Shares of a small company soared 1100% due to Elon Musk's tweet
Amid news of changes to WhatsApp's privacy policy, Elon Musk, the founder of Tesla and SpaceX, advised his Twitter readers to switch to Signal, a secure messaging app. Investors rushed to buy the service's securities, but confused it with a small company with a similar name - Signal Advance. As a result, the company's shares soared 1100%, writes CNBC. “Use Signal,” read the tweet of the entrepreneur published on Thursday, January 7, which his subscribers perceived ambiguously.
