The term () represents the movement of the market modified by the stock's beta, while represents the unsystematic risk of the security due to firm-specific factors. Macroeconomic events, such as changes in interest rates or the cost of labor, causes the systematic risk that affects the returns of all stocks, and the firm-specific events are the ...
Put another way, a stock priced below the Graham Number would be considered a good value, if it also meets a number of other criteria. The Number represents the geometric mean of the maximum that one would pay based on earnings and based on book value. Graham writes: [2] Current price should not be more than 1 1 ⁄ 2 times the book value last ...
Graham also cautioned that his calculations were not perfect, even in the time period for which it was published, noting in the 1973 edition of The Intelligent Investor: "We should have added caution somewhat as follows: The valuations of expected high-growth stocks are necessarily on the low side, if we were to assume these growth rates will ...

Thus insured, movements of the overall stock market no longer influence the combined position on ...
Their book A Non-Random Walk Down Wall Street, presents a number of tests and studies that reportedly support the view that there are trends in the stock market and that the stock market is somewhat predictable.

If a stock doesn't pay dividends, other methods using distributable cash flows, may be utilized. The duration of an equity is a noisy analogue of the Macaulay duration of a bond, due to the variability and unpredictability of dividend payments. The duration of a stock or the stock market is implied rather than deterministic.
[3] [4] Their work borrowed heavily from the theoretical and mathematical ideas found in John Burr Williams 1938 book "The Theory of Investment Value," which put forth the dividend discount model 18 years before Gordon and Shapiro. When dividends are assumed to grow at a constant rate, the variables are: is the current stock price.
