ISE Biotechnology and Pharmaceuticals Index
The index attempts to capture at least two-thirds of the entire sector's capitalization. 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 25% at semi-annual reviews. Quarterly rebalancing events are used to “re-set” the weighting of each component so each component has an equal influence on the index performance.
The ISE Biotech and Pharmaceuticals Index is one of eight ISE industry indexes that also include: ISE Integrated Oil and Gas Index; ISE Oil and Gas Services; ISE U.S. Regional Banks; ISE Semiconductor; ISE Gold; ISE Homebuilders and ISE SINdex.
As of Nov. 1, 2007, there are 31 ISE index options listed.
