The market saw a fresh meme stock frenzy this week. While high exuberance can be a contrarian sell signal, sources say the market is still in good shape.

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.

Social media buzzed with excitement on Monday as some beaten-down stocks that retail traders have been buying began to soar. Kohl's, Opendoor Technologies, Krispy Kreme and Rocket Cos. were among the names that posted outsized swings throughout the week.
