I liked Ars Technica's analysis of what happened. The TL,DR is that if a company's stock is so heavily shorted, so much so that the number of "borrowed" shares exceeds the number of liquid shared available, and it is not on the verge of going bankrupt, this kind of short squeeze is possible and you can get a feedback mechanism going to make the price soar, at least in the short term.<p>If Wall Street wants to address this, they could put limits on the number of shares that can be shorted.<p><a href="https://arstechnica.com/gaming/2021/01/the-complete-morons-guide-to-gamestops-stock-roller-coaster/" rel="nofollow">https://arstechnica.com/gaming/2021/01/the-complete-morons-g...</a>
