History of the S&P 500

In 1999, Standard & Poor alongside Morgan Stanley Capital International developed the GICS, or the Global Industry Classification Standard. The GICS is used to sort publicly traded companies into different sectors based on the primary function of the business. The GICS is then used to create indexes, which provide insight into global or country specific economies. There are many types of indexes, but they are often based off the capitalization or sector exposure of companies. These indexes are usually market or price weighted, meaning every stock in the index is represented in the index proportionally to its total market weight.

One of the most well-known indexes, the S&P 500, represents the top 500 companies in the U.S. This index on average represents about 80% of total value in the U.S. stock market, meaning that this index is a good indicator as to how the U.S. market is performing. Another well known index is the Dow Jones Industrial Average, often referred to simply as the Dow. The Dow represents 30 of the most large and influential companies in the U.S. This index is typically known for its listing of the best blue-chip companies with consistent dividends but should not be used as a representation of the whole market. The final index I will mention is the Nasdaq Composite Index, which includes all stocks traded on the Nasdaq exchange. This index is a little different than those previously mentioned because some of the companies in the index are not based in the U.S. This index is known to be tech heavy, including software, biotech, semiconductors and more, but because it includes all stocks from the Nasdaq exchange, it also contains many small and/or speculative companies. The Nasdaq Composite Index is considered a good indicator on the performance of the technology industry, as well as how investors feel about more speculative stocks.
