Investment has different meanings in finance and economics. Finance investment is putting money into something with the expectation of gain, that upon thorough analysis, has a high degree of security for the principal amount, as well as security of return, within an expected period of time.[1] In contrast putting money into something with an expectation of gain without thorough analysis, without security of principal, and without security of return is speculation or gambling. As such, those shareholders who fail to thoroughly analyze their stock purchases, such as owners of mutual funds, could well be called speculators. Indeed, given the efficient market hypothesis, which implies that a thorough analysis of stock data is irrational, all rational shareholders are, by definition, not investors, but speculators.
Investment is related to saving or deferring consumption. Investment is involved in many areas of the economy, such as business management and finance whether for households, firms, or governments.
To avoid speculation an investment must be either directly backed by the pledge of sufficient collateral or insured by sufficient assets pledged by a third party.[original research?] A thoroughly analyzed loan of money backed by collateral with greater immediate value than the loan amount may be considered an investment. A financial instrument that is insured by the pledge of assets from a third party, such as a deposit in a financial institution insured by a government agency may be considered an investment. Examples of these agencies include, in the United States, the Securities Investor Protection Corporation, Federal Deposit Insurance Corporation, or National Credit Union Administration, or in Canada, the Canada Deposit Insurance Corporation.

In economic theory or in macroeconomics, investment is the amount purchased per unit time of goods which are not consumed but are to be used for future production (ie. capital). Examples include railroad or factory construction. Investment in human capital includes costs of additional schooling or on-the-job training. Inventory investment is the accumulation of goods inventories; it can be positive or negative, and it can be intended or unintended. In measures of national income and output, "gross investment" (represented by the variable I) is also a component of gross domestic product (GDP), given in the formula GDP = C + I + G + NX, where C is consumption, G is government spending, and NX is net exports. Thus investment is everything that remains of total expenditure after consumption, government spending, and net exports are subtracted (i.e. I = GDP − C − G − NX).
Non-residential fixed investment (such as new factories) and residential investment (new houses) combine with inventory investment to make up I. "Net investment" deducts depreciation from gross investment. Net fixed investment is the value of the net increase in the capital stock per year.
Fixed investment, as expenditure over a period of time ("per year"), is not capital. The time dimension of investment makes it a flow. By contrast, capital is a stock— that is, accumulated net investment to a point in time (such as December 31).
Investment is often modeled as a function of Income and Interest rates, given by the relation I = f(Y, r n2fmortgages Homeequitymortgagepayment Q Payment Szh Static Eaboutus Home Equity Mortgage Payment Investment - pedia, the free encyclopediaf Payment f2fmortgages Homeequitymortgagepayment Q Payment Szh Static Eaboutus Home Equity Mortgage Payment Investment - pedia, the free encyclopediaj o Loan Investment
