Components, capitalization and weighting[edit]

With 23 component stocks,[2] including Hovnanian Enterprises Inc., Pulte Homes, Inc., Lennar Corp., and D.R. Horton, the ISE Homebuilders Index attempts to capture at least two-thirds of the entire homebuilding industry’s market capitalization.

Capitalization and weighting[edit]

Due to the non-uniform weight distribution across entire industries, an equal-weighted methodology or a "modified market capitalization-weighted" methodology is used to adjust the weighting of component stocks, and individual component weightings are limited to no more than 30% of the weight of the index (this requirement must be met continuously throughout the year).
