bank-sponsored plans - a direct stock purchase plan (DSP) or dividend reinvestment plan (DRIP) that is administered by a bank rather than the company itself.

bond swaps - a municipal bond investment strategy that lets you take a tax loss and adjust your bond portfolio for credit quality and maturities to meet market considerations and your personal needs.

call - an option contract that gives the holder the right to buy the underlying security at a specific price for a specific period of time. Calls can be bought or sold.

Board contrarian strategy - an investing strategy that appears to go against the mood of the market, buying heavily during sluggish, pessimistic markets and selling during periods of market optimism.

covered call - a call option written by a person who owns the underlying security.

day order - an order to buy or sell a security that expires at the end of the day.

day trading - the practice of basing trades on market fluctuations during the day and closing out positions by the end of the trading day.

delayed quotes - stock quotes that are delayed by the exchanges 15 or 20 minutes from real-time.

direct investment plan (DIP) - allows an individual to buy shares directly from a company. Also called a direct stock purchase plan (DSP).

dividend reinvestment plan (DRIP) - this plan automatically purchases a company's stock with a shareholder's dividends from that stock.

Ticker Dow dividend approach - an investing strategy that invests equally in the 10 stocks of the Dow 30 that pay the highest dividends.

DRIP - see dividend reinvestment plan

DRP - see DRIP

DSP - see DIP

exponential moving average - a moving average smooths the fluctuations in stock prices by averaging the prices over a specified period. An exponential moving average gives heavier weight to the most recent data.

fundamental analysis- evaluating a stock by assessing a company's intrinsic worth and growth potential based on such factors as historical earnings, projected earnings, revenues, cash flow, and various financial ratios.

fundamentals - factors that contribute to a company's basic financial health, such as earnings, revenues, cash flow, debt level, and financial ratios.

long - refers to securities owned by an investor and held in the investor's brokerage account.

LSQ line - LSQ stands for a mathematical formula called "least squares." In technical analysis, an LSQ line is a trend line that determines the midpoint of price data on a stock graph.

market top - a point at which a long-term uptrend reverses and the market heads downward.

mental stop - a reminder to reevaluate a stock if it falls to a specified level. The reminder can be a visual flag in an online portfolio or an e-mail message from the Web site that maintains the portfolio.

moving average - the average of a stock price over a specified time period. A moving average smooths price and volume fluctuations and emphasizes the direction of a trend. An exponential moving average gives greater weight to the most recent price action.

Share price graph moving average convergence/divergence (MACD) - a trading method based on the crossing of two exponential moving averages above and below a zero line. (A third moving average plots the difference between the other two and forms a single line.) The convergence and divergence of the moving averages generate buy and sell signals.

net asset value (NAV) - the price paid for a mutual fund share. The NAV is computed daily by summing the values of all the fund's investments, subtracting expenses and liabilities, and dividing that number by the number of outstanding shares.

no-load - the absence of sales commissions, as in no-load mutual funds.

partial fill - a limit order that is only partially filled because the total specified shares could not be bought or sold at the specified price.

quarter-over-quarter earnings - a comparison of a company's current quarterly earnings per share with its earnings per share for the same quarter last year.

real-time quotes - stock quotes that include the most recent trade, as opposed to quotes that are delayed 15 or 20 minutes by the exchanges.

redemption fee - a fee charged by some mutual funds when an investor sells shares in the fund. Also called a back-end load.

screen - one or more characteristics that are used as a filter to eliminate stocks that don't have those characteristics.

short interest - the number of a company's shares that have been sold short and not yet repurchased, frequently reported as the number of days it would take to cover the short position, assuming the volume of stock stays at its average volume traded over the past 30 days.

Ticker rounding corner short selling - selling a security you don't own (borrowed from your broker) with the intention of buying it at a lower price to replace the borrowed shares. Short sellers are betting the price will go down.

spread - the gap between the bid and the ask prices of a security.

stop-limit order - a variation on the stop order; a stop-limit order will be executed only at the limit price, not higher or lower than the limit price. In contrast, a stop order will be executed at the stop price, or, should the stock gap up or down, at the higher- or lower-than-stop price.

stop order - an order placed at a price that is higher (a buy stop) or lower (a sell stop) than the current market price. Buy stops are used by short sellers; sell stops are employed by investors who trade long. Both are used to protect profits and limit losses.

Strategic Indexing - the use of an investing strategy that has been back-tested over a long period of time and has exceeded a target index, such as the S&P 500.

street name - refers to the registered holder of a security when it is held in the broker's name, rather than in the name of the person who owns the stock.

support - a price level that represents a floor for falling stock prices. It is a price at which buying has historically entered, thereby tending to limit declines below this level.

tick - an incremental change of a stock price. An uptick means the trade was higher than the one before; a downtick means the trade was lower than the previous level.

trading bands - on a stock graph, an envelope drawn within a set distance on either side of a moving average to delineate a stock's trading range.

trend break - the movement of the stock price through a trend line. A positive trend break is a move upward through a downward trend line; a negative trend break is a move downward through an upward trend line.

trend line - a line on a stock graph that connects a series of highs or lows to delineate an uptrend (representing support) or a downtrend (representing resistance).

underlying security - the stock, bond, index, or other financial instrument upon which a derivative such as an option is based. It is the underlying security that is subject to being bought or sold upon exercise of the option.

upgrades/downgrades - analysts make buy/hold/sell recommendations for the stocks they follow. An upgrade is a change from a sell to a hold or buy, or from a hold to a buy. A downgrade is a change from a buy to a hold or sell, or from a hold to a sell.

watch list - a list or portfolio of stock prospects that you are watching with an eye for an optimum entry point.

whipsaws - very frequent reversals of a stock between buy and sell signals, based on various technical indicators; also called chatter.

whisper numbers - figures widely believed by "those in the know" on Wall Street to be the true earnings that a company will achieve in the next quarter. The whisper numbers often exceed the earnings estimate published by analysts. When a company announces earnings that meet or even exceed the analysts' estimates but fail to meet the whisper numbers, the stock price will often drop.
