NYSE Arca Biotechnology Index
The NYSE Arca Biotechnology Index (BTK) is an equal dollar weighted index designed to measure the performance of a cross section of companies in the biotechnology industry that are primarily involved in the use of biological processes to develop products or provide services. Such processes include, but are not limited to, recombinant DNA technology, molecular biology, genetic engineering, monoclonal antibody-based technology, lipid/liposome technology, and genomics. The BTK Index was established with a benchmark value of 200.00 on October 18, 1991. The BTK Index is rebalanced quarterly based on closing prices on the third Friday in January, April, July & October to ensure that each component stock continues to represent approximately equal weight in the index.
