Going long vs going short: Understanding trading positions
When you trade financial markets, every position you take reflects a view on price direction. The fundamental choice is straightforward: do you expect prices to rise, or do you expect them to fall? This is the core distinction when comparing going long vs going short.

Understanding these two approaches forms the foundation of market participation. Whether you trade shares, currencies, commodities or indices, the mechanics of long and short positions remain consistent. This guide explains how each works, compares their characteristics and outlines the risks you should understand before using either approach.

What does going long mean?
Going long simply means buying an asset with the expectation that its price will rise. When you go long, you purchase first and sell later. Your profit comes from the difference between your buying price and your selling price, assuming the market moves in your favour.
This is the most intuitive form of trading. It mirrors how most people think about investing: buy something, hold it and sell it at a higher price. When you buy shares in a company through a stockbroker, you are taking a long position.
The logic is direct. If you buy 100 shares at £10 each and later sell them at £15 each, you make £500 before costs. If the price falls to £7, you lose £300. Your maximum loss when going long is limited to your initial investment, though that still represents a complete loss of the capital you committed.
How long positions work in practice
Consider a practical example. You believe a company’s share price will increase following a strong earnings report. You buy 200 shares at £25 each, committing £5,000.
Three scenarios might unfold:
Scenario one: The price rises to £32. You sell for £6,400, making a £1,400 profit before dealing costs.
Scenario two: The price stays flat. You sell at £25, breaking even minus any transaction fees.
Scenario three: The price drops to £18. You sell for £3,600, losing £1,400.
In the worst case, if the company went bankrupt and shares became worthless, you would lose your entire £5,000 investment. This represents the maximum possible loss on a long position in shares.
The mechanics are similar across asset classes. Going long on gold means buying gold (or a gold-tracking instrument) expecting prices to rise. Going long on a currency pair means buying the base currency against the quote currency.
What does going short mean?
Going short means selling an asset you do not currently own, with the intention of buying it back later at a lower price. Short sellers profit when prices fall. This reverses the traditional sequence: you sell first, then buy later.
Short selling allows traders to potentially profit from declining markets. It also serves other purposes, including hedging existing long positions against potential falls.
The concept can seem counterintuitive at first. How can you sell something you do not own? The answer involves borrowing.
How short selling works step by step
Traditional short selling in shares follows this sequence:
Step one: You borrow shares from a broker or another investor who owns them. There is usually a fee for this borrowing arrangement.
Step two: You immediately sell those borrowed shares at the current market price.
Step three: You wait for the price to move. If it falls as you anticipated, you proceed to the next step.
Step four: You buy back the same number of shares at the new, lower price.
Step five: You return the shares to the lender and keep the difference as profit, minus borrowing costs.
Example: You believe a company’s shares, currently trading at £50, will decline. You borrow and sell 100 shares, receiving £5,000. The price falls to £35. You buy back 100 shares for £3,500, return them to the lender, and keep £1,500 as profit before costs.
But here is the critical distinction. If the price rises instead, your losses can theoretically be unlimited. Share prices can only fall to zero, but there is no ceiling on how high they can climb.
Key differences between long and short positions
The table below summarises the fundamental differences between going short vs going long:
Characteristic | Long position | Short position |
|---|---|---|
Market view | Bullish (expecting price rise) | Bearish (expecting price fall) |
Sequence | Buy first, sell later | Sell first, buy later |
Profit from | Price increase | Price decrease |
Maximum profit | Theoretically unlimited | Limited to 100% (if price falls to zero) |
Maximum loss | Limited to initial investment | Theoretically unlimited |
Borrowing required | No (for direct ownership) | Yes (must borrow asset to sell) |
Ongoing costs | Minimal (holding costs vary) | Borrowing fees accumulate over time |
Risk profiles compared
The asymmetry in risk profiles between long and short positions deserves careful attention.
When you go long, your maximum loss is capped. If you invest £1,000 in shares, you cannot lose more than £1,000. The shares cannot fall below zero.
When you go short, your potential loss has no theoretical limit. If you short a stock at £20 and it rises to £200, your loss is nine times your initial position size. Stories of dramatic short squeezes demonstrate this risk in practice, where prices spike rapidly as short sellers rush to buy back shares, pushing prices even higher.
This unlimited loss potential means short selling requires careful risk management. Many traders use stop-loss orders to close positions automatically if prices move against them by a predetermined amount. However, in fast-moving markets, prices can gap past stop levels, resulting in larger losses than expected.
When traders might consider each approach
Long positions suit traders who:
Believe an asset’s price will rise
Want straightforward ownership of an asset
Prefer limited downside risk relative to potential gains
Are comfortable with a buy-and-hold approach
Short positions might be considered by traders who:
Believe an asset’s price will fall
Want to hedge existing long positions
Understand and accept the unlimited loss potential
Can monitor positions closely and manage risk actively
Neither approach is inherently superior. Each reflects a different market view and carries its own risk characteristics. Past price movements do not indicate how prices will move in the future.
Understanding the risks of both strategies
Both long and short positions carry material risks. Understanding these risks before you trade is essential.
Risks of long positions
Long positions are often perceived as less risky because losses are capped. However, significant risks remain:
Capital loss: You can lose your entire investment. If a company fails or an asset becomes worthless, you lose 100% of the capital committed.
Opportunity cost: Capital tied up in a losing position cannot be deployed elsewhere.
Timing risk: Even if your market view is correct over time, short-term movements can test your resolve and capital.
Concentration risk: Large positions in single assets amplify these dangers.
Market-wide declines: During broad market selloffs, most long positions lose value simultaneously.
Risks of short positions
Short positions carry all the risks above, plus several additional concerns:
Unlimited loss potential: This cannot be overstated. A short position can lose more than your initial capital if prices rise significantly.
Borrowing costs: Fees for borrowing shares accumulate over time, eating into potential profits or adding to losses.
Dividend liability: If you are short when a dividend is paid, you must pay that dividend to the share lender.
Short squeeze risk: If many traders are short the same asset and prices begin rising, the rush to close positions can drive prices sharply higher.
Recall risk: The lender may demand their shares back at an inconvenient time, forcing you to close your position.
Margin requirements: Short positions typically require maintaining margin. If your position moves against you, you may face margin calls demanding additional funds.
Long and short positions with derivatives
Many retail traders do not engage in traditional short selling through borrowing shares. Instead, they use derivative products that allow both long and short positions without owning or borrowing the underlying asset.
CFDs and spread betting explained
Contracts for difference (CFDs) and spread betting are two common derivatives used by UK retail traders to take long or short positions.
CFDs are leveraged products that track the price of an underlying asset. You never own the asset itself. Instead, you enter a contract with a provider to exchange the difference in price between opening and closing the position.
To go long with a CFD, you open a buy position. If the price rises, you profit. If it falls, you lose.
To go short with a CFD, you open a sell position. If the price falls, you profit. If it rises, you lose.
Spread betting works similarly but is structured as a bet on price movement rather than a contract. In the UK, spread betting profits are generally free from capital gains tax (CGT) under current rules, though tax treatment depends on individual circumstances and may change. Spread betting is typically treated by HMRC as exempt from CGT for many individuals, but tax treatment depends on your circumstances and may change; this is not tax advice.
CFDs are complex instruments and come with a high risk of losing money rapidly due to leverage. Approximately 80% of retail investor accounts lose money when trading CFDs, according to Financial Conduct Authority data. You should consider whether you understand how CFDs work and whether you can afford to take the high risk of losing your money.
Key features of derivatives for long and short trading:
Feature | Implication |
|---|---|
Leverage | Smaller capital required, but losses amplified |
No ownership | You do not own the underlying asset |
Both directions | Can go long or short equally easily |
Overnight costs | Positions held overnight incur financing charges |
Counterparty risk | Your profit depends on the provider meeting obligations |
With derivatives, the market exposure on short positions can be theoretically unlimited, and losses can exceed your initial margin/deposit; however, UK retail CFD clients generally have negative balance protection, which limits losses to the funds in your account. Leverage makes this risk more acute because small adverse price movements can quickly erode your margin and trigger forced closure of positions.
Summary: Choosing between long and short
Understanding the mechanics of going long vs going short is fundamental to market participation. Neither approach guarantees profits. Both can result in significant losses.
Long positions offer a straightforward way to benefit from rising prices, with losses limited to your initial investment. Short positions allow you to potentially profit from falling prices, but carry theoretically unlimited loss potential and additional costs and complexities.
Derivative products like CFDs and spread betting enable both long and short positions without owning underlying assets. However, leverage amplifies both gains and losses, and you can lose more than your deposit.
Key points to remember:
Going long means buying to profit from rising prices.
Going short means selling borrowed assets to profit from falling prices.
Long positions have limited downside; short positions do not.
Derivatives enable both directions but add leverage risk.
Past price movements do not predict future results.
Both strategies can result in substantial losses.
Before trading, consider your financial situation, risk tolerance and whether you understand the products involved. If you are unsure, seek guidance from a qualified financial adviser.

Going long on a stock means buying shares with the expectation that the price will rise. You purchase first and sell later. Your profit comes from selling at a higher price than you paid. Your maximum loss is limited to the amount you invested, as share prices cannot fall below zero.
Short selling involves borrowing shares from a broker or another investor, selling them immediately at the current price, then buying them back later at a hopefully lower price to return to the lender. You profit from the price difference if the price falls. However, if the price rises, your losses can theoretically be unlimited.
Short positions carry higher risk because losses are theoretically unlimited. When you go long, your maximum loss is your initial investment. When you go short, prices can rise indefinitely, meaning potential losses have no ceiling. Short positions also involve borrowing costs, dividend liability, and the risk of short squeezes.
Yes, traders can hold both long and short positions simultaneously. This might involve being long one asset while short another, or even being long and short the same asset in different accounts or through different instruments. This is sometimes done for hedging purposes, though it involves additional complexity and costs.
