Do mutual funds short stocks? Explained
Short summary
Do mutual funds short stocks? Short answer: some mutual funds do employ short-selling strategies and derivatives to profit from or hedge against falling security prices, but most retail investors cannot short open‑end mutual fund shares themselves the way they can short exchange-traded securities.
Quick answer
Certain mutual funds (for example, long–short, market‑neutral, hedged or “bear” mutual funds) intentionally short stocks as part of their stated strategy, but ordinary investors cannot short most mutual‑fund shares the way they short exchange‑traded instruments. The phrase "do mutual funds short stocks" captures two different ideas: (1) whether fund managers place short positions inside a fund, and (2) whether investors can short the fund vehicle itself. The answer to both questions is different.
Types of mutual funds that use short selling
When people ask "do mutual funds short stocks," they are often wondering which fund types actually adopt explicit short positions. Common mutual‑fund types that may short stocks include:
- Long–short equity funds: these funds hold both long positions in stocks they expect to appreciate and short positions in stocks they expect to decline. The manager’s net exposure varies by strategy.
- Market‑neutral funds: designed to remove broad market beta by balancing long and short exposures so that returns depend mainly on stock‑picking skill rather than market direction.
- Hedged or hedge‑like mutual funds: some mutual funds adopt hedge‑fund‑style tools — including shorts and derivatives — within a mutual‑fund wrapper to offer alternative return streams.
- Bear or inverse mutual funds: funds that seek to deliver the inverse of an index’s return over a period may short index components or use derivatives to achieve inverse exposure.
Whether a given mutual fund may short stocks depends on its prospectus and investment mandate. Many traditional actively managed equity mutual funds remain long‑only and explicitly prohibit shorting in their legal documents; others include clear authority to use short sales and derivatives.
How mutual funds short stocks (mechanics)
Fund managers use several methods to establish short exposure. Common mechanics include:
- Borrow and sell short: the fund borrows shares from a lender (often through a prime broker or securities‑lending agent) and sells them in the market; the manager later repurchases shares to close the position.
- Options: buying put options gives downside exposure to a stock without borrowing shares; writing options or using spreads are also used for hedging or directional views.
- Swaps and total‑return agreements: a fund can enter a swap that pays the negative return of a reference stock or basket, transferring short exposure without directly shorting shares.
- Futures and index products: index futures or other derivatives can provide broad short exposure efficiently.
- Inverse instruments: when available in mutual‑fund structures, inverse or synthetic instruments replicate short returns.
Operationally, executing short positions involves margin, collateral and securities‑lending arrangements. A fund that shorts will typically maintain cash or high‑quality collateral and follow internal limits on net and gross exposure. Shorting requires borrowing availability and can be constrained by liquidity of the target security.
Why mutual funds use short selling (purposes)
Fund managers short stocks for several reasons:
- Express negative views: short sales allow a manager to profit if a security declines in value.
- Hedge portfolio risk: shorts reduce net market exposure (beta) to limit downside in falling markets.
- Market‑neutral or relative‑value strategies: combining longs and shorts isolates stock‑picking alpha by neutralizing market moves.
- Enhance returns or reduce volatility: when used skillfully, short positions can add alpha and lower portfolio volatility.
These purposes align with different investor objectives. For example, an investor seeking absolute returns in any market may prefer a fund that uses shorts for directional profit, while an investor looking for volatility reduction may prefer a market‑neutral or hedged product.
Prevalence and empirical findings
Research has examined how common short usage is among mutual funds and what outcomes it produces. Studies such as Chen, Desai & Krishnamurthy’s “A First Look at Mutual Funds that Use Short Sales” provide empirical evidence that:
- A growing subset of mutual funds use short sales and related instruments, with short‑using funds representing a measurable share of assets under management in sample periods.
- In some samples, funds that reported short activity exhibited nontrivial short exposure — studies have documented aggregate short exposure measures on the order of mid‑teens percent of assets in certain datasets.
- Funds that use short sales or hedging techniques have, on average and in some studies, shown the potential to generate abnormal returns (alpha) compared with similar long‑only funds, though results vary across time and by manager skill.
Other empirical findings highlight that funds employing shorts are more sensitive to investor flows and may face different flow‑performance dynamics than long‑only funds. Still, most mutual funds remain long‑only: the use of shorting is concentrated in specialized strategies rather than the majority of open‑end equity funds.

Why most mutual funds do not short extensively
Although some funds short, most mutual funds remain long‑only for a number of practical reasons:
- Liquidity and cash management: open‑end mutual funds must meet daily redemption requests at NAV, which requires liquid portfolios and conservative cash management. Large short positions can complicate liquidity planning.
- Prospectus and mandate constraints: many retail mutual funds explicitly limit or forbid the use of short sales and leverage in their governing documents.
- Risk of theoretically unlimited losses: unlike a long position, a short position faces the possibility of large or unlimited losses if the security price rises, creating risk management challenges.
- Flow management and investor expectations: long‑only products are simpler for retail investors to understand and for distributors to recommend; investors often demand straightforward long exposure.
- Regulatory and operational costs: executing shorts involves borrowing costs, margin, and operational infrastructure that increase expense ratios and complexity.
For these reasons, most mass‑market mutual funds — such as standard large‑cap equity or target‑date funds — avoid active shorting and instead rely on diversification and long‑only risk management.
Regulatory, operational and risk constraints
Short selling by mutual funds is subject to legal, regulatory and operational limits:
- Fiduciary duty and prospectus constraints: managers must operate within the investment policy and prospectus, acting in shareholders’ best interests. Using shorts contrary to stated objectives can create legal and reputational risk.
- SEC rules and historical restrictions: the SEC has implemented short‑sale related rules and has in the past applied temporary short‑sale restrictions in periods of market stress (for example, during crises). These historical episodes show how regulators may limit shorting under stressed conditions.
- Margin requirements and potential margin calls: borrowed positions require margin and collateral, and adverse moves can trigger calls that funds must meet promptly.
- Operational controls: funds establish limits on gross and net exposure, concentration, liquidity thresholds and internal approval processes for short trades.
- Borrow availability and cost: the ability to borrow shares — and the cost to do so — varies across securities and time; hard‑to‑borrow stocks increase execution cost and financing risk.
These constraints shape how extensively a mutual fund can rely on shorting and increase the importance of experienced operational teams.
Can an investor short a mutual fund?
The question "do mutual funds short stocks" is different from "can I short a mutual fund?" For most retail investors the short answer is: generally no for open‑end mutual funds, yes for exchange‑listed funds.
- Open‑end mutual funds: shares of open‑end mutual funds are bought or redeemed directly with the fund company at end‑of‑day net asset value (NAV). Because trading occurs at NAV through the fund company rather than on an exchange, the typical retail investor cannot short an open‑end mutual fund in the same way they short a stock. Some brokerage desks may facilitate certain positions synthetically, but retail shorting of open‑end mutual fund shares is not a standard offering.
- Exchange‑traded funds (ETFs): ETFs trade intraday on secondary markets and can be shorted by investors, subject to broker availability and margin rules. ETFs are often more tax‑efficient and flexible for investors who want the ability to short a pooled vehicle.
If you want short exposure to a mutual‑fund‑style strategy, look for mutual funds that themselves employ shorting (long–short or inverse mutual funds) or consider ETFs and derivatives that permit direct shorting. When considering any vehicle, read the prospectus for restrictions and operational mechanics.
Interaction with external short sellers and market dynamics
Mutual funds that short stocks interact with other market participants, including independent short sellers. Key dynamics include:
- Price discovery: short sellers — both fund managers and independent short‑selling traders — can contribute to price discovery by identifying overvalued securities.
- Opposite flow behavior: academic research finds that short sellers sometimes trade opposite to mutual‑fund flows, exploiting temporary distortions created by flows into or out of mutual funds.
- Liquidity effects: short selling can add to market liquidity in some periods but may exacerbate liquidity pressure during stressed episodes if many participants rush to cover.
Understanding how internal fund shorts and external short sellers operate helps investors weigh the market‑structure consequences of short positions.
Performance, benefits and criticisms
Benefits associated with funds that short stocks:
- Potential for additional alpha: skilled managers can generate positive returns from both long and short selections.
- Hedging and lower volatility: short positions can reduce overall portfolio sensitivity to market downturns.
- Improved price efficiency: shorting helps correct mispricing and can enhance market discipline.
Criticisms and risks:
- Complexity and higher fees: funds that short often employ complex strategies and charge higher fees to cover borrowing and derivative costs.
- Increased potential for drawdowns: shorts can amplify losses if markets move against positions; short squeezes can be particularly costly.
- Flow sensitivity and redemption risk: funds that rely heavily on shorts or derivatives may behave differently when facing large redemptions, which can affect performance.
Empirical studies indicate that while some funds with short exposure have outperformed peers at times, results are heterogeneous: outcomes depend on manager skill, timing, and the cost structure of shorting.
What to check before investing in a mutual fund that uses shorting
If you are evaluating a mutual fund that uses short selling, use this checklist:
- Read the prospectus and statement of additional information: confirm whether the fund is permitted to short, use leverage, or trade derivatives.
- Review historical performance and volatility: compare returns across up‑markets and down‑markets, and pay attention to drawdown behavior.
- Examine expense ratio and shorting costs: borrowing fees, margin costs and derivatives premiums can materially erode returns.
- Assess manager track record and experience with short strategies: look for documented experience in long–short or hedged strategies.
- Evaluate liquidity and redemption terms: ensure the fund’s liquidity profile fits your investment horizon and potential need to redeem.
- Consider suitability and risk tolerance: funds using shorts may not be appropriate for risk‑averse investors who prefer simple long exposure.
- Understand tax implications: some mutual‑fund trading can create taxable capital gains; compare tax efficiency with ETFs when tax matters.
Following this checklist helps you align product choice with investment goals and constraints.
Examples and common strategies
Common implementations of shorting within mutual‑fund wrappers include:
- Pure short/bear mutual funds that seek to profit from falling markets by shorting index components or sectors.
- Long–short equity mutual funds with deliberate net exposure targets (for example, 40% long, 20% short = 20% net long).
- Market‑neutral mutual funds aiming for near‑zero net market exposure and relying on pair trades and relative value shorts.
- Multi‑strategy funds that use shorting selectively alongside derivatives, options and other tools for hedging or opportunistic returns.
Many mutual funds use limited shorts only for hedging rather than as a principal return source; reading fund literature confirms the intended role.

As of 2025‑06‑12, according to MarketWatch reporting on trustee investing and allocation choices, investors and stewards are reminded that ETFs and mutual funds have different trading mechanics and tax profiles; that reporting noted ETFs are generally more tax‑efficient than mutual funds for taxable accounts, a consideration when comparing vehicles that permit shorting or intraday trading.
Further exploration and next steps
If you are researching whether a particular mutual fund shorts stocks, begin with the fund’s prospectus and shareholder reports. For investors who need the ability to short a pooled vehicle directly, ETFs (which trade intraday) may be more suitable than open‑end mutual funds that transact at NAV.
