Derivatives are financial contracts whose value is derived from an underlying asset such as stocks, commodities, currencies, or indices.
Derivatives are widely used in financial markets for hedging risk, speculation, and arbitrage. Their value depends on the price movement of an underlying asset like shares, gold, oil, or currency.
Common derivatives are traded on exchanges like the National Stock Exchange and Bombay Stock Exchange, under regulation of the Securities and Exchange Board of India.
