Financial speculation, involves the buying, holding, selling,
and short-selling of stocks, bonds, commodities, currencies,
collectibles, real estate, derivatives, or any valuable financial
instrument to profit from fluctuations in its price as opposed
to buying it for use or for income via methods such as dividends
or interest. Speculation or agiotage represents one of four
market roles in Western financial markets, distinct from hedging,
long- or short-term investing, and arbitrage.
