In depth
Derivatives allow exposure to an asset without owning it, which is what makes them efficient for hedging and dangerous for speculating: the same leverage that lets a hedger protect a large position with little capital lets a speculator lose more than they put up. In India, exchange-traded derivatives are futures and options on indices and single stocks, regulated by SEBI and guaranteed by a clearing corporation. Their purpose in a market is risk transfer — someone who does not want a risk pays someone willing to bear it. SEBI's own studies have repeatedly found that a large majority of individual traders in equity derivatives lose money, which is a documented fact worth knowing before treating this category as an opportunity.
Worked example
A Nifty futures contract with a lot size of 75 at an index level of 24,000 has a contract value of 75 x 24,000 = ₹18,00,000, controlled with roughly ₹1,00,000 of margin — about 18 times leverage.

This entry explains what “Derivative” means. It is not investment advice and not a recommendation to buy or sell any security. Any numbers above are illustrative, not live prices, and nothing here predicts price direction or rates a stock. Consider your own circumstances and consult a SEBI-registered investment adviser before acting.
