“NASDAQ-100”的意思、由来-开放百科全书

The NASDAQ-100 (^NDX^[1]) is a stock market index made up of 103 equity securities issued by 100 of the largest non-financial companies listed on the NASDAQ. It is a modified capitalization-weighted index. The stocks' weights in the index are based on their market capitalizations, with certain rules capping the influence of the largest components. It is based on exchange, and it is not an index of U.S.-based companies. It does not have any financial companies, since these were put in a separate index. Both of those criteria differentiate it from the Dow Jones Industrial Average, and the exclusion of financial companies distinguishes it from the S&P 500.

History

The NASDAQ-100 began on January 31, 1985 by the NASDAQ, trying to promote itself in the shadow of the New York Stock Exchange. It did so by creating two separate indices: this index, which consists of Industrial, Technology, Retail, Telecommunication, Biotechnology, Health Care, Transportation, Media and Service companies, and the NASDAQ Financial-100, which consists of banking companies, insurance firms, brokerage houses and mortgage companies. By creating these two indices, the NASDAQ hoped that options and futures contracts would be created on them, and mutual funds would adopt them as their benchmarks.{{CN|date=February 2018}}

The base price of the index was initially set at 250, but when it closed near 800 on December 31, 1993, the base was reset at 125 the following trading day, leaving the halved NASDAQ-100 price below that of the more commonly known NASDAQ Composite. The first annual adjustments were made in 1993 in advance of options on the index that would trade at the Chicago Board Options Exchange in 1994. Foreign companies were first admitted to the index in January 1998, but had higher standards to meet before they could be added. Those standards were relaxed in 2002, while standards for domestic firms were raised, ensuring that all companies met the same standards. The all-time highs for the index, set at the height of the Dot-Com Bubble in 2000, stand above the 4,700 level, while its recent bear market lows in 2002 revolving around the Early 2000s Recession, the September 11, 2001 Attacks and the subsequent Afghan War occurred below the 900 point level.{{CN|date=February 2018}}

After a gradual 5-year recovery to an intraday high of 2,239.51 on October 31, 2007, the highest reached since February 16, 2001, the index corrected below the 2,000 level in early 2008 amid the Late-2000s Recession, the United States Housing Bubble and the Global Financial Crisis of 2008. Panic focusing on the failure of the investment banking industry culminated in a loss of more than 10% on September 29, 2008, subsequently plunging the index firmly into bear market territory. The NASDAQ-100, with much of the broader market, experienced a Limit Down open on October 24 and reached a 6-year intraday low of 1,018 on November 20, 2008.{{CN|date=February 2018}}

Amid quantitative easing (QE) from the Federal Reserve and optimism that the financial crisis was ending, the index embarked on a volatile four-year climb higher, closing above 3,000 on May 15, 2013 for the first time since November 15, 2000. By October 18, 2013, with GOOG passing $1,000 per share for the first time, the index had made a closing high of 3,353.88 and intraday high of 3,355.63, its highest levels since the United States elections, 2000 and more than triple the 2008 low. At the close of 2015, the index closed at 4593.27, for a gain of 8.43% on the year.{{CN|date=February 2018}}

Record values

Investing

The NASDAQ-100 is often abbreviated as NDX in the derivatives markets. Its corresponding futures contracts are traded on the Chicago Mercantile Exchange. The regular futures are denoted by the Reuters Instrument Code ND, and the smaller E-mini version uses the code NQ. Both are among the most heavily traded futures at the exchange.{{CN|date=February 2018}}

The PowerShares QQQ exchange-traded fund, sponsored and overseen since March 21, 2007 by Invesco through PowerShares, trades under the ticker {{NASDAQ|QQQ}}. It is commonly referred to by its ticker or nickname, "the que's". It was formerly called NASDAQ-100 Trust Series 1. On December 1, 2004, it was moved from the American Stock Exchange where it had the symbol QQQ to the NASDAQ and given the new four-letter code QQQQ, sometimes called the "quad Qs" by traders. On March 23, 2011, Nasdaq changed its symbol back to QQQ.^[2]

In 2000, QQQ was the most actively traded security in the United States, and hit an all-time split adjusted intra-day trading high of $120.50 on March 24 of that year, but has since dropped to being within the top five after other stocks and ETFs such as the Standard & Poor's Depositary Receipts. As of August 2012, the fund was the third most actively traded exchange-traded product in the world.^[3] On July 17, 2007, the ETF closed above $50 for the first time since early 2001. After reaching a peak of $55.07 on October 31, 2007, the Qs succumbed to a wider financial crisis along with a decline in technology spending and plunged towards a November 21, 2008 intra-day low of $25.05. Since then, it gradually advanced to surpass its 2007 peak, despite some volatility. By October 18, 2013, it had passed and closed above $82 to reach its highest price levels since November 6–7, 2000 and highest value since September 29, 2000 when adjusted for splits and dividends.{{CN|date=February 2018}}

Standards

The NASDAQ has over the years put in place a series of stringent standards that companies must meet before being included in the index. Those standards include the following:

Additionally, since 2014, companies with multiple classes of stock are allowed to have multiple classes included in the index, provided they meet NASDAQ's criteria. Prior to 2014, companies were limited to one class of stock in the index (usually the one with the larger market capitalization).{{CN|date=February 2018}}

Yearly rebalancing and re-ranking

While the composition of the NASDAQ-100 changes in the case of delisting (such as transferring to another exchange, merging with another company, or declaring bankruptcy, and in a few cases, being delisted by NASDAQ for failing to meet listing requirements), the index is only rebalanced once a year, in December, when NASDAQ reviews its components, compares them with those not in the index, re-ranks all eligible companies and makes the appropriate adjustments.{{CN|date=February 2018}}

There are two tools the NASDAQ uses to determine the market values of companies for the annual review:

Those components that are in the top 100 of all eligible companies at the annual review are retained in the index. Those ranked 101 to 125 are retained only if they were in the top 100 of the previous year's annual review. If they fail to move into the top 100 in the following year's review, they are dropped. Those not ranked in the top 125, are dropped regardless of the previous year's rank.{{CN|date=February 2018}}

The index also drops a company if, at the end of two consecutive months, it fails to have an index weighting of at least one-tenth of a percent. This can occur at any time.{{CN|date=February 2018}} Companies that are dropped are replaced by those with the largest market value that are not already in the index. Anticipation of these changes can lead to changes in the stock prices of affected companies.{{CN|date=February 2018}}

The index publicly announces all changes, regardless of when they occur, via press releases at least five business days before the change takes place. The 2018 results of the re-ranking and rebalancing were announced on December 14, with the changes effective the morning of December 24, coinciding with the expiration of options on December 21.{{CN|date=February 2018}}

Differences from NASDAQ Composite index

The NASDAQ-100 is frequently confused with the Nasdaq Composite Index. The latter index (often referred to simply as "The Nasdaq") includes the stock of every company that is listed on NASDAQ (more than 3,000 altogether) and is quoted more frequently than the NASDAQ-100 in popular media.{{CN|date=February 2018}}

The NASDAQ-100 is a modified capitalization-weighted index. This particular methodology was created in 1998 in advance of the creation the NASDAQ-100 Index Trust, which holds portions of all NASDAQ-100 firms. The new methodology allowed NASDAQ to reduce the influence of the largest companies and to allow for more diversification. However, the weights of the stocks were not changed after that, which led to more problems. In May 2011, NASDAQ did a major rebalance of the index to bring it closer to market-cap weighting.{{CN|date=February 2018}}

Differences from other indices

In addition to its lack of financial companies, the Nasdaq-100 includes 12 stocks of 11 companies incorporated outside the United States. Although the S&P 500 Index includes non-U.S. companies, the Dow Jones Industrial Average has never included foreign companies.{{CN|date=February 2018}}

As of November 2018, the Nasdaq-100 has companies incorporated in the following foreign countries:

Additionally, the NASDAQ-100 is also the only index of the three that has a regularly scheduled re-ranking of its index each year (in December), ensuring that the largest non-financial companies on NASDAQ are accurately included.{{CN|date=February 2018}}

Related indices

In 2006, NASDAQ created a "farm team" index, the NASDAQ Q-50, representing the next fifty stocks in line to enter the NASDAQ-100. With some exceptions, most stocks that are added to the index come up through the Q-50. In 2011, NASDAQ created the NASDAQ-500 to track the 500 largest stocks on NASDAQ, and the NASDAQ-400, tracking those stocks not included in the NASDAQ-100.{{CN|date=February 2018}}

NASDAQ has also divided the 100 into two distinct sub-indices; the NASDAQ-100 Tech follows those components who service the tech sector, and the NASDAQ-100 Ex-Tech, which follows those components that are not considered tech companies. The latter index includes noted E-commerce companies Amazon.com and eBay, which are classified as retailers.{{CN|date=February 2018}}

Components

Historical components

As of December 2018, 471 companies have been components of the index. Of these, only four, Apple, Costco (through its merger in 1993 with Price Club, with Costco, as a separate entity, not becoming a component until at least 1989), Intel and PACCAR, have been components, continuously, since the first dissemination of the index in 1985. Two other current components, KLA-Tencor and Micron Technology, were also components when the index started, but were removed from the index over time for various reasons.^[4]
