Yes, Fidelity does allow short selling, but only in a margin-enabled brokerage account with at least $2,000 in equity. You cannot short stocks in any Fidelity IRA. Once your margin account is approved, you borrow shares through Fidelity’s inventory, sell them at the current market price, and later buy them back to return to the lender, hoping to pocket the difference after borrowing costs, interest, and fees.
What You Need to Open a Short Position
Short selling requires a margin account, which is a separate authorization on top of a standard cash account. You have to sign the Fidelity Margin Agreement, which gives the broker the right to lend out securities and use your holdings as collateral.1Fidelity. Margin and Selling Short Without that agreement on file, Fidelity will only process trades against settled cash.
You apply through the Account Features section on Fidelity.com by selecting Margin and then Manage.2Fidelity Investments. Margin Loans The application asks for your annual income, liquid net worth, and investment experience.
FINRA Rule 4210 sets the floor at $2,000 in equity before any margin activity, including short selling.3FINRA. FINRA Rule 4210 – Margin Requirements Your account has to stay at or above that level at all times. Fidelity can also impose higher internal thresholds for concentrated or volatile holdings, and falling below them can trigger liquidation of your positions.4Fidelity Investments. Trading FAQs: Margin
Short Selling Is Not Allowed in Fidelity IRAs
If you were hoping to short inside a retirement account, Fidelity will not permit it. The Limited Margin Agreement for Fidelity IRAs, which covers Traditional, Rollover, SEP, Roth, and SIMPLE accounts, explicitly prohibits short selling, borrowing funds, and creating a debit balance.5Fidelity. Limited Margin Agreement for Fidelity Individual Retirement Accounts Limited margin in an IRA only unlocks features like trading with unsettled funds and certain options strategies. If a strategy accidentally creates a short position in your IRA, Fidelity will immediately cover it using other assets in the account.
Margin Requirements for Short Positions
Two separate margin rules apply once you open a short: an initial deposit and an ongoing maintenance level.
Initial Margin Under Regulation T
Federal Reserve Regulation T requires you to post margin equal to 50% of the market value of the shares you short, on top of the full sale proceeds. In practice, your account has to hold 150% of the position’s value at the time of the trade: 100% from the sale proceeds plus 50% of your own equity.6eCFR. 12 CFR Part 220 – Credit by Brokers and Dealers (Regulation T) Short 100 shares of a $50 stock, and the $5,000 in proceeds stays in your account while you must also have $2,500 in additional equity.
Maintenance Margin
After settlement, FINRA Rule 4210 requires equity equal to at least 30% of the current market value of the short position for stocks priced at $5 or above. For stocks under $5, the requirement jumps to $2.50 per share or 100% of market value, whichever is greater.3FINRA. FINRA Rule 4210 – Margin Requirements
Fidelity goes further with a house maintenance requirement of 35% on the short side for most securities.4Fidelity Investments. Trading FAQs: Margin Because a short position’s value rises when the stock price rises, your required margin grows along with it. A sharp price spike can push your account below the maintenance threshold even if you started with plenty of equity.
Finding Shortable Stocks
Before Fidelity can execute a short sale, it has to locate shares available for borrowing. SEC Regulation SHO prohibits brokers from executing a short sale unless they have borrowed the security or have reasonable grounds to believe it can be borrowed and delivered by the settlement date.7eCFR. 17 CFR Part 242 – Regulation SHO
Fidelity labels stocks by availability. Those with ample lending supply are Easy to Borrow. Those in limited supply get a Hard to Borrow designation that appears on the quote screen and trade ticket.8Fidelity. Fully Paid Lending When you enter a symbol and select Sell Short, the number of shortable shares shows next to the Quantity field.1Fidelity. Margin and Selling Short If no shares are available, the trade cannot go through until supply returns, and availability shifts throughout the day as other investors open and close positions.4Fidelity Investments. Trading FAQs: Margin
Placing the Trade
To open a short position, choose Sell Short from the Action dropdown on the trade ticket instead of the standard Buy or Sell.9Fidelity. Active Trader Tools Trade Help This tells Fidelity’s system to borrow shares from inventory before selling them on the open market. Limit orders are common for short sales because they let you set a minimum acceptable sale price in volatile conditions.10Fidelity. How to Short Stocks
To close the position, select Buy to Cover from the Action dropdown. That purchases shares on the open market and returns them to the lender. Your profit or loss is the difference between the price you sold short at and the price you bought to cover, minus borrowing costs, interest, and fees.
What It Costs to Keep a Short Position Open
Stock Borrowing Fees
Fidelity charges a fee for lending you shares, and the rate depends heavily on scarcity. Easy-to-borrow stocks typically carry minimal borrow fees. Hard-to-borrow stocks can run substantially higher, with rates that change daily based on supply and demand. These costs eat into your profit even when the stock moves in your favor.
Margin Interest
If your short position contributes to a debit balance, Fidelity charges interest on it. The effective rate depends on the size of the debit and currently ranges from 7.50% for balances over $1 million up to 11.825% for balances under $25,000, based on a 10.575% base rate.11Fidelity Investments. Trading Commissions and Margin Rates Interest accrues daily.
Payments in Lieu of Dividends
If the stock pays a dividend while you are short, you owe the lender an equivalent payment. These payments in lieu of dividends come out of your account and do not qualify for the lower qualified dividend tax rate; they are reported and taxed as ordinary income on the lender’s side.12IRS. Instructions for Form 1099-DIV If you plan to hold through a dividend date, build the payment into your math.
What Can Force You Out of a Position
Margin Calls
When the stock rises, your short position’s value grows and your equity shrinks against the maintenance requirement. Drop below Fidelity’s 35% threshold and you get a margin call for more cash or securities.4Fidelity Investments. Trading FAQs: Margin If you do not meet it promptly, Fidelity can liquidate positions to bring the account back into compliance without waiting for your approval.
Forced Buy-Ins
The shares you borrowed can be recalled by the lender at any time. When that happens and Fidelity cannot locate replacement shares, your short position is subject to a forced buy-in: the broker purchases shares on the open market at the prevailing price to close the position. You bear whatever that buy-in price costs.1Fidelity. Margin and Selling Short The risk is highest with hard-to-borrow names where lending supply can disappear quickly.
The Rule 201 Price Restriction
A federal circuit breaker can temporarily limit short selling on any stock that drops 10% or more from the prior day’s close. Once triggered, SEC Rule 201 only allows short sale orders to execute at a price above the current national best bid for the rest of that day and the entire next trading day.13SEC. SEC Approves Short Selling Restrictions A market order under this restriction will not fill at or below the best bid. Limit orders above the current bid can still execute if the market moves to your price.
Pattern Day Trader Rule
Execute four or more day trades (opening and closing the same position in a single day) in any five-business-day window and FINRA classifies you as a pattern day trader. That raises your minimum equity to $25,000, and the balance must stay in the account before you can keep day trading.3FINRA. FINRA Rule 4210 – Margin Requirements Short-and-cover round trips count the same way long-side day trades do.
Tax Treatment
Profits and losses from short sales are capital gains or losses, but the holding period rules work differently than for regular stock sales. Under 26 U.S. Code 1233, if you hold substantially identical property for one year or less on the date you open the short sale, or you acquire substantially identical property between the short sale date and the closing date, any gain is taxed as short-term capital gain regardless of how long the short was actually open.14Office of the Law Revision Counsel. 26 U.S. Code 1233 – Gains and Losses From Short Sales In practice, most short-sale gains end up short-term.
The wash sale rule also applies. Close a short at a loss and reopen a substantially identical short within 30 days before or after the closing date, and the loss is disallowed for that tax year. The disallowed loss gets added to the cost basis of the new position. Track your activity carefully near year-end.
Why the Loss Side Is Different
The most important thing to understand before shorting anything at Fidelity is that losses on a short position are theoretically unlimited. Buy a stock and your worst case is the price going to zero. Short a stock and there is no ceiling on how high the price can climb, so there is no cap on how much you can lose.10Fidelity. How to Short Stocks A stock that doubles after you short it produces a 100% loss on your original position before borrowing costs.
Price risk is only part of it. Rising prices can produce margin calls on short notice, and failure to meet them lets Fidelity liquidate at the worst possible moment. Borrowed-share recalls can close a position without your consent, even a profitable one. Fidelity notes that short selling is not suitable for all investors.10Fidelity. How to Short Stocks
