What is Short selling?
Short (qisqa sotish)
In short
Selling borrowed shares hoping to buy them back cheaper. Losses are theoretically unlimited.
Most Shariah standards (including AAOIFI) do not permit selling what you do not own. Limitup's demo and calculators are long-only.
Also known as: short
Short selling is betting on a price decline. The trader borrows shares from the broker, sells them at the current price, and hopes to buy them back cheaper later (cover) and return them. The difference is profit; if the price rises, it's a loss.
How it works
- Shorting is only possible in a margin account; the broker requires collateral.
- You pay a borrow fee on the borrowed shares; for scarce or heavily shorted stocks it can be very expensive.
- If a dividend is paid while you're short, you owe it to the lender.
- The broker can recall the shares at any time.
The main risk
In a long the price can fall at most to $0, but in a short it can rise without limit — losses are theoretically unlimited. When many traders are short at once (high short interest), a rising price forces them to buy back, which accelerates the rise — a "short squeeze".
Shariah perspective
Most Shariah standards, including AAOIFI, do not permit selling what you do not own; shorting also normally involves interest-bearing margin. That's why Limitup's demo and calculators are long-only.
For information only, not a fatwa.
Example
Illustrative: a trader shorts 100 shares at $50 — receiving $5,000.
- The price falls to $40 and they cover: 100 × $10 = $1,000 profit (before borrow fees).
- At a 3% annual borrow fee, 30 days cost: $5,000 × 3% × 30/365 ≈ $12.33.
- The price rises to $75: loss 100 × $25 = $2,500.
- The price rises to $100: loss $5,000 — 100% of the initial proceeds. At $150 the loss is $10,000 — and that's not a ceiling.
Mistakes and tips
A stop-loss on a short is mandatory, not optional — but a gap can jump it and the loss will exceed plan.
Stocks with high short interest carry big squeeze risk; shorting them is especially dangerous.
Factor in borrow fees and dividend payments — they slowly eat into a short held for a long time.
Frequently asked questions
- How much can you lose short selling?
- Theoretically unlimited, since a stock price has no upper bound. In practice the broker issues a margin call or force-closes the position.
- What is a short squeeze?
- When a heavily shorted stock rises, short sellers rush to buy back to cap losses, and that buying pushes the price up even faster.
- Is short selling halal?
- Most Shariah standards, including AAOIFI, do not permit selling what you do not own. For a specific ruling, consult a qualified scholar.
