A speculator is an individual or entity that engages in the practice of buying and selling assets, such as stocks, commodities, or real estate, with the intention of profiting from fluctuations in their prices. Unlike investors who typically focus on long-term value, speculators often seek to capitalize on short-term market movements and trends. This approach can involve a higher level of risk, as speculators may make decisions based on market sentiment or trends rather than fundamental analysis.
