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. The impact that individual stock's price change has on the index is proportional to the company's overall market value (the share price multiplied by the number of outstanding shares), in a capitalization-weighted index. In other types of indices, different ratios are used.

Telephone companies have dedicated phone numbers connected to mirror time servers that also relay the precise time. Another increasingly popular means of obtaining the time

252-424: Is the free-float weighting. With this method a float factor is assigned to each stock to account for the proportion of outstanding shares that are held by the general public, as opposed to "closely held" shares owned by the government, royalty, or company insiders (see float ). For example, if for some stock 15% of shares are closely held, and the other 85% are publicly held, the float factor will be 0.85, by which

432-461: The Indian markets. However the proposals of SEBI were not clear and this led to a knee-jerk crash when the markets opened on the following day (17 October 2007).

540-552: The United States, capitalization-weighted indices tended to use full weighting, i.e., all outstanding shares were included, while float-weighted indexing has been the norm in other countries, perhaps because of large cross-holdings or government ownership. More recently, many of the U.S. indices, such as the S&P 500, have been changed to a float -adjusted weighting which makes their calculation more consistent with non-U.S. indices. An index may also be classified according to

576-510: The company's market capitalization will be multiplied before weighting its value against the rest of the index. In other words, the number of shares used for calculation is the number of shares "floating", rather than outstanding. An index that is weighted in this manner is said to be "float-adjusted" or "float-weighted", in addition to being cap-weighted. For example, the S&;P 500 index is both cap-weighted and float-adjusted. Historically, in

SEBI was not happy with P-notes because it was not possible to know who owned the underlying securities, and hedge funds acting through P-notes might therefore cause volatility in

Thus, price movement of even a single security will heavily influence the value of the index even though the dollar shift is less significant in a relatively high-value name. In a fundamentally weighted index, stocks are weighted by fundamental factors like sales or book value. Indian Standard Time Indian Standard Time ( IST ), sometimes also called India Standard Time ,

On 27 July 2007 the SENSEX witnessed a huge decline because of selling by Foreign Institutional Investors and global cues to come back to 15,160 points by noon.

The index is calculated based on a free float capitalisation method, a variation of the market capitalisation method.
