How is the Index Different From Other Indices?

 

The NASDAQ Clean Edge Liquid Series U.S. Index is a pure play index (not diluted).

 

A number of differences exist between our index and others based on the selection criteria and weighting methodology applied. Our goal is to track the industry and develop an index that we believe best reflects the opportunity for U.S.-listed clean-energy companies and acts as a benchmark for the emerging clean-energy sector.

 

NASDAQ Clean Edge index constituents must pass a rigorous screening test:

  • Listed on NASDAQ, NYSE or Amex
  • Minimum market cap of $150 million
  • Average daily trading volume of at least 100-thousand shares year-to-date
  • Minimum closing price of $1.00
  • Demonstrated ability to capture the growth potential of the clean-energy sector
