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 ...
Over this period the average return was 13.9% of 30-stock Magic Formula portfolio versus 9.3% for the BSE Sensex. [9] An analysis of the Hong Kong stock market from 2001 to 2014 found Greenblatt's formula was associated with long-term outperformance of market averages by 6-15% depending on company size and other variables.

Beta is the hedge ratio of an investment with respect to the stock market. For example, to hedge out the market-risk of a stock with a market beta of 2.0, an investor would short $2,000 in the stock market for every $1,000 invested in the stock. Thus insured, movements of the overall stock market no longer influence the combined position on ...
[2] [7] [8] Benjamin Clark, the founder of the blog and investment service ModernGraham, acknowledges the footnote and argues that "I consider the footnote to be more of a reminder from Graham that the calculation of an intrinsic value [9] is not an exact science and cannot be done with 100% certainty."
These equations show that the stock return is influenced by the market (beta), has a firm specific expected value (alpha) and firm-specific unexpected component (residual). Each stock's performance is in relation to the performance of a market index (such as the All Ordinaries). Security analysts often use the SIM for such functions as ...
Example of the optimal Kelly betting fraction, versus expected return of other fractional bets. In probability theory, the Kelly criterion (or Kelly strategy or Kelly bet) is a formula for sizing a sequence of bets by maximizing the long-term expected value of the logarithm of wealth, which is equivalent to maximizing the long-term expected geometric growth rate.
Stock valuation is the method of calculating theoretical values of companies and their stocks.The main use of these methods is to predict future market prices, or more generally, potential market prices, and thus to profit from price movement – stocks that are judged undervalued (with respect to their theoretical value) are bought, while stocks that are judged overvalued are sold, in the ...
For example, suppose a put option with a strike price of $100 for ABC stock is sold at $1.00 and a put option for ABC with a strike price of $90 is purchased for $0.50, and at the option's expiration the price of the stock or index is greater than the short put strike price of $100, then the return generated for this position is:
