The new contracts include futures on both the DJIA and the S&P 500, and options on the S&P 500 . </P> <P> On 3 May 2012, the National Stock exchange launched derivative contracts (futures and options) on FTSE 100, the widely tracked index of the UK equity stock market . This was the first of its kind of an index of the UK equity stock market launched in India .
