Kohl’s Corp shares briefly doubled in value to a ten-month high of $21.23 on July 22, making it one of the most traded stocks on retail platforms. The chain became the latest “meme stock,” as the surge in trading was driven by online discussions on platforms like Reddit’s WallStreetBets.

Short squeezes have been a key piece of the stock market rally as short sellers have lost just shy of $355 billion since the market bottom on April 8, according to data from S3 Partners.
