The cash-settled proprietary ISE 250 Index (IXZ) tracks the top 250 U.S. stocks trading on NYSE, AMEX and NASDAQ. Companies in the index represent an adjusted market capitalization of about $9 trillion.[1]
Similar to the ISE's other broad-based, pan-industry indexes, ISE 50 Index and ISE 100 Index, the ISE 250 is a capitalization-weighted index. However, it does not include stocks on the basis of market capitalization.
The Index is calculated and maintained by Standard & Poor’s (S&P) based on a methodology developed by ISE in consultation with S&P.
As of Nov. 1, 2007, there are 31 ISE index options listed.
