In terms of a security, such as a stock or a bond, or equivalently to be long in a security, means the holder of the position owns the security and will profit if the price of the security goes up. Going long a security is the more conventional practice of investing.
The term is also used to describe a position that's maintained by your brokerage firm or bank on your behalf. For example, if your firm holds stocks for you in street name, you are said to be long on their books. Having a long position is the opposite of having a short position in a security.
