Term: Long

Being "long" a stock, or holding a "long position," simply means you own it. You bought shares (or a contract) outright, and you now profit if the price rises and lose if the price falls. It is the most basic position in trading — the opposite of being "short," where you profit when the price falls instead.

Going long works the way most people already think of investing: you pay money to buy an asset at today's price, hold it for some period of time (seconds, for a day trader, or years, for a long-term investor), and then sell it. If the sale price is higher than what you paid, the difference is your profit; if it's lower, that difference is your loss. Your maximum loss on a long position is capped at what you paid, since a stock price can't fall below zero, but your potential gain is theoretically unlimited.

The nuance beginners often miss is that "long" describes your exposure, not your timeframe. A trader who buys a stock and sells it ninety seconds later is just as "long" during that window as someone who buys and holds for ten years. The word tells you which direction you need the price to move to make money — up — not how long you intend to hold it. People sometimes also say "I'm long on tech" or "I'm long this idea" to mean they believe something will do well, even outside of an actual position, but in trading specifically it refers to the position itself.

It's also worth separating "going long" from "buying." You buy to go long, but you can also buy to close out a short position (buying back shares you had borrowed and sold). So the direction of the trade — buy or sell — doesn't by itself tell you whether a position is long or short; what matters is whether, after the trade, you own the asset (long) or owe it (short).
