ie day traders will be very happy to trade such a stock. and investors investing in such a stock will be pulling their hair, and gnashing their teeth in despair. I used to day trade stocks. such stock is a day trader's dream. Now I day trade futures.
I didn't like the stock screening part. I was screening the US, Hongkong, Japan, Singapore ... stocks daily. there were like >10 000 stocks to screen. Now I trade futures like US/Asian/Eur equity index, oil, gold, copper, bonds ... futures. no massive screening is required.
GME did go up like $20 but rather weak continuation. Doesn't look like this meme madness is gonna last very long.
