Everything on Index Structure

The Nasdaq 100 is a venue-based index, meaning its composition is determined by which companies choose to list on the Nasdaq exchange, rather than a fixed sector or market cap definition. This creates a dynamic but potentially unstable index composition that depends on the exchange's brand appeal.

Impact: Investors must monitor the exchange's ability to attract top-tier companies, as a loss of key listings could significantly alter the index's risk-return profile.
