Invesco Nasdaq Biotechnology 

The Invesco Nasdaq Biotechnology ETF (IBBQ) seeks to mirror the investment performance of the Nasdaq Biotechnology Index. To achieve this, the Fund generally dedicates at least 90% of its total capital to the securities that make up this benchmark index. The underlying Index itself is specifically designed to gauge the returns of biotechnology and pharmaceutical companies whose shares are publicly traded on the Nasdaq Stock Market. Both the ETF and its corresponding Index undergo a yearly review and update of their composition each December, and their weightings are adjusted quarterly in March, June, September, and December.
