Alpha
The expected return of a stock or a portfolio if the market rate of return is zero
A measure of the manager's contribution to performance, is expressed as an annual compounded rate of return, adjusted for risk Alpha represents the difference between the actual performance and the expected performance of a fund given its volatility (or risk) The expected value for alpha is zero If positive, the fund has achieved a return above that expected for its volatility A negative alpha reflects fund performance below that expected for its volatility
The probability that a particular statistical test on a particular set of cases is committing a Type I error and falsely declaring an effect that does not really exist In graphical terms, the alpha is the percent of the estimated normal curve of the population that falls outside of the confidence interval on either one or both sides of the curve (depending on the nature of the hypothesis being tested)
A numerical investment measure sometimes used as a performance indicator or to aid in selection of securities Alpha is the premium an investment would be expected to earn if the market rate of return were equal to the Treasury bill rate, e g , a premium of zero for the market rate of return A positive alpha indicates that you have earned on the average a premium above that expected for the level of market variability A negative alpha indicates, on the average, a premium lower than that expected for the level of market variability See also Beta
A coefficient measuring the risk-adjusted performance, considering the risk due to the specific security, rather than the overall market A large alpha indicates that the stock or mutual fund has performed better than would be predicted given its beta (volatility)

A value representing a pixel's degree of transparency The more transparent a pixel, the less it hides the background against which the image is presented In PNG, alpha is really the degree of opacity: zero alpha represents a completely transparent pixel, maximum alpha represents a completely opaque pixel But most people refer to alpha as providing transparency information, not opacity information, and we continue that custom here

Alpha measures a stock's average monthly move over the past 12 months if the S&P 500 index is unchanged during this 12-month period For example, a stock with a high alpha of 7 would be expected to rise 7% in a month given an unchanged S&P 500 index

A measure of a portfolio's return in excess of the market return, after both have been adjusted for volatility It is also a measure of the manager's contribution to performance due to security selection A positive alpha indicates that the portfolio outperformed the market on a volatility adjusted basis, and a negative alpha indicates the portfolio did worse than the market Alpha is based on historical performance of the trailing 36 months and does not indicate future results Source: Russell
is the measurement of returns from an investment in excess of market returns It represents the amount expected from fundamental causes, e g the growth rate in earnings per share This contrasts with BETA, which is a measure of risk or volatility
The extent to which an asset or portfolio's actual return exceeds or falls short of the expected return - the expected return is a function of the stock or portfolio's Beta When positive, alpha is often referred to as "extraordinary" or "abnormal" returns
The extent to which an asset or portfolio's actual returns exceed or fall short of the expected returns - the expected return is a function of the stock or portfolio's Beta When positive, alpha is often referred to as "extraordinary" or "abnormal" returns For more see our Tutorial on Market Risk Exposure (Alpha, Beta and R-Squared)
A measure of risk adjusted performance used to quantify the difference between the security's actual performance and the performance anticipated in light of the security's risk (beta) and the market’s (relative market index) behavior In short, alpha tells how much better, or worse, a security did relative to what it was expected to do based on its risk posture A positive alpha indicates a security's return has been more than commensurate with its risk posture Higher numbers are better than lower
Alpha is the risk-adjusted return of a portfolio or security The alpha for a portfolio or security is the difference between the actual return and expected return A positive alpha would indicate that the portfolio or security had performed better than what was implied by its relationship with the market
A measure of a fund's risk-adjusted return Alpha can be used to directly measure the value added or subtracted by a fund's manager It is calculated by measuring the difference between a fund's actual returns and its expected performance given its level of market risk as measured by beta An alpha of 1 0 means the fund produced a return 1% higher than its beta would predict An alpha of -1 0 means the fund produced a return 1% lower The accuracy of an alpha rating depends on two factors: 1) the assumption that market risk, as measured by beta, is the only risk measure necessary; 2) the strength of fund's correlation to a chosen benchmark such as the S&P 500 Correlation is measured by R-squared An R-squared of less than 50 makes a fund's alpha rating virtually meaningless BACK TO TOP
The alpha coefficient measures the portion of an investment's return arising from specific (non-market) risk It can be a positive or a negative number Often referred to as a manager's "value added" (or "value subtracted"), alpha measures the difference between actual returns and expected performance resulting from exposure to specific risk factors
Alpha is the measure of a fund's average performance independent of the market, (i e if the market return was zero ) For example, if a fund has an alpha of 2 0, and the market return was 0% for a given month, then the fund would, on average, return 2% for the month To view the formula for Alpha, please download the word document
An Alpha is a RISC processor invented by Digital and currently produced by Digital/Compaq and Samsung A few different OSes run on Alpha based machines including Digital UNIX, Windows NT, Linux, NetBSD, and AmigaOS Historically, at any given time, the fastest processor in the world has usually been either an Alpha or a PowerPC (with sometimes SPARCs and PA-RISCs making the list), but Compaq has recently announced that there will be no further development of this superb processor instead banking on the release of the somewhat suspect Merced
