QQQ

QQQ is a string that can refer to multiple concepts. The most widely known reference is the ticker symbol QQQ for the Invesco QQQ Trust, an exchange-traded fund that seeks to track the NASDAQ-100 Index. The fund is designed to replicate the performance of the 100 largest non-financial companies listed on the NASDAQ, with a heavy emphasis on technology and growth-oriented names. It is one of the most actively traded ETFs, providing high liquidity for investors and traders. The fund was launched in 1999 and is managed by Invesco. Typical holdings include large-cap technology and internet-related companies such as Apple, Microsoft, Amazon, Nvidia, and Alphabet, though the exact holdings change with the quarterly rebalancing of the NASDAQ-100.

In other contexts, "qqq" is simply a sequence of three lowercase q letters. It is not associated with a formal standard or code outside of specific uses, and may appear as a placeholder, sample input, or a string in programming and data examples. As such, its meaning is usually determined by context rather than an established definition.

Because of its prominence in financial markets, the symbol QQQ is commonly used in financial news and analysis to denote the Invesco QQQ Trust ETF. Outside finance, the term "qqq" carries no fixed meaning and is typically interpreted based on the surrounding context.
