This calculator will compute the absolute breadth index (ABI) for a stock market, given the number of advancing stocks in the market and the number of declining stocks in the market.

*The absolute breadth index is a measure of the amount of activity or change in a stock market. Larger ABI values indicate that the stock market is undergoing substantial change, while smaller values indicate that the stock market is relatively stable.*

This calculator will compute the alpha value (also known as the Average Differential Return) for a market security, given the security's beta value and market return rate, and the risk-free rate of return.

*Alpha values greater than zero indicate that an investment has produced larger returns than expected for its risk level, while values less than zero indicate that the investment has earned smaller returns than expected for its risk level.*

This calculator will compute the profit associated with an arbitrage transaction for a stock or commodity, given the higher price of the stock or commodity on one exchange, the lower price of the stock or commodity on another exchange, and the number of shares or units involved in the transaction.

*Arbitragers take advantage of inter-market inefficiencies by simultaneously buying and selling a stock or commodity on different exchanges in order to produce risk-free profits.*

This calculator will compute the beta value for an investment, given the covariance between the investment's returns and those of the market, and the variance of the market returns.

*An investment's beta value describes the relationship between the investment's returns and those of the market. Positive beta values indicate that an investment's returns tend to move in concert with the market, while negative values indicate that an investment's returns tend to move in an opposite direction from the market.*

This calculator will compute the book value per share for a company's common stock, given the total shareholders' equity, the liquidation value of any preferred stock, the amount of preferred dividends in arrears, and the number of shares of common stock outstanding.

*The book value per share of common stock represents the right that each share of common stock has to a company's net assets.*

This calculator will compute the book value per share for a company's preferred stock, given the liquidation value of the preferred stock, the amount of preferred dividends in arrears, and the number of shares of preferred stock outstanding.

*The book value per share of preferred stock represents the amount of shareholders' equity that is clearly assignable to preferred stock on a per share basis.*

This calculator will compute a company's cash flow from operations (CFO) per share, given the company's cash flow from operations and its total number of shares of common stock outstanding.

*The cash flow from operations per share ratio reveals the amount of cash that a company has for investing and financing its ongoing operations that is assignable to each share of its common stock.*

This calculator uses the capital asset pricing model (CAPM) to compute the expected rate of return for a stock, given the stock's beta value, the market rate of return, and the risk-free rate of return.

*The expected rate of return for a stock is based on the stock's level of risk in light of current market conditions.*

This calculator uses the capital asset pricing model (CAPM) to compute the risk premium for a stock, given the stock's beta value, the market rate of return, and the risk-free rate of return.

*The risk premium for a stock is the additional rate of return over and above the risk-free rate that an investor can expect to receive in exchange for assuming a higher level of risk.*
