Kohl’s stock traded up as much as 105% Tuesday morning, triggering a temporary halt in trading immediately following the open, likely driven by retail interest.

Shares of Kohl’s Corp briefly doubled in value on Tuesday, as retail traders piled into the U.S. department store chain’s stocks and options, making it one of the most actively traded stocks on retail trading platforms.

Retail investors are largely behind the stock market reaching new records, buying $50 billion in stocks in the last month alone, Barclays estimated.
