The term long position describes what an investor has purchased when they buy a security or derivative with the expectation that it will rise in value.
Investors can establish long positions in securities such as stocks, mutual funds or currencies, or even in derivatives such as options and futures. Holding a long position is a bullish view. A long position is the opposite of a short position (also known simply as "short").
The term long position is often used In the context of buying an options contract. The trader can hold either a long call or a long put option, depending on the outlook for the underlying asset of the option contract.
For example, an investor who hopes to benefit from an upward price movement in an asset will "go long" on a call option. The call gives the holder the option to buy the underlying asset at a certain price. Conversely, an investor who expects an asset’s price to fall will be long on a put option—and maintain the right to sell the asset at a certain price.

Going long on a stock or bond is the more conventional investing practice in the capital markets, especially for retail investors. With a long-position investment, the investor purchases an asset and owns it with the expectation that the price is going to rise. This investor normally has no plan to sell the security in the near future. In reference to holding equities, which have an inherent bias to rise, long can refer to a measurement of time as well as bullish intent.
