The Nairobi Securities Exchange (NSE), established in 1954 as Nairobi Stock Exchange, is the leading stock exchange in East Africa offering world class trading facilities for both its local and foreign investors looking to gain exposure to the country’s rising economy. The bourse is based in Nairobi, the capital of Kenya – one of the fastest-growing economies in Sub-Saharan Africa. The NSE operates under the jurisdiction of the Capital Markets Authority of Kenya, and is governed by an 11-member board of directors. In 2014, consequent to its successful IPO to raise Ksh 627 million, the NSE demutualized and became listed on the main board of its own exchange.
In 2008, in order to provide investors with a comprehensive measure of the performance of the market, the NSE launched the NSE All-Share Index (NASI). The NASI is a market capitalization-weighted index, with a base value of 100, consisting of all listed securities, effectively making it the benchmark index for the Kenyan stock market. In 2011, together with FTSE International, the NSE introduced the FTSE NSE Kenya 15 and FTSE NSE Kenya 25 indices which are designed for the creation of index tracking funds and derivative products, and as performance benchmarks while ensuring their investability. The NSE 25 Share Index measures the top 25 companies.
