This article explains what makes the S&P 500 Index stand out among other indices. Before we elaborate on the S&P 500, however, a short definition of an index is in order.
An index is a method to evaluate the performance of a group of assets. As a rule, indices measure the performance of a group of securities meant to replicate a specific area of the market. These can be so-called broad-based indices tracking the whole market. Indices can also be more specialized, evaluating a specific industry or a segment.
What Is the S&P 500 Index?
The index under discussion is called the Standard & Poor’s 500 Index, or the S&P 500 for short. It is an index of the 500 largest US companies which are traded publicly. The index is market-capitalization weighted; that is, it is a type of the index where its individual components are included in amounts corresponding to their total market capitalization, shortened as “market cap”.
What Companies Are Eligible for S&P 500 Inclusion?
Note that the S&P 500 is not a list of exactly 500 US companies by market capitalization, since there are other criteria by which companies get included in the index. To be eligible for S&P 500 index inclusion, a company should satisfy the following criteria:
- Be a US company;
- Have a market capitalization of at least USD 11.8 billion;
- Be highly liquid;
- Have a public float of at least 10% of its shares outstanding;
- Its most recent quarter’s earnings and the sum of its trailing four consecutive quarters’ earnings must be positive.
What Companies Are Listed on the S&P 500?
The S&P 500 Index is viewed as the best gauge of large-cap US equities. The Index does not provide the full list of 500 companies, many of which include technology companies and financial businesses. The top ten S&P 500 companies by Index weighting are the following:
- Apple Inc. (AAPL), index weighting is 5.9%.
- Microsoft Corp. (MSFT), index weighting is 5.4%.
- Amazon.com., Inc, index weighting is 4.2%.
- Facebook, Inc. (FB), index weighting is 2.2%.
- Alphabet Inc. Class A (GOOGL), index weighting is 2.0%.
- Alphabet Inc. Class C (GOOG), index weighting is 2.0%.
- Tesla Inc. (TSLA), index weighting is 1.5%.
- Berkshire Hathaway Inc. (BRK.B), index weighting is 1.5%.
- JPMorgan Chase & Co. (JPM0, index weighting is 1.3%.
- Johnson & Johnson (JNJ), index weighting is 1.2%.
While many of these above-mentioned companies may be household names, broad popular familiarity is not a requirement. That means that the index also includes lesser-known companies, so long as they meet the criteria for index inclusion.
What Is Inside the S&P 500 Index?
There are eleven sectors included in the S&P 500 Index, according to the Global Industry Classification Standard:
- Energy
- Materials
- Industrials
- Consumer Discretionary
- Consumer Staples
- Health Care
- Financials
- Information Technology
- Communication Services
- Real Estate
- Utilities
These sectors are further divided into 24 industry groups, 69 industries, and 158 sub-industries. The S&P 500 represents more than 83% of the total domestic U.S. equity market capitalization. The S&P Composite 1500®, which comprises the S&P 500, S&P MidCap 400®, and S&P SmallCap 600®, represents over 90% of the S&P TMI (Total Market Index).
History of the S&P 500
The origin of the S&P 500 goes back to 1923 when Standard & Poor’s introduced indices that included 233 companies spread over 26 industries. The S&P 500, as it is now known, was introduced in 1957. The S&P 500 is regarded as a proxy for the U.S. equity market. It is the only stock market benchmark serving as an economic indicator in The Conference Board Leading Economic Index. It has stood for U.S. stock market performance in that context since 1968.
S&P 500 Index Construction
In order to calculate the market capitalization of a company, one needs to multiply the current stock price by the outstanding shares; that is, those shares that are shown on a company’s balance sheet under the heading Capital Stock. Note that the S&P only uses free-floating shares or the shares that are traded by the public. The S&P 500 adjusts each company’s cap to compensate for the issues of new shares or companies’ mergers. The value of the index is calculated by totaling the adjusted market caps of each company and dividing the result by a divisor.
Investors can calculate how much a particular company weights in the index. This information is important: if a stock jumps or sinks, investors, by calculating its weight, can understand whether it might have an impact on the S&P 500 as a whole. A company with a 15% weighting will affect the value of the S&P 500 more than a company with a 1% weighting.
S&P 500 Most Recent Rebalancing
The S&P 500 was rebalanced last time on March 12, 2021. The rebalancing was brought into effect on March 22, 2021, before markets opened. NXP Semiconductors (NXPI), Penn National Gaming (PENN), Generac Holdings (GNRC), Caesars Entertainment (CZR) were included on the list of S&P 500 companies. Xerox Holdings (XRX), Flowserve (FLS), SL Green Realty (SLG), and Voter (VNT) were crossed out of the list.

In Asia, there are several large indices. The most popular among them are the following:
- The Hang Seng – This is a market capitalization-weighted index of the largest companies that trade on the Hong Kong Exchange.
- The Nikkei 225 – This is the leading index of Japanese stocks. It is composed of Japan’s top 225 blue-chip companies traded on the Tokyo Stock Exchange.
- The ASX 200 – This is a market-capitalization-weighted stock market index of stocks listed on the Australian Securities Exchange.
How Are Indices Calculated?
Most stock market indices are calculated using the Capitalization-Weighted Average. This method gives greater weighting to larger-cap companies. That is, it takes the size of each company into account. The more a particular company is worth, the more share’s price will affect the index as a whole. Lower cap companies will affect the index’s performance to a lesser degree.
Some popular indices are, by contrast, price-weighted. The Dow Jones and the Nikkei 225 are price-weighted indices. This method gives greater weighting to companies with higher share prices. Changes in their values will affect the current price of an index more than changes in companies with lower share prices: a stock trading at $200 will influence the value of the Dow Jones or the Nikkei more than a stock trading at $55.
Note that because indices are numbers, you cannot sell or buy them directly. To trade a certain index with Crypt2bay, you need to choose either Index Funds or Exchange-traded funds, or Futures, or Options, or CFDs. All of these products track the price of the underlying index. Also note that because they are made of so many stocks, the value of indices is always shifting. Indices are more volatile than individual shares. They do provide traders with multiple trading opportunities. Yet they also increase traders’ risk.
Why Do You Need to Trade Indices?
Despite the risks involved in trading indices, any index can potentially provide you with many trading opportunities and various ways of trading. When you trade indices, you can go long or short, trade with leverage, and hedge your existing positions.
- Go Long or Short
You can go long or short when trading an index with Crypt2bay, provided you trade it with CFDs. When you go long, you are buying a market, because you expect the price to jump. When you go short, you are selling a market, because you predict that the price will slide. With CFDs, your profit or loss is determined by the accuracy of your prediction together with the overall size of the market movement.
- Trade with Leverage
CFDs can be leveraged. That is, you need to invest only a small initial deposit, called a margin, to open a position giving you much larger market exposure. But note that when you trade with leverage, your profit or loss is calculated using the size of the entire position, not just the initial margin invested to open it.
- Hedge Your Existing Position
If you trade different shares, you may short your index to prevent losses in your portfolio. When the market enters negative territory and shares’ value diminishes, the short position on the index will increase in value and will thus offset the losses from the stocks. But note that when stocks rise, the short position of the index will offset a proportion of the profits you have earned.
But suppose you have a short position on several individual stocks featuring on the index where you trade. If this is the case, you can hedge against the risk of the price’s increase with a long position on the index. When the index jumps, your index position will bring you a profit and, in so doing, will offset a proportion of the losses on your short stock positions.
More volatile than individual shares, indices can bring you lucrative trading opportunities and handsome profits. Sign up with Crypt2bay now and confidently trade indices with us.
