LONDON (Reuters) - Retail investor darlings GameStop and AMC Entertainment's Frankfurt-listed shares jumped on Wednesday, in a continuation of this week's rally after posts from "Roaring Kitty" Keith Gill a central figure behind the 2021 meme stock frenzy.

Cinema chain AMC's Frankfurt shares soared 32% in heavy trading volume, having closed up 32% in Tuesday's U.S. trading, while video game retailer Gamestop jumped 26% in Frankfurt, after a 60% Tuesday surge in New York.

Keith Gill, popularly known among traders as "Roaring Kitty", shared a series of cryptic posts on social media platform X on Sunday following a three-year gap.

The posts did not mention company names, but Gill is credited with sparking the so-called Reddit rally in January 2021 with bullish calls on GameStop.
