"Use Signal" is a tweet that Elon Musk posted last week. He meant to urge people to use the encrypted messaging service app called Signal - Wall Street understood something completely different, pumping the completely unrelated Signal Advance stock (OTC: SIGL) from $0.60 per share (51M mkt cap) to over $70 (6B mkt cap). A 11700% return and a P/E of 990.
