Finance is a field that deals with the study of investments. It includes the dynamics of assets and liabilities over time under conditions of different degrees of uncertainties and risks. Finance can also be defined as the science of money management. Market participants aim to price assets based on their risk level, fundamental value, and their expected rate of return. Finance can be broken into three sub-categories: public finance, corporate finance and personal finance.
Trade involves the transfer of goods or services from one person or entity to another, often in exchange for money. A system or network that allows trade is called a market.
Nothing in finance is more fatuous and harmful, in our opinion, than the firmly established attitude of common stock investors regarding questions of corporate management. That attitude is summed up in the phrase: "If you don't like the management, sell your stock." [...] The public owners seem to have abdicated all claim to control over the paid superintendents of their property.
Benjamin Graham, World Commodities and World Currencies (1944)
