Betaindicates an asset’s contribution to the total risk of a portfolio. As the effective diversification eliminates almost all of an asset’s unique risk, the relative measure of a single asset’s risk is not its standard deviation, but it’s beta. Individual Stock and Market Portfolio.īetapicks up the risk that cannot be diversified away. The most interesting parameters in the line are the intercept and beta coefficient. In the regression analysis, the term е it in the Equation is a random-error term which will have a mean value of zero and is assumed to be uncorrelated with the market returns, the error terms of other securities, and error terms of the same security over time. The straight line in the figure represents the line of best fit between the return on stock I and market return. The characteristic line shows the return an investorexpects the stock to produce, given that a particular rate of return appears for the market. If we relate the return from an individual stock to the market return in this way, the line of best fit refers to the stock’s characteristic line. This line helps in describing the relationship between the return from individual stock and that of the market portfolio or market return. The line passing through the observations is the line of best fit. The pairs of returns can be plotted in the figure.

Market capitalization of the largest and smallest securities in each portfolio Market capitalization of each portfolio, reported in thousands Three return series (Total Return and Index Level, Capital Appreciation Return and Index Level, and Income Return and Index Level). Quarterly portfolio returns are obtained by compounding the three monthly returns. Delisted securities are researched to determine a final value for their final return. New securities are added to the decile portfolios based on their initial market capitalization relative to the breakpoint. Security weights are determined using market capitalizations based on the shares outstanding and closing price for the last trading day of the previous month. Portfolio returns are value-weighted and calculated monthly. The NYSE American and NASDAQ National Markets securities are then added into the deciles created from the NYSE breakpoints. Capitalization-based breakpoints used to determine the next quarter portfolio assignments are derived from these decile rankings. All NYSE securities are ranked into decile portfolios on the last trading day of the quarter. The universe contains NYSE, NYSE American, and NASDAQ common stocks of US companies. Reports with information on breakpoints, performance, and rebalancing are generated from the CRSP Cap-Based Portfolio Module. The CRSP Cap-Based Portfolios examine the relationship between the size of market capitalization and returns.
