Derivatives are financial contracts whose value is dependent on an underlying asset. Common types of derivatives include forwards, futures, options, and swaps. Derivatives can be used to hedge risk, speculate on asset prices, or gain leverage. While derivatives provide benefits like hedging and market efficiency, they also carry high risks like counterparty risk and can enable speculation. Corporate finance deals with capital investment, financing, and liquidity management decisions to maximize shareholder value and profits. This includes capital budgeting, sourcing debt or equity, and ensuring sufficient working capital and cash flows.
