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, rather than reducing risk. Arbitrageurs take advantage of price discrepancies in different markets by simultaneously buying and selling assets to generate riskless profits. Together these different types of traders provide liquidity and help stabilize prices in the derivatives market.
