Definition of Simple moving average

Simple moving average

Arms index

Also known as a trading index (TRIN)= (number of advancing issues)/ (number of declining
issues) (Total up volume )/ (total down volume). An advance/decline market indicator. Less than 1.0 indicates
bullish demand, while above 1.0 is bearish. The index often is smoothed with a simple moving average.

Arithmetic average (mean) rate of return

Arithmetic mean return.

Average

An arithmetic mean of selected stocks intended to represent the behavior of the market or some
component of it. One good example is the widely quoted Dow Jones Industrial average, which adds the
current prices of the 30 DJIA's stocks, and divides the results by a predetermined number, the divisor.

Average accounting return

The average project earnings after taxes and depreciation divided by the average
book value of the investment during its life.

Average age of accounts receivable

The weighted-average age of all of the firm's outstanding invoices.

Average collection period, or days' receivables

The ratio of accounts receivables to sales, or the total
amount of credit extended per dollar of daily sales (average AR/sales * 365).

Average cost of capital

A firm's required payout to the bondholders and to the stockholders expressed as a
percentage of capital contributed to the firm. average cost of capital is computed by dividing the total
required cost of capital by the total amount of contributed capital.

Average life

Also referred to as the weighted-average life (WAL). The average number of years that each
dollar of unpaid principal due on the mortgage remains outstanding. average life is computed as the weighted average time to the receipt of all future cash flows, using as the weights the dollar amounts of the principal
paydowns.

Average maturity

The average time to maturity of securities held by a mutual fund. Changes in interest rates
have greater impact on funds with longer average life.

An estimation of price that uses the average or representative price of a
large number of trades.

Average rate of return (ARR)

The ratio of the average cash inflow to the amount invested.

Average tax rate

Taxes as a fraction of income; total taxes divided by total taxable income.

Dow Jones industrial average

This is the best known U.S.index of stocks. It contains 30 stocks that trade on
the New York Stock Exchange. The Dow, as it is called, is a barometer of how shares of the largest
U.S.companies are performing. There are thousands of investment indexes around the world for stocks,
bonds, currencies and commodities.

Moving average

Used in charts and technical analysis, the average of security or commodity prices
constructed in a period as short as a few days or as Long as several years and showing trends for the latest
interval. As each new variable is included in calculating the average, the last variable of the series is deleted.

Simple prospect

An investment opportunity where a certain initial wealth is placed at risk and only two
outcomes are possible.

Simple compound growth method

A method of calculating the growth rate by relating the terminal value to
the initial value and assuming a constant percentage annual rate of growth between these two values.

Simple interest

Interest calculated only on the initial investment. Related:compound interest.

Simple linear regression

A regression analysis between only two variables, one dependent and the other explanatory.

Simple linear trend model

An extrapolative statistical model that asserts that earnings have a base level and
grow at a constant amount each period.

Weighted average cost of capital

Expected return on a portfolio of all the firm's securities. Used as a hurdle
rate for capital investment.

Weighted average coupon

The weighted average of the gross interest rate of the mortgages underlying the
pool as of the pool issue date, with the balance of each mortgage used as the weighting factor.

Weighted average life

See:average life.

Weighted average maturity

The WAM of a MBS is the weighted average of the remaining terms to maturity
of the mortgages underlying the collateral pool at the date of issue, using as the weighting factor the balance
of each of the mortgages as of the issue date.

Weighted average remaining maturity

The average remaining term of the mortgages underlying a MBS.

Weighted average portfolio yield

The weighted average of the yield of all the bonds in a portfolio.

WEIGHTED AVERAGE

An inventory valuation method that calculates a weighted average cost per unit for all the goods available for sale.
Multiplying that figure by the total units in ending inventory gives you the inventory’s value.

Weighted average cost of capital

See cost of capital.

Weighted average

A method of accounting for inventory.

weighted-average cost of capital

Weighted means that the proportions of
debt capital and equity capital of a business are used to calculate its
average cost of capital. This key benchmark rate depends on the interest
rate(s) on its debt and the ROE goal established by a business. This is a
return-on-capital rate and can be applied either on a before-tax basis or
an after-tax basis. A business should earn at least its weighted-average
rate on the capital invested in its assets. The weighted-average cost-ofcapital
rate is used as the discount rate to calculate the present value
(PV) of specific investments.

Average Collection Period

average number of days necessary to receive cash for the sale of
a company's products. It is calculated by dividing the value of the
accounts receivable by the average daily sales for the period.

Simple Interest

Interest paid only on the principal; calculated by multiplying the
interest rate by the principal

Weighted Average Cost of Capital (WACC)

The weighted average of the costs of the capital components
(debt, preferred stock, and common stock)

simple interest

a method of determining interest in which interest is earned only on the original investment (or principal) amount

simple regression

a statistical technique that uses only one independent variable to predict a dependent variable

simplex method

an iterative (sequential) algorithm used to solve multivariable, multiconstraint linear programming problems

weighted average cost of capital

a composite of the cost of the various sources of funds that comprise a firm’s capital structure; the minimum rate of return that must be earned on new investments so as not to dilute shareholder value

weighted average method (of process costing)

the method of cost assignment that computes an average cost per
equivalent unit of production for all units completed during
the current period; it combines beginning inventory units
and costs with current production and costs, respectively,
to compute the average

Moving average

A price average that is adjusted by adding other
parametrically determined prices over some time period.

Moving-averages chart

A financial chart that plots leading and lagging
moving averages for prices or values of an asset.

Average inventory

The beginning inventory for a period, plus the amount at the end of
the period, divided by two. It is most commonly used in situations in which just
using the period-end inventory yields highly variable results, due to constant and
large changes in the inventory level.

Moving average inventory method

An inventory costing methodology that calls for the re-calculation of the average cost of all parts in stock after every purchase.
Therefore, the moving average is the cost of all units subsequent to the latest purchase,
divided by their total cost.

average tax rate

Total taxes owed divided by total income.

cost of beginning inventory and inventory purchases during a period to cost of goods sold and
