A mathematical representation of the typical value of a series of numbers, computed as the sum of all the numbers in the series divided by the count of all numbers in the series.

Arithmetic mean is commonly referred to as "average" or simply as "mean".

Suppose you wanted to know what the arithmetic mean of a stock's closing price was over the past week. If during the five-day week the stock closed at $14.50, $14.80, $15.20, $15.50, and then $14.00, its arithmetic mean closing price would be equal to the sum of the five numbers ($74.00) divided by five, or $14.80.

A series of technical indicators used by traders to predict the direction of the major financial indexes. Most market indicators are created by analyzing the number of companies that have reached new highs relative to the number that created new lows, also known as market breadth.

Some of the most common market indicators are: Advance/Decline Index, Absolute Breadth Index, Arms Index and McClellan Oscillator. A general outlook on the market's direction is useful for traders looking for strength in individual equities because they ensure that the broader market forces are working in their favor.

The stage of the economy's business cycle that marks the end of a period of declining business activity and the transition to expansion.



In general, the business cycle is said to go through expansion, then the peak, followed by contraction, and then it finally bottoms out with the trough.

A short-term technical analysis breadth indicator calculated as the following:

Arms  Index (TRIN)

TRIN stands for TRaders' INdex.

A ratio of 1 means the market is in balance; above 1 indicates that more volume is moving into declining stocks; and below 1 indicates that more volume is moving into advancing stocks. This indicator was developed by Richard Arms.

A technical indicator that plots changes in the value of the advance-decline index over a certain time period. Each point on the chart is calculated by taking the difference between the number of advancing/declining issues and adding the result to the previous period's value, as shown by the following formula:

A/D Line = (# of Advancing Stocks - # of Declining Stocks) + Previous Period's A/D Line Value

This indicator is used by many traders to confirm the strength of a current trend and its likelihood of reversing. If the markets are up but the A/D line is sloping downwards, it's usually a sign that the markets are losing their breadth and may be setting up to head in the other direction. If the slope of the A/D line is up and the market is trending upward then the market is said to be healthy.

The highest point between the end of an economic expansion and the start of a contraction in a business cycle. The peak of the cycle refers to the last month before several key economic indicators, such as employment and new housing starts, begin to fall. It is at this point that real GDP spending in an economy is its highest level.

Business cycles are dated according to when the direction of economic activity changes and is measured by the time it takes for an economy to go from one peak to another. Also, because economic indicators change at different times, it is the National Bureau of Economic Research that ultimately determines the official dates of peaks and troughs in U.S. business cycles.

A technical indicator that uses three parallel trendlines to identify possible levels of support and resistance. The trendlines are created by placing three points at the end of identified trends. This is usually achieved by placing the points in three consecutive peaks or troughs. Once the points have been placed, a straight line is drawn from the first point that intersects the midpoint of the other two.

Also known as "median line studies".



The chart shown here makes it clear why this indicator is called a pitchfork. The first point drawn on the chart forms the handle, while the lines extending from the other two points will make up the prongs.

The difference in price from the midpoint of a trough to the midpoint of a peak of a security. Amplitude is positive when calculating a bullish retracement (when calculating from trough to peak) and negative when calculating a bearish retracement (when calculating from peak to trough).

Amplitude is calculated often in technical analysis. For example, it is the amount of retracement in a price and also the width of a channel in a range-bound market.

Chart pattern analysis says that after a retracement, price will continue to move at least a distance equal to the retracement's amplitude.

A market indicator used to determine volatility levels in the market without factoring in price direction. It is calculated by taking the absolute value of the difference between the number of advancing issues and the number of declining issues. Typically, large numbers suggest volatility is increasing, which is likely to cause significant changes in stock prices in the coming weeks.

This tool is classified as a breadth indicator because the advancing/declining values are the only values used to create it. This index can be calculated using any exchange or a subset of an exchange, but traditionally the New York Stock Exchange has been the accepted standard.

An order to buy or sell at a price set higher than the current market price of the security. Examples of above the market orders include: a limit order to sell, a stop order to buy, or a stop-limit order to buy.

This is a strategy that is often used by momentum traders. For example, a stop order would be placed above the resistance level to buy. Should the security's price break through the resistance level, the investor may be able to participate in the upward trend.

A indicator used by traders to gauge a security's long-term trend by comparing bars which contain its opening, closing, high and low prices throughout a specific period of time. When the ASI is positive, it suggests that the long-term trend will be higher, and when the ASI is negative, it suggests that the long-term trend will be lower.

The ASI is often cited as being developed by Welles Wilder.

While the ASI is most often used for futures trading, it can be used for analyzing the price trends of other assets as well. The ASI may be used in conjunction with price charts in order to confirm trendline breakouts, because the same trendline would be penetrated in both situations.

A momentum indicator that attempts to gauge supply and demand by determining whether investors are generally "accumulating" (buying) or "distributing" (selling) a certain stock by identifying divergences between stock price and volume flow. It is calculated using the following formula:

Acc/Dist = ((Close – Low) – (High – Close)) / (High – Low) * Period's volume

For example, many up days occurring with high volume in a downtrend could signal that the demand for the underlying is starting to increase. In practice, this indicator is used to find situations in which the indicator is heading in the opposite direction as the price. Once this divergence has been identified, the trader will wait to confirm the reversal and make his or her transaction decisions using other technical indicators.

Portfolio Turnover

A measure of how frequently assets within a fund are bought and sold by the managers. Portfolio turnover is calculated by taking either the total amount of new securities purchased or the amount of securities sold - whichever is less - over a particular period, divided by the total net asset value (NAV) of the fund. The measurement is usually reported for a 12-month time period.

The portfolio turnover measurement should be considered by an investor before deciding to purchase a given mutual fund or similar financial instrument. After all, a firm with a high turnover rate will incur more transaction costs than a fund with a lower rate. Unless the superior asset selection renders benefits that offset the added transaction costs they cause, a less active trading posture may generate higher fund returns.

In addition, cost conscious fund investors should take note that the transactional brokerage fee costs are not included in the calculation of a fund's operating expense ratio and thus represent what can be, in high-turnover portfolios, a significant additional expense that reduces investment return.

Any exchange-traded fund that seeks to provide high dividend yields by investing in a basket of high-dividend paying common stocks, preferred stocks or REITs. There are dividend ETFs that contain only U.S. domestic stocks and global dividend ETFs, which have an international focus. The indexes used to create dividend ETFs vary by fund manager or custodian, but most contain stocks with a high level of liquidity and above-market dividend yields.


Although dividend ETFs are passively managed around an index, that index may be the result of certain quantitative screens such as companies with a history of increasing their dividends, or larger blue-chip companies with a higher level of perceived safety. The expense ratios of dividend ETFs should be comparable to, or lower than, the cheapest no-load mutual funds with similar investment objectives. As with all ETFs, dividend ETFs can be traded intraday. These types of funds may be part of the core portfolio of an income-seeking or generally risk-averse stock investor.

What Does Diversification Mean?
A risk management technique that mixes a wide variety of investments within a portfolio. The rationale behind this technique contends that a portfolio of different kinds of investments will, on average, yield higher returns and pose a lower risk than any individual investment found within the portfolio.

Diversification strives to smooth out unsystematic risk events in a portfolio so that the positive performance of some investments will neutralize the negative performance of others. Therefore, the benefits of diversification will hold only if the securities in the portfolio are not perfectly correlated.

Studies and mathematical models have shown that maintaining a well-diversified portfolio of 25 to 30 stocks will yield the most cost-effective level of risk reduction. Investing in more securities will still yield further diversification benefits, albeit at a drastically smaller rate.

Further diversification benefits can be gained by investing in foreign securities because they tend be less closely correlated with domestic investments. For example, an economic downturn in the U.S. economy may not affect Japan's economy in the same way; therefore, having Japanese investments would allow an investor to have a small cushion of protection against losses due to an American economic downturn.

Most non-institutional investors have a limited investment budget, and may find it difficult to create an adequately diversified portfolio. This fact alone can explain why mutual funds have been increasing in popularity. Buying shares in a mutual fund can provide investors with an inexpensive source of diversification.



An exchange-traded fund (ETF) that is constructed by using various derivatives for the purpose of profiting from a decline in the value of an underlying benchmark. Investing in these ETFs is similar to holding various short positions, or using a combination of advanced investment strategies to profit from falling prices.

Also known as a "Short ETF," or "Bear ETF".

One advantage is that these ETFs do not require the investor to hold a margin account as would be the case for investors looking to enter into short positions.

There are several inverse ETFs that can be used to profit from declines in broad market indexes, such as the Russell 2000 or the Nasdaq 100. In addition, it is possible to buy inverse ETFs that focus on a specific sector, such as financials, energy or consumer staples. Most investors look to purchase inverse ETFs so that they can hedge their portfolios against falling prices.

A category of expenditure that a business incurs as a result of performing its normal business operations. One of the typical responsibilities that management must contend with is determining how low operating expenses can be reduced without significantly affecting the firm's ability to compete with its competitors.

Also known as "OPEX".

For example, the payment of employees' wages and funds allocated toward research and development are operating expenses. In the absence of raising prices or finding new markets or product channels in order to raise profits, some businesses attempt to increase the bottom line purely by cutting expenses.

While laying off employees and reducing product quality can initially boost earnings and may even be necessary in cases where a company has lost its competitiveness, there are only so many operating expenses that management can cut before the quality of business operations is damaged.

What Does Active Investing Mean?
An investment strategy involving ongoing buying and selling actions by the investor. Active investors purchase investments and continuously monitor their activity in order to exploit profitable conditions.

Active investing is highly involved. Unlike passive investors, who invest in a stock when they believe in its potential for long-term appreciation, active investors will typically look at the price movements of their stocks many times a day. Typically, active investors are seeking short-term profits.

The person or persons responsible for investing a mutual, exchange-traded or closed-end fund's assets, implementing its investment strategy and managing the day-to-day portfolio trading.

The portfolio manager is one of the most important factors to consider when looking at fund investing. Portfolio management can be active or passive (index tracking). Historical performance records indicate that only a minority of active fund managers beat the market indexes.

What Does Active Management Mean?
The use of a human element, such as a single manager, co-managers or a team of managers, to actively manage a fund's portfolio. Active managers rely on analytical research, forecasts, and their own judgment and experience in making investment decisions on what securities to buy, hold and sell. The opposite of active management is called passive management, better known as "indexing".

Investors who believe in active management do not follow the efficient market hypothesis. They believe it is possible to profit from the stock market through any number of strategies that aim to identify mispriced securities.

Investment companies and fund sponsors believe it's possible to outperform the market, and employ professional investment managers to manage one or more of the company's mutual funds. The objective with active management is to produce better returns than those of passively managed index funds. For example, a large cap stock fund manager would look to beat the performance of the Standard & Poor's 500 Index. Unfortunately, for a large majority of active managers, this has been difficult. This phenomenon is simply a reflection of how hard it is, no matter how smart the manager, to beat the market.
