Go Long
Go long.
When you go long, you buy a security or other financial product that you intend to hold for a period of time or one that you expect to increase in value so that you can sell it at a profit.
For example, if you're buying and selling options or futures contracts, you go long when you enter a contract to buy the underlying instrument. In the case of stock, you go long when you buy shares to hold in your portfolio, at least for the next term.
