5个值得关注的空头候选人：Biofrontera重新加入和TOPS榜单，2个新名字进入Leaderboar

Potential short squeeze plays have gained steam in 2021 with new retail traders looking for the next huge move. $GameStop(GME.US)$ and $AMC Entertainment(AMC.US)$ are two high-profile examples of short squeezes earlier this year.

A short squeeze can occur when a heavily shorted stock rises in value instead of falling. Short sellers could be looking to close out their position and can face a loss if they have to buy back the shares they initially borrowed at a higher price.

A squeeze can occur when short sellers are forced on buying in to cover their position, which has caused shares to go much higher on many occasions.

Fintel Data:Data from Fintel, which requires a subscription, provides a look at several of the top shorted stocks and data showing how likely a short squeeze is to occur.

This week's leaderboard includes two names from last week and is topped by a returning name from several weeks ago. Here is a look at Fintel's top five short squeeze candidates for the week of Dec. 27.

Biofrontera: Biopharmaceutical company $AMC Entertainment(AMC.US)$ tops the Fintel short squeeze leaderboard this week. Fintel shows short interest in BFRI shares at three million shares, which represents 47% of the company's public float.

Short interest is up over 1,400% in the last month. A cost to borrow of 180% on shares is among the highest of the week.

Reliance Global Group:Insurance and real estate holding company $Reliance Global Group(RELI.US)$ moves up from third place on the leaderboard last week to a second place position entering this week. Fintel shows 34% of the Reliance Global Group total float short, in line with last week's figure. The cost to borrow on RELI shares is 134% for the week, up from last week's 89%, signaling a higher chance of a short squeeze.

Petros Pharmaceuticals:Men's health pharmaceutical company $Petros Pharmaceuticals(PTPI.US)$ ranks third after leading the way the last two consecutive weeks. Fintel shows 17% of the total float short, with short interest up over 450% in the last month. The cost to borrow on shares remains near record levels. Fintel shows a cost to borrow of 240% on PTPI shares, down slightly from the past two week's respective totals of 254% and 268%.

The stock has several of the highest recorded cost to borrow figures on record. Institutional ownership has declined in PTPI shares over the last few weeks, which could signal bearish sentiment.

Qualigen Therapeutics: Biotechnology company $Qualigen Therapeutics(QLGN.US)$ ranks fourth on the short squeeze leaderboard. Fintel shows 18% of the company's float short, up 258% in the last month. The cost to borrow shares on QLGN shares is 17.3%.

Shares traded over $2.50 in November and saw a slight run last week going from under $1 to the $1.50 level.

Inspira Technologies Oxy: Medical device company $Inspira Technologies Oxy(IINN.US)$ joins the short squeeze leaderboard this week. Short interest has been increasing in the name in recent weeks and is now 9.6% of the company's float. Fintel shows a cost to borrow of 90%, which could be high compared to the single digit percent of float short.

Shares went from $3 to $4.50 last week and traded over $6 in early December. IINN is a small cap stock with a market cap of $28 million.
