Definition of Normal portfolio

Normal portfolio

A customized benchmark that includes all the securities from which a manager normally
chooses, weighted as the manager would weight them in a portfolio.

CARs (cumulative abnormal returns)

a measure used in academic finance articles to measure the excess returns an investor would have received over a particular time period if he or she were invested in a particular stock.
This is typically used in control and takeover studies, where stockholders are paid a premium for being taken over. Starting some time period before the takeover (often five days before the first announced bid, but sometimes a longer period), the researchers calculate the actual daily stock returns for the target firm and subtract out the expected market returns (usually calculated using the firm’s beta and applying it to overall market movements during the time period under observation).
The excess actual return over the capital asset pricing model-determined expected return market is called an ‘‘abnormal return.’’ The cumulation of the daily abnormal returns over the time period under observation is the CAR. The term CAR(-5, 0) means the CAR calculated from five days before the
announcement to the day of announcement. The CAR(-1, 0) is a control premium, although Mergerstat generally uses the stock price five days before announcement rather than one day before announcement as the denominator in its control premium calculation. However, the CAR for any period other than (-1, 0) is not mathematically equivalent to a control premium.

Abnormal returns

Part of the return that is not due to systematic influences (market wide influences). In
other words, abnormal returns are above those predicted by the market movement alone. Related: excess
returns.

Active portfolio strategy

A strategy that uses available information and forecasting techniques to seek a
better performance than a portfolio that is simply diversified broadly. Related: passive portfolio strategy

The entire portfolio, including risky and risk-free assets.

Cumulative abnormal return (CAR)

Sum of the differences between the expected return on a stock and the
actual return that comes from the release of news to the market.

Related: cash flow matching.

Efficient portfolio

A portfolio that provides the greatest expected return for a given level of risk (i.e. standard
deviation), or equivalently, the lowest risk for a given expected return.

A portfolio consisting of the long position in the stock and the short position in the call
option, so as to be riskless and produce a return that equals the risk-free interest rate.

Leveraged portfolio

A portfolio that includes risky assets purchased with funds borrowed.

Lognormal distribution

A distribution where the logarithm of the variable follows a normal distribution.
Lognormal distributions are used to describe returns calculated over periods of a year or more.

Also called a mean-variance efficient portfolio, a portfolio that has the highest
expected return at a given level of risk.

Markowitz efficient set of portfolios

The collection of all efficient portfolios, graphically referred to as the
Markowitz efficient frontier.

Mean-variance efficient portfolio

Related: Markowitz efficient portfolio

Minimum-variance portfolio

The portfolio of risky assets with lowest variance.
Minority interest An outside ownership interest in a subsidiary that is consolidated with the parent for
financial reporting purposes.

Modern portfolio theory

Principles underlying the analysis and evaluation of rational portfolio choices
based on risk-return trade-offs and efficient diversification.

Normal annuity form

The manner in which retirement benefits are paid out.

Normal backwardation theory

Holds that the futures price will be bid down to a level below the expected
spot price.

Normal deviate

Related: standardized value

Normal probability distribution

A probability distribution for a continuous random variable that is forms a
symmetrical bell-shaped curve around the mean.

Normal random variable

A random variable that has a normal probability distribution.

Normalizing method

The practice of making a charge in the income account equivalent to the tax savings
realized through the use of different depreciation methods for shareholder and income tax purposes, thus
washing out the benefits of the tax savings reported as final net income to shareholders.

Optimal portfolio

An efficient portfolio most preferred by an investor because its risk/reward characteristics
approximate the investor's utility function. A portfolio that maximizes an investor's preferences with respect
to return and risk.

Passive portfolio strategy

A strategy that involves minimal expectational input, and instead relies on
diversification to match the performance of some market index. A passive strategy assumes that the
marketplace will reflect all available information in the price paid for securities, and therefore, does not
attempt to find mispriced securities. Related: active portfolio strategy

Passive portfolio

A market index portfolio.

Portfolio

A collection of investments, real and/or financial.

Portfolio insurance

A strategy using a leveraged portfolio in the underlying stock to create a synthetic put
option. The strategy's goal is to ensure that the value of the portfolio does not fall below a certain level.

Portfolio internal rate of return

The rate of return computed by first determining the cash flows for all the
bonds in the portfolio and then finding the interest rate that will make the present value of the cash flows
equal to the market value of the portfolio.

Portfolio opportunity set

The expected return/standard deviation pairs of all portfolios that can be
constructed from a given set of assets.

Portfolio separation theorem

An investor's choice of a risky investment portfolio is separate from his
attitude towards risk. Related:Fisher's separation theorem.

Portfolio turnover rate

For an investment company, an annualized rate found by dividing the lesser of
purchases and sales by the average of portfolio assets.

Portfolio variance

Weighted sum of the covariance and variances of the assets in a portfolio.

Replicating portfolio

A portfolio constructed to match an index or benchmark.

Standardized normal distribution

A normal distribution with a mean of 0 and a standard deviation of 1.

Structured portfolio strategy

A strategy in which a portfolio is designed to achieve the performance of some
predetermined liabilities that must be paid out in the future.

Tilted portfolio

An indexing strategy that is linked to active management through the emphasis of a
particular industry sector, selected performance factors such as earnings momentum, dividend yield, priceearnings
ratio, or selected economic factors such as interest rates and inflation.

Weighted average portfolio yield

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

Well diversified portfolio

A portfolio spread out over many securities in such a way that the weight in any
security is small. The risk of a well-diversified portfolio closely approximates the systemic risk of the overall
market, the unsystematic risk of each security having been diversified out of the portfolio.

Zero-beta portfolio

A portfolio constructed to represent the risk-free asset, that is, having a beta of zero.

Zero-investment portfolio

A portfolio of zero net value established by buying and shorting component
securities, usually in the context of an arbitrage strategy.

Portfolio

A collection of securities and investments held by an investor

Portfolio Diversification

See diversification

Portfolio Weight

The percentage of a total portfolio represented by a single specific
security. It is calculated by dividing the value of the investment in a
specific security by the value of the investment in the total portfolio.

net cost of normal spoilage

the cost of spoiled work less the estimated disposal value of that work

normal capacity

the long-run (5–10 years) average production
or service volume of a firm; it takes into consideration
cyclical and seasonal fluctuations

normal cost system

a valuation method that uses actual
costs of direct material and direct labor in conjunction with
a predetermined overhead rate or rates in determining the
cost of Work in Process Inventory

normal loss

an expected decline in units during the production process

normal spoilage

spoilage that has been planned or foreseen; is a product cost

Normal (bell-shaped) distribution

In statistics, a theoretical frequency
distribution for a set of variable data, usually represented by a bell-shaped
curve symmetrical about the mean.

Spoilage, abnormal

Spoilage arising from the production process that exceeds the normal
or expected rate of spoilage. Since it is not a recurring or expected cost of ongoing
production, it is expensed to the current period.

Spoilage, normal

The amount of spoilage that naturally arises as part of a production
process, no matter how efficient that process may be.

market portfolio

portfolio of all assets in the economy. In practice a broad stock market index, such as the Standard & Poor's Composite, is used to represent the market.

Market Portfolio

The total of all investment opportunities available to the investor.

Index Portfolio Rebalancing Service (IPRS)

Index portfolio Rebalancing Service (IPRS) is a comprehensive investment service that can help increase potential returns while reducing volatility. Several portfolios are available, each with its own strategic balance of Index Funds. IPRS maintains your personal asset allocation by monitoring and rebalancing your portfolio semi-annually.

Expense ratio

The percentage of the assets that were spent to run a mutual fund (as of the last annual
statement). This includes expenses such as management and advisory fees, overhead costs and 12b-1
(distribution and advertising ) fees. The expense ratio does not include brokerage costs for trading the
portfolio, although these are reported as a percentage of assets to the SEC by the funds in a Statement of
Additional Information (SAI). the SAI is available to shareholders on request. Neither the expense ratio or the
SAI includes the transaction costs of spreads, normally incurred in unlisted securities and foreign stocks.
These two costs can add significantly to the reported expenses of a fund. The expense ratio is often termed an
Operating Expense Ratio (OER).
