Some sources (including the file Highlights/Lowlights of The Dow on the Dow Jones website) show a loss of ?24.39% (from 71.42 to 54.00) on December 12, 1914, placing that day atop the list of largest percentage losses. The New York Stock Exchange reopened that day following a nearly four-and-a-half-month closure since July 30, 1914, and the Dow in fact rose several percent that day (from 71.42 to 74.56, or +4.4%). However, the apparent decline was due to a later 1916 revision of the Dow Jones Industrial Average, which retroactively adjusted the values following the closure but not those before, and it represents the only discontinuity in the index’s history rather than an actual loss.[3][4]

Largest intraday point swings

A point swing is the difference between the intraday high and the intraday low. (The intraday high may not be the same as the opening price — for instance, in the 2010 Flash Crash the market reached an intraday high higher than the opening price).[5]

This is distinguished from an intraday point drop, which is the different between the opening price and the intraday low.

This table shows the largest intraday point swings since 1987.[6] As the "Net Change" column shows, 15 of these 20 largest intraday swings occurred during days in which the Dow declined, while only 5 occurred during days in which it advanced. Eight of the ten largest intraday swings occurred amidst the global financial crisis of 2007-08, and none of the top 20 occurred before the year 2000. At the time during the height of the crisis, nine of the ten largest intraday swings ever (and 13 of the top 20) occurred over a single span of trading days between September 29, 2008 and December 1, 2008.

Largest intraday point changes

Largest intraday point gains

An intraday point gain is defined as the difference between the opening price (which may or may not be the intraday low) and the intraday high. This is distinguished from an intraday point gain, which is defined as the difference between the intraday high and the intraday low. Such records that turned negative are also recorded in a separate list. The opening price is used to calculate the point gain. The previous day close is used to calculate the net change.

Largest intraday point drops

An intraday point drop is defined as the difference between the opening price (which may or may not be the intraday high) and the intraday low. This is distinguished from an intraday point loss, which is defined as the difference between the intraday high and the intraday low. Such records that turned positive are also recorded in a separate list. The opening price is used to calculate the point drop. The previous day close is used to calculate the net change.

The Standard & Poor's 500, often abbreviated as the S&P 500, or just "the S&P",[6][7] is an American stock market index based on the market capitalizations of 500 large companies having common stock listed on theNYSE or NASDAQ. The S&P 500 index components and their weightings are determined by S&P Dow Jones Indices. It differs from other U.S. stock market indices, such as the Dow Jones Industrial Average or theNasdaq Composite index, because of its diverse constituency and weighting methodology. It is one of the most commonly followed equity indices, and many consider it one of the best representations of the U.S. stock market, and a bellwether for the U.S. economy.[8] The National Bureau of Economic Research has classified common stocks as a leading indicator of business cycles.[9]

The S&P 500 was developed and continues to be maintained by S&P Dow Jones Indices, a joint venture majority-owned by McGraw Hill Financial. S&P Dow Jones Indices publishes many stock market indices such as theDow Jones Industrial AverageS&P MidCap 400, the S&P SmallCap 600, and the S&P Composite 1500. It is a free-float capitalization-weighted index,[5] and has many ticker symbols, such as: ^GSPC,[10] INX,[11] and $SPX.[12]

History[edit]

Standard & Poor's introduced its first stock index in 1923. The S&P 500 index in its present form began on March 4, 1957. Technology has allowed the index to be calculated and disseminated in real time. The S&P 500 is widely used as a measure of the general level of stock prices, as it includes both growth stocks and value stocks.

In September 1962, Ultronic Systems Corp. entered into an agreement with Standards and Poor’s. Under the terms of this agreement, Ultronics computed the S&P 500 Stock Composite Index, the 425 Stock Industrial Index, the 50 Stock Utility Index, and the 25 Stock Rail Index. Throughout the market day these statistics were furnished to Standard & Poor’s. In addition, Ultronics also computed and reported the 94 S&P sub-indexes.[13]

Price history[edit]

On August 12, 1982, the index closed at 102.42.

The index reached a relative intraday high—which was not exceeded for over seven years—of 1,552.87, on March 24, 2000, during the dot-com bubble. The index then declined by approximately 50%, to 768.63, on October 10, 2002, during the stock market downturn of 2002.[14] On May 30, 2007, the S&P 500 closed at 1,530.23, to set its first all-time closing high in more than seven years. Although the index achieved a new all-time intraday high on October 11, 2007, at 1,576.09, following a record close of 1,565.15 on October 9, the index finished 2007 at 1,468.36 points—just below its 1999 annual close. Less than a month later, it dropped to 1,400, and would not see similar levels again for five years.

In mid-2007, the subprime mortgage crisis spread to the wider U.S. financial sector. The resulting situation became acute in September 2008, ushering in a period of unusual market volatility, encompassing record 100-point swings in both directions and reaching the highest levels since 1929.[15] On November 20, 2008, the index closed at 752.44, its lowest since early 1997.[16] A modest recovery the following day still left the index down 45.5% for the year. This year-to-date loss was the greatest since 1931, when the broad market declined more than 50%.[17] The index closed the year at 903.25, for a loss of 38.5%.[18] The market continued to decline in early 2009, surrounding the financial crisis of 2008. The index reached a nearly 13-year low, closing at 676.53, on March 9, 2009.

On March 23, 2009, the S&P 500 marked a 20% gain when it hit 822.92.[19] The Dow Jones Industrial Average soon followed.[20] The close for 2009 was 1,115.10, making it the second-best year of the decade.[21] On April 14, 2010 the index broke 1200 closing at 1210.65, but by July 2, 2010 it had closed at 1022.58. On April 29, 2011, the index closed at 1363.61, but it had a sharp drop in August and briefly broke 1100 in October (with the VIXhitting 40). Gains continued despite significant volatility amid electoral and fiscal uncertainty, and the 2012 close of the S&P 500 following QE3 was its third-highest ever, at 1,426.22 points. Many people hated the bull market.[22] On March 28, 2013, it closed above the closing high from 2007.[23] On April 10, 2013, it also closed above the intraday high from 2007.[24]

On May 3, 2013—more than 13 years since its first close above 1,500—the S&P 500 closed above 1,600 for the first time, at 1,614.42. This would be the first of three 100-point milestones in 2013: 1,600 on May 3, 2013;[25] 1,700 on August 1, 2013;[26] and 1,800 on November 22, 2013.[27] The S&P 500 closed out 2013 at a record high, finishing the December 31, 2013, trading day at 1,848.36.[28] On May 23, 2014, the index for the first time closed above 1,900, at 1,900.53.[29] On August 26, 2014, the index closed above 2,000 for the very first time,[30] and on December 22 the S&P 500 climbed to 2078, an all-time high.[31] The index closed on December 29 at 2,090.57 with a closing of 2,058.90 at the end of 2014.[32][33] This was a gain of 85% (in price return, and 105% in total return) for the five years 2010-2014. On February 17, 2015, the index first closed above 2,100, closing at 2,100.34. On February 25, 2015 it reached 2,119.59 during mid-day, and on the following day it closed at record high of 2,115.48.[34] On May 21, 2015, the index closed at 2,130.82, its high point for the year. At the close of 2015, the index hit 2,043.94, down 0.73% for the year.

Selection criteria[edit]

The components of the S&P 500 are selected by committee. This is similar to the Dow Jones Industrial Average, but different from others such as the Russell 1000, which are strictly rule-based. When considering the eligibility of a new addition, the committee assesses the company's merit using eight primary criteria: market capitalizationliquiditydomicilepublic floatsector classification, financial viability, length of time publicly traded and listing exchange.[5]

The committee selects the companies in the S&P 500 so they are representative of the industries in the United States economy. In order to be added to the index, a company must satisfy these liquidity-based size requirements:[5]

  • market capitalization is greater than or equal to US$5.3 billion
  • annual dollar value traded to float-adjusted market capitalization is greater than 1.0
  • minimum monthly trading volume of 250,000 shares in each of the six months leading up to the evaluation date.

The securities must be publicly listed on either the NYSE (including NYSE Arca or NYSE MKT) or NASDAQ (NASDAQ Global Select Market, NASDAQ Select Market or the NASDAQ Capital Market). Securities that are ineligible for inclusion in the index are limited partnershipsmaster limited partnershipsOTC bulletin board issuesclosed-end fundsETFsETNsroyalty truststracking stockspreferred stockunit trustsequity warrantsconvertible bondsinvestment trustsADRsADSs and MLP IT units.[5]

The index includes non-U.S. companies (27 as of December 23, 2013), both formerly U.S.-incorporated companies that have re-incorporated outside the United States, as well as firms that have never been incorporated in the United States.

Components[edit]

Versions[edit]

The "S&P 500" generally quoted is a price return index; there are also "total return" and "net total return" versions of the index. These versions differ in how dividends are accounted for. The price return version does not account for dividends; it only captures the changes in the prices of the index components. The total return version reflects the effects of dividend reinvestment. Finally, the net total return version reflects the effects of dividend reinvestment after the deduction of withholding tax.[35][36]

Weighting[edit]

The index has traditionally been capitalization-weighted; that is, movements in the prices of stocks with higher market capitalizations (the share price times the number of shares outstanding) have a greater impact on the value of the index than do companies with smaller market caps.[citation needed]

The index is now float weighted. That is, Standard & Poor's now calculates the market capitalization of each company relevant to the index using only the number of shares available for public trading (called the "float"). This transition was made in two steps, the first on March 18, 2005 and the second on September 16, 2005.[37]

Index maintenance[edit]

In order to keep the S&P 500 Index consistent over time, it is adjusted to capture corporate actions which affect market capitalization, such as additional share issuance, dividends and restructuring events such as mergers or spin-offs. Additionally, to remain indicative of the U.S. stock market, the constituent stocks are changed from time to time.[5] Between 1/1/2005 and 1/1/2015, 188 index components were replaced by other components.[38]

To prevent the value of the Index from changing merely as a result of corporate financial actions, all such actions affecting the market value of the Index require a divisor adjustment. Also, when a company is dropped and replaced by another with a different market capitalization, the divisor needs to be adjusted in such a way that the value of the S&P 500 Index remains constant. All divisor adjustments are made after the close of trading and after the calculation of the closing value of the S&P 500 Index. There is a large range of different corporate actions that can require the divisor to be adjusted. These are listed in the table below:[39]

Type of ActionDivisor Adjustment
Stock split (e.g. 2×1)No
Share issuanceYes
Share repurchaseYes
Special cash dividendYes
Company changeYes
Rights offeringYes
SpinoffsYes
MergersYes

Calculation[edit]

To calculate the value of the S&P 500 Index, the sum of the adjusted market capitalization of all 500 stocks is divided by a factor, usually referred to as the Divisor.[39][40] For example, if the total adjusted market cap of the 500 component stocks is US$13 trillion and the Divisor is set at 8.933 billion, then the S&P 500 Index value would be 1,455.28. Although the adjusted market capitalization of the entire index can be accessed from Standard & Poor's website,[41] the Divisor is considered to be proprietary to the firm. However, the Divisor's value is approximately 8.9 billion.[42]

The formula to calculate the S&P 500 Index value is:

 \text{Index Level} = {\sum \left({P_i} \cdot {Q_i}\right) \over Divisor}

where P is the price of each stock in the index and Q is the number of shares publicly available for each stock.

The divisor is adjusted in the case of stock issuance, spin-offs or similar structural changes, to ensure that such events do not in themselves alter the numerical value of the Index.[39]

Update frequency[edit]

The index value is updated every 15 seconds during trading sessions and is disseminated by Reuters America, Inc., a subsidiary of Thomson Reuters Corporation.[43]

Investing[edit]

Many index funds and exchange-traded funds attempt to replicate (before fees and expenses) the performance of the S&P 500 by holding the same stocks as the index, in the same proportions. Many other mutual funds are benchmarked to the S&P 500. Consequently, a company whose stock is added to the list of S&P 500 stocks may see its stock price rise, as index funds must purchase that company's stock in order to continue tracking the S&P 500 index. Mutual fund managers provide index funds that track the S&P 500, the first of which was The Vanguard Group's Vanguard 500 in 1976.[44]

In addition to investing in a mutual fund indexed to the S&P 500, investors may also purchase shares of an exchange-traded fund (ETF) which represents ownership in a portfolio of the equity securities that comprise the Standard & Poor's 500 Index. Exchange Traded Funds track the S&P 500 index and may be used to trade the index. Some S&P 500 ETFs are listed as follows.[45]

ETF SymbolETF NameFees, per year
IVViShares Core S&P 500bps
SPYSPDR S&P 50010.98 bps
VOOVanguard S&P 500bps

S&P 500 ETFs are available on the London Stock Exchange e.g. iShares S&P 500 (LSEIUSA) and Vanguard S&P 500 (LSEVUSA). There is also a Japanese fund tracking the index (TYO1547).

Investors may also invest in all the stocks of the S&P 500 directly, which is usually called index investing.

In the derivatives market, the Chicago Mercantile Exchange (CME) offers futures contracts (ticker symbols /SP for the full-sized contract and /ES for the E-mini contract that is one-fifth the size of /SP) that track the index and trade on the exchange floor in an open outcry auction, or on CME's Globex platform, and are the exchange's most popular product. Additionally, the Chicago Board Options Exchange (CBOE) offers options on the S&P 500 as well as S&P 500 ETFs, inverse ETFs and leveraged ETFs.

Market statistics[edit]

Milestones[edit]

On 11 October 2007, S&P index set a milestone with its all-time intraday high of 1,576.09.[46] On 28 March 2013, the S&P finally surpassed its closing high level of 1,565.15, recovering all its losses from the financial crisis.[46] On 2 March 2015, the S&P finally closed at a new all-time inflation-adjusted closing high, though it has yet to achieve a new all-time inflation-adjusted intraday high, both of which were set back in 2000.[47][48]

Annual returns[edit]

(total return) Calculation used for CAGR (Compound Annual Growth Rate, Annualized Return):

CAGR = ((Ending Value)/(Starting Value))∧(1/ (# of years)) - 1

The current CAGR is calculated at 10.47%.
