Actuaries
An actuary is a business professional who deals with the measurement and management of risk and uncertainty. The name of the corresponding field is actuarial science. These risks can affect both sides of the balance sheet and require asset management, liability management, and valuation skills. Actuaries provide assessments of financial security systems, with a focus on their complexity, their mathematics, and their mechanisms.

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. For example, the AMEX Composite Index (XAX) had more than 800 component stocks. The weighting of each stock constantly shifted with changes in the stock's price and the number of shares outstanding. The index fluctuates in line with the price move of the stocks. Stock market indices are a type of economic index. Free-float weighting A common version of capitalization weighting is the ''free-float'' weighting. ...
