Wilton Risenhoover has been tracking the financial markets for more than a decade, but he has never seen so many retail traders in the stock market until now.
The meteoric rise of meme stocks such as AMC Entertainment (AMC) and GameStop (GME), which were up 2,449% and 1,458% respectively this year as of market close on Tuesday, has drawn experienced traders and first-time investors in the US and abroad.
"We are seeing global interest in these meme stocks in terms of subscriptions and in terms of traffic as well," Risenhoover, founder and chief executive of investment research firm Fintel, said in an interview.
Under these circumstances, his firm has built a powerful tool that aims to identify short-squeeze opportunities for retail investors. The Fintel short squeeze explorer ranks stocks based on their short squeeze scores, which take into account their short interests as a percentage of float, short borrow fee rates, trading volume, as well as other volatility and price momentum metrics.
Risenhoover said he started building the tool after GameStop shares soared into the stratosphere on the back of a short squeeze and gamma squeeze.
"There has always been a general interest in short squeezes over the years because they are really interesting and there's opportunities to make an extraordinary amount of money for a lot of people," he said. "But they happen so rarely and they are so hard to predict."
However, Reddit's 10 million WallStreetBets traders may have broken the mold. As traders shift their focus from one meme stock to the next, even non-traditional meme stocks such as Clover Health (CLOV) and Wendy's (WEN) can suddenly find themselves up 86% and 26% respectively in one day.
Like AMC and GameStop, these stocks have been heavily shorted for a long time but there is no guarantee of a short squeeze until a catalyst comes along, and that's why Risenhoover's model also tracks volatility and price momentum closely.
"You can see companies that are perpetually on the cusp of having a squeeze," he said, "but until you have both price and volume going up, you will not see a short squeeze."
With no further ado, here's a list of the top 20 most heavily shorted stocks primed for a squeeze based on Fintel's multi-factor quantitative model. The stocks, along with their tickers, relative short interests, and borrow fee rates are listed below, and ranked in ascending order of what Fintel calls their short squeeze scores.
