Option

Options provide asymmetric risk/reward profiles - limited downside (premium paid) with potentially unlimited upside. Call options give the right to buy, put options the right to sell. Options can be used for speculation, hedging, or income generation through premium collection. American-style options can be exercised anytime before expiration, while European-style only at expiration. Option pricing depends on underlying asset price, strike price, time to expiration, volatility, interest rates, and dividends. Options exist on stocks, indices, commodities, currencies, and futures. They enable sophisticated strategies like spreads, straddles, and collars for various market outlooks. Options provide leverage and flexibility but require understanding of time decay and volatility effects.
