GameStop and AMC are two companies that make video games and movie theaters. Some people on the internet think these companies will do better in the future, so they buy a lot of their shares to support them. This makes the prices go up, even though some people don't agree with this idea. The person who started this trend is called Keith Gill, who made many videos about it and got a lot of followers. Sometimes, these companies sell more of their shares to make money for themselves. The price of GameStop went up by 4.41% today and AMC by 9.77%. But they are still not as high as they were last week when people were really excited about them. Read from source...

- The article is mainly focused on the recent price movements of GameStop and AMC Entertainment shares, without providing a clear context or explanation for why they spiked on Monday afternoon.
- The article mentions Keith Gill's return to social media as a possible trigger for the rally, but does not explore how his influence has evolved since the initial short squeeze in January 2021, nor how other factors might have contributed to the continued momentum of meme stocks.
- The article relies heavily on sources from Benzinga, which is a financial news and data service that also offers investment tools and products. This creates a potential conflict of interest, as Benzinga may benefit from promoting the volatility of meme stocks to attract more users and customers.
- The article does not provide any analysis or insights on the fundamental value, business model, or prospects of GameStop and AMC Entertainment, nor does it consider the potential risks and challenges that these companies face in the post-pandemic era.
- The article uses emotional language and phrases such as "mania", "fuel", "ultimate", "st", which may appeal to the readers' emotions rather than their rational judgment, or encourage them to take actions based on fear of missing out or herd behavior.
