Resumo: | Arguably the biggest discount broker in the world, Robinhood implemented in January 2021 trade restrictions on a selection of popular stocks in social media communities, meme stocks. These weretargeted by retail investors in a coordinated fashion to increase their prices above fair value. We examine the impact of restrictions in restricted and non-restricted stocks, focusing on return and abnormal volume. Our model shows that meme stocks underperform when compared to the market and volatility increases around the event. Additionally, the results point towards the presence of herd behavior among retail investors, whose actions promote mis pricing and market inefficiencies. |
