Calculation of the index
Unlike the Dow Jones or Dax. The S&P 500 is calculated as a price index and therefore does not include dividend payments. Stock splits also have no distorting effect on the price trend. The calculation is based on the so-called value index formula. This calculation takes into account the performance of each individual share. However, larger companies have more influence on the performance than smaller companies.
The calculation of the index is updated every second, at least during the trading hours of the New York Stock Exchange. This is open from 15:30 to 22:00 German time. In addition, the S&P500 is the basis for the CBOE Volatility Index.

Value stocks in health care, industry or consumer goods have been able to generate top returns over long periods of time. The technology sector has served as a key growth driver in recent years.

The best from the USA. Since its inception, the S&P 500 has always produced good returns if you have been in it for the long term. This is a good middle ground between the Dow Jones and the Nasdaq 100. The Dow Jones mainly represents value stocks and is therefore not as volatile as the Nasdaq 100, because it mainly lists growth companies. The S&P 500 combines both, which is also reflected in the return.
