Dow Jones Industrial Average in the context of "Capitalization-weighted index"

International Business Machines Corporation (using the trademark IBM), nicknamed Big Blue, is an American multinational technology company headquartered in Armonk, New York, and present in over 175 countries. It is a publicly traded company and one of the 30 companies in the Dow Jones Industrial Average. IBM is the largest industrial research organization in the world, with 19 research facilities across a dozen countries; for 29 consecutive years, from 1993 to 2021, it held the record for most annual U.S. patents generated by a business.

IBM was founded in 1911 as the Computing-Tabulating-Recording Company (CTR), a holding company of manufacturers of record-keeping and measuring systems. It was renamed "International Business Machines" in 1924 and soon became the leading manufacturer of punch-card tabulating systems. During the 1960s and 1970s, the IBM mainframe, exemplified by the System/360 and its successors, was the world's dominant computing platform, with the company producing 80 percent of computers in the U.S. and 70 percent of computers worldwide. Embracing both business and scientific computing, System/360 was the first family of computers designed to cover a complete range of applications from small to large.

The Dow Jones Transportation Average, (DJTA, also called the "Dow Jones Transports"), index ticker symbol DJT is a U.S. stock market index from S&P Dow Jones Indices of the transportation sector, and is the most widely recognized gauge of the American transportation sector. It is the oldest stock index still in use, being in use longer than its better-known relative, the Dow Jones Industrial Average (DJIA).

In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of the Dow Jones Industrial Average.

A time series is very frequently plotted via a run chart (which is a temporal line chart). Time series are used in statistics, actuarial science, signal processing, pattern recognition, econometrics, mathematical finance, weather forecasting, earthquake prediction, electroencephalography, control engineering, astronomy, communications engineering, and largely in any domain of applied science and engineering which involves temporal measurements.

In finance, a stock index, or stock market index, is an index that measures the performance of a stock market, or of a subset of a stock market. It helps investors compare current stock price levels with past prices to calculate market performance.

Two of the primary criteria of an index are that it is investable and transparent: The methods of its construction are specified. Investors may be able to invest in a stock market index by buying an index fund, which is structured as either a mutual fund or an exchange-traded fund, and "tracks" an index. The difference between an index fund's performance and the index, if any, is called tracking error.

The bankruptcy of Lehman Brothers, also known as the Crash of '08 and the Lehman Shock, on September 15, 2008, was the climax of the subprime mortgage crisis. After the financial services firm was notified of a pending credit downgrade due to its heavy position in subprime mortgages, the Federal Reserve summoned several banks to negotiate financing for its reorganization. These discussions failed, and Lehman filed a Chapter 11 petition that remains the largest bankruptcy filing in U.S. history, involving more than US$600 billion in assets.

The bankruptcy triggered a 4.5% one-day drop in the Dow Jones Industrial Average, then the largest decline since the attacks of September 11, 2001. It shook confidence in the government's ability to manage the crisis and prompted a general financial panic. Money market mutual funds, a key source of credit, saw mass withdrawal demands to avoid losses, and the interbank lending market tightened, threatening banks with imminent failure. The government and the Federal Reserve system responded with several emergency measures to contain the panic.

The US bear market of 2007–2009 was a bear market that lasted from October 9, 2007 to March 9, 2009, encompassing the 2008 financial crisis. The S&P 500 lost approximately 50% of its value, but the duration of the bear market was just below average.

The bear market was confirmed in June 2008 when the Dow Jones Industrial Average (DJIA) had fallen 20% from its October 11, 2007 high. This followed the bull market of 2002–07 and was followed by the bull market of 2009–2020.
