Anne Hathaway Accidental Stock Spike

The so-called Hathaway Effect describes how actress Anne Hathaway’s name accidentally affects Berkshire Hathaway’s stock price. When she trends on social media or in online news, automated Wall Street trading algorithms pick up the keyword “Hathaway” and start buying Berkshire Hathaway shares. This activity briefly pushes the stock price up, even though the company has no connection to the actress.
