Excerpt: In finance, the Beta ( ) of a stock or portfolio is a number describing the relation of its returns with those of the financial market as a whole. An asset has a Beta of zero if its returns change independently of changes in the market's returns. A positive beta means that the asset's returns generally follow the market's returns, in the sense that they both tend to be above their respective averages together, or both tend to be below their respective averages together. A negative beta means that the asset's returns generally move opposite the market'...
