Return (finance)
In finance, return is a profit on an investment. It comprises any change in value of the investment, and/or cash flows (or securities, or other investments) which the investor receives from that investment over a specified time period, such as interest payments, coupons, cash dividends and stock dividends. It may be measured either in absolute terms (e.g., dollars) or as a percentage of the amount invested. The latter is also called the holding period return. A loss instead of a profit is described as a '' negative return'', assuming the amount invested is greater than zero. To compare returns over time periods of different lengths on an equal basis, it is useful to convert each return into a return over a period of time of a standard length. The result of the conversion is called the rate of return. Typically, the period of time is a year, in which case the rate of return is also called the annualized return, and the conversion process, described below, is called ''annualiz ...

Time-weighted Return
The time-weighted return (TWR) is a method of calculating investment return, where returns over sub-periods are compounded together, with each sub-period weighted according to its duration. The time-weighted method differs from other methods of calculating investment return, in the particular way it compensates for external flows. External flows The time-weighted return is a measure of the historical performance of an investment portfolio which compensates for ''external flows''. External flows refer to the net movements of value into or out of a portfolio, stemming from transfers of cash, securities, or other financial instruments. These flows are characterized by the absence of a concurrent, equal, and opposite value transaction, unlike what occurs in purchases or sales. Furthermore, they do not originate from the income generated by the portfolio's investments, such as interest, coupons, or dividends. To compensate for external flows, the overall time interval under analysis i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflation Rate
In economics, inflation is an increase in the average price of goods and services in terms of money. This increase is measured using a price index, typically a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. Changes in inflation are widely attributed to fluctuations in real demand for goods and services (also known as demand shocks, including changes in fiscal or monetary policy), changes in available supplies such as during energy crises (also known as supply shocks), or changes in inflation expectations, which may be self-fulfilling. Moderate inflation affects economies in both positive and negative ways ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purchasing Power
Purchasing power refers to the amount of products and services available for purchase with a certain currency unit. For example, if you took one unit of cash to a store in the 1950s, you could buy more products than you could now, showing that the currency had more purchasing power back then. If one's income remains constant but prices rise, their purchasing power decreases. Inflation does not always result in decreased purchasing power, especially if income exceeds price levels. A larger real income means more purchasing power, as it corresponds to the income itself. Traditionally, the purchasing power of money depended heavily upon the local value of gold and silver, but was also made subject to the availability and demand of certain goods on the market. Most modern fiat currencies, like US dollars, are traded against each other and commodity money in the secondary market for the purpose of international Balance transfer, transfer of payment for goods and services.

Profitability Index
Profitability index (PI), also known as profit investment ratio (PIR) and value investment ratio (VIR), is the ratio of payoff to investment of a proposed project. It is a useful tool for ranking projects because it allows you to quantify the amount of value created per unit of investment. Under capital rationing, PI method is suitable because PI method indicates relative figure i.e. ratio instead of absolute figure. The ratio is calculated as follows: *\text = \frac = 1 + \frac Assuming that the cash flow calculated does not include the investment made in the project, a profitability index of 1 indicates break-even. Any value lower than one would indicate that the project's present value ( PV) is less than the initial investment. As the value of the profitability index increases, so does the financial attractiveness of the proposed project. The PI is similar to the Return on Investment (ROI), except that the net profit is discounted In finance, discounting is a mechanism ...

Internal Rate Of Return
Internal rate of return (IRR) is a method of calculating an investment's rate of return. The term ''internal'' refers to the fact that the calculation excludes external factors, such as the risk-free rate, inflation, the cost of capital, or financial risk. The method may be applied either ex-post or ex-ante. Applied ex-ante, the IRR is an estimate of a future annual rate of return. Applied ex-post, it measures the actual achieved investment return of a historical investment. It is also called the discounted cash flow rate of return (DCFROR)Project Economics and Decision Analysis, Volume I: Deterministic Models, M.A.Main, Page 269 or yield rate. Definition (IRR) The IRR of an investment or project is the "annualized effective compounded return rate" or rate of return that sets the net present value (NPV) of all cash flows (both positive and negative) from the investment equal to zero. Equivalently, it is the interest rate at which the net present value of the future cash fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital Budgeting
Capital budgeting in corporate finance, corporate planning and accounting is an area of capital management that concerns the planning process used to determine whether an organization's long term capital investments such as new machinery, replacement of machinery, new plants, new products, and research development projects are worth the funding of cash through the firm's capitalization structures (debt, equity or retained earnings). It is the process of allocating resources for major capital, or investment, expenditures. An underlying goal, consistent with the overall approach in corporate finance, is to increase the value of the firm to the shareholders. Capital budgeting is typically considered a non-core business activity as it is not part of the revenue model or models of most types of firms, or even a part of daily operations. It holds a strategic financial function within a business. One example of a firm type where capital budgeting is possibly a part of the core bu ...

Difference Of Squares
In elementary algebra, a difference of two squares is one square (algebra), squared number (the number multiplied by itself) subtraction, subtracted from another squared number. Every difference of squares may be Factorization, factored as the Multiplication, product of the addition, sum of the two numbers and the Subtraction, difference of the two numbers: a^2-b^2 = (a+b)(a-b). In the reverse direction, the product of any two numbers can be expressed as the difference between the square of their arithmetic mean, average and the square of half their difference: xy = \left(\frac\right)^2 - \left(\frac\right)^2. Proof Algebraic proof The mathematical proof, proof of the factorization identity is straightforward. Starting from the Sides of an equation, right-hand side, apply the distributive law to get (a+b)(a-b) = a^2+ba-ab-b^2. By the commutative law, the middle two terms cancel: ba - ab = 0 leaving (a+b)(a-b) = a^2-b^2. The resulting identity is one of the most commonly used i ...

Volatility (finance)
In finance, volatility (usually denoted by "sigma, σ") is the Variability (statistics), degree of variation of a trading price series over time, usually measured by the standard deviation of logarithmic returns. Historic volatility measures a time series of past market prices. Implied volatility looks forward in time, being derived from the market price of a market-traded derivative (in particular, an option). Volatility terminology Volatility as described here refers to the actual volatility, more specifically: * actual current volatility of a financial instrument for a specified period (for example 30 days or 90 days), based on historical prices over the specified period with the last observation the most recent price. * actual historical volatility which refers to the volatility of a financial instrument over a specified period but with the last observation on a date in the past **near synonymous is realized volatility, the square root of the realized variance, in turn c ...

AM–GM Inequality
In mathematics, the inequality of arithmetic and geometric means, or more briefly the AM–GM inequality, states that the arithmetic mean of a list of non-negative real numbers is greater than or equal to the geometric mean of the same list; and further, that the two means are equal if and only if every number in the list is the same (in which case they are both that number). The simplest non-trivial case is for two non-negative numbers and , that is, :\frac2 \ge \sqrt with equality if and only if . This follows from the fact that the square of a real number is always non-negative (greater than or equal to zero) and from the identity : :\begin 0 & \le (x-y)^2 \\ & = x^2-2xy+y^2 \\ & = x^2+2xy+y^2 - 4xy \\ & = (x+y)^2 - 4xy. \end For a geometrical interpretation, consider a rectangle with sides of length and ; it has perimeter and area . Similarly, a square with all sides of length has the perimeter and the same area as the rectangle. The simplest non-tri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost Of Capital
In economics and accounting, the cost of capital is the cost of a company's funds (both debt and equity), or from an investor's point of view is "the required rate of return on a portfolio company's existing securities". It is used to evaluate new projects of a company. It is the minimum return that investors expect for providing capital to the company, thus setting a benchmark that a new project has to meet. Basic concept For an investment to be worthwhile, the expected return on capital has to be higher than the cost of capital. Given a number of competing investment opportunities, investors are expected to put their capital to work in order to maximize the return. In other words, the cost of capital is the rate of return that capital could be expected to earn in the best alternative investment of equivalent risk; this is the opportunity cost of capital. If a project is of similar risk to a company's average business activities it is reasonable to use the company's average co ...
