Why NDX Inclusion Matters
The NDX consists of 100 of the largest non-financial companies listed on the Nasdaq exchange. The index is rebalanced quarterly to ensure its constituents continue to meet eligibility requirements.
Inclusion in the Nasdaq-100 can be beneficial for companies. The index is tracked by hundreds of funds with billions of dollars in assets. Index funds, exchange-traded funds (ETFs), and other investment vehicles that track the NDX must buy shares of newly added companies when they rebalance their portfolios.
As a result, stocks added to the index often see higher trading activity and more buying in the short-term around the time of inclusion.
