Alpha Definition from Business & Finance Dictionaries & Glossaries
Campbell R. Harvey's Hypertextual Finance Glossary
Measure of risk-adjusted performance. An alpha is usually generated by regressing the security or mutual fund's excess return on the S&P 500 excess return. The beta adjusts for the risk (the slope coefficient). The alpha is the intercept. Example: Suppose the mutual fund has a return of 25%, and the short-term interest rate is 5% (excess return is 20%). During the same time the market excess return is 9%. Suppose the beta of the mutual fund is 2.0 (twice as risky as the S&P 500). The expected excess return given the risk is 2 x 9%=18%. The actual excess return is 20%. Hence, the alpha is 2% or 200 basis points . Alpha is also known as the Jensen Index. Related: Risk-adjusted return.

Smith's Bible Dictionary

(A), the first letter of the Greek alphabet. With Omega, the last letter, it is used in the Old Testament and in the New to express the eternity of God, as including both the beginning and the end. (Revelation 1:8,11; 21:6; 22:13; Isaiah 41:4; 44:6) hence these letters became a favorite symbol of the eternal divinity of our Lord, and were used for this purpose in connection with the cross, or the monogram of Christ (i.e. the first two letters, ch and r, of Christ's name in Greek). Both Greeks and Hebrews employed the letters of the alphabet as numerals.
