Symbol Classification within IEX Top 50 Symbols Midday Report and TOPS Viewer

IEX Trading Alert #2016 - 027

Please Route To: Trading and Trade Support

What you need to know:

*The top 50 symbols are selected from the top quartile of symbols by consolidated market volume (i.e., volume reported for a security by all exchanges and trade reporting facilities to a consolidated transaction reporting plan), then ranked by market share on IEX.

What is changing?

MSCI GICS is a four-tiered, hierarchical industry classification system for equity securities. IEX currently uses the "Sector" tier of GICS to organize symbols presented in the IEX Top 50 Symbols Midday Report and TOPS Viewer, which are publicly available resources intended for informational purposes only. Effective on Tuesday, July 5, IEX will begin to use the "Industry Groups" classification tier of GICS instead of the "Sector" classification tier.
