The **Nasdaq Composite** is a prominent stock market index that tracks the performance of over 3,000 common stocks listed exclusively on the Nasdaq Stock Market, making it one of the broadest and most widely followed indices in the United States[1][2][5]. Established on February 1, 1971, the index offers a comprehensive snapshot of the market, especially emphasizing the technology sector, which constitutes the largest share of its composition[2][6]. It is capitalization-weighted, meaning companies with larger market capitalizations, such as tech giants Apple, Meta, and Microsoft, have a greater impact on the index’s value[1][2][3]. The Nasdaq Composite’s unique focus on technology and growth-oriented companies distinguishes it from other major indices like the Dow Jones Industrial Average or the S&P 500. This emphasis reflects the index’s role as a barometer for innovation-driven sectors, including information technology, biotechnology, and telecommunications[2][7]. It includes a wide variety of eligible securities such as common stocks, American depositary receipts (ADRs), real estate investment trusts (REITs), and tracking stocks, but excludes derivatives like preferred stocks and ETFs[2][4][6]. Over its history, the Nasdaq Composite has become a critical benchmark for investors and fund managers seeking exposure to high-growth companies and technology trends. While investors cannot directly purchase the index, they can invest in mutual funds and ETFs designed to track its performance, such as Fidelity’s ONEQ and Invesco’s QQQ ETF, the latter tracking the closely related Nasdaq-100 index[3][2]. The index’s value fluctuates daily based on the market performance of its constituents, and it serves as a vital tool for measuring the health of the tech sector and broader market sentiment. Currently, the Nasdaq Composite remains a dynamic and influential index, with a market value exceeding 22,000 points as of late 202
