The beta (β) of a stock or portfolio is a number describing the volatility of an asset in relation to the volatility of the benchmark that said asset is being compared to. This benchmark is generally the overall financial market and is often estimated via the use of representative indices , such as the S&P 500 .
Phi (/ f aɪ /; [1] uppercase Φ, lowercase φ or ϕ; Ancient Greek: ϕεῖ pheî; Modern Greek: φι fi) is the twenty-first letter of the Greek alphabet. In Archaic and Classical Greek (c. 9th to 4th century BC), it represented an aspirated voiceless bilabial plosive ( [pʰ] ), which was the origin of its usual romanization as ph .
Differences between alpha and beta. Though both greek letters, alpha and beta are quite different from each other. Alpha is a way to measure excess return, while beta is used to measure the ...
ω (omega) is the angle in the chain C α − C' − N − C α, φ (phi) is the angle in the chain C' − N − C α − C' ψ (psi) is the angle in the chain N − C α − C' − N (called φ′ by Ramachandran) The figure at right illustrates the location of each of these angles (but it does not show correctly the way they are defined).

Between Ancient and Modern Greek, they have remained largely unchanged, except that their pronunciation has followed regular sound changes along with other words (for instance, in the name of beta, ancient /b/ regularly changed to modern /v/, and ancient /ɛː/ to modern /i/, resulting in the modern pronunciation vita).
Phi phenomenon has long been confused with beta movement; however, the founder of Gestalt School of Psychology, Max Wertheimer, has distinguished the difference between them in 1912. While Phi phenomenon and Beta movement can be considered in the same category in a broader sense, they are quite distinct indeed. Firstly, the difference is on ...
Representatives of Alpha Omega Alpha, the Order of the Coif, Phi Beta Kappa, and Sigma Xi attended its preliminary meeting held on October 2, 1925. When ACHS was officially established on December 30, 1925, its founding members were Alpha Omega Alpha, the Order of the Coif, Phi Beta Kappa, Phi Kappa Phi, Sigma Xi, and Tau Beta Pi. [2]
