Going long is a term in investing that simply means that you want to buy a particular asset. The term is the opposite of going short, which is when you want to sell something.
Going Long in Investing
When you’re bullish on an instrument, you want to go long in expectation of the price to appreciate and selling it at a higher price, thus making a profit.
For example, if you buy a stock, then you’re going long that particular stock because you expect the price to increase in the future and it’s said that you are long or have a long position. You’re going long also when you buy a derivative like a CFD, a futures contract or an option.
