Long & Short

What Do Long and Short Mean?

Long and short are the two fundamental trading directions in financial markets. They describe whether a trader is betting on rising or falling prices.

Long (Buying)

A long position is established when a trader buys a financial instrument because they expect the price to rise. The profit comes from the difference between the lower purchase price and the higher selling price.

Example: A trader buys an E-Mini S&P 500 future at 5,000 points and sells it at 5,020 points. The profit is 20 points multiplied by the contract value.

Short (Selling)

A short position is established when a trader sells an instrument they do not own because they expect the price to fall. The profit comes from the difference between the higher selling price and the lower buyback price.

Example: A trader sells an E-Mini S&P 500 future at 5,000 points and buys it back at 4,980 points. The profit is 20 points.

Long and Short in Futures Trading

In futures trading, long and short positions are equivalent. Since futures are standardized contracts, going short is just as straightforward as going long — no shares need to be borrowed as with stock short selling. The trader simply enters a sell obligation.

This symmetry makes futures particularly attractive for traders who want to profit from both rising and falling markets. There are no restrictions, borrowing fees, or uptick rules like those associated with short-selling stocks.

Long and Short in Stock Trading

With stocks, going long is straightforward: you buy shares and hold them. Going short, however, requires the broker to lend the shares. The trader sells the borrowed shares and later buys them back at a lower price to return them. Borrowing fees apply, and not all stocks are available for short selling.

Risks of Long and Short Positions

Long Position

The maximum risk of a long position is limited to the purchase price — in the worst case, the price falls to zero. The profit potential is theoretically unlimited, as prices can rise indefinitely.

Short Position

With a short position, the risk is theoretically unlimited, as there is no upper limit to price increases. An unexpected sharp price surge (short squeeze) can lead to significant losses. Strict risk management is therefore particularly important for short positions.

When to Go Long, When to Go Short?

The decision between long and short depends on market analysis:

• Long in uptrends, during positive market sentiment, after successful tests of support zones
• Short in downtrends, during negative market sentiment, after rejection at resistance zones
• In sideways markets, both directions can be traded — long at the bottom and short at the top of the range

FAQ

Can retail traders go short?

Yes, through futures, CFDs, or options, short selling is accessible to retail traders. With stocks, it is more restricted and requires a margin account as well as available shares for borrowing at the broker.

What is a short squeeze?

A short squeeze occurs when many traders are positioned short and the price suddenly rises. Short sellers must close their positions by buying back, which drives the price even higher and triggers a chain reaction.

Is short selling riskier than going long?

Theoretically yes, since losses on short positions can be unlimited. In practice, this risk is managed through stop-loss orders and position sizing.
