About the NYSE Index Family
NYSE U.S. 100 Index (NY.ID):
The U.S. 100 Index reflects the performance of the 100 NYSE-listed U.S. companies with the largest market capitalization. Companies included in the index represent over 47% of the market capitalization of the entire U.S. market.

NYSE International 100 Index (NYI.ID):The International 100 Index reflects the performance of the 100 NYSE-listed non-US companies with the largest market capitalization.  It is designed to assist investors seeking to track the largest companies outside the U.S. market.

NYSE TMT Index (NYY.ID): The TMT Index tracks the top 100 NYSE-listed technology, media and telecom stocks.  Approximately the same size as Nasdaq, the NYSE TMT Index is the first tool to track the global TMT market with all components priced on the NYSE during U.S. trading hours.

NYSE World Leaders Index (NYL.ID): The World Leaders Index combines the U.S. 100 and International 100 Indexes to create a well-diversified group of NYSE-listed companies that represent 17 countries and all 10 industry sectors according to the Industry Classification Benchmark. 

Methodology
The entire index universe is ranked in descending order by unadjusted market capitalization. Prior components with size ranks of 80 or higher remain in the index while prior components ranked below 120 in size are removed from the index. Beginning with the highest-ranked component, any non-component stock ranked 80 or higher on the selection list is added to the index. The new stock replaces the lowest-ranked stock remaining in the index, if the index would have more than 100 components when it is added.

*For the NYSE TMT Index, cap sector weights are set for technology, media and telecommunications at no more than 40% so that no one sector dominates the index. Also cap sub-industry weights are set at no more than 20% so that one sub-group does not dominate the index.

*For the NYSE World Leaders Index, tracking for the components and performance of the NYSE US 100 Index and NYSE International 100 Index are combined and component weights are based on float-adjusted market-caps for the combined index.

The company additions and/or deletions listed above are not an assessment of the company’s prospects, potential or investment value.
