What it is
The Nasdaq Composite (ticker ^IXIC) is a capitalization-weighted stock index covering almost all companies listed on the Nasdaq exchange, launched February 5, 1971 at a base value of 100. It is heavily weighted toward technology, with Apple, Microsoft, Nvidia, Amazon, Meta, and Alphabet together regularly accounting for more than 40% of its total weight.
Why it matters lately
The Nasdaq Composite closed at a record high of 27,244.28 on September 22, 2026 (intraday record 27,288.79), its first intraday record since early June, as AI-driven chip stocks rallied (AMD's market cap topped $1 trillion) and retreating oil prices — on signs Iran could reopen the Strait of Hormuz — lifted broader risk appetite.
Asymmetric Analytics view
Inference (AA): The Nasdaq Composite is the graph's benchmark for US tech/AI equity risk appetite, linked to oil-shock and Fed-policy nodes.
