The NIFTY 50 index is National Stock Exchange of India's benchmark stock market index for Indian equity market. Nifty is owned and managed by India Index Services and Products (IISL), which is a wholly owned subsidiary of the NSE Strategic Investment Corporation Limited. IISL had a marketing and licensing agreement with Standard & Poor's for co-branding equity indices until 2013. NIFTY 50 Index has shaped up as a largest single financial product in India, with an ecosystem comprising: exchange traded funds (onshore and offshore), exchange-traded futures and options (at NSE in India and at SGX and CME abroad), other index funds and OTC derivatives (mostly offshore). The NIFTY 50 covers 22 sectors of the Indian economy and offers investment managers exposure to the Indian market in one portfolio. During 2008-12, Nifty 50 Index share of NSE market capitalisation fell from 65% to 29%〔(CNX Nifty loses importance to sectoral indices )〕 due to the rise of sectoral indices like CNX Bank, CNX IT, CNX Mid Cap, etc. The CNX Nifty 50 Index gives 29.70% weightage to financial services, 0.73% weightage to industrial manufacturing and nil weightage to agricultural sector.〔(Sectoral weightage of CNX Nifty 50 Index )〕 The NIFTY 50 index is a free float market capitalisation weighted index. The index was initially calculated on full market capitalisation methodology. From June 26, 2009, the computation was changed to free float methodology. The base period for the CNX Nifty index is November 3, 1995, which marked the completion of one year of operations of ''National Stock Exchange Equity Market Segment''. The base value of the index has been set at 1000, and a base capital of Rs 2.06 trillion.〔(CNX Nifty Index Methodology )〕 ==History== Formerly known as the S&P CNX Nifty Index, it was renamed in 2013 with the expiration of agreement between IISL and Standard and Poor’s Financial Service on 31st Jan 2013. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「CNX Nifty」の詳細全文を読む スポンサード リンク
