Indices in the Global Markets

An index is a method to track the performance of a group of assets. Indices typically measure the performance of a basket of securities intended to replicate a certain area of the market. Indexes in financial markets are used as benchmarks to evaluate an investment’s performance. Indices such as the S&P 500, DowJones, FTSE, DAX and others are the world’s best-known and commonly used benchmarks for the financial markets provided by FxPro.

What is the S&P 500 Index ?

The S&P 500 Index, or Standard & Poor’s 500 Index is a market-capitalization-weighted index of 500 leading publicly traded companies in the U.S. The S&P 500 index is one of the best gauges that represents the American overall economy.

Weighting Formula and Calculation for the S&P 500

The S&P 500 uses a market-cap weighting method, giving a higher percentage allocation to companies with the largest market capitalizations.

Company Weighting in S & P = Total of all market caps / Company market cap

Determining the weighting of each component of the S&P 500 begins with adding up the total market cap for the index by adding together the market cap of every company in the index.

The market cap of a company is calculated by taking the current stock price and multiplying it by the company’s outstanding shares. The total market cap for the S&P 500 as well as the market caps of individual companies are published frequently on financial websites or easily can be calculated.

The weighting of each company in the index is calculated by taking the company’s market cap and dividing it by the total market cap of the index.

Other S&P indexes

The S&P 500 is a member of the S&P Global 1200 family of indices. Other popular indices include the S&P MidCap 400, which represents the mid-cap range of companies, and the S&P SmallCap 600, which represents small-cap companies. The S&P 500, S&P MidCap 400, and S&P SmallCap 600 combine to create a U.S. all-capitalization index known as the S&P Composite 1500.

S&P 500 Index Construction

The S&P only uses free-floating publicly traded shares calculating market cap. The S&P adjusts each company’s market cap to compensate for new share issues or company mergers. The value of the index is calculated by the total of adjusted market caps of each company and dividing the result by a divisor. The divisor is proprietary information of the S&P and is not released to the public.

However, we can calculate a company’s weighting in the index, which can provide investors with valuable information. If a stock rises or falls, we can get a sense as to whether it might have an impact on the overall index. For example, a company with a 10% weighting will have a greater impact on the value of the index than a company with a 2% weighting.

The S&P 500 is one of the most widely quoted American indexes because it represents the largest publicly traded corporations in the U.S. The S&P 500 focuses on the U.S. market’s large-cap sector and is also a float-weighted index (a type of capitalization weighting), meaning company market capitalizations are adjusted by the number of shares available for public trading.
