Retail investors drive WeWork's meme-stock surge

Retail investors are turning their attention to penny stocks such as WeWork, Amyris, and Proterra, leading to a surge in trading volume and share prices. WeWork, once valued at $47 billion, warned of potential bankruptcy, while Amyris filed for bankruptcy and Proterra filed for Chapter 11 protection. Despite significant losses this week, these stocks saw gains of 40% to 120% as retail traders speculated on potential mergers, turnarounds, and short squeezes. The allure of massive profits in a short period of time is attracting investors, although the risks remain high.
