What it means
Investors can make money from falling prices by short selling. They borrow shares, sell them and hope to buy them back later at a lower price to return to the lender.
The profit is the difference between the selling price and the repurchase price. Many investors hold positions on both sides at once, so a single number is needed to describe their overall bet.
Net position is long holdings minus short holdings in the same security or market. If long is 10,000 shares and short is 25,000, the net position is 15,000 shares short.
Being net short matters because the risks are different from owning shares. A shareholder can lose at most the amount invested, since a price cannot fall below zero.
A short seller faces a loss that is theoretically unlimited, as the price can keep rising and the position must eventually be closed. Net short numbers are watched closely by regulators and the market.
In some places, investors must disclose significant net short positions, because large short bets can influence prices and sentiment. Futures markets also publish data on how traders are positioned, and a rising net short can signal pessimism or heavy hedging.
A nuance is that net short does not always mean a bearish view. A fund that holds shares in a company but hedges by selling an index future may show a net short position in one instrument while remaining positive overall.
It is the full picture of exposures that tells you what the investor really thinks. For a manager, the concept is useful far beyond the stock market.
Any business that has promised to deliver more of something than it holds, such as a metals trader or an exporter with foreign currency obligations, is net short that item. Knowing the net figure is the first step to deciding whether to cover it or accept the risk.
In practice
Real-world examples.
Example
A hedge fund believes a retail chain is overvalued and sells short 500,000 shares at $12 per share, with no shares owned. Its net short exposure is $6,000,000. If the price falls to $9, the fund gains $1,500,000.
Example
A pension fund holds $50,000,000 of equities and sells index futures worth $60,000,000 to protect against a market fall. It is net short $10,000,000 of equity market exposure. The risk team monitors this closely because a rally would produce losses.
Example
A commodity trading firm has sold forward contracts for 200,000 barrels of oil but owns only 120,000 barrels in storage. It is net short 80,000 barrels. The trader decides whether to buy more oil or accept the risk of a price rise.
Formula
Calculation
Net position = long position - short position
If the result is negative, the investor is net short.
An investor owns 10,000 shares of a company and has sold short 25,000 shares of the same company. Net position = 10,000 - 25,000 = -15,000 shares, so the investor is net short by 15,000 shares. At a share price of $20, the net short exposure is 15,000 x $20 = $300,000. If the share price rises to $24, the loss on the net short is 15,000 x $4 = $60,000.Case study
Seen in the real world.
Marlow Capital is a fictional investment firm, used for illustration only. In this illustrative story, its analysts concluded that a consumer electronics company was heading for a poor year. The firm sold short 400,000 shares at $25, holding 100,000 shares from an earlier investment, which left a net short position of 300,000 shares worth $7,500,000.
Instead of falling, the share price rose to $31 after a surprise product launch. The net short lost 300,000 x $6, which is $1,800,000, and the risk committee ordered the position cut in half. Marlow's chief risk officer later added a rule that no single net short could exceed 3% of the fund's value without approval.
Watch out
Common mistakes.
- Assuming net short means the investor owns nothing. The investor may hold shares but has sold more than they own.
- Believing losses on a short position are capped. The loss grows as the price rises, and it has no fixed upper limit.
- Ignoring borrowing costs. Short sellers pay fees to borrow shares, which reduces profit and adds to loss.
Questions
People also ask.
Is being net short always bearish?
Not necessarily, because it may be part of a hedge that offsets risk elsewhere in a portfolio.
What is a short squeeze?
It is a rapid price rise that forces short sellers to buy back shares, which pushes the price higher still.
Do regulators see net short positions?
In many markets, large net short positions must be reported to regulators or disclosed publicly once they pass set thresholds.
