What Is a Long Position? #
A long position simply means buying an asset with the expectation that its price will rise, so it can later be sold at a higher price.
This is the most natural and familiar way of trading: buy low, sell high. If you buy shares of a company, a cryptocurrency, or an ounce of gold expecting the price to go up, you are “going long.”
What Is a Short Position? #
A short position is the opposite: it means selling an asset first, with the expectation that its price will fall, so it can later be bought back at a lower price.
At first glance this sounds strange — how can you sell something you don’t already own? This is where the concept of short selling comes in.
How Short Selling Actually Works #
Short selling relies on borrowing.
- The trader borrows the asset (for example, shares of a stock) from someone who owns it, usually through a broker.
- The trader immediately sells the borrowed asset at the current market price.
- If the price falls as expected, the trader buys the same asset back at the lower price.
- The trader returns the borrowed asset to its owner, and keeps the difference between the sell price and the buy-back price as profit.
If the price rises instead of falling, the trader still has to buy back the asset to return it — but now at a higher price, resulting in a loss.
Long vs. Short: The Core Difference #
The two are mirror images of each other:
- Long: buy first, sell later → profits when price goes up
- Short: sell first, buy back later → profits when price goes down
Both are simply ways of expressing an opinion on the future direction of price. Neither one is inherently “better” — they are tools suited to different market expectations.
Why Some Markets Allow Shorting and Others Don’t #
Short selling requires that the asset can actually be borrowed. This is not possible or not permitted in every market.
- Forex and cryptocurrency spot/derivatives markets: Shorting is generally straightforward, since currencies and many crypto exchanges support borrowing or use derivative structures (like perpetual futures) that make going short as easy as going long.
- Stock markets: Shorting is usually possible but depends on the availability of shares to borrow, and is often subject to specific broker rules and regulations.
- Some emerging or less-developed markets: Short selling may be restricted or entirely unavailable, often to reduce excessive speculation or protect market stability. The Tehran Stock Exchange, for example, does not generally allow the kind of short selling seen in developed markets, which is one of the key structural differences traders need to account for when designing strategies for it.
This is an important practical point: a trading strategy that relies on taking short positions simply cannot be applied in a market where shorting isn’t available — the strategy would need to be redesigned to only use long positions, or to substitute other risk-management tools instead.
Conclusion #
Long and short positions represent the two basic directions a trade can take: buying in anticipation of a price rise, or selling first — through borrowing — in anticipation of a price fall. While the logic is symmetrical, not every market structurally supports both directions, which is a key factor to consider before designing any trading strategy.
One-Sentence #
A long position profits when price rises, a short position profits when price falls through borrowing and selling first, and not all markets allow short selling.
