S&P 500 How Does is work?

S&P 500 is one of America's most trusted and respected stock market indices. It tracks the stocks of 505 large-cap US companies. Because it tracks the performance of some the largest companies in the country, it is considered a gauge of the US economy.

S&P500 - Features of The Index

S&P 500, currently owned by S&P Down Jones Indices, is the performance benchmark investors use to compare all their investments to, gauge profits, and see how the market does. Portfolio managers aim to beat the benchmark S&P500 index.

Because it covers 80 percent, the index has a high representational value. Officially launched March 4, 1957, the index derives its value through the value of the underlying stocks. It is dynamic. S&P Dow Jones currently owns the index.

What Does the Index Do?

It is essential to understand what market capitalization (cap) means in order to understand the function of an index. Market cap is the sum of all shares traded by a company. This is calculated by adding the number of shares on the market to the price per share. Based on market capital, the index tracks large-cap companies and enlists them. An index that tracks large-cap companies based on their market capital will include 10X more representation than a company worth $200 billion. The index had a total market capital of $21.42 trillion in March 2020. This is 9.2 percent less than it was one year ago, when it reached $23.62 trillion.

What is the Value of S&P500?

The free-float capitalisation method is used to value the index. This means that the stock price per share is multiplied by the number of shares traded in the public. This does not take into account shares held by government, promoters or private parties.

What is the method of calculating market weights?

Step 1. Calculate each large-cap stock's market cap in the index

Consider Apple, which has a large market share in the index.

Apple now has 4.8 billion shares publicly traded and each share trades at $149. Apple's total free-float value would then be the sum of each share price and $712 billion in publicly traded shares.

Step 3 Calculate the total market capital of all stocks

The market cap for all 500-505 companies in the index can then be added to calculate the total market capital.

Step 2 Calculate Individual market Weights

To determine how much stock from one company affects the value of an index, it is important to calculate individual market weights.

Simply divide the market cap of each stock by its total S&P500 market capital to get individual market weights. In March 2020, Microsoft Corporation held 5.4% of the total marketweight in S&P500. Amazon.com Inc, Apple Inc and Facebook had 4.8, 3.6, and 1.8% respectively of the market weights. The index's value will be affected by the market weight and the percentage of changes in its stock prices.

Each quarter, the index is calibrated in March, June and September, then December. It is possible for the sector-wise breakdown to change. For example, IT and IT enabled services made up 24.4 percent of stocks in the index in March 2020. Healthcare accounted for 14 percent, financial services 12.2 percent, and consumer stables accounted for 7.2 percent. Real estate was at 3.1 percent.

What is the Index Divisor?

The index value is calculated using a price-weighted aggregate method. To keep the calculation of the index's values manageable, an index uses a proprietary value, or the index divisor, to reduce the index to a scale that can be reported. This is how it works: When an index is first created, we add the stock prices to get the initial value. The index divisor is used to reduce the added value of stock prices, making calculations easier for large companies with large market capitals. The divisor also serves another purpose: it reduces the impact of stock splits and dividends as well as buybacks on the overall index value.

Qualifications of a Company for Listing on S&P 500

These requirements must be met in order for a company to be included in the S&P500 Index. These requirements are not enough to make a company eligible for listing on the exchange. A high-powered committee selects companies based upon their industry, size, and liquidity.

1. The United States must be the home of the company.

2. It should have a market capital (unadjusted), of at least $8.2 billion by 2020.

3. Stock price must not be less than $1 per share

4. Annual 10K report required

5. 50 percent must be from the United States.

6. Public trading must allow for 50 percent of company stock.

7. Should have reported four quarters consecutively of positive net profit.

It shouldn't be listed on a pink list. The stock should not be listed on any lists of stocks that are traded over-the-counter. Should be listed on NYSE, Investors Exchange, Nasdaq or BATS Global Markets.

Competing Market Indices

The Dow Jones Industrial Average, or the Dow Jones Industrial Average, is the second-most important stock market index in America. It represents 30 stocks of high-quality large-cap companies. It is far less representative of the stock market than S &P 500, as it has fewer shares. It does not use the free floating market-cap-weighted method for calculating the market weights of the included stocks. The Dow's market cap total is approximately one-fourth the US stock market capital. S&P500 is different from Nasdaq Composite. This is because unlike S&P500, it includes privately traded shares. These indices move in line with the market direction, influenced by market forces.

Conclusion

Understanding the S&P500's workings is crucial to understand the US economy and markets, given its directional value. The index will show whether an economy is in recession or emerging from it. Because they account for 80 percent of the market capital, S&P500 stocks are also a major indicator of market movements.
