Hard-to-Borrow Stocks: What Short Sellers Need to Know

In the world of short selling, access to inventory can define opportunity. Hard-to-borrow stocks are shares that are difficult to borrow, often due to a low float, high volatility, or overwhelming short interest. These names frequently surge during speculative runs or news-driven spikes, making them attractive to traders looking to capitalize on reversals, fades, and other momentum-driven setups.

Traders will find that hard-to-borrow stocks are challenging to execute, meaning that these stocks are recommended only for experienced short sellers who can withstand the high borrowing fees, as well as use the appropriate locates to find the short-supplied stocks to short.

TradeZero, a platform focused on short-selling, gives traders access to real-time hard-to-borrow locates, transparent borrow fees, and routing tools built for fast-moving markets. While hard-to-borrow stocks carry more risk, they can also offer outsized rewards—if they can be accessed in a timely manner. Understanding how hard-to-borrow stocks work is the first step toward navigating this high-stakes corner of the market.

A hard-to-borrow stock is a security that’s difficult to locate for short selling due to limited availability in the lending market. Some stocks have a low number of shares in total. And an even smaller number of borrowable ones, making the stock hard to borrow.

To short that hard-to-borrow stock, the trader is required to locate it, using different locate tools, pay a locate fee, and then finally execute the desired trade.

Hard-to-borrow status typically applies to stocks with low float, meaning a small number of shares available for public trading. These stocks are more prone to sharp moves and heightened volatility.

A unifying factor for all hard-to-borrow stocks is the low supply, however, there is more than one reason for it. The second type of hard-to-borrow stocks is the heavily shorted stocks, which can be caught in sudden hype cycles, pump-and-dump schemes, or sector momentum trends that often land on hard-to-borrow lists.

Finally, active traders must know the difference between hard-to-borrow stocks and easy-to-borrow stocks. Unlike hard-to-borrow, easy-to-borrow stocks are liquid, stable, and available for shorting without special clearance or additional fees. Depending on the type of stock, a complete trading strategy overhaul is required.

Despite the added costs and complications, hard-to-borrow stocks are often magnets for short sellers. Their appeal lies in the unique trading setups they tend to generate, most commonly extreme price action fueled by hype, news catalysts, or retail speculation.

These stocks frequently show up on momentum scanners, gapping up or down in premarket trading or during regular trading hours, drawing attention from traders searching for overextensions and reversals.

Traders will find that hard-to-borrow stocks can sometimes follow a peculiar trend. Usually, there’s a press release, social media buzz, or sudden volume spikes that create a parabolic movement. This can ultimately attract short sellers who are looking to short that pump once signs of exhaustion appear.

On a side note, short selling is difficult enough on its own, and by adding hard-to-borrow stocks to the equation, the difficulty levels rise. As a result, only experienced investors should dabble in hard-to-borrow stocks.

On top of that, hard-to-borrow stocks have a certain barrier to entry, which is shown in the high borrow fees, meaning that investors who are attracted to hard-to-borrow stocks should not only be experienced, but also have a higher investing budget.

Hard-to-borrow stocks are also frequently associated with popular short-selling patterns like the first red day, where a stock posts its first significant drop after a sustained run, or the double top, where a stock fails to break past a previous high. These technical setups offer structured entry and exit points, adding a layer of predictability to an otherwise chaotic space.

As mentioned previously, hard-to-borrow stocks are popular because of the heightened profit potential. However, traders must enforce certain risk management tools and strategies to protect themselves.

The most immediate challenge hard-to-borrow stocks bring is the cost. Depending on how low the supply is and how big the hype is, the borrow fees might prove to be too costly. Borrow fees can impact profit margin if held too long, as the fees are deducted daily.

Secondly, hard-to-borrow shares might not be available. Hard-to-borrow stocks in their core are shares with a limited supply due to a number of different reasons, making it hard for short sellers to acquire the borrowing permit for them.

Lastly, hard-to-borrow stocks are volatile by nature. The volatility is emphasized by the low float and the short squeeze potential. On top of that, low float can trigger violent intraday swings, widening spreads, and increasing slippage. Traders should consider putting stop-loss orders in place to alleviate the risk of a short squeeze.

When it comes to shorting hard-to-borrow stocks, access and speed are everything. TradeZero is built with short sellers in mind, offering tools that address the specific challenges of locating and trading hard-to-borrow shares in real time.

One of the platform’s key features is its real-time locate tool, which allows traders to instantly see if hard-to-borrow shares are available to borrow. This immediate visibility is critical when seconds matter, especially in premarket or high-volatility situations where supply can vanish quickly.

TradeZero offers 3 different versions of locate tools that each serve a specific purpose. The industry standard locates are used for non-threshold securities, allowing traders to short and cover as many times as possible.

Secondly, there is an exclusive feature called Single Use Locates aimed at threshold securities to short and cover only once. And thirdly, there is the Pre-Borrow feature which includes multiple uses and aims to minimize the risk of a buy-in.

Transparency is another advantage. TradeZero provides clear, upfront locate fees and visibility into hard-to-borrow inventory, allowing traders to factor in costs and availability before entering a position. For traders who rely on timing, control, and precision, these tools are not just helpful—they’re essential.

Hard-to-borrow stocks require traders to make decisions fast and have a higher barrier to entry. On top of that, hard-to-borrow stocks can have a tendency to punish hesitant and indecisive investors. To trade them effectively, short sellers need to adopt a more calculated, disciplined approach—one that accounts for both opportunity and risk.

Start by checking borrow fees before entering any position. These fees are dynamic and can vary throughout the day. Knowing the cost upfront helps traders assess whether the trade’s risk/reward still makes sense after accounting for expenses.

Traders must plan their entry and exit. Hard-to-borrow stocks often make sharp, fleeting moves, and waiting for confirmation can mean missing the best price. Short sellers need to put a stop-loss order in action and define a profit target and an exit strategy before the trade begins.

Firstly, and most importantly, short sellers should always use stop-loss orders. Volatility in hard-to-borrow stocks isn’t just common, it’s expected. A sudden reversal can wipe out gains or trigger a margin call.

Secondly, Short sellers should secure the locates early, especially during premarket trading. By the time regular hours begin, the window to borrow shares may already be closed.

Finally, never overleverage on hard-to-borrow setups. Treat them as high-risk/high-reward trades, and size accordingly. Even a textbook setup can go wrong when borrowing costs spike or liquidity dries up.

Hard-to-borrow stocks present unique opportunities for short sellers, including fast moves, major reversals, and high-profit potential. But they also demand precision, discipline, and the right tools.

Understanding how hard-to-borrow stocks work, factoring in the costs, and using a platform that provides a plethora of different real-time locates, like TradeZero, and fast execution can make all the difference.
