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.

AEO’s Sudden Surge American Eagle Outfitters (NYSE:AEO) has seen its stock soar recently, climbing 12% over the past week, with a 4.5% jump yesterday and another 4.5% gain in early morning trading today.
