Let's just assume that there are 100 shares of GameStop (worldwide) and go from there. Let's assume that the price per share/stock before all of this was $100 (in a "good" economy, etc.). How would this all work?

A nice timeline, step by step, line by line would be nice. For ex:

1. Stock is selling at $100 per share (100 shares total). June 20XX

2. Economy starts tanking, stock now at $95 per share. August 20XX

3. People start predicting that it will go down further, thus they start "betting" (insert definitions that are accessible and not jargony), etc.

^ something like that would be nice. Thanks!
