Stock market index in the context of "Alphabet Inc."

A mutual fund is an investment fund that pools money from many investors to purchase securities. The term is typically used in the United States, Canada, and India, while similar structures across the globe include the SICAV in Europe ('investment company with variable capital'), and the open-ended investment company (OEIC) in the UK.

Mutual funds are often classified by their principal investments: money market funds, bond or fixed income funds, stock or equity funds, or hybrid funds. Funds may also be categorized as index funds, which are passively managed funds that track the performance of an index, such as a stock market index or bond market index, or actively managed funds, which seek to outperform stock market indices but generally charge higher fees. The primary structures of mutual funds are open-end funds, closed-end funds, and unit investment trusts.

Nokia Corporation is a Finnish multinational telecommunications, information technology, and consumer electronics corporation, originally established as a pulp mill in 1865. Nokia's main headquarters are in Espoo, Finland, in the Helsinki metropolitan area, but the company's actual roots are in the Tampere region of Pirkanmaa. In 2020, Nokia employed approximately 92,000 people across over 100 countries, did business in more than 130 countries, and reported annual revenues of around €23 billion. Nokia is a public limited company listed on the Nasdaq Helsinki and New York Stock Exchange. It was the world's 415th-largest company measured by 2016 revenues, according to the Fortune Global 500, having peaked at 85th place in 2009. It is a component of the Euro Stoxx 50 stock market index.

The company has operated in various industries over the past 150 years. It was founded as a pulp mill and had long been associated with rubber and cables, but since the 1990s has focused on large-scale telecommunications infrastructure, technology development, and licensing. Nokia made significant contributions to the mobile telephony industry, assisting in the development of the GSM, 3G, and LTE standards. For a decade beginning in 1998, Nokia was the largest worldwide vendor of mobile phones and smartphones. In the later 2000s, however, Nokia suffered from a series of poor management decisions and soon saw its share of the mobile phone market drop sharply.

S&P 500 (Standard and Poor's 500) is a stock market index tracking the stock performance of 500 leading companies listed on stock exchanges in the United States. It is one of the most commonly followed equity indices and includes approximately 80% of the total market capitalization of U.S. public companies, with an aggregate market cap of more than $57.401 trillion as of August 29, 2025.

The S&P 500 index is a public float weighted/capitalization-weighted index. The ten largest companies on the list of S&P 500 companies account for approximately 38% of the market capitalization of the index and the 50 largest components account for 60% of the index. As of September 2025, the 10 largest components are, in order of highest to lowest weighting: Nvidia (7.2%), Microsoft (6.3%), Apple (5.9%), Alphabet (5.0%, including both class A & C shares), Amazon (4.1%), Meta Platforms (3.2%), Broadcom (2.8%), Tesla (2.3%), Berkshire Hathaway (1.8%), and JPMorgan Chase (1.4%).

The Nikkei 225, or the Nikkei Stock Average (Japanese: 日経平均株価, Hepburn: Nikkei heikin kabuka), more commonly called the Nikkei or the Nikkei index (/ˈnɪkeɪ, ˈniː-, nɪˈkeɪ/), is a stock market index for the Tokyo Stock Exchange (TSE). It is a price-weighted index, operating in the Japanese Yen (JP¥), and its components are reviewed twice a year. The Nikkei 225 measures the performance of 225 highly capitalised and liquid publicly owned companies in Japan from a wide array of industry sectors. Since 2017, the index is calculated every five seconds. It was originally launched by the Tokyo Stock Exchange in 1950, and was taken over by the Nihon Keizai Shimbun (The Nikkei) newspaper in 1970, when the Tokyo Exchange switched to the Tokyo Stock Price Index (TOPIX), which is weighed by market capitalisation rather than stock prices.

The Tokyo Stock Price Index (東証株価指数, Tōshō Kabuka shisū), commonly known as the TOPIX, is an important stock market index for the Tokyo Stock Exchange (TSE) in Japan, along with the Nikkei 225. The TOPIX tracks the entire market of domestic companies and covers most stocks in the Prime market and some stocks in the Standard market. It is calculated and published by the TSE. As of January 2025, there are planned to be 1,716 companies listed on the TSE, since about 400 stocks with low liquidity were phased out after the TSE reform in 2022.

The index transitioned from a system where a company's weighting is based on the total number of shares outstanding to a weighting based on the number of shares available for trading (called the free float). This transition started in October 2005 and was completed in June 2006. Although the change is a technicality, it had a significant effect on the weighting of many companies in the index, because many companies in Japan hold a significant number of shares of their business partners as a part of intricate business alliances, and such shares are no longer included in calculating the weight of companies in the index.

The Dow Jones Industrial Average (DJIA), Dow Jones, or simply the Dow (/ˈdaʊ/), is a stock market index of 30 prominent companies listed on stock exchanges in the United States.

The DJIA is one of the oldest and most commonly followed equity indices. It is price-weighted, unlike other common indices such as the Nasdaq Composite or S&P 500, which use market capitalization. The primary pitfall of this approach is that a stock's price—not the size of the company—determines its relative importance in the index. For example, as of March 2025, Goldman Sachs represented the largest component of the index with a market capitalization of ~$167B. In contrast, Apple's market capitalization was ~$3.3T at the time, but it fell outside the top 10 components in the index.
