The group of "meme" stocks, led by videogame retailer GameStop Corp. (GME) that have been volatile in recent weeks as investors on a Reddit subgroup have egged each other on, were active again in premarket trade Monday. 

1. GameStop shares were up 5% premarket.

2. AMC Entertainment Holdings Inc. (AMC), the world's biggest cinema chain, were up 12%. 

3. BlackBerry Ltd (BB.T) was up 3.8%, and 

4. Naked Brand Group Ltd. (NAKD) was up 9.5%. 

5. Koss Corp. (KOSS), a maker of headphones, was up 2.9%. 

GameStop shares have gained 440% in the year to date, as investors on Reddit's WallStreetBets platform sought to punish short sellers who had driven short interest in the stock to 140% by buying the stock and creating a short squeeze.
