The major participants in derivative markets are hedgers, speculators, and arbitrageurs. Hedgers use derivatives to reduce risk associated with price movements of an asset. Speculators buy and sell derivatives to make profits by betting on future price movements, taking on increased risk. Arbitrageurs take advantage of price discrepancies in different markets by simultaneously buying and selling assets, engaging in virtually riskless transactions that enhance price stability. Together these different types of traders provide liquidity and help the derivatives market function efficiently.
