alpha teriminin İngilizce İngilizce sözlükte anlamı: Alphabet; Latin alpha; An alpha male
Alpha males don’t do this because they’re too busy convincing everyone around them that they are alphas.; The name of the first letter of the Greek alphabet (Α, α), followed by beta. In the Latin alphabet it is the predecessor to A; Designates the first in an order of precedence
I am the alpha male.; The return of a given asset or portfolio adjusted for systematic risk; Designates the brightest star in a constellation
When space travel becomes feasible, I plan to visit Alpha Centauri.; The name of the symbols Α and α used in science and mathematics, often interchangeable with the symbols when used as a prefix
I will attempt to make an alpha particle (α-particle) with the large hadron collider.; {i} Greek letter; beginning; brightest star in a constellation; (in Computer Graphics) fourth color component (that allows control over blending colors with a background or hidden objects); {n} the Greek A or a; {a} the first; 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); first in order of importance; "the alpha male in the group of chimpanzees"; "the alpha star in a constellation is the brightest or main star"; 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; the beginning of a series or sequence; "the Alpha and Omega, the first and the last, the beginning and the end"--Revelations; 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; gen/uci A descriptive term used to define a character set containing the letters of an ethnic alphabet, and generally punctuation marks [MIL-HDBK-1908B]; 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; early testing stage of a software or hardware product; "alpha version"; A measure of selection risk (also known as residual risk) of a mutual fund in relation to the market A positive alpha is the extra return awarded to the investor for taking a risk, instead of accepting the market return For example, an alpha of 0 4 means the fund outperformed the market-based return estimate by 0 4% An alpha of -0 6 means a fund's monthly return was 0 6% less than would have been predicted from the change in the market alone In a Jensen Index, it is factor to represent the portfolio's performance that diverges from its beta, representing a measure of the manager's performance [Harvey]; Either refers to the first version, testing version of a program or the icqalpha mirabilis com server for the ICQ program ONLY!; (1) (n ) In computer graphics, a fourth color component Alpha is typically used to control color blending with a background or underlying object Typically, an alpha value of 1 0 implies complete opacity, and an alpha value of 0 0 is complete transparency (2) (n ) The first letter of the Greek alphabet; A numerical value indicating a portfolio manager's risk-adjusted excess rate of return relative to a benchmark Measures a portfolio manager's "value-added" in selecting individual securities, independent of the effect of overall market movements; the 1st letter of the Greek alphabet; The first letter in the Greek alphabet, answering to A, and hence used to denote the beginning; In finance, the amount by which a given asset or portfolios return exceeds a "riskless" rate of return; The highest scientific caste of people in the novel Brave New World by Aldous Huxley; first in order of importance; "the alpha male in the group of chimpanzees"; "the alpha star in a constellation is the brightest or main star; the 1st letter of the Greek alphabet the beginning of a series or sequence; "the Alpha and Omega, the first and the last, the beginning and the end"--Revelations early testing stage of a software or hardware product;
