A capitalization-weighted (or cap-weighted) index, also called a market-value-weighted index is a stock market index whose components are weighted according to the total market value of their outstanding shares. Every day an individual stock's price changes and thereby changes a stock index's value.
Both the cap-weighted market portfolio and the CAPM model are inefficient. If we assume that the capitalization-weighted market portfolio is not efficient, assuming a pricing inefficiency, capitalization-weighting might be sub-optimal and the degree of sub-performance might be proportional to the degree of random noise.

Stock market indices may be categorized by their index weight methodology, or the rules on how stocks are allocated in the index, independent of its stock coverage. For example, the S&P 500 and the S&P 500 Equal Weight each cover the same group of stocks, but the S&P 500 is weighted by market capitalization, while the S&P 500 Equal Weight places equal weight on each constituent.
Until 15 years ago, capitalization-weighted index funds were the only way to invest with this passive approach. Investors playing the odds tend to invest in passively managed index funds, growing ...
The equity risk premium is the difference between the expected total return on a capitalization-weighted stock market index and the yield on a riskless government bond (in this case one with 10 years to maturity).

[ 1 ] The Nasdaq Composite is a capitalization-weighted index ; its price is calculated by taking the sum of the products of closing price and index share of all of the ...
It covers roughly the small-cap range of American stocks, using a capitalization-weighted index. To be included in the index, a stock must have a total market capitalization that ranges from $1 billion to $6.7 billion. [1] These market cap eligibility criteria are for addition to an index, not for continued membership.
A price-weighted index is a stock market index where each constituent makes up a fraction of the index that is proportional to its component, the value would be: [1] Adjustment Factor = Index specific constant "Z" / (Number of shares of the stock * Adjusted stock market value before rebalancing)
