide income or positive future cash flows, but may increase or decrease in value giving the investor capital gains or losses.
· Trades in contingent claims or derivative securities do not necessarily have future positive expected cash flows - so are not considered to be assets, or strictly speaking, securities or investments. Nevertheless, since their cash flows are closely related to (or derived from) those of specific securities, they are often studied as or treated as investments.
· Investments are often made indirectly through intermediaries, such as banks, mutual funds, pension funds, insurance companies, collective investment schemes, or even investment clubs. Though their legal and procedural details differ, an intermediary generally makes an investment using money from many individuals, each of whom receives a claim on the intermediary.
Personal finance
· Within personal finance, money used to purchase shares, put in a collective investment scheme or used to buy any asset where there is an element of capital risk is deemed an investment. Saving within personal finance refers to money put aside, normally on a regular basis. This distinction is important as investment risk can cause a capital loss when an investment is realized, unlike saving(s) where the more limited risk is cash devaluing due to inflation.
· In many instances the term saving and investment are used interchangeably which confuses this distinction. For example many deposit accounts are labeled as investment accounts by banks for marketing purposes. To help establish whether an asset is saving(s) or an investment you should consider where your money is invested. If the answer is cash then it is savings, if it is a type of asset which can fluctuate in value then it is investment.
Investment Management
Investing can be a complex activity and there have been countless books about investing that have been written over the years though certain books are considered classics because of their enduring principles that have stood the test of time. Many of the books on investing, including some of the seminal texts were written by investment managers and or famous investors like Peter Lynch, Phil Fisher or Benjamin Graham
Real Estate Investment
· Within real estate, money used to purchase property for the sole purpose of holding or leasing for income and where there is an element of capital risk is deemed a real estate investment. Real Estate investment is distinct from other forms of economic or financial investment in that a real estate is purchased.
