Investing is the process of allocating resources—usually savings—with the expectation of a future return over a given time frame. The range of assets in which one can invest and earn a return is a very wide one. This includes investing in endeavors, such as using money to start a business, or in assets, such as purchasing real estate with the intent of reselling it after at a higher price. The basic premise of investing is the expectation of income or price appreciation.
