In financial terms, a deal refers to an agreement between two parties to buy or sell a particular asset at a specified price and time. It can involve different types of financial instruments, such as stocks, bonds, options, futures, or currencies, among others. Deals are usually executed through a broker or a trading platform, and they can be either long-term or short-term, depending on the investment strategy and the goals of the parties involved. Deals can also involve complex financial structures, such as mergers and acquisitions, leveraged buyouts, or securitization, among others.
